Inquiry:

We use Case 2 for compliance. According to our calculation for this credit, we think that we need to provide 13 showers. Question 1: How are the showers required to be split between male and female, if not unisex? We split 50:50. Question 2: The building has 617,149 sqft. This number includes all floors, including two roof floors with technical rooms and the lower levels including one floor with only technical spaces. To determine default occupancy count, we divided the building\'s gross square feet by 250 (general office). Do we need to apply this rate to the whole building or can we first subtract the square footage of main technical rooms and/or of complete technical floors (64,600 sqft)? Question 3: Our building is a mixed use building with one multipurpose room and foyer on a lower level, and a small caf

Ruling:

The project is seeking clarification for how to determine the anticipated occupancy of their project for the purposes of Sustainable Sites credit 4.2.The CS Appendix 1 Default Occupancy Counts is required to be used for the project types listed for any CS project that does not know actually occupancy numbers. The numbers are based on average gross square foot per occupant of buildings of that type and include support spaces such as lobbies, mechanical room, storage and other non-rentable spaces. Large, unoccupied areas that are not typical of most projects, such as below grade parking garages, may be excluded from the gross square footage for the purpose of the occupancy calculations. However, projects which exclude any portion of the gross square footage must provide a supplemental narrative stating the portion of the project and providing an explanation on why this area is not typical for most projects of that type, and why the area should be excluded from the calculation. For mixed use projects, the project should first determine the percentage of the building that is each use. Then the gross building area should be divided up based on those percentages, this will allocate common areas, such as foyers and mechanical spaces, proportionally between the different uses. The project should note that the Appendix 3 LEED-CS Project Scope Checklist, which is required to be submitted for certification and precertification, can assist with this calculation. For building types that are not covered under the Appendix 1 defaults, the project must determine the typical gross square foot per occupant for the building type to use. For example, this can be done through case study of similar type projects, discussions with tenants, or research of publish industry standards. It may also be noted, that the LEED 2009 Reference Guide for Green Building Design and Construction Appendix has an expanded table with additionally occupancies. This table is not required to be used by LEED-CS 2.0 projects, however may be used in lieu of project determined defaults if the project chooses. For restaurants, the default is for FTE is 435 gross square foot per occupant and 95 gross square foot per occupant for transient visitors. There is a known template error for this credit. The calculations provided have been done correctly, and the project should attach the supplemental calculations as shown above for certification. For projects that have an odd number of minimum required showers that wish to divide them between genders, such as the 13 total or 6.5 per gender for this project, the project can either provide an additional shower, 14 total or 7 per gender, therefore meeting the minimum requirement for each gender or can provide a unisex shower that would be usable by either gender.

Inquiry:

Under LEED-CS v2.0, Case 2, for projects with a total gross square footage greater than 300,000 square feet, provide secure bicycle storage for 3% of the occupants for up to 300,000 square feet, then an additional 5% for the occupants for the space over 300,000 square feet. This calculation is done for each use of the building in mixed-use projects. Projects must also provide shower and changing facilities in the building for 5% of Full-Time Equivalent (FTE) occupants. Our project consists of 900,000 square feet of office space and 60,000 square feet of retail space. Since the tenants are unknown, occupancy has been calculated using Appendix 1 - Default Occupancy Counts in the LEED-CS v2.0 Reference Guide. Our calculations project 3,600 FTE for office space and 109 FTE for retail space. This requires a total of 210 secure bicycle storage units which will be included in the Core and Shell project. However, the building tenants are unknown. We do not feel it is appropriate to provide shower facilities for an estimated 3,709 occupants as part of the Core and Shell project. Instead of placing 186 shower facilities in a central location, we propose recommending the shower requirement in the tenant guidelines, requiring that each tenant provide shower and changing facilities for 5% of their employees. This will allow the tenants more flexibility to meet spatial and functional requirements, including the location and number of showers. The design team and the owner feel that the intent of the credit is met by this solution. Please rule on whether this approach is acceptable.

Ruling:

As noted in the LEED-CS Rating System introduction (page 8), an owner can choose to make specific lease requirements a part of the tenant negotiations, and if these requirements meet the criteria of a particular credit in the LEED-CS Rating System, the LEED-CS project itself may be able to achieve this credit even if the work is not a part of the core and shell design and construction. The project would need to be able to demonstrate that the lease language requires (rather than recommends) that the build-out of the respective tenant spaces includes sufficient shower and changing facilities for 0.5% (not 5% as noted above) of the Full-Time Equivalent (FTE) occupants. If the owner elects to provide these for the tenants, they will need to provide 19 showers for the anticipated FTE number of 3,709 occupants. It should also be clarified that the number of bicycle storage units has also been miscalculated, and should be based on the credit requirements of 3% of the occupants for up to 300,000 square feet, then an additional 0.5% (not 5%) for the occupants for the space over 300,000 square feet.

LEED Interpretation
Inquiry:

We are requesting a ruling on an alternative approach to calculating required bicycle storage for SS Credit 4.2 for a professional hockey arena. Occupancy for the facility is expected to be as follows: FTE: 115 Peak event staff: 700 Peak spectators: 18,500 Peak players: 25 Total: 19,340 Bicycle storage to serve all guests and staff who are likely to be at the arena during a sold-out game, would amount to 967 storage spaces if the credit requirements were followed as written. However, for reasons similar to those presented in the Credit Interpretation Requests dated 9/12/2007 and 10/5/2007 the project team feels that it is impractical to impose the same bicycle storage rules for this facility as for office buildings, namely: - Transient occupants tend to attend sporting and entertainment events in groups rather than as individuals. - This project has ample public transportation within 1/4 mile of the site. - The largest events occur in the evenings in the winter, times during which cycling is not ideal for safety and comfort reasons. - Similar facilities, such as the SF Giants described in the 9/12/2007 CIR, have demonstrated that current demand for bicycle storage is significantly lower than what SS Credit 4.2 requires. - The land required to provide permanent bicycle storage that has little likelihood of being used is not an ideal usage of the site. The project team proposes two ways of providing bicycle storage quantity that will adequately serve the realistically expected current demand for this facility while allowing for capacity growth based on peak demand. 1. To establish the current demand for transient occupant bicycle storage, statistics from a local non-profit cyclist organization whose mission is "to establish [a] city that is increasingly safe, accessible, and friendly to bicycle transportation" will be used. This organization states that the current rate of commuting by cyclists to the arena neighborhood is 0.8%. Applying this statistic to the peak occupancy stated above, 154 bicycle storage spaces would be needed for events. To accommodate 125% of this estimated demand, a total of 194 bicycle storage spaces would be provided using permanent and/or valet bicycle storage. Over time, peak demand will be monitored such that bicycle storage provided always exceeds demand by 25% until the maximum bike storage capacity of 5% of peak building users (or 967) is met. OR 2. To establish the current demand for bicycle, the team management will survey staff and season ticket holders to determine: a. The number (and percentage) that currently travels to events via bicycle b. The number (and percentage) who would consider traveling to events via bicycle if secure storage were provided at the arena Based on the survey results, enough permanent and/or valet bicycle storage will be provided to accommodate 125% of current demand. Each season, peak demand will be monitored such that bicycle storage provided always exceeds demand by 25% until the maximum bike storage capacity of 5% of peak building users (or 967) is met. For both approaches above, shower/changing facilities will be made available for 0.5% of all FTE occupants. If a valet service is used it will be implemented considering the requirements in the CIR ruling dated 10/24/2007.

Ruling:

The project team is requesting guidance on two alternative approaches to calculating the number of bi-cycles to be accommodated with secure bicycle storage for a professional hockey arena. The project has proposed 2 approaches, both resulting in the provision of 125% of the current estimated bicycle parking and storage needs, with regular monitoring to ensure available bicycle parking and storage exceeds demand by 25% until the credit requirement— providing bicycle storage for 5% of the building occupants—has been met. Approach 1 is based on the based on statistics gathered from a local biking advocacy organization, whereas Approach 2 is based on a survey of staff and season ticket holders. Either strategy is acceptable, as long as documentation of the process includes detailed calculations, and a description of how the current bike capacity was determined. The project team must also show how the bicycle storage will be monitored and demonstrate the capacity for future expansion exists, should it be needed, as stated in LEED NC 2.2, SSc4.2 CIR ruling 10/24/2007. The alternate strategy outlined is acceptable for large special events facilities only, because of the particular nature of these projects.

LEED Interpretation
Inquiry:

Our firm is currently working on a project designated as a port of entry from Mexico to the US. We are requesting a clarification on how occupants should be calculated in SSc4.2. CIR Ruling (9/14/2006) established that "Excluding a certain type of transient occupant from the required bicycle stall and shower calculations is permissible per previous v2.1 CIR Rulings dated 6/4/2003 and 8/7/2002. Please include a short narrative indicating the number of visitors who have been excluded from these calculations and an explanation of why this type of visitor cannot reasonably be expected to arrive at this destination on or with a bicycle that would benefit from onsite storage facilities." These CIRs related to projects which were destination resorts and airline terminals. Our project, a US Port of Entry, has similar occupancy concerns that make it impractical to provide bicycle racks for all transient occupants. The vast majority of transients are typically crossing from Mexico into the US and are only passing through the facility. They consist of pedestrians or transients entering via automobile or motorcycles. If transients are commuting via bicycle they would typically not be spending time at the facility but merely passing through. This project anticipates achieving SSc4.1 (numerous bus lines within 1/4 mile and a rail line within 1/2 mile) and SSc4.3 and 4.4 (preferred parking for carpools and efficient vehicles). In addition to the previous credits this project will also obtain credit for SSc4.2. This project has 120 FTE and 22,720 transients. Using the above CIR Ruling, the occupant calculation would require 1,142 Bicycle Racks. However, in light of the fact that we believe the majority of the transients would simply be "passing through" this calculation seems excessive for this project. Our project team has identified the following option to address the intent of SSc4.2 and we would like to get direction from the USGBC on the following option: Provide bicycle storage for 5% FTE Showers will be provided to meet the requirement of 0.5% of FTE staff. The project team feels that this approach meets the intent of SSc4.2 for this type of facility. We respectfully request that the USGBC confirm that our approach is valid or provide clear guidance on how our assumptions should be modified to meet the intent of SSc4.2.

Ruling:

Providing bicycle storage for 5% of FTE and showers for 0.5% of FTE is an appropriate approach given the project circumstances and that other transportation credits are being pursued to accommodate the FTE and transient occupants. The exclusion of occupants who are passing through only to cross the border is in line with previous CIR rulings. When submitting the credit please include a short narrative indicating the number of visitors who have been excluded from these calculations and an explanation of why this type of visitor cannot reasonably be expected to arrive at this destination on or with a bicycle that would benefit from onsite storage facilities.

Both the NCv2.2 Reference Guide (p56 2nd edition) and the LEED Online template for SSc4.2 ask for a teams to provide "residential FTE". How are teams to calculate this figure, as the reference guide does not seem to provide guidance for calculating residential FTE?

Ruling:

Per the LEED NC v2.1 SSc4.2 ruling dated 12/9/2005, occupancy should be calculated using the number of bedrooms in the case of residential projects. Project teams should provide a narrative with calculations demonstrating how the total number of residential FTE occupants was calculated including indication of number of units, size of units (e.g. studio, one bedroom, two bedroom, etc.), and assumptions as to number of occupants per each size of unit.

LEED Interpretation
Inquiry:

It appears that the LEED criteria may be developed for a more generic office situation and our college campus operates very differently. There are several extenuating factors. Unlike most similar higher education institutions, Colorado College has maintained a relatively constant student population as mandated in the school\'s educational charter. Therefore, an additional building does not imply more students although may indicate additional educators and support staff. Colorado College is a small residential campus requiring ~75% of the students to live in campus housing (all students except seniors must live on campus), which is on contiguous property and within easy walking distance, ~ 1/4 mile. A portion of the professors are also visitors, living in campus housing during their instructional Block (this reduction has not been entered into the calculation). The use of automobiles to attend daily classes is minimal, due to the very short distance. Colorado College operates educationally under the "Block Plan" where only one class is taken at a time for a three and one half week duration in a dedicated Classroom; generally, there is only one class per Classroom per day. The actual usage of the space as compared to the FTE (full time equivalent) students is realistically less than one when considering the primary classroom session generally is in the morning (this reduction has not been entered into the calculation). A maximum of 25 students is allowed per class, so this number is used in the following calculations but the actual students per class will average less (this reduction has not been entered into the calculation). The following numbers are based on actual Classroom and Office room counts for the Tutt Science Center. --437 students count or ~110 adjusted students count when only 25% arrive from the surrounding community --35 professors and support staff when assuming 100% arrive from the surrounding community --437 + 35 equal 472 total building population --110 + 35 equal 145 adjusted total building population Our question is, can we use the 472 people as our total building population, while using the "adjusted" or "commuter" population for determining showering facilities and parking requirements? This would mean that 472 would be used to determine bike rack needs, which seems appropriate as the on-campus students may also ride bikes for a short distance, while 145 would be used as the building population when determining showering facilities, number of parking spaces, and also the number of alternative refueling stations. For example, using the total population for the bicycle storage capacity would give .05 x 472 equals ~24. Considering the short travel distance for most, shower usage should be minimal and the 145 adjusted building population seems realistic. The resulting count of .05 x 145 / 8 equal ~ 1 shower should be a more accurate appraisal of the potential use.

Ruling:

Showers Per previous inquiry, 0153-SSc42-081701, the LEED Steering Committee has ruled: "Although, transients are required to calculate the bike storage capacity, they shall not be required to be included in the occupant count for calculating the number of showers/changing areas. Transients are defined as visitors to the building for less than 7 hours." Therefore, providing showers based on full time staff or staff FTE will meet the requirements of this credit. Parking If the campus master plan is designed such that 75% of students do not drive to class, and essentially have parking already provided for them adjacent to their housing, their parking needs are already met. The remaining 25% of students and 100% of staff can be used as the \'occupancy\' to calculate required parking and alternative fueling stations. Applicable Internationally.

LEED Interpretation
Inquiry:

This is an inquiry about the calculation of the FTE in relation to our project in Zurich, Switzerland. In the LEED Reference Guide on page 53 the calculation of the FTE is based on a 8-hour working day. That means that an 8-hour occupant has an FTE value of 1.0. The standard working day in Switzerland contains 8.5 hours of work.In a FTE calculation on the basis that is provided in the LEED Reference Guide the normal working day of one single person would have the FTE value of 1.0625. As a consequence of the, in case of 1000 people fulltime staff this FTE calculation would have additional number of 63 FTE in comparion to an FTE value of 1.0.Is it possible to calculate the FTE value for this project with an 8.5 instead of 8 hour day, so that we would have the FTE value of 1.0 for a standard 8.5 hour-working day?

Ruling:

The project team has inquired if projects in Switzerland may use 8.5-hours as their working day instead of 8-hours as in the US. Each full-time employee based on Swiss and US labor laws works an 8.5-hour day, which includes a half-hour unpaid lunch break and two 15-minute paid breaks. In order to maintain the baseline for projects everywhere when calculating FTE occupancy, all Swiss projects, including those industries that have an overtime work culture for full-time employees, should still use the 8.0-hour work day in their FTE calculations.

