No, this type of claim does not adequately verify the level of recycled content in the purchased item because there could be a high level of variation across products.
The LEED-EBOM 2009 rating system offers a 10% floor area exemption option for multitenant buildings. In instances where tenant data cannot be gathered, or the EBOM applicant does not have control over tenant operational practices, the project team may exclude up to 10% of the building’s gross floor area for any prerequisite or credit. See page xxii of the Reference Guide for further information.
Only ongoing consumable goods that are used within the scope of the LEED project boundary should be included in MRc1.
While the ideal solution is to develop a way to track items that are purchased and used within the scope of your LEED project boundary, some projects may find that this is not possible. An alternative method for compliance you may consider attempting is to take an organization-wide approach to satisfying the credit requirements. To do this, thoroughly document the sustainability criteria met for total organizational purchases, and then extrapolate this performance to the project building.
Purchases of the same product can be aggregated into a single line item. (For example, if you made five purchases of XYZ Green Window Solution, Item #44556 at $8.99 per purchase, the product can be aggregated as $44.95 in the credit form). However, each different product must be listed in a separate line so that the review team can confirm that supporting documentation for at least 20% of products has been provided.
It depends on the specifics, including square footage. LEED Interpretation #10209, issued 7/1/2012, states that “If the total nonresidential square footage of a mixed-use building is less than 10% and no greater than 5,000 square feet, it is acceptable for the nonresidential use to be excluded from the shower requirements.” Bicycle storage requirements must still be met, however.
In all cases, round up. Round up 0.5 showers to 1.
LEEDuser's experts have seen this credit approved with similar strategies. Check that each unit has its own storage area that is large enough for a bike, and that there is enough other storage in the unit for other common items like boxes of clothing, etc. A common-area storage room that could get filled up with non-bike stuff could be a problem, however. Be sure