Inquiry:

There are a number of credit inquiries that relate to the shower requirements at college or university campuses, and as a result, the USGBC has expanded the proximity of changing/shower facilities to the project site from being required on the project site, to being required within 100 yards of the building, to the current standard of being required within 200 yards of the building. This credit inquiry seeks to have Sustainable Sites Credit 4.2 awarded by demonstrating that the intent of the credit is being fully achieved even if the specific distance limit is not. Our project is the renovation of the S.T. Dana Building Renovation, home of the School of Natural Resources & Environment at the University of Michigan, Ann Arbor. Dana is located in the central campus area facing onto the University\'s main quadrangle, know as the Diag. This area of the campus is served by a very large recreational and athletic facility, The Central Campus Recreational Building (CCRB). As an athletic facility, the CCRB provides a substantial number of locker rooms and showers for use by faculty, staff and students on the Central Campus. The CCRB is located roughly 300 yards from the Dana Building. It is easily within a 5 minute walk or a quarter mile of the building, which is the maximum distance LEED allows for walking to a building from public transit. This arrangement currently serves the biking population at the Dana Building with success as demonstrated by the transit survey conducted during the LEED project implementation. A transit survey conducted in April 2002 determined that the current biking population of the Dana Building exceeds the minimum of 5% required for this credit by 22%. - Number of respondents: 171 or 41% of the peak occupant load. (21 faculty; 39 staff; 111 students) - Number of respondents who bike from home to campus: 47 or 27%. Without showers in the building, this exceeds the LEED target by 22%. - Number of respondents who use their bikes to travel around campus during the day: 32. - The survey asked "if you had access to showers, would you be more likely to commute to school/work by bicycle or foot?" 124 or 72% said No. The transit study further determined that the average commute to campus is 6.1 miles and the average commute during the day around campus is 1.2 miles. The peak load occurs during the academic school year, September through May. The climate of Ann Arbor, Michigan, is such that showering after relatively short bike commutes is not necessary, like it might be in a southern and hot, humid campus. The minimum required number of bicycle racks is met within the LEED project boundary; numerous additional racks are provided within 200 yards of the building. The transit survey clearly demonstrates that the intent of this credit has been met at the Dana Building, even though the specific distance requirements are not met. Would this credit be awarded on these grounds? We also request confirmation that our peak occupant load and non-transient occupant load calculations are appropriate. They are as follows. 53 Staff (8 hr/day) = 53 Non-Transients and 53 FTE Occupants (peak load) 57 Faculty (8 hr/day) = 57 Non-Transients and 57 FTE Occupants (peak load) 81 PhD Students (6 hr/day) = 0 Non-Transients and 61 FTE Occupants (peak load) 185 Master (Except LA) Students (4 hr/day) = 0 Non-Transients and 93 FTE Occupants (peak load) 235 Undergraduate Students (2 hr/day) = 0 Non-Transients and 59 FTE Occupants (peak load) 60 Master of Landscape Architecture Students (8 hr/day) = 60 Non-Transients and 60 FTE Occupants (peak load) 29 LS&A (4th Floor) (8 hr/day)= 29 Non-Transients and 29 FTE Occupants (peak load) 700 Total = 199 Non-Transients and 411 FTE Occupants (peak load) Based on 411 FTE Occupants (peak load), secure slots are needed for 21 bicycles (5% min). Based on 199 Non-Transients, two showers are needed.

Ruling:

The transit survey provides clear evidence that there is a sizable bicycling community at the campus, and sufficient bicycle racks have been provided for these cyclists. However, based on the credit requirements and previous CIRs on this issue, the showers that are located 300 yards from the project unfortunately cannot be used to capture this point. Your calculation methodology used to determine the number of FTE building occupants and non-transient occupants is acceptable and consistent with guidelines provided by previous CIRs for this, including the ruling dated 8/7/2002.

LEED Interpretation
Inquiry:

This CIR is in reference to FTE calculations for a multi-floor hotel in a high-density urban setting. FTE calculation for full-time and part-time employees of the hotel can be calculated using actual numbers. Transients as defined by the USGBC are visitors to a building for less than 7 hours. However, this does not always apply to the variable number of guests or the variable amount of time guests will stay in a hotel on a daily basis. The American Hotel & Lodging Association (AH&LA) is the sole national representing body of all sectors in the lodging industry. The AH&LA has lodging occupancy tracked on a weekly basis (research performed by Smith Travel Research). The AH&LA 2006 annual report calculates the year-end lodging occupancy at 63.4%. In a CIR request dated 10/27/2005 (ruling dated 12/9/2005), occupancy for residential projects allows for FTE calculations based on number of bedrooms: 2 regular occupants for a one-bedroom unit, 3 for a two-bedroom unit, and so on. Therefore, since occupancy rates are highly variable for hotels, can FTE be calculated based on the number of rooms x average occupancy/room (e.g. 2) in a hotel multiplied by an average lodging occupancy percent (per the AH&LA) to obtain the transient occupant calculation? For example: 200 units x 2 guests/unit = 400 total guests; 400 guests x 60% (average of the AH&LA information) = 240 calculated transient occupants. This number would then be the transient occupant count added to the calculated FTE of employees for the occupant value for LEED calculations.

Ruling:

Your FTE approach seems reasonable based on the variable transient occupancy of a hotel, and you are encouraged to utilize it. Please note that previous CIRs have ruled that certain transient populations can be excluded from the calculations in determining the number of required bike storage spaces and showers for this credit. Please refer to CIR ruling dated 9/14/2006 for additional guidance. Applicable Internationally.

Inquiry:

We are seeking clarification on the requirements for mixed-use residential projects seeking SSc4.2 - Alternative Transportation, Bicycle Storage and Changing Rooms. The clarification is sought for both LEED-NC 2.1 and 2.2 projects. A recent certification review ruling indicated that changing/shower facilities must be provided for the mixed-use residential building concierge and maintenance staff serving the residential portion of the project. We believe that the language in the reference guide and existing CIR rulings make it clear that it is not necessary. There is no specific reference standard for mixed-use residential buildings. All such projects have been instructed to use LEED-NC. The requirements for mixed-use residential buildings are the same in both LEED-NC Version 2.1 and 2.2. In both, it says: "For residential buildings, provide covered storage facilities for 15% or more of the building occupants in lieu of changing/shower facilities." Therefore, the Reference Guide is clear that all residential buildings do not need to provide showers/changing rooms for the building staff and must instead provide covered bike storage for 15% of the building occupants. For mixed-use buildings with unfinished tenant spaces, CIRs have established that a project team must provide a tenant improvement manual with guidance on how to integrate green strategies into their build-outs and information on pursuing LEED-CI certification. A CIR ruling from 4/4/2005, written specifically for SSc4.4, goes further to clarify: "If the mixed-use building is less than 10% commercial square feet, the entire building can be considered residential and adhere to the residential requirements. Otherwise, the commercial component is to adhere to the commercial requirements, while the residential component is to adhere to the residential requirements." The CIR ruling provides two important clarifications on the shower/changing facility issue. First, if a mixed-use building square footage is more than 90% residential square feet, the ruling indicates that a project team is not required to provide showers/changing facilities in the building as per the credit requirements listed above. Second, if the residential square footage of the mixed-use building is less than 90% of the total building square footage, then showers/changing facilities must be provided for the commercial portion of the building, and "the residential component is to adhere to the residential requirements." Since the concierge and maintenance staff are part of the "residential component", the project team is still not required to provide shower/changing facilities for them. As supported by the CIR, it should be left up to the discretion of the project team if a shower/changing facility for the residential building staff is warranted. Based on the SSc4.2 credit language and the excerpts from the CIR Ruling from 4/4/2005 as explained above, it is clear that a project team is not required to provide a shower for the concierge and maintenance staff in a mixed-use project. If the USGBC wishes to ensure that shower/changing facilities are in fact provided for the building concierge and maintenance staff in mixed-use projects, an addenda revising the credit language for residential buildings is necessary since the Reference Guide currently establishes that for residential buildings, additional bike storage must be provided "in lieu of changing/shower facilities." If the USGBC does issue an addenda revising the credit language for residential buildings, we respectfully request current residential projects registered under LEED-NC 2.1 and 2.2 shall not be retroactively penalized or excluded from achieving the credit provided they meet the existing Reference Guide requirements. It is a good idea to provide the shower/changing facility for the building staff where practical. Any opportunity to provide incentive for use of alternative means of transportation will make a positive contribution towards our collective future. However, it is extreme to disqualify a project from receiving credit because a shower was not provided for as few as three of the building occupants even though the project met the stated requirements and facilitated bicycle riding for hundreds of occupants.

Ruling:

The project is seeking clarification regarding the requirements of SSc4.2 for mixed-use projects. While showers/changing rooms are not required for building staff in a residential building (or the residential portion of a mixed-use building), building staff must be counted as "occupants" when determining the number of bike parking spaces provided in these buildings.

Inquiry:

Our project is a 14 story residential building located in MD. Of the building is 152,740 sf with 150,340 sf of residential and 2,400 sf of ground floor retail. The main building occupants will be the 343 residents. The retail space, which for this project\'s purposes is core and shell space, will be occupied by an estimated 5 retail employees, and 19 retail transients.Our question is in regard to the shower requirement of SSc4.2. Given that the retail space comprises only 1.5% of the total floor area of the project, and will be served by only 5 employees, we propose that the project not be required to provide showers and changing facilities for the retail employees. The project will provide bike racks for the residents (343 residents x 15% = 52 bikes), as well as retail employees and retail transients (24 retail employees/transients x 5% = 2 bikes).To support this proposal, we draw on a previous CIR Ruling dated 4/4/2005 which stated that, "If the mixed-use building is less than 10% commercial square feet, the entire building can be considered residential and adhere to the residential requirements."

Ruling:

The Project Team is inquiring whether the shower and changing facility requirements of SSc4.2 can be exempt for the retail area of a mixed use building where the retail area comprises approximately 1.6% of the total building area. For guidance on this issue, the project should refer to LI 10209 which describes how mixed-use projects with a nonresidential square footage of less than 10% and no greater than 5,000 square feet can document credit compliance. Regarding the use of Retail Supplement compliance paths, since rating systems are comprehensive, substituting the Retail Supplement\'s credit requirements for parts of a building project is granted on a case-by-case basis. Given the allowance provided by LI XXXX, it would not be an appropriate to allow additional approaches to documenting credit achievement.

Our project is a Senior Assisted Living Facility registered under the LEED NC 2.2 rating system. In addition to the residential component it includes a restaurant, shop and dining room and will be staffed 24 hours a day with a maximum of 22 staff FTE occupants per shift. We are requesting a ruling excluding the requirement to provide covered bike racks for the residential occupants, whom are unable to bike due to physical limitations and/or health problems. Due to the specific characteristics of the residential population, the project team feels that it is impractical to provide covered bike storage for 15% of the residents, as calculated for SSc4.2 Alternative Transportation, Bike Storage and Changing Rooms. Previous CIR rulings dated 6/4/2003 and 9/14/2006 set a precedence to exclude certain populations from the bicycle storage requirements based upon the practicality of that population to take advantage of the bicycle storage. LEED for Schools also addresses the issue of physical inability and/or safety by limiting the bike rack requirement to students above third grade. To meet the intent of this credit we are proposing that we satisfy the requirements to serve the employees of the project and provide bicycle storage for 5% of the FTE and showers for 0.5% of the FTE and exclude the residential population from the calculation for bicycle storage.

Ruling:

The CIR is requesting that their project be exempted from the requirement for covered bicycle racks for 15% of residents. This request is based on the physical limitations of the residents at this senior assisted living facility and the assumption that they will not be riding bicycles with any regularity. The project has proposed to meet the credit by providing bicycle racks for 5% of the staff FTE, and showers for .5% of the staff FTE, with the residents entirely excluded from the calculations. Based on previous CIRs, especially the ruling dated 12/2/07 under SSc4.4, physically incapacitated residents can be excluded from credit calculations determining bicycle racks. However, in order for the credit requirements to be satisfied, the bicycle racks must be sized to accommodate 5% of both the FTE staff, and the peak transient occupancy including visitors. The proposal to size the showers for 0.5% of the FTE staff is appropriate for credit compliance. Please note that employee shower facilities must be separate from resident shower facilities.

Inquiry:

Our building is located on a 1,275-acre university campus among 79 buildings with dozens more in the planning stages. The university has 1,065 support staff, 750 faculty (or 1,435 FTE) and 23,464 peak-period transient students/visitors. Adequate bicycle storage can be easily provided for each building, but providing showers and changing rooms is our challenge. Based on the number of FTE\'s, eight showers would need to be distributed among each of the 79 buildings (see related AGMBC notes). The 200-yard distance maximum would not be possible to maintain for the eight showers required (based on 1,435 FTE\'s) distributed in zones among 79 buildings and therefore the number needed to comply with the requirement for each building would significantly increase by a factor of four times or more. This is not a feasible strategy for the university and also not a good use of resources. However, there are two centrally located facilities on campus with showers to which staff and faculty have unlimited access. The Indoor Recreation Facility has 12 shower heads in 4 areas and the Field House has 143 shower heads in 9 areas. These facilities are linked together with 5 free bus/shuttle lines that operate in 7 to 8 minute intervals between the hours of 7 am and 7 pm. This strategy is analogous to the compliance path for credit EAc4.1 Alternative Transportation: Public Transportation Access, which allows the use of shuttles to connect to primary bus and rail systems. Please confirm that the use of centrally located showers accessible by shuttles is an acceptable alternative to the 200-yard maximum.

Ruling:

The project is requesting that showers farther than 200 yards from the building entrance be acceptable because of the free campus shuttle service available. This is not an acceptable alternative compliance path. In order to make bicycle commuting a viable and attractive option for building occupants the showers must be within 200 yards of the building entrance. Please note that the project need only provide showers for 0.5% of FTE of the project itself, not the entire campus. Applicable Internationally.

Inquiry:

Our project is a dormitory village on a university setting in Phoenix, Arizona. We intend to provide the residents and staff with more than the requisite number of bike racks in fully-covered, secure and easily-accessible locations. Our question pertains to the definition of covered. It is typical in the Southwest to provide protection from the elements with vegetation. We intend to plant mesquite trees, which have a canopy of 25\'-35\', and will completely cover the bike rack area to provide shelter. Is this an acceptable approach to meet the requirements of this credit?

Ruling:

Consistent with CIR ruling dated 5/9/2005, this approach will not meet the requirements of SSc4.2. It is not clear how long it will take for the mesquite trees mentioned to provide a large enough canopy to provide cover for the bike racks. Using trees as cover for bike storage does not ensure that bicycles will not be exposed to the elements. Covered storage areas protect bicycles from sun and rain, providing more of an incentive for their use in lieu of automobiles. Applicable Internationally.

Under LEED NCv2.2, projects must provide adequate bike racks to serve 5% or more of all commercial and retail building users at peak periods of occupancy and shower and changing facilities for 0.5% of Full-Time Equivalent (FTE) occupants. The credit also requires residential projects to provide 15% of residents with covered bike storage. Our project is a mixed use hotel, residential, retail and office building in New York City. We propose to provide: - Bike racks for at least 5% of the hotel and retail employees, retail customers and office tenants - Showers and changing facilities for at least 0.5% of the hotel and retail staff and office occupant FTE - Covered bike storage for at least 15% of residents - Hotel guests with information about where they can rent a bike for daily use We request exemption of the hotel guests from the onsite bike storage requirement as we do not believe they will bring bikes and it would be cost prohibitive to provide enough bike storage to serve 0.5% of them. The USGBC has previously ruled (SSc4.2 ruling dated 06/04/03) that an international airline terminal can meet the intent of this credit by providing bike racks, showers and changing facilities for the FTE staff occupancy exclusively, provided alternative transportation opportunities are maximized for transient occupants. In addition this would be extremely cost prohibitive based on the construction and real estate in New York City. Our project is located on 42nd Street, very near Times Square in midtown Manhattan. The primary modes of transportation around this busy retail, theatre and residential area are walking and subways. The project itself includes a new subway station that will lead pedestrians to 12 subway lines. The City\'s major bus terminal (Port Authority) is a block away from the project. The City\'s two major train stations are within walking distance, but hotel guests can also catch a pedicab, bus or subway from the project to reach them. We do not believe personal bicycles are a likely means of transportation for hotel guests (especially from the airport with luggage) to our project, and guests will have every means of reaching the hotel by public transportation. Out of town guests will be able to reach the project by subway, train or bus from all the major New Jersey and New York airports.

Ruling:

The project team is pursuing LEED- NCv2.2 SSc4.2 and is requesting an exemption for hotel guests from the onsite bike storage requirement. Per previous CIR ruling (NCv2.1 SSc4.2 ruling dated 09/14/06), the proposed approach to exclude hotel guests from onsite bike storage requirements is appropriate given the proximity of the project to mass transit and the explanation provided. When submitting this credit, the narrative should include the number of people that are excluded from SSc4.2 occupancy counts and why this type of visitor cannot reasonably be expected to arrive at this destination on or with a bicycle. The submittal should also state how guests with bicycles will be accommodated. See the LEED NCv2.1 SSc4.2 CIR ruling dated 5/13/2007 for information on calculating hotel occupancy. As you correctly mention, other transient occupants such as retail customers should be included in occupancy counts, along with all the FTEs (all building staff and office tenants) and building residents.

My question isn\'t necessarily about Credit 4.2. It\'s mostly about the definition of the site boundary. I have reviewed previous CIRs and from that I learned the site definition needs to be consistent with all credits.My project is two adjacent buildings which will be certified separately; their construction schedules are the same.Here\'s my question. If there are showers in one building does the second building need showers also? It is within 200 yards of other building. Again, both buildings are seeking LEED certification and their schedules are the same.A second related question relates to SS Credit 6.1. We\'re considering a cistern. Do both buildings need one to get the credit for both? Obviously if we only install one cistern to handle both buildings the cistern will be outside the site boundary for one of the buildings. Or do we need to install a cistern for each building so that cistern is located within site boundary for both?

Ruling:

The showers in one of your project buildings can be included in the credit calculations for both buildings, assuming the showers are within 200 yards of the entrance to the adjacent building. To demonstrate achievement for both LEED projects, be sure to demonstrate that the number of showers supports the occupancy for both buildings combined. The same logic applies to features such as a stormwater cistern. If the cistern is constructed to serve the needs of the building/site area in question, it can count towards credit achievement. Essentially it is appropriate to consider your project a campus situation and share infrastructure, as long as each building meets the performance requirements. Applicable Internationally.

Inquiry:

This CIR is in reference to FTE calculations for a multi-floor hotel in a high-density urban setting. FTE calculation for full-time and part-time employees of the hotel can be calculated using actual numbers. Transients as defined by the USGBC are visitors to a building for less than 7 hours. However, this does not always apply to the variable number of guests or the variable amount of time guests will stay in a hotel on a daily basis. The American Hotel & Lodging Association (AH&LA) is the sole national representing body of all sectors in the lodging industry. The AH&LA has lodging occupancy tracked on a weekly basis (research performed by Smith Travel Research). The AH&LA 2006 annual report calculates the year-end lodging occupancy at 63.4%. In a CIR request dated 10/27/2005 (ruling dated 12/9/2005), occupancy for residential projects allows for FTE calculations based on number of bedrooms: 2 regular occupants for a one-bedroom unit, 3 for a two-bedroom unit, and so on. Therefore, since occupancy rates are highly variable for hotels, can FTE be calculated based on the number of rooms x average occupancy/room (e.g. 2) in a hotel multiplied by an average lodging occupancy percent (per the AH&LA) to obtain the transient occupant calculation? For example: 200 units x 2 guests/unit = 400 total guests; 400 guests x 60% (average of the AH&LA information) = 240 calculated transient occupants. This number would then be the transient occupant count added to the calculated FTE of employees for the occupant value for LEED calculations.

Ruling:

Your FTE approach seems reasonable based on the variable transient occupancy of a hotel, and you are encouraged to utilize it. Please note that previous CIRs have ruled that certain transient populations can be excluded from the calculations in determining the number of required bike storage spaces and showers for this credit.

Inquiry:

We have two questions regarding this credit as it applies to our project: 1. Based on several CRIs, including the 9/10/2007, we understand that in principle as long as 90% or more of the total building area complies with the LEED requirement for the shower requirements and 100% of the building occupants are accounted for in the bicycle parking calculations, the credit intent is met and credit will be awarded. This is also supported by the LEED Canada NC 1.0 Application Guide For Core And Shell Buildings And Leased Tenant Spaces. It states that "To achieve LEED Canada NC certification, the base building and owner fit-up tenant spaces must be fit-up to comply with the LEED Canada NC requirements. In addition, sufficient leased tenant space must demonstrate that it has or will comply with the LEED Canada NC requirements so that overall 90% of the total building area complies with the LEED requirements." This 10% exemption recognizes the difficulty in getting multiple tenants to comply with LEED requirements. We see this as a good precedent to seek an exception for the small tenant spaces that occupy less than 10% of the overall area of the project. Our project is a single tenant class A office building which has about 1% of the total GFA leased out to two very small retail units that are not part of the otherwise single tenant building. These small retail units will have their own bathrooms and their occupants are counted in the overall building bicycle parking calculations, but they do not have dedicated showers as this poses a serious security risk for the primary tenant (a Bank). Can you confirm that the above understanding of the exclusions up to 10% of the GFA for the shower component of the credit is consistent with previous CIR rulings and is acceptable in pursuing this credit? 2. The other part of the question deals with locating shower and bicycle storage off site but within 200 yards. Our LEED Project meets the criteria for this as the Head Offices of this Bank is just down the street with gym facilities including showers. What we would like confirmation whether the sizing of the shower facilities and bicycle racks needs to be based on the occupancies of BOTH buildings or just our project that is pursuing LEED certification. The numbers are as follows: Our LEED Project: There are 436 Full Time Equivalent Staff and 119 Visitors. Head Office 200 yards away: Full Time Staff at Head Office is 516 persons. If we were to provide bicycle storage only for our LEED Project we would only need 22 racks for full time staff plus 6 more for visitors = 28 racks total, and 3 showers ( 1 for every 8 racks serving full time staff only) If we were to provide showers and bicycle rack for BOTH facilities, using only use the Full Time Staff numbers from both facilities, the calculation is as follows: 436 at LEED Project + 516 at Head Office = 952 Full Time Staff x 5% = 48 bicycle racks (rounded up) Showers are counted at 1 shower per 8 bicycle racks, therefore 6 showers would be required to serve BOTH building\'s full time staff. Based on this scenario, we understand that accommodating for 48 bicycle racks and 6 showers at Head Office should fulfill the credit intent and requirements, but seems like it is overkill. Previous CIRs indicated that in such cases, visitor transient populations can be omitted from the calculations. We would like to think this is applicable in this case since we would be almost doubling the shower and bicycle rack requirements. Please confirm if we should base our calculations assuming providing racks and showers for BOTH buildings (our LEED Project and Head Office) full time staff only (excluding visitors), or it is enough to provide only 28 racks and 3 showers to serve our LEED project only.

Ruling:

The project team is seeking clarification on two separate issues - firstly, the applicability of the credit requirements for showers relative to the small retail units (representing less than 1% of the GFA), and secondly, the calculation methodology that should be adopted when bicycle racks and showers are being provided in an adjacent building. For the first question, it is acceptable for the retail units to be excluded from the shower requirements given the small floor area of these units. In regard to the second question, the number of bicycle racks and showers must be sufficient to meet the LEED project requirements only, and does not account for the other building\'s occupants. It is however encouraged to provide a sufficient number for all building occupants (irrespective of LEED certification pursuits) where possible. [The following clarification was added 7/1/2012:] Note this LI is only applicable to projects with a nonresidential square footage one percent of gross floor area or less.

Inquiry:

Two of our projects are supermarkets registered under the LEED NCv2.2 rating system. Because of the uniqueness of the grocery retail building type, we utilized strategies from the LEED for Retail Pilot program to help make sense of some of the LEED-NC credits in the retail environment. Case in point, our energy modeler had to utilize the LEED for Retail application guide to model the heavy refrigeration loads of the building because the LEED-NC Reference Guide & ASHRAE 90.1-2004 Appendix G make no accommodation for it. Similarly, the Sustainable Sites 4 group of credits is in many ways does not fit well with the drastically different occupancy of retail from a typical office building. In the specific case of Bicycle Commuting, it is simply not appropriate to provide showers to retail customers and these can cause personnel problems when provided to retail employees. Furthermore, providing carpooling spaces to retail customers does not achieve the intended benefit, as the meaning of carpooling is called into question. The AGR has made great strides in tailoring the LEED-NC rating system to the unique characteristics of retail buildings by allowing multiple compliance approaches to provide an effective means of encouraging alternative transportation. Unfortunately, we had been inadvertently led by the USGBC to believe (and communicated to our clients) that we could utilize the AGR on our LEED-NC projects even during the Retail pilot prior to being fully balloted. We request that the LEED for Retail TAG allow our team to use the SSc4 credits from the AGR on these supermarkets in a manner similar to the way clusters of credits are currently allowed equivalency across already-established LEED rating systems. Specifically, can we would like to utilize the Bicycle Storage & Changing Rooms and Parking Capacity credit interpretations from LEED for Retail in these two LEED NC registered supermarkets.

Ruling:

This CIR is seeking permission to substitute the LEED for Retail credit requirements on a project that is otherwise certifying under LEED-NC. The project has requested permission to substitute the requirements for SSc4.2-Bicycle Storage and Changing Rooms and SSc4.4-Parking Capacity. Per the SSc4.2 CIR ruling of 10/17/2007, the project is allowed to use the credits as outlined in the LEED for Retail-NC rating system as long as the pilot program is underway. Following the full balloting and adoption of the LEED for Retail-NC rating system, the project would be required to switch from the NC 2.2 to the Retail-NC rating system to use the credit requirements.***Update 1/1/13: This LI is non-applicable to versions of LEED other than LEED 2009.

This credit interpretation request is in reference to LEED-EB requirements for a 497 000 s.f.g. Convention Centre located in Quebec City (Canada), winner of the 2006 AIPC Apex Award for the World\'s Best Congress Centre given by the International Association of Congress Centres. The Quebec City Convention Centre (QCCC) has for mission to welcome conferences, meetings and large-scale exhibits by offering an international convention facility. Three (3) user types are indicated for the congress Centre: administrators, organizers and visitors. 1. Most of the administrators (approximately 70 people) carry on their functions from an adjacent building from the convention Centre. Only three employees are working on a daily basis in the centre in period of event. These full-time employees shall be included in calculations. 2. Organizers are exclusively subcontractors. The Centre doesn\'t have any direct employee appointed to events organization. Number of organizers shall be estimated to be included in calculations. 3. Visitors represent the majority of building occupants. Visitors do not qualify as transient occupants because most of them use the Centre for at least one day/event. All events held at the Centre cover a period, in average, of 340 occupation days per years. Some events require the visitors\' presence inside the Centre for a period of more than 8 hours. Some events require the visitors\' presence for less than 8 hours. Number of visitors shall be estimated to be included in calculations. Occupants\' estimation Administrators: The number of three full-time employees will be used in calculations. Visitors: According to administrators\' projections, the number of visitors attending events held in the Centre (short and long period) can be divided on a basis of 8 hours of occupation to estimate an average of occupants/day. The Centre is monitoring the number of entrances/event. The exact number of participants from the two last years\' data would be used to calculate (on an 8 hours basis) the number of daily regular occupants. Organizers: All organizers are subcontracted by the QCCC. The QCCC doesn\'t keep track of many employees from each subcontractor is working inside of the Centre. However, the Centre administrators estimate from their experience the number of organizers/day required to set up and operate an event to 4%, in average, of the total participants attending an event. Are the 2 above estimations acceptable in order to complete calculations/requirements of credit SSc3.2 of LEED-EB V2.0?

Ruling:

The above estimations appear reasonable with the following notes: Bike racks and showers require different occupancy calculations. For showers, occupants should be considered individuals who regularly spend a full working day at the facility. This would seem to imply administrators and organizers (but not visitors) in this instance. Bike racks, however, should include visitors in the occupancy calculation as you have suggested in the \'occupants estimation\' above. Also, please note that it would be unusual for a 500,000 square foot convention center to have a full-time staff of only 3 employees. Please ensure that occupancy calculations include management, staff, food services, and particularly custodial services, (unless those services all fall within the \'organizer\' category as well, in which case you have addressed them already).

Inquiry:

The intent of this credit is to reduce pollution and land development impacts from automobile use. Pacific Garden Mission (PGM), a homeless shelter for homeless men and women in Chicago, is proposing an alternate calculation for the required bicycle storage capacity for this facility. PGM has four types of occupants: Transient-homeless; Program-people, Resident-staff and Commuting-staff. The Transient-homeless are the primary occupants. Averaging about 800 people, they come and go nightly with only what they can carry in bags, suitcases or backpacks. They certainly do not have cars or bicycles to use and/or bring to PGM. They stay temporarily at PGM-not long enough to qualify as residents or to enable them to even consider acquiring a bicycle. Therefore, it does not seem appropriate to include them in the calculating the required amount of bicycle storage. We propose to not require bicycle storage for the Transient-homeless population at the facility. Program-people are homeless people who are enrolled in training/education programs at PGM. The average program person resides 45 days before moving on. These 140 people are not long-term residents but some may have the opportunity to acquire a bicycle during their 45 day stay. Most likely it would be a used bicycle that would be kept outside. We propose to allocate outside bike storage for 5% of the Program-people. (140 x 5% = 7 outside spaces). Resident-staff work and reside at PGM. Of the sixty (60) total staff, forty (40) are Resident-staff that live at the facility and twenty (20) commute. The Resident-staff typically stay for 2 to 3 years and are therefore able to own bicycles. As such, the project team proposes to calculate the amount of bicycle storage for Resident-staff as detailed by the LEED Reference Guide for a residential facility. This means that covered bicycle storage for 15% of these occupants must be provided. (40 x 15% = 6 covered spaces) For Commuting staff, the need for bicycle storage for staff will be calculated as detailed by the LEED Reference Guide for a commercial facility. This means that bicycle storage for 5% of these occupants will be provided, plus separate showering facilities as per the LEED Reference Guide. (20 x 5% = 1 outside space) In summary, the proposed changes are to: 1) Not allocate bicycle storage for the Transient-Homeless population since they do not have, nor is it practical for them to have, bicycles; 2) Allocate outside bicycle racks for 5% of the Program-People. 3) The resulting proposed required amount of bicycle storage and the actual storage in the design are summarized as follows: Occupant Type #Occupants Typical Duration of Stay Type storage % of occupants served # of bikes stored Transient-homeless 800 1-2 days overnight N.A. 0% 0 Program-people 140 45 days overnight Open 5% 7 Resident staff 40 2 to 3 years Covered 15% 6 Commuting staff 20 One 8-hour shift/day Open 5% 1 Type storage # bicycles stored # bicycles stored # extra spaces Proposed Requirement In The Design In the Design Open 8 18 10 Covered 6 7 1 Note that the design does call for a number of extra spaces that could be allocated as needed among the all the various occupants. Please let us know if this alternative method for calculating the requirements of SS Credit 4.2 is acceptable.

Ruling:

The applicant is requesting clarification about how bicycle parking requirements pertain to overnight homeless residents and longer-term homeless residents in a homeless shelter for homeless men and women in Chicago. Given the specific circumstances of this project, the proposed approach of exempting the overnight homeless residents from bicycle parking requirements is appropriate. However, the longer term Program-people must be included under the residential requirement of covered bicycle parking for 15% of occupants, as these occupants reside in the building and bicycle use may be offsetting car, bus or other transit trips. The proposed calculations for resident staff and commuting staff are appropriate. Applicable Internationally.

Inquiry:

We are requesting a ruling about how occupants should be calculated in SSc4.2 for our project, which is a professional hockey arena. A previous CIR Ruling (9/14/2006) established that "Excluding a certain type of transient occupants from the required bicycle stall and shower calculations is permissible per previous v2.1 CIR Rulings dated 6/4/2003 and 8/7/2002. Please include a short narrative indicating the number of visitors who have been excluded from these calculations and an explanation of why this type of visitor cannot reasonably be expected to arrive at this destination on or with a bicycle that would benefit from onsite storage facilities." These CIRs related to projects which were destination resorts and airline terminals. Our project, a professional hockey arena, has similar occupancy concerns that make it impractical to provide bicycle racks for all transient occupants. Because the largest events (hockey games) are held late at night and because many event attendees are coming from far away, it is much more likely for attendees to carpool and use public transit than to ride a bicycle. The project anticipates achieving SSc4.1 (numerous bus lines within 1/4 mile and a rail line within 1/2 mile) and SSc4.3 and 4.4 (preferred parking for carpools and efficient vehicles). In addition, for SSc4.2, the project will be building a new bike path to encourage bicycle use, especially during daytime events. Thus, we have developed ways to address both daytime and nighttime events, as described below: For daytime events, our project team has identified two options to address the intent of SSc4.2 that we would like to get direction from the USGBC on: 1. Provide 100 secure bike racks for 5% of the FTE staff plus 5% of the transient occupants who attend daytime events. Peak occupancy during daytime events is expected to be for tradeshows that occupy the main hockey floor space. For this use, occupancy is expected to be about 2000 people for the peak event time. This figure represents about 300 operation/vendors, 1685 attendees and 15 staff. Thus 100 bike racks represent 5% of this occupancy to satisfy the intent of credit SSc4.2. OR 2. Provide 50 secure bike racks for general-use occupancy and require the Events Operator to set up a secure bike corral for at least 50 additional bike racks for any event that anticipates attendance in excess of 1000 people for its peak occupancy time. Nighttime events will be larger, up to 6000 people (peak concert); but as noted above, late egress will discourage bicycle ridership such that peak use will be less than daytime events. For nighttime events, we feel it is only reasonable to expect attendees to ride a bicycle if they live within 5 miles of the arena. The website CommuterChoice.com notes that the average bicycle commute in the US is about 2 miles, so we feel that this allowance of a 5 mile bicycle commute to the arena at night is an aggressive expectation. Our transportation consultant has estimated that about 7% of attendees live within 5 miles of the arena. Thus, for the maximum event of 6000 people, the number of attendees living within 5 miles of the arena would be 420 people. Staff/vendors at this event would be 315, making a total of 735. The 100 or 50 bike racks that would be provided for the project thus represent respectively 13% and 7% of the nighttime occupants who might be expected to commute by bicycle to the event. Showers will be provided to meet the requirement of 0.5% of FTE staff for all events (both daytime and nighttime). The project team feels that this night-time approach and both the daytime options meet the intent of SSc4.2 for this type of facility. We request that the USGBC either confirm that our approach is valid for both daytime event options and nighttime events, or provide clear guidance on how our assumptions should be modified to meet the intent of SSc4.2.

Ruling:

The CIR is requesting clarification on calculation of occupancy for a large sports arena in order to provide the appropriate number of bicycle racks. The team has provided multiple assumptions and calculation methodologies and is requesting guidance on which approaches should be used. 1. The team has presented assumptions regarding which transient occupants can be expected to use bicycles to reach the event. The team assumes that visitors coming to the site at night are less likely to ride bikes than those coming during the day due to safety concerns, and therefore more there will be a higher demand for bike parking in the day, even though peak occupancy is lower. This is potentially a reasonable assumption, given that the project team provides clear information on the types of day and night uses, the hours of operation, the peak occupancies of each use and other relevant justifying information or data. 2. The team has stated that visitors living within a five mile radius of the site are the most likely to travel by bike, and therefore bikes should be provided for local visitors only. Focusing on local visitors is an acceptable approach for calculating transient occupants but not regular occupants. Additional information would be required to support the use of a 5-mile radius, as well as to support the calculation of the percentage of visitors within this radius. Detailed calculations from the transportation consultant or other relevant data would be required in order to use this approach, which will be evaluated on a case-by-case basis. Reviewers will take into consideration building type and program, location, bicycle network and other variables in evaluating the merits of this approach. 3. The team has presented two strategies for providing bicycle storage—either permanent secure bike parking or valet service for bike storage. Either approach is acceptable. If a valet service is being used, refer to the requirements included in NC v2.2, SSc4.2 CIR ruling 10/24/2007.

LEED Interpretation
Inquiry:

Establishment of baseline FTE for a Transient Facility:This Washington, DC Major League Ballpark experiences a transient population roughly 81 times per year on "event" days only (a ballgame). The project team developed a calculation to determine the number of Full Time Equivalents that would become the baseline for the bicycle racks and showering facilities required. The team originally took the full time building population (250 occupants at 8 hours per day/total person hours per day/260 annual days of occupancy/total person hours per year) and a part-time population count based on the number of fans that would be attending an event in equivalent hours (35,000 avg. game attendance at 4 hours per day/total person hours per day/81 annual days of occupancy/total person hours per year) for a total FTE of 5702 occupants.Bicycle Racks Calculation:With a baseline FTE of 5702, the total number of bike racks required to satisfy the credit requirements are: FTE = 5702 * 5% = 286 bike racks required.Original Solution:In order to support bicycle transportation as a viable means of accessing the Ballpark, the District of Columbia Department of Transportation (DDOT) is donating 286 bicycle storage racks which will be located around the ballpark site, convenient to multiple points of entry (within 200 yards). Secure bicycle storage is provided in the garage for full time employees. The Ballpark team submitted documentation to this effect on July 30, 2007. In addition to 286 racks on site, DDOT will be installing racks on surrounding blocks, however the exact number and location is not determined at this time. The Ballpark team felt this met the intent of the credit by supporting the use of bicycle transportation to and from the Ballpark, however the credit was denied in the design phase review (with request for clarification).Design Phase Review Response:"The LEED Submittal Template has been provided claiming that the project has provided bicycle storage and shower facilities for 5% of the FTE building occupants. For this credit, the peak number of transient occupants should be included in the FTE occupant count. For a ballpark, transient occupants will be at the stadium at the same time, so the peak occupancy should not assume a diversity factor, but should include all guests and staff that are likely to be at a ballpark during a sold-out game.TECHNICAL ADVICE: Please provide revised FTE occupancy calculations that account for transient visitors at peak occupancy. The calculations should include the peak number of transient visitors expected to visit the building at any given time."Revised Calculation:If we add the peak attendance of 41,000 (sold out game) plus 250 FTE, the credit would require 2,064 bicycle storage spaces. According to the Executive Director of the Washington Area Bicyclist Association (WABA), this exceeds the bicycle storage capacity at Amsterdam Central Station and would constitute about a linear mile of bicycles. The WABA has over 7,000 members, yet the Executive Director remarked that providing nearly 300 storage spaces is already probably in excess of need, let alone over 2,000.The Ballpark team also finds 2,064 permanent storage spaces to be excessive for numerous reasons:The LEED Rating System (and this credit) was originally developed to address commercial office buildings. Whether by bicycle, private car or public transit, both FTE and Transient populations typically arrive at buildings of this type individually rather than in groups (unless they are carpooling, which is addressed by another credit). Ball games tend to be social events, primarily attended by groups of people rather than by individuals. The Ballpark project has already been approved for an exemplary performance ID credit under Transportation Management Plan for its plentiful access to public transportation and for not providing public parking.While the Ballpark team does anticipate some individual attendance at games (a portion of which may arrive by bicycle), there is no evidence to support the expectation of anywhere close to 2,000 cycling attendees. Indeed, the San Francisco Giants stadium provides a bicycle valet for 150 bicycles and is only currently storing up to 125 bicycles on game days.The Ballpark team feels providing an excessive amount of permanent storage at this time is contrary to the general underlying environmental intent of the credit. The production of these racks will require the use of materials - both raw and recycled - in addition to the energy that will be used to manufacture and transport the racks. If the San Francisco stadium is any indication, only about 6% of the 2,064 racks would be used.2,064 racks will also require a large amount of land to be set aside for this use, and on a compact urban infill site the Ballpark team does not feel providing racks in large excess of demand constitutes the highest and best use of the land.An alternative solution has been developed, one the Ballpark team feels bridges the gap between providing permanent storage capacity for 2,064 bicycles and our original proposal of 286.Alternative Solution:The Ballpark team proposes to continue with installation of 286 permanent bicycle storage racks and to provide an additional bicycle valet service on game days. This is a more flexible and environmentally sensitive solution to permanent racks, and can be quickly responsive to growing demand.We propose to model our Ballpark bicycle storage capacity both on that of the San Francisco stadium and on the LEED-EB Rating System. In addition to 286 storage spaces, the Ballpark will offer valet service initially for up to 150 bicycles. The WABA has agreed to provide valet service. The Ballpark owners have agreed to offer \'ride-to-the-game day\' promotions that will encourage the use of bicycle transportation through reduced price game tickets on certain dates. At special events such as this, the bicycle valet capacity would be increased beyond 150 to anticipate larger demand.The peak demand will be monitored and valet service capacity will be increased every season that there is an increase in peak usage so that the bicycle storage capacity is maintained at 125% of the peak demand for bicycle parking until a maximum bike storage capacity of 5% of the peak building users is reached (or 2,064).ConclusionThe unique nature of this project type requires a creative approach to this credit. We feel that by committing to providing a combination of permanent storage and a storage service that will enable Ballpark employees and visitors to bicycle to work and games, we are meeting the intent to reduce pollution and landscape development impacts from automobile use.

Ruling:

Given the particular nature of this project, the proposed Alternative Solution does meet the credit intent as it allows for capacity growth based on peak demand. This approach is applicable to stadiums and special event facilities only. Along with required credit documentation, please provide documentation demonstrating an ongoing bicycle valet service program (a signed contract for the service is acceptable) which includes stipulation for increased growth based on demand up to 2,064 bicycles.Please also provide a narrative which details how demand will be monitored and capacity increased over time, along with a description of how and where bicycle storage sufficient to accommodate up to 2,064 bicycles will be provided should there be that level of demand.Note that showers and changing facilities must be made available to all full-time equivalent (FTE) employees.

LEED Interpretation
Inquiry:

We are requesting a ruling upon which occupants shall be included in the bicycle and shower calculations for SSc4.2. A previous CIR Ruling for LEED-NC 2.1 (dated 06/04/03) stated that an international airline terminal could meet the intent of this credit by providing adequate bicycle spaces and changing/showering facilities for only the staff employees if the calculation included all staff and the project maximized alternative transportation opportunities for transient occupants. Our project, a large destination resort, has similar occupancy conditions to the above-referenced CIR Ruling that make it impractical to provide bicycle racks for the transient occupants. Our project contains the following uses: hotels, condominiums, retail shops, conference center, theater, gaming, and restaurants. As a result, we propose to identify three types of occupants in this project - employees, condominium residents, and transient guests. Our transient guests travel from around the country and the world and arrive via the airport or long distance car & bus trips. These guests are served by a variety of alternative transportation services such as monorails, city buses, a tourist trolley, and hotel shuttle buses. Consistent with the resort\'s commitment to integrating environmental sustainability into the project, we will be making a substantial investment in supporting bicycling. We are planning to provide over 300 bicycle spaces and the associated number of showers, based on our employee counts. The impact opportunity is substantial. Since the commuting characteristics of this project are similar to the airport terminal situation described in the previous CIR, with the addition of a residential component, please confirm that we can achieve this credit by providing bicycle spaces for 5% of peak on-site employees, showers for 0.5% of peak on-site employees and bicycle spaces for 15% of condominium residents.

Ruling:

Excluding a certain type of transient occupants from the required bicycle stall and shower calculations is permissible per previous v2.1 CIR Rulings dated 6/4/2003 and 8/7/2002. Please include a short narrative indicating the number of visitors who have been excluded from these calculations and an explanation of why this type of visitor cannot reasonably be expected to arrive at this destination on or with a bicycle that would benefit from on site storage facilities. It is not acceptable to automatically exclude all transient visitors from these calculations as it is reasonable to expect that some of the visitors to the retail shops, conference center, theater, and gaming facilities could potentially arrive on a bicycle, therefore please be certain to include these areas, when appropriate, in the bicycle stall calculations. The proposed strategy to provide bicycle stalls for 15% of condominium residents is consistent with credit requirements for residential buildings. Applicable Internationally.

Inquiry:

We are requesting approval of an alternate compliance path with regards to the quantity of showers required to comply with Sustainable Sites Credit 4.2 in the LEED NCv2.2 rating system. Our project, located in Cairo, Egypt, provides areas within the building for prayer and ablution areas adjacent to it used for ritual cleansing before prayer time. Each ablution area, one each for males and females, will have four sinks that are actually shower-like faucets on a wall above a trough for a total of eight sinks. We will send a photo example separately. There are no walls or enclosures around each of the sinks, although there are separate ablution areas for men and women. Users remain robed while using the sinks, except for socks, shoes and jackets. Users will typically roll up their sleeves and using a washcloth wash their arms, armpits, face, hair, feet and lower legs. While these ablution areas are used for religious practice, it is common and socially acceptable to use them for general washing as well. Furthermore, social norms do not dictate full daily washings that are typical of American culture, making "sponge" bathing a more common practice for personal hygiene for the majority of the population. We are proposing that each bathing fixture in each ablution area be counted as an individual shower, in our case eight in total. In order to fulfill the need of all occupants of the building, four regular showers, two for each gender, will also be provided in the building for occupants that wish to use a full shower and changing facility. Our building has an FTE of 1080, which requires 5.4 showers, or 3 for each gender. We believe that access to the 4 showers and 8 ablution sinks meets the intent of the credit while also being more appropriate for the social customs of the culture. Is this approach acceptable?

Ruling:

The project is located in Egypt and is seeking confirmation on whether the use of ablution sinks can be considered towards achievement of this credit. Based on the specific local religious and social customs, the use of ablution sinks can be deemed comparable to the use of showers, and can be included in the total number of showers required for credit compliance. However, in cases like this, at a minimum, 50% of the required number of showers must be provided by full showers/changing facilities, to ensure that all occupant needs are adequately met. The project team should include justification for this alternative approach in the LEED submission, clearly demonstrating that the majority of the building occupants adhere to these religious and social customs, and the associated use of the ablution sinks.

Inquiry:

We use Case 2 for compliance. According to our calculation for this credit, we think that we need to provide 13 showers. Question 1: How are the showers required to be split between male and female, if not unisex? We split 50:50. Question 2: The building has 617,149 sqft. This number includes all floors, including two roof floors with technical rooms and the lower levels including one floor with only technical spaces. To determine default occupancy count, we divided the building\'s gross square feet by 250 (general office). Do we need to apply this rate to the whole building or can we first subtract the square footage of main technical rooms and/or of complete technical floors (64,600 sqft)? Question 3: Our building is a mixed use building with one multipurpose room and foyer on a lower level, and a small caf

Ruling:

The project is seeking clarification for how to determine the anticipated occupancy of their project for the purposes of Sustainable Sites credit 4.2.The CS Appendix 1 Default Occupancy Counts is required to be used for the project types listed for any CS project that does not know actually occupancy numbers. The numbers are based on average gross square foot per occupant of buildings of that type and include support spaces such as lobbies, mechanical room, storage and other non-rentable spaces. Large, unoccupied areas that are not typical of most projects, such as below grade parking garages, may be excluded from the gross square footage for the purpose of the occupancy calculations. However, projects which exclude any portion of the gross square footage must provide a supplemental narrative stating the portion of the project and providing an explanation on why this area is not typical for most projects of that type, and why the area should be excluded from the calculation. For mixed use projects, the project should first determine the percentage of the building that is each use. Then the gross building area should be divided up based on those percentages, this will allocate common areas, such as foyers and mechanical spaces, proportionally between the different uses. The project should note that the Appendix 3 LEED-CS Project Scope Checklist, which is required to be submitted for certification and precertification, can assist with this calculation. For building types that are not covered under the Appendix 1 defaults, the project must determine the typical gross square foot per occupant for the building type to use. For example, this can be done through case study of similar type projects, discussions with tenants, or research of publish industry standards. It may also be noted, that the LEED 2009 Reference Guide for Green Building Design and Construction Appendix has an expanded table with additionally occupancies. This table is not required to be used by LEED-CS 2.0 projects, however may be used in lieu of project determined defaults if the project chooses. For restaurants, the default is for FTE is 435 gross square foot per occupant and 95 gross square foot per occupant for transient visitors. There is a known template error for this credit. The calculations provided have been done correctly, and the project should attach the supplemental calculations as shown above for certification. For projects that have an odd number of minimum required showers that wish to divide them between genders, such as the 13 total or 6.5 per gender for this project, the project can either provide an additional shower, 14 total or 7 per gender, therefore meeting the minimum requirement for each gender or can provide a unisex shower that would be usable by either gender.

Inquiry:

Under LEED-CS v2.0, Case 2, for projects with a total gross square footage greater than 300,000 square feet, provide secure bicycle storage for 3% of the occupants for up to 300,000 square feet, then an additional 5% for the occupants for the space over 300,000 square feet. This calculation is done for each use of the building in mixed-use projects. Projects must also provide shower and changing facilities in the building for 5% of Full-Time Equivalent (FTE) occupants. Our project consists of 900,000 square feet of office space and 60,000 square feet of retail space. Since the tenants are unknown, occupancy has been calculated using Appendix 1 - Default Occupancy Counts in the LEED-CS v2.0 Reference Guide. Our calculations project 3,600 FTE for office space and 109 FTE for retail space. This requires a total of 210 secure bicycle storage units which will be included in the Core and Shell project. However, the building tenants are unknown. We do not feel it is appropriate to provide shower facilities for an estimated 3,709 occupants as part of the Core and Shell project. Instead of placing 186 shower facilities in a central location, we propose recommending the shower requirement in the tenant guidelines, requiring that each tenant provide shower and changing facilities for 5% of their employees. This will allow the tenants more flexibility to meet spatial and functional requirements, including the location and number of showers. The design team and the owner feel that the intent of the credit is met by this solution. Please rule on whether this approach is acceptable.

Ruling:

As noted in the LEED-CS Rating System introduction (page 8), an owner can choose to make specific lease requirements a part of the tenant negotiations, and if these requirements meet the criteria of a particular credit in the LEED-CS Rating System, the LEED-CS project itself may be able to achieve this credit even if the work is not a part of the core and shell design and construction. The project would need to be able to demonstrate that the lease language requires (rather than recommends) that the build-out of the respective tenant spaces includes sufficient shower and changing facilities for 0.5% (not 5% as noted above) of the Full-Time Equivalent (FTE) occupants. If the owner elects to provide these for the tenants, they will need to provide 19 showers for the anticipated FTE number of 3,709 occupants. It should also be clarified that the number of bicycle storage units has also been miscalculated, and should be based on the credit requirements of 3% of the occupants for up to 300,000 square feet, then an additional 0.5% (not 5%) for the occupants for the space over 300,000 square feet.

Inquiry:

We are requesting a ruling on an alternative approach to calculating required bicycle storage for SS Credit 4.2 for a professional hockey arena. Occupancy for the facility is expected to be as follows: FTE: 115 Peak event staff: 700 Peak spectators: 18,500 Peak players: 25 Total: 19,340 Bicycle storage to serve all guests and staff who are likely to be at the arena during a sold-out game, would amount to 967 storage spaces if the credit requirements were followed as written. However, for reasons similar to those presented in the Credit Interpretation Requests dated 9/12/2007 and 10/5/2007 the project team feels that it is impractical to impose the same bicycle storage rules for this facility as for office buildings, namely: - Transient occupants tend to attend sporting and entertainment events in groups rather than as individuals. - This project has ample public transportation within 1/4 mile of the site. - The largest events occur in the evenings in the winter, times during which cycling is not ideal for safety and comfort reasons. - Similar facilities, such as the SF Giants described in the 9/12/2007 CIR, have demonstrated that current demand for bicycle storage is significantly lower than what SS Credit 4.2 requires. - The land required to provide permanent bicycle storage that has little likelihood of being used is not an ideal usage of the site. The project team proposes two ways of providing bicycle storage quantity that will adequately serve the realistically expected current demand for this facility while allowing for capacity growth based on peak demand. 1. To establish the current demand for transient occupant bicycle storage, statistics from a local non-profit cyclist organization whose mission is "to establish [a] city that is increasingly safe, accessible, and friendly to bicycle transportation" will be used. This organization states that the current rate of commuting by cyclists to the arena neighborhood is 0.8%. Applying this statistic to the peak occupancy stated above, 154 bicycle storage spaces would be needed for events. To accommodate 125% of this estimated demand, a total of 194 bicycle storage spaces would be provided using permanent and/or valet bicycle storage. Over time, peak demand will be monitored such that bicycle storage provided always exceeds demand by 25% until the maximum bike storage capacity of 5% of peak building users (or 967) is met. OR 2. To establish the current demand for bicycle, the team management will survey staff and season ticket holders to determine: a. The number (and percentage) that currently travels to events via bicycle b. The number (and percentage) who would consider traveling to events via bicycle if secure storage were provided at the arena Based on the survey results, enough permanent and/or valet bicycle storage will be provided to accommodate 125% of current demand. Each season, peak demand will be monitored such that bicycle storage provided always exceeds demand by 25% until the maximum bike storage capacity of 5% of peak building users (or 967) is met. For both approaches above, shower/changing facilities will be made available for 0.5% of all FTE occupants. If a valet service is used it will be implemented considering the requirements in the CIR ruling dated 10/24/2007.

Ruling:

The project team is requesting guidance on two alternative approaches to calculating the number of bi-cycles to be accommodated with secure bicycle storage for a professional hockey arena. The project has proposed 2 approaches, both resulting in the provision of 125% of the current estimated bicycle parking and storage needs, with regular monitoring to ensure available bicycle parking and storage exceeds demand by 25% until the credit requirement— providing bicycle storage for 5% of the building occupants—has been met. Approach 1 is based on the based on statistics gathered from a local biking advocacy organization, whereas Approach 2 is based on a survey of staff and season ticket holders. Either strategy is acceptable, as long as documentation of the process includes detailed calculations, and a description of how the current bike capacity was determined. The project team must also show how the bicycle storage will be monitored and demonstrate the capacity for future expansion exists, should it be needed, as stated in LEED NC 2.2, SSc4.2 CIR ruling 10/24/2007. The alternate strategy outlined is acceptable for large special events facilities only, because of the particular nature of these projects.

Inquiry:

Our firm is currently working on a project designated as a port of entry from Mexico to the US. We are requesting a clarification on how occupants should be calculated in SSc4.2. CIR Ruling (9/14/2006) established that "Excluding a certain type of transient occupant from the required bicycle stall and shower calculations is permissible per previous v2.1 CIR Rulings dated 6/4/2003 and 8/7/2002. Please include a short narrative indicating the number of visitors who have been excluded from these calculations and an explanation of why this type of visitor cannot reasonably be expected to arrive at this destination on or with a bicycle that would benefit from onsite storage facilities." These CIRs related to projects which were destination resorts and airline terminals. Our project, a US Port of Entry, has similar occupancy concerns that make it impractical to provide bicycle racks for all transient occupants. The vast majority of transients are typically crossing from Mexico into the US and are only passing through the facility. They consist of pedestrians or transients entering via automobile or motorcycles. If transients are commuting via bicycle they would typically not be spending time at the facility but merely passing through. This project anticipates achieving SSc4.1 (numerous bus lines within 1/4 mile and a rail line within 1/2 mile) and SSc4.3 and 4.4 (preferred parking for carpools and efficient vehicles). In addition to the previous credits this project will also obtain credit for SSc4.2. This project has 120 FTE and 22,720 transients. Using the above CIR Ruling, the occupant calculation would require 1,142 Bicycle Racks. However, in light of the fact that we believe the majority of the transients would simply be "passing through" this calculation seems excessive for this project. Our project team has identified the following option to address the intent of SSc4.2 and we would like to get direction from the USGBC on the following option: Provide bicycle storage for 5% FTE Showers will be provided to meet the requirement of 0.5% of FTE staff. The project team feels that this approach meets the intent of SSc4.2 for this type of facility. We respectfully request that the USGBC confirm that our approach is valid or provide clear guidance on how our assumptions should be modified to meet the intent of SSc4.2.

Ruling:

Providing bicycle storage for 5% of FTE and showers for 0.5% of FTE is an appropriate approach given the project circumstances and that other transportation credits are being pursued to accommodate the FTE and transient occupants. The exclusion of occupants who are passing through only to cross the border is in line with previous CIR rulings. When submitting the credit please include a short narrative indicating the number of visitors who have been excluded from these calculations and an explanation of why this type of visitor cannot reasonably be expected to arrive at this destination on or with a bicycle that would benefit from onsite storage facilities.

Ruling:

Per the LEED NC v2.1 SSc4.2 ruling dated 12/9/2005, occupancy should be calculated using the number of bedrooms in the case of residential projects. Project teams should provide a narrative with calculations demonstrating how the total number of residential FTE occupants was calculated including indication of number of units, size of units (e.g. studio, one bedroom, two bedroom, etc.), and assumptions as to number of occupants per each size of unit.

Inquiry:

It appears that the LEED criteria may be developed for a more generic office situation and our college campus operates very differently. There are several extenuating factors. Unlike most similar higher education institutions, Colorado College has maintained a relatively constant student population as mandated in the school\'s educational charter. Therefore, an additional building does not imply more students although may indicate additional educators and support staff. Colorado College is a small residential campus requiring ~75% of the students to live in campus housing (all students except seniors must live on campus), which is on contiguous property and within easy walking distance, ~ 1/4 mile. A portion of the professors are also visitors, living in campus housing during their instructional Block (this reduction has not been entered into the calculation). The use of automobiles to attend daily classes is minimal, due to the very short distance. Colorado College operates educationally under the "Block Plan" where only one class is taken at a time for a three and one half week duration in a dedicated Classroom; generally, there is only one class per Classroom per day. The actual usage of the space as compared to the FTE (full time equivalent) students is realistically less than one when considering the primary classroom session generally is in the morning (this reduction has not been entered into the calculation). A maximum of 25 students is allowed per class, so this number is used in the following calculations but the actual students per class will average less (this reduction has not been entered into the calculation). The following numbers are based on actual Classroom and Office room counts for the Tutt Science Center. --437 students count or ~110 adjusted students count when only 25% arrive from the surrounding community --35 professors and support staff when assuming 100% arrive from the surrounding community --437 + 35 equal 472 total building population --110 + 35 equal 145 adjusted total building population Our question is, can we use the 472 people as our total building population, while using the "adjusted" or "commuter" population for determining showering facilities and parking requirements? This would mean that 472 would be used to determine bike rack needs, which seems appropriate as the on-campus students may also ride bikes for a short distance, while 145 would be used as the building population when determining showering facilities, number of parking spaces, and also the number of alternative refueling stations. For example, using the total population for the bicycle storage capacity would give .05 x 472 equals ~24. Considering the short travel distance for most, shower usage should be minimal and the 145 adjusted building population seems realistic. The resulting count of .05 x 145 / 8 equal ~ 1 shower should be a more accurate appraisal of the potential use.

Ruling:

Showers Per previous inquiry, 0153-SSc42-081701, the LEED Steering Committee has ruled: "Although, transients are required to calculate the bike storage capacity, they shall not be required to be included in the occupant count for calculating the number of showers/changing areas. Transients are defined as visitors to the building for less than 7 hours." Therefore, providing showers based on full time staff or staff FTE will meet the requirements of this credit. Parking If the campus master plan is designed such that 75% of students do not drive to class, and essentially have parking already provided for them adjacent to their housing, their parking needs are already met. The remaining 25% of students and 100% of staff can be used as the \'occupancy\' to calculate required parking and alternative fueling stations. Applicable Internationally.

Inquiry:

This is an inquiry about the calculation of the FTE in relation to our project in Zurich, Switzerland. In the LEED Reference Guide on page 53 the calculation of the FTE is based on a 8-hour working day. That means that an 8-hour occupant has an FTE value of 1.0. The standard working day in Switzerland contains 8.5 hours of work.In a FTE calculation on the basis that is provided in the LEED Reference Guide the normal working day of one single person would have the FTE value of 1.0625. As a consequence of the, in case of 1000 people fulltime staff this FTE calculation would have additional number of 63 FTE in comparion to an FTE value of 1.0.Is it possible to calculate the FTE value for this project with an 8.5 instead of 8 hour day, so that we would have the FTE value of 1.0 for a standard 8.5 hour-working day?

Ruling:

The project team has inquired if projects in Switzerland may use 8.5-hours as their working day instead of 8-hours as in the US. Each full-time employee based on Swiss and US labor laws works an 8.5-hour day, which includes a half-hour unpaid lunch break and two 15-minute paid breaks. In order to maintain the baseline for projects everywhere when calculating FTE occupancy, all Swiss projects, including those industries that have an overtime work culture for full-time employees, should still use the 8.0-hour work day in their FTE calculations.

Inquiry:

There are a number of credit inquiries that relate to the shower requirements at college or university campuses, and as a result, the USGBC has expanded the proximity of changing/shower facilities to the project site from being required on the project site, to being required within 100 yards of the building, to the current standard of being required within 200 yards of the building. This credit inquiry seeks to have Sustainable Sites Credit 4.2 awarded by demonstrating that the intent of the credit is being fully achieved even if the specific distance limit is not. Our project is the renovation of the S.T. Dana Building Renovation, home of the School of Natural Resources & Environment at the University of Michigan, Ann Arbor. Dana is located in the central campus area facing onto the University\'s main quadrangle, know as the Diag. This area of the campus is served by a very large recreational and athletic facility, The Central Campus Recreational Building (CCRB). As an athletic facility, the CCRB provides a substantial number of locker rooms and showers for use by faculty, staff and students on the Central Campus. The CCRB is located roughly 300 yards from the Dana Building. It is easily within a 5 minute walk or a quarter mile of the building, which is the maximum distance LEED allows for walking to a building from public transit. This arrangement currently serves the biking population at the Dana Building with success as demonstrated by the transit survey conducted during the LEED project implementation. A transit survey conducted in April 2002 determined that the current biking population of the Dana Building exceeds the minimum of 5% required for this credit by 22%. - Number of respondents: 171 or 41% of the peak occupant load. (21 faculty; 39 staff; 111 students) - Number of respondents who bike from home to campus: 47 or 27%. Without showers in the building, this exceeds the LEED target by 22%. - Number of respondents who use their bikes to travel around campus during the day: 32. - The survey asked "if you had access to showers, would you be more likely to commute to school/work by bicycle or foot?" 124 or 72% said No. The transit study further determined that the average commute to campus is 6.1 miles and the average commute during the day around campus is 1.2 miles. The peak load occurs during the academic school year, September through May. The climate of Ann Arbor, Michigan, is such that showering after relatively short bike commutes is not necessary, like it might be in a southern and hot, humid campus. The minimum required number of bicycle racks is met within the LEED project boundary; numerous additional racks are provided within 200 yards of the building. The transit survey clearly demonstrates that the intent of this credit has been met at the Dana Building, even though the specific distance requirements are not met. Would this credit be awarded on these grounds? We also request confirmation that our peak occupant load and non-transient occupant load calculations are appropriate. They are as follows. 53 Staff (8 hr/day) = 53 Non-Transients and 53 FTE Occupants (peak load) 57 Faculty (8 hr/day) = 57 Non-Transients and 57 FTE Occupants (peak load) 81 PhD Students (6 hr/day) = 0 Non-Transients and 61 FTE Occupants (peak load) 185 Master (Except LA) Students (4 hr/day) = 0 Non-Transients and 93 FTE Occupants (peak load) 235 Undergraduate Students (2 hr/day) = 0 Non-Transients and 59 FTE Occupants (peak load) 60 Master of Landscape Architecture Students (8 hr/day) = 60 Non-Transients and 60 FTE Occupants (peak load) 29 LS&A (4th Floor) (8 hr/day)= 29 Non-Transients and 29 FTE Occupants (peak load) 700 Total = 199 Non-Transients and 411 FTE Occupants (peak load) Based on 411 FTE Occupants (peak load), secure slots are needed for 21 bicycles (5% min). Based on 199 Non-Transients, two showers are needed.

Ruling:

The transit survey provides clear evidence that there is a sizable bicycling community at the campus, and sufficient bicycle racks have been provided for these cyclists. However, based on the credit requirements and previous CIRs on this issue, the showers that are located 300 yards from the project unfortunately cannot be used to capture this point. Your calculation methodology used to determine the number of FTE building occupants and non-transient occupants is acceptable and consistent with guidelines provided by previous CIRs for this, including the ruling dated 8/7/2002.

Inquiry:

This CIR is in reference to FTE calculations for a multi-floor hotel in a high-density urban setting. FTE calculation for full-time and part-time employees of the hotel can be calculated using actual numbers. Transients as defined by the USGBC are visitors to a building for less than 7 hours. However, this does not always apply to the variable number of guests or the variable amount of time guests will stay in a hotel on a daily basis. The American Hotel & Lodging Association (AH&LA) is the sole national representing body of all sectors in the lodging industry. The AH&LA has lodging occupancy tracked on a weekly basis (research performed by Smith Travel Research). The AH&LA 2006 annual report calculates the year-end lodging occupancy at 63.4%. In a CIR request dated 10/27/2005 (ruling dated 12/9/2005), occupancy for residential projects allows for FTE calculations based on number of bedrooms: 2 regular occupants for a one-bedroom unit, 3 for a two-bedroom unit, and so on. Therefore, since occupancy rates are highly variable for hotels, can FTE be calculated based on the number of rooms x average occupancy/room (e.g. 2) in a hotel multiplied by an average lodging occupancy percent (per the AH&LA) to obtain the transient occupant calculation? For example: 200 units x 2 guests/unit = 400 total guests; 400 guests x 60% (average of the AH&LA information) = 240 calculated transient occupants. This number would then be the transient occupant count added to the calculated FTE of employees for the occupant value for LEED calculations.

Ruling:

Your FTE approach seems reasonable based on the variable transient occupancy of a hotel, and you are encouraged to utilize it. Please note that previous CIRs have ruled that certain transient populations can be excluded from the calculations in determining the number of required bike storage spaces and showers for this credit.

Inquiry:

We are seeking clarification on the requirements for mixed-use residential projects seeking SSc4.2 - Alternative Transportation, Bicycle Storage and Changing Rooms. The clarification is sought for both LEED-NC 2.1 and 2.2 projects. A recent certification review ruling indicated that changing/shower facilities must be provided for the mixed-use residential building concierge and maintenance staff serving the residential portion of the project. We believe that the language in the reference guide and existing CIR rulings make it clear that it is not necessary. There is no specific reference standard for mixed-use residential buildings. All such projects have been instructed to use LEED-NC. The requirements for mixed-use residential buildings are the same in both LEED-NC Version 2.1 and 2.2. In both, it says: "For residential buildings, provide covered storage facilities for 15% or more of the building occupants in lieu of changing/shower facilities." Therefore, the Reference Guide is clear that all residential buildings do not need to provide showers/changing rooms for the building staff and must instead provide covered bike storage for 15% of the building occupants. For mixed-use buildings with unfinished tenant spaces, CIRs have established that a project team must provide a tenant improvement manual with guidance on how to integrate green strategies into their build-outs and information on pursuing LEED-CI certification. A CIR ruling from 4/4/2005, written specifically for SSc4.4, goes further to clarify: "If the mixed-use building is less than 10% commercial square feet, the entire building can be considered residential and adhere to the residential requirements. Otherwise, the commercial component is to adhere to the commercial requirements, while the residential component is to adhere to the residential requirements." The CIR ruling provides two important clarifications on the shower/changing facility issue. First, if a mixed-use building square footage is more than 90% residential square feet, the ruling indicates that a project team is not required to provide showers/changing facilities in the building as per the credit requirements listed above. Second, if the residential square footage of the mixed-use building is less than 90% of the total building square footage, then showers/changing facilities must be provided for the commercial portion of the building, and "the residential component is to adhere to the residential requirements." Since the concierge and maintenance staff are part of the "residential component", the project team is still not required to provide shower/changing facilities for them. As supported by the CIR, it should be left up to the discretion of the project team if a shower/changing facility for the residential building staff is warranted. Based on the SSc4.2 credit language and the excerpts from the CIR Ruling from 4/4/2005 as explained above, it is clear that a project team is not required to provide a shower for the concierge and maintenance staff in a mixed-use project. If the USGBC wishes to ensure that shower/changing facilities are in fact provided for the building concierge and maintenance staff in mixed-use projects, an addenda revising the credit language for residential buildings is necessary since the Reference Guide currently establishes that for residential buildings, additional bike storage must be provided "in lieu of changing/shower facilities." If the USGBC does issue an addenda revising the credit language for residential buildings, we respectfully request current residential projects registered under LEED-NC 2.1 and 2.2 shall not be retroactively penalized or excluded from achieving the credit provided they meet the existing Reference Guide requirements. It is a good idea to provide the shower/changing facility for the building staff where practical. Any opportunity to provide incentive for use of alternative means of transportation will make a positive contribution towards our collective future. However, it is extreme to disqualify a project from receiving credit because a shower was not provided for as few as three of the building occupants even though the project met the stated requirements and facilitated bicycle riding for hundreds of occupants.

Ruling:

The project is seeking clarification regarding the requirements of SSc4.2 for mixed-use projects. While showers/changing rooms are not required for building staff in a residential building (or the residential portion of a mixed-use building), building staff must be counted as "occupants" when determining the number of bike parking spaces provided in these buildings.

Our project is a 14 story residential building located in MD. Of the building is 152,740 sf with 150,340 sf of residential and 2,400 sf of ground floor retail. The main building occupants will be the 343 residents. The retail space, which for this project\'s purposes is core and shell space, will be occupied by an estimated 5 retail employees, and 19 retail transients.Our question is in regard to the shower requirement of SSc4.2. Given that the retail space comprises only 1.5% of the total floor area of the project, and will be served by only 5 employees, we propose that the project not be required to provide showers and changing facilities for the retail employees. The project will provide bike racks for the residents (343 residents x 15% = 52 bikes), as well as retail employees and retail transients (24 retail employees/transients x 5% = 2 bikes).To support this proposal, we draw on a previous CIR Ruling dated 4/4/2005 which stated that, "If the mixed-use building is less than 10% commercial square feet, the entire building can be considered residential and adhere to the residential requirements."

Ruling:

The Project Team is inquiring whether the shower and changing facility requirements of SSc4.2 can be exempt for the retail area of a mixed use building where the retail area comprises approximately 1.6% of the total building area. For guidance on this issue, the project should refer to LI 10209 which describes how mixed-use projects with a nonresidential square footage of less than 10% and no greater than 5,000 square feet can document credit compliance. Regarding the use of Retail Supplement compliance paths, since rating systems are comprehensive, substituting the Retail Supplement\'s credit requirements for parts of a building project is granted on a case-by-case basis. Given the allowance provided by LI XXXX, it would not be an appropriate to allow additional approaches to documenting credit achievement.

Our project is a Senior Assisted Living Facility registered under the LEED NC 2.2 rating system. In addition to the residential component it includes a restaurant, shop and dining room and will be staffed 24 hours a day with a maximum of 22 staff FTE occupants per shift. We are requesting a ruling excluding the requirement to provide covered bike racks for the residential occupants, whom are unable to bike due to physical limitations and/or health problems. Due to the specific characteristics of the residential population, the project team feels that it is impractical to provide covered bike storage for 15% of the residents, as calculated for SSc4.2 Alternative Transportation, Bike Storage and Changing Rooms. Previous CIR rulings dated 6/4/2003 and 9/14/2006 set a precedence to exclude certain populations from the bicycle storage requirements based upon the practicality of that population to take advantage of the bicycle storage. LEED for Schools also addresses the issue of physical inability and/or safety by limiting the bike rack requirement to students above third grade. To meet the intent of this credit we are proposing that we satisfy the requirements to serve the employees of the project and provide bicycle storage for 5% of the FTE and showers for 0.5% of the FTE and exclude the residential population from the calculation for bicycle storage.

Ruling:

The CIR is requesting that their project be exempted from the requirement for covered bicycle racks for 15% of residents. This request is based on the physical limitations of the residents at this senior assisted living facility and the assumption that they will not be riding bicycles with any regularity. The project has proposed to meet the credit by providing bicycle racks for 5% of the staff FTE, and showers for .5% of the staff FTE, with the residents entirely excluded from the calculations. Based on previous CIRs, especially the ruling dated 12/2/07 under SSc4.4, physically incapacitated residents can be excluded from credit calculations determining bicycle racks. However, in order for the credit requirements to be satisfied, the bicycle racks must be sized to accommodate 5% of both the FTE staff, and the peak transient occupancy including visitors. The proposal to size the showers for 0.5% of the FTE staff is appropriate for credit compliance. Please note that employee shower facilities must be separate from resident shower facilities.

Our building is located on a 1,275-acre university campus among 79 buildings with dozens more in the planning stages. The university has 1,065 support staff, 750 faculty (or 1,435 FTE) and 23,464 peak-period transient students/visitors. Adequate bicycle storage can be easily provided for each building, but providing showers and changing rooms is our challenge. Based on the number of FTE\'s, eight showers would need to be distributed among each of the 79 buildings (see related AGMBC notes). The 200-yard distance maximum would not be possible to maintain for the eight showers required (based on 1,435 FTE\'s) distributed in zones among 79 buildings and therefore the number needed to comply with the requirement for each building would significantly increase by a factor of four times or more. This is not a feasible strategy for the university and also not a good use of resources. However, there are two centrally located facilities on campus with showers to which staff and faculty have unlimited access. The Indoor Recreation Facility has 12 shower heads in 4 areas and the Field House has 143 shower heads in 9 areas. These facilities are linked together with 5 free bus/shuttle lines that operate in 7 to 8 minute intervals between the hours of 7 am and 7 pm. This strategy is analogous to the compliance path for credit EAc4.1 Alternative Transportation: Public Transportation Access, which allows the use of shuttles to connect to primary bus and rail systems. Please confirm that the use of centrally located showers accessible by shuttles is an acceptable alternative to the 200-yard maximum.

Ruling:

The project is requesting that showers farther than 200 yards from the building entrance be acceptable because of the free campus shuttle service available. This is not an acceptable alternative compliance path. In order to make bicycle commuting a viable and attractive option for building occupants the showers must be within 200 yards of the building entrance.

Our project is a dormitory village on a university setting in Phoenix, Arizona. We intend to provide the residents and staff with more than the requisite number of bike racks in fully-covered, secure and easily-accessible locations. Our question pertains to the definition of covered. It is typical in the Southwest to provide protection from the elements with vegetation. We intend to plant mesquite trees, which have a canopy of 25\'-35\', and will completely cover the bike rack area to provide shelter. Is this an acceptable approach to meet the requirements of this credit?

Ruling:

Consistent with CIR ruling dated 5/9/2005, this approach will not meet the requirements of SSc4.2. It is not clear how long it will take for the mesquite trees mentioned to provide a large enough canopy to provide cover for the bike racks. Using trees as cover for bike storage does not ensure that bicycles will not be exposed to the elements. Covered storage areas protect bicycles from sun and rain, providing more of an incentive for their use in lieu of automobiles. Applicable Internationally.

Under LEED NCv2.2, projects must provide adequate bike racks to serve 5% or more of all commercial and retail building users at peak periods of occupancy and shower and changing facilities for 0.5% of Full-Time Equivalent (FTE) occupants. The credit also requires residential projects to provide 15% of residents with covered bike storage. Our project is a mixed use hotel, residential, retail and office building in New York City. We propose to provide: - Bike racks for at least 5% of the hotel and retail employees, retail customers and office tenants - Showers and changing facilities for at least 0.5% of the hotel and retail staff and office occupant FTE - Covered bike storage for at least 15% of residents - Hotel guests with information about where they can rent a bike for daily use We request exemption of the hotel guests from the onsite bike storage requirement as we do not believe they will bring bikes and it would be cost prohibitive to provide enough bike storage to serve 0.5% of them. The USGBC has previously ruled (SSc4.2 ruling dated 06/04/03) that an international airline terminal can meet the intent of this credit by providing bike racks, showers and changing facilities for the FTE staff occupancy exclusively, provided alternative transportation opportunities are maximized for transient occupants. In addition this would be extremely cost prohibitive based on the construction and real estate in New York City. Our project is located on 42nd Street, very near Times Square in midtown Manhattan. The primary modes of transportation around this busy retail, theatre and residential area are walking and subways. The project itself includes a new subway station that will lead pedestrians to 12 subway lines. The City\'s major bus terminal (Port Authority) is a block away from the project. The City\'s two major train stations are within walking distance, but hotel guests can also catch a pedicab, bus or subway from the project to reach them. We do not believe personal bicycles are a likely means of transportation for hotel guests (especially from the airport with luggage) to our project, and guests will have every means of reaching the hotel by public transportation. Out of town guests will be able to reach the project by subway, train or bus from all the major New Jersey and New York airports.

Ruling:

The project team is pursuing LEED- NCv2.2 SSc4.2 and is requesting an exemption for hotel guests from the onsite bike storage requirement. Per previous CIR ruling (NCv2.1 SSc4.2 ruling dated 09/14/06), the proposed approach to exclude hotel guests from onsite bike storage requirements is appropriate given the proximity of the project to mass transit and the explanation provided. When submitting this credit, the narrative should include the number of people that are excluded from SSc4.2 occupancy counts and why this type of visitor cannot reasonably be expected to arrive at this destination on or with a bicycle. The submittal should also state how guests with bicycles will be accommodated. See the LEED NCv2.1 SSc4.2 CIR ruling dated 5/13/2007 for information on calculating hotel occupancy. As you correctly mention, other transient occupants such as retail customers should be included in occupancy counts, along with all the FTEs (all building staff and office tenants) and building residents.

My question isn\'t necessarily about Credit 4.2. It\'s mostly about the definition of the site boundary. I have reviewed previous CIRs and from that I learned the site definition needs to be consistent with all credits.My project is two adjacent buildings which will be certified separately; their construction schedules are the same.Here\'s my question. If there are showers in one building does the second building need showers also? It is within 200 yards of other building. Again, both buildings are seeking LEED certification and their schedules are the same.A second related question relates to SS Credit 6.1. We\'re considering a cistern. Do both buildings need one to get the credit for both? Obviously if we only install one cistern to handle both buildings the cistern will be outside the site boundary for one of the buildings. Or do we need to install a cistern for each building so that cistern is located within site boundary for both?

Ruling:

The showers in one of your project buildings can be included in the credit calculations for both buildings, assuming the showers are within 200 yards of the entrance to the adjacent building. To demonstrate achievement for both LEED projects, be sure to demonstrate that the number of showers supports the occupancy for both buildings combined. The same logic applies to features such as a stormwater cistern. If the cistern is constructed to serve the needs of the building/site area in question, it can count towards credit achievement.

Inquiry:

We have two questions regarding this credit as it applies to our project: 1. Based on several CRIs, including the 9/10/2007, we understand that in principle as long as 90% or more of the total building area complies with the LEED requirement for the shower requirements and 100% of the building occupants are accounted for in the bicycle parking calculations, the credit intent is met and credit will be awarded. This is also supported by the LEED Canada NC 1.0 Application Guide For Core And Shell Buildings And Leased Tenant Spaces. It states that "To achieve LEED Canada NC certification, the base building and owner fit-up tenant spaces must be fit-up to comply with the LEED Canada NC requirements. In addition, sufficient leased tenant space must demonstrate that it has or will comply with the LEED Canada NC requirements so that overall 90% of the total building area complies with the LEED requirements." This 10% exemption recognizes the difficulty in getting multiple tenants to comply with LEED requirements. We see this as a good precedent to seek an exception for the small tenant spaces that occupy less than 10% of the overall area of the project. Our project is a single tenant class A office building which has about 1% of the total GFA leased out to two very small retail units that are not part of the otherwise single tenant building. These small retail units will have their own bathrooms and their occupants are counted in the overall building bicycle parking calculations, but they do not have dedicated showers as this poses a serious security risk for the primary tenant (a Bank). Can you confirm that the above understanding of the exclusions up to 10% of the GFA for the shower component of the credit is consistent with previous CIR rulings and is acceptable in pursuing this credit? 2. The other part of the question deals with locating shower and bicycle storage off site but within 200 yards. Our LEED Project meets the criteria for this as the Head Offices of this Bank is just down the street with gym facilities including showers. What we would like confirmation whether the sizing of the shower facilities and bicycle racks needs to be based on the occupancies of BOTH buildings or just our project that is pursuing LEED certification. The numbers are as follows: Our LEED Project: There are 436 Full Time Equivalent Staff and 119 Visitors. Head Office 200 yards away: Full Time Staff at Head Office is 516 persons. If we were to provide bicycle storage only for our LEED Project we would only need 22 racks for full time staff plus 6 more for visitors = 28 racks total, and 3 showers ( 1 for every 8 racks serving full time staff only) If we were to provide showers and bicycle rack for BOTH facilities, using only use the Full Time Staff numbers from both facilities, the calculation is as follows: 436 at LEED Project + 516 at Head Office = 952 Full Time Staff x 5% = 48 bicycle racks (rounded up) Showers are counted at 1 shower per 8 bicycle racks, therefore 6 showers would be required to serve BOTH building\'s full time staff. Based on this scenario, we understand that accommodating for 48 bicycle racks and 6 showers at Head Office should fulfill the credit intent and requirements, but seems like it is overkill. Previous CIRs indicated that in such cases, visitor transient populations can be omitted from the calculations. We would like to think this is applicable in this case since we would be almost doubling the shower and bicycle rack requirements. Please confirm if we should base our calculations assuming providing racks and showers for BOTH buildings (our LEED Project and Head Office) full time staff only (excluding visitors), or it is enough to provide only 28 racks and 3 showers to serve our LEED project only.

Ruling:

The project team is seeking clarification on two separate issues - firstly, the applicability of the credit requirements for showers relative to the small retail units (representing less than 1% of the GFA), and secondly, the calculation methodology that should be adopted when bicycle racks and showers are being provided in an adjacent building. For the first question, it is acceptable for the retail units to be excluded from the shower requirements given the small floor area of these units. In regard to the second question, the number of bicycle racks and showers must be sufficient to meet the LEED project requirements only, and does not account for the other building\'s occupants. It is however encouraged to provide a sufficient number for all building occupants (irrespective of LEED certification pursuits) where possible. [The following clarification was added 7/1/2012:] Note this LI is only applicable to projects with a nonresidential square footage one percent of gross floor area or less.

Inquiry:

Two of our projects are supermarkets registered under the LEED NCv2.2 rating system. Because of the uniqueness of the grocery retail building type, we utilized strategies from the LEED for Retail Pilot program to help make sense of some of the LEED-NC credits in the retail environment. Case in point, our energy modeler had to utilize the LEED for Retail application guide to model the heavy refrigeration loads of the building because the LEED-NC Reference Guide & ASHRAE 90.1-2004 Appendix G make no accommodation for it. Similarly, the Sustainable Sites 4 group of credits is in many ways does not fit well with the drastically different occupancy of retail from a typical office building. In the specific case of Bicycle Commuting, it is simply not appropriate to provide showers to retail customers and these can cause personnel problems when provided to retail employees. Furthermore, providing carpooling spaces to retail customers does not achieve the intended benefit, as the meaning of carpooling is called into question. The AGR has made great strides in tailoring the LEED-NC rating system to the unique characteristics of retail buildings by allowing multiple compliance approaches to provide an effective means of encouraging alternative transportation. Unfortunately, we had been inadvertently led by the USGBC to believe (and communicated to our clients) that we could utilize the AGR on our LEED-NC projects even during the Retail pilot prior to being fully balloted. We request that the LEED for Retail TAG allow our team to use the SSc4 credits from the AGR on these supermarkets in a manner similar to the way clusters of credits are currently allowed equivalency across already-established LEED rating systems. Specifically, can we would like to utilize the Bicycle Storage & Changing Rooms and Parking Capacity credit interpretations from LEED for Retail in these two LEED NC registered supermarkets.

Ruling:

This CIR is seeking permission to substitute the LEED for Retail credit requirements on a project that is otherwise certifying under LEED-NC. The project has requested permission to substitute the requirements for SSc4.2-Bicycle Storage and Changing Rooms and SSc4.4-Parking Capacity. Per the SSc4.2 CIR ruling of 10/17/2007, the project is allowed to use the credits as outlined in the LEED for Retail-NC rating system as long as the pilot program is underway. Following the full balloting and adoption of the LEED for Retail-NC rating system, the project would be required to switch from the NC 2.2 to the Retail-NC rating system to use the credit requirements.***Update 1/1/13: This LI is non-applicable to versions of LEED other than LEED 2009.

This credit interpretation request is in reference to LEED-EB requirements for a 497 000 s.f.g. Convention Centre located in Quebec City (Canada), winner of the 2006 AIPC Apex Award for the World\'s Best Congress Centre given by the International Association of Congress Centres. The Quebec City Convention Centre (QCCC) has for mission to welcome conferences, meetings and large-scale exhibits by offering an international convention facility. Three (3) user types are indicated for the congress Centre: administrators, organizers and visitors. 1. Most of the administrators (approximately 70 people) carry on their functions from an adjacent building from the convention Centre. Only three employees are working on a daily basis in the centre in period of event. These full-time employees shall be included in calculations. 2. Organizers are exclusively subcontractors. The Centre doesn\'t have any direct employee appointed to events organization. Number of organizers shall be estimated to be included in calculations. 3. Visitors represent the majority of building occupants. Visitors do not qualify as transient occupants because most of them use the Centre for at least one day/event. All events held at the Centre cover a period, in average, of 340 occupation days per years. Some events require the visitors\' presence inside the Centre for a period of more than 8 hours. Some events require the visitors\' presence for less than 8 hours. Number of visitors shall be estimated to be included in calculations. Occupants\' estimation Administrators: The number of three full-time employees will be used in calculations. Visitors: According to administrators\' projections, the number of visitors attending events held in the Centre (short and long period) can be divided on a basis of 8 hours of occupation to estimate an average of occupants/day. The Centre is monitoring the number of entrances/event. The exact number of participants from the two last years\' data would be used to calculate (on an 8 hours basis) the number of daily regular occupants. Organizers: All organizers are subcontracted by the QCCC. The QCCC doesn\'t keep track of many employees from each subcontractor is working inside of the Centre. However, the Centre administrators estimate from their experience the number of organizers/day required to set up and operate an event to 4%, in average, of the total participants attending an event. Are the 2 above estimations acceptable in order to complete calculations/requirements of credit SSc3.2 of LEED-EB V2.0?

Ruling:

The above estimations appear reasonable with the following notes: Bike racks and showers require different occupancy calculations. For showers, occupants should be considered individuals who regularly spend a full working day at the facility. This would seem to imply administrators and organizers (but not visitors) in this instance. Bike racks, however, should include visitors in the occupancy calculation as you have suggested in the \'occupants estimation\' above. Also, please note that it would be unusual for a 500,000 square foot convention center to have a full-time staff of only 3 employees. Please ensure that occupancy calculations include management, staff, food services, and particularly custodial services, (unless those services all fall within the \'organizer\' category as well, in which case you have addressed them already).

Inquiry:

The intent of this credit is to reduce pollution and land development impacts from automobile use. Pacific Garden Mission (PGM), a homeless shelter for homeless men and women in Chicago, is proposing an alternate calculation for the required bicycle storage capacity for this facility. PGM has four types of occupants: Transient-homeless; Program-people, Resident-staff and Commuting-staff. The Transient-homeless are the primary occupants. Averaging about 800 people, they come and go nightly with only what they can carry in bags, suitcases or backpacks. They certainly do not have cars or bicycles to use and/or bring to PGM. They stay temporarily at PGM-not long enough to qualify as residents or to enable them to even consider acquiring a bicycle. Therefore, it does not seem appropriate to include them in the calculating the required amount of bicycle storage. We propose to not require bicycle storage for the Transient-homeless population at the facility. Program-people are homeless people who are enrolled in training/education programs at PGM. The average program person resides 45 days before moving on. These 140 people are not long-term residents but some may have the opportunity to acquire a bicycle during their 45 day stay. Most likely it would be a used bicycle that would be kept outside. We propose to allocate outside bike storage for 5% of the Program-people. (140 x 5% = 7 outside spaces). Resident-staff work and reside at PGM. Of the sixty (60) total staff, forty (40) are Resident-staff that live at the facility and twenty (20) commute. The Resident-staff typically stay for 2 to 3 years and are therefore able to own bicycles. As such, the project team proposes to calculate the amount of bicycle storage for Resident-staff as detailed by the LEED Reference Guide for a residential facility. This means that covered bicycle storage for 15% of these occupants must be provided. (40 x 15% = 6 covered spaces) For Commuting staff, the need for bicycle storage for staff will be calculated as detailed by the LEED Reference Guide for a commercial facility. This means that bicycle storage for 5% of these occupants will be provided, plus separate showering facilities as per the LEED Reference Guide. (20 x 5% = 1 outside space) In summary, the proposed changes are to: 1) Not allocate bicycle storage for the Transient-Homeless population since they do not have, nor is it practical for them to have, bicycles; 2) Allocate outside bicycle racks for 5% of the Program-People. 3) The resulting proposed required amount of bicycle storage and the actual storage in the design are summarized as follows: Occupant Type #Occupants Typical Duration of Stay Type storage % of occupants served # of bikes stored Transient-homeless 800 1-2 days overnight N.A. 0% 0 Program-people 140 45 days overnight Open 5% 7 Resident staff 40 2 to 3 years Covered 15% 6 Commuting staff 20 One 8-hour shift/day Open 5% 1 Type storage # bicycles stored # bicycles stored # extra spaces Proposed Requirement In The Design In the Design Open 8 18 10 Covered 6 7 1 Note that the design does call for a number of extra spaces that could be allocated as needed among the all the various occupants. Please let us know if this alternative method for calculating the requirements of SS Credit 4.2 is acceptable.

Ruling:

The applicant is requesting clarification about how bicycle parking requirements pertain to overnight homeless residents and longer-term homeless residents in a homeless shelter for homeless men and women in Chicago. Given the specific circumstances of this project, the proposed approach of exempting the overnight homeless residents from bicycle parking requirements is appropriate. However, the longer term Program-people must be included under the residential requirement of covered bicycle parking for 15% of occupants, as these occupants reside in the building and bicycle use may be offsetting car, bus or other transit trips. The proposed calculations for resident staff and commuting staff are appropriate. Applicable Internationally.

Inquiry:

We are requesting a ruling about how occupants should be calculated in SSc4.2 for our project, which is a professional hockey arena. A previous CIR Ruling (9/14/2006) established that "Excluding a certain type of transient occupants from the required bicycle stall and shower calculations is permissible per previous v2.1 CIR Rulings dated 6/4/2003 and 8/7/2002. Please include a short narrative indicating the number of visitors who have been excluded from these calculations and an explanation of why this type of visitor cannot reasonably be expected to arrive at this destination on or with a bicycle that would benefit from onsite storage facilities." These CIRs related to projects which were destination resorts and airline terminals. Our project, a professional hockey arena, has similar occupancy concerns that make it impractical to provide bicycle racks for all transient occupants. Because the largest events (hockey games) are held late at night and because many event attendees are coming from far away, it is much more likely for attendees to carpool and use public transit than to ride a bicycle. The project anticipates achieving SSc4.1 (numerous bus lines within 1/4 mile and a rail line within 1/2 mile) and SSc4.3 and 4.4 (preferred parking for carpools and efficient vehicles). In addition, for SSc4.2, the project will be building a new bike path to encourage bicycle use, especially during daytime events. Thus, we have developed ways to address both daytime and nighttime events, as described below: For daytime events, our project team has identified two options to address the intent of SSc4.2 that we would like to get direction from the USGBC on: 1. Provide 100 secure bike racks for 5% of the FTE staff plus 5% of the transient occupants who attend daytime events. Peak occupancy during daytime events is expected to be for tradeshows that occupy the main hockey floor space. For this use, occupancy is expected to be about 2000 people for the peak event time. This figure represents about 300 operation/vendors, 1685 attendees and 15 staff. Thus 100 bike racks represent 5% of this occupancy to satisfy the intent of credit SSc4.2. OR 2. Provide 50 secure bike racks for general-use occupancy and require the Events Operator to set up a secure bike corral for at least 50 additional bike racks for any event that anticipates attendance in excess of 1000 people for its peak occupancy time. Nighttime events will be larger, up to 6000 people (peak concert); but as noted above, late egress will discourage bicycle ridership such that peak use will be less than daytime events. For nighttime events, we feel it is only reasonable to expect attendees to ride a bicycle if they live within 5 miles of the arena. The website CommuterChoice.com notes that the average bicycle commute in the US is about 2 miles, so we feel that this allowance of a 5 mile bicycle commute to the arena at night is an aggressive expectation. Our transportation consultant has estimated that about 7% of attendees live within 5 miles of the arena. Thus, for the maximum event of 6000 people, the number of attendees living within 5 miles of the arena would be 420 people. Staff/vendors at this event would be 315, making a total of 735. The 100 or 50 bike racks that would be provided for the project thus represent respectively 13% and 7% of the nighttime occupants who might be expected to commute by bicycle to the event. Showers will be provided to meet the requirement of 0.5% of FTE staff for all events (both daytime and nighttime). The project team feels that this night-time approach and both the daytime options meet the intent of SSc4.2 for this type of facility. We request that the USGBC either confirm that our approach is valid for both daytime event options and nighttime events, or provide clear guidance on how our assumptions should be modified to meet the intent of SSc4.2.

Ruling:

The CIR is requesting clarification on calculation of occupancy for a large sports arena in order to provide the appropriate number of bicycle racks. The team has provided multiple assumptions and calculation methodologies and is requesting guidance on which approaches should be used. 1. The team has presented assumptions regarding which transient occupants can be expected to use bicycles to reach the event. The team assumes that visitors coming to the site at night are less likely to ride bikes than those coming during the day due to safety concerns, and therefore more there will be a higher demand for bike parking in the day, even though peak occupancy is lower. This is potentially a reasonable assumption, given that the project team provides clear information on the types of day and night uses, the hours of operation, the peak occupancies of each use and other relevant justifying information or data. 2. The team has stated that visitors living within a five mile radius of the site are the most likely to travel by bike, and therefore bikes should be provided for local visitors only. Focusing on local visitors is an acceptable approach for calculating transient occupants but not regular occupants. Additional information would be required to support the use of a 5-mile radius, as well as to support the calculation of the percentage of visitors within this radius. Detailed calculations from the transportation consultant or other relevant data would be required in order to use this approach, which will be evaluated on a case-by-case basis. Reviewers will take into consideration building type and program, location, bicycle network and other variables in evaluating the merits of this approach. 3. The team has presented two strategies for providing bicycle storage—either permanent secure bike parking or valet service for bike storage. Either approach is acceptable. If a valet service is being used, refer to the requirements included in NC v2.2, SSc4.2 CIR ruling 10/24/2007.

Inquiry:

Establishment of baseline FTE for a Transient Facility:This Washington, DC Major League Ballpark experiences a transient population roughly 81 times per year on "event" days only (a ballgame). The project team developed a calculation to determine the number of Full Time Equivalents that would become the baseline for the bicycle racks and showering facilities required. The team originally took the full time building population (250 occupants at 8 hours per day/total person hours per day/260 annual days of occupancy/total person hours per year) and a part-time population count based on the number of fans that would be attending an event in equivalent hours (35,000 avg. game attendance at 4 hours per day/total person hours per day/81 annual days of occupancy/total person hours per year) for a total FTE of 5702 occupants.Bicycle Racks Calculation:With a baseline FTE of 5702, the total number of bike racks required to satisfy the credit requirements are: FTE = 5702 * 5% = 286 bike racks required.Original Solution:In order to support bicycle transportation as a viable means of accessing the Ballpark, the District of Columbia Department of Transportation (DDOT) is donating 286 bicycle storage racks which will be located around the ballpark site, convenient to multiple points of entry (within 200 yards). Secure bicycle storage is provided in the garage for full time employees. The Ballpark team submitted documentation to this effect on July 30, 2007. In addition to 286 racks on site, DDOT will be installing racks on surrounding blocks, however the exact number and location is not determined at this time. The Ballpark team felt this met the intent of the credit by supporting the use of bicycle transportation to and from the Ballpark, however the credit was denied in the design phase review (with request for clarification).Design Phase Review Response:"The LEED Submittal Template has been provided claiming that the project has provided bicycle storage and shower facilities for 5% of the FTE building occupants. For this credit, the peak number of transient occupants should be included in the FTE occupant count. For a ballpark, transient occupants will be at the stadium at the same time, so the peak occupancy should not assume a diversity factor, but should include all guests and staff that are likely to be at a ballpark during a sold-out game.TECHNICAL ADVICE: Please provide revised FTE occupancy calculations that account for transient visitors at peak occupancy. The calculations should include the peak number of transient visitors expected to visit the building at any given time."Revised Calculation:If we add the peak attendance of 41,000 (sold out game) plus 250 FTE, the credit would require 2,064 bicycle storage spaces. According to the Executive Director of the Washington Area Bicyclist Association (WABA), this exceeds the bicycle storage capacity at Amsterdam Central Station and would constitute about a linear mile of bicycles. The WABA has over 7,000 members, yet the Executive Director remarked that providing nearly 300 storage spaces is already probably in excess of need, let alone over 2,000.The Ballpark team also finds 2,064 permanent storage spaces to be excessive for numerous reasons:The LEED Rating System (and this credit) was originally developed to address commercial office buildings. Whether by bicycle, private car or public transit, both FTE and Transient populations typically arrive at buildings of this type individually rather than in groups (unless they are carpooling, which is addressed by another credit). Ball games tend to be social events, primarily attended by groups of people rather than by individuals. The Ballpark project has already been approved for an exemplary performance ID credit under Transportation Management Plan for its plentiful access to public transportation and for not providing public parking.While the Ballpark team does anticipate some individual attendance at games (a portion of which may arrive by bicycle), there is no evidence to support the expectation of anywhere close to 2,000 cycling attendees. Indeed, the San Francisco Giants stadium provides a bicycle valet for 150 bicycles and is only currently storing up to 125 bicycles on game days.The Ballpark team feels providing an excessive amount of permanent storage at this time is contrary to the general underlying environmental intent of the credit. The production of these racks will require the use of materials - both raw and recycled - in addition to the energy that will be used to manufacture and transport the racks. If the San Francisco stadium is any indication, only about 6% of the 2,064 racks would be used.2,064 racks will also require a large amount of land to be set aside for this use, and on a compact urban infill site the Ballpark team does not feel providing racks in large excess of demand constitutes the highest and best use of the land.An alternative solution has been developed, one the Ballpark team feels bridges the gap between providing permanent storage capacity for 2,064 bicycles and our original proposal of 286.Alternative Solution:The Ballpark team proposes to continue with installation of 286 permanent bicycle storage racks and to provide an additional bicycle valet service on game days. This is a more flexible and environmentally sensitive solution to permanent racks, and can be quickly responsive to growing demand.We propose to model our Ballpark bicycle storage capacity both on that of the San Francisco stadium and on the LEED-EB Rating System. In addition to 286 storage spaces, the Ballpark will offer valet service initially for up to 150 bicycles. The WABA has agreed to provide valet service. The Ballpark owners have agreed to offer \'ride-to-the-game day\' promotions that will encourage the use of bicycle transportation through reduced price game tickets on certain dates. At special events such as this, the bicycle valet capacity would be increased beyond 150 to anticipate larger demand.The peak demand will be monitored and valet service capacity will be increased every season that there is an increase in peak usage so that the bicycle storage capacity is maintained at 125% of the peak demand for bicycle parking until a maximum bike storage capacity of 5% of the peak building users is reached (or 2,064).ConclusionThe unique nature of this project type requires a creative approach to this credit. We feel that by committing to providing a combination of permanent storage and a storage service that will enable Ballpark employees and visitors to bicycle to work and games, we are meeting the intent to reduce pollution and landscape development impacts from automobile use.

Ruling:

Given the particular nature of this project, the proposed Alternative Solution does meet the credit intent as it allows for capacity growth based on peak demand. This approach is applicable to stadiums and special event facilities only. Along with required credit documentation, please provide documentation demonstrating an ongoing bicycle valet service program (a signed contract for the service is acceptable) which includes stipulation for increased growth based on demand up to 2,064 bicycles.Please also provide a narrative which details how demand will be monitored and capacity increased over time, along with a description of how and where bicycle storage sufficient to accommodate up to 2,064 bicycles will be provided should there be that level of demand.Note that showers and changing facilities must be made available to all full-time equivalent (FTE) employees.

Inquiry:

We are requesting a ruling upon which occupants shall be included in the bicycle and shower calculations for SSc4.2. A previous CIR Ruling for LEED-NC 2.1 (dated 06/04/03) stated that an international airline terminal could meet the intent of this credit by providing adequate bicycle spaces and changing/showering facilities for only the staff employees if the calculation included all staff and the project maximized alternative transportation opportunities for transient occupants. Our project, a large destination resort, has similar occupancy conditions to the above-referenced CIR Ruling that make it impractical to provide bicycle racks for the transient occupants. Our project contains the following uses: hotels, condominiums, retail shops, conference center, theater, gaming, and restaurants. As a result, we propose to identify three types of occupants in this project - employees, condominium residents, and transient guests. Our transient guests travel from around the country and the world and arrive via the airport or long distance car & bus trips. These guests are served by a variety of alternative transportation services such as monorails, city buses, a tourist trolley, and hotel shuttle buses. Consistent with the resort\'s commitment to integrating environmental sustainability into the project, we will be making a substantial investment in supporting bicycling. We are planning to provide over 300 bicycle spaces and the associated number of showers, based on our employee counts. The impact opportunity is substantial. Since the commuting characteristics of this project are similar to the airport terminal situation described in the previous CIR, with the addition of a residential component, please confirm that we can achieve this credit by providing bicycle spaces for 5% of peak on-site employees, showers for 0.5% of peak on-site employees and bicycle spaces for 15% of condominium residents.

Ruling:

Excluding a certain type of transient occupants from the required bicycle stall and shower calculations is permissible per previous v2.1 CIR Rulings dated 6/4/2003 and 8/7/2002. Please include a short narrative indicating the number of visitors who have been excluded from these calculations and an explanation of why this type of visitor cannot reasonably be expected to arrive at this destination on or with a bicycle that would benefit from on site storage facilities. It is not acceptable to automatically exclude all transient visitors from these calculations as it is reasonable to expect that some of the visitors to the retail shops, conference center, theater, and gaming facilities could potentially arrive on a bicycle, therefore please be certain to include these areas, when appropriate, in the bicycle stall calculations. The proposed strategy to provide bicycle stalls for 15% of condominium residents is consistent with credit requirements for residential buildings. Applicable Internationally.

Inquiry:

We are requesting approval of an alternate compliance path with regards to the quantity of showers required to comply with Sustainable Sites Credit 4.2 in the LEED NCv2.2 rating system. Our project, located in Cairo, Egypt, provides areas within the building for prayer and ablution areas adjacent to it used for ritual cleansing before prayer time. Each ablution area, one each for males and females, will have four sinks that are actually shower-like faucets on a wall above a trough for a total of eight sinks. We will send a photo example separately. There are no walls or enclosures around each of the sinks, although there are separate ablution areas for men and women. Users remain robed while using the sinks, except for socks, shoes and jackets. Users will typically roll up their sleeves and using a washcloth wash their arms, armpits, face, hair, feet and lower legs. While these ablution areas are used for religious practice, it is common and socially acceptable to use them for general washing as well. Furthermore, social norms do not dictate full daily washings that are typical of American culture, making "sponge" bathing a more common practice for personal hygiene for the majority of the population. We are proposing that each bathing fixture in each ablution area be counted as an individual shower, in our case eight in total. In order to fulfill the need of all occupants of the building, four regular showers, two for each gender, will also be provided in the building for occupants that wish to use a full shower and changing facility. Our building has an FTE of 1080, which requires 5.4 showers, or 3 for each gender. We believe that access to the 4 showers and 8 ablution sinks meets the intent of the credit while also being more appropriate for the social customs of the culture. Is this approach acceptable?

Ruling:

The project is located in Egypt and is seeking confirmation on whether the use of ablution sinks can be considered towards achievement of this credit. Based on the specific local religious and social customs, the use of ablution sinks can be deemed comparable to the use of showers, and can be included in the total number of showers required for credit compliance. However, in cases like this, at a minimum, 50% of the required number of showers must be provided by full showers/changing facilities, to ensure that all occupant needs are adequately met. The project team should include justification for this alternative approach in the LEED submission, clearly demonstrating that the majority of the building occupants adhere to these religious and social customs, and the associated use of the ablution sinks.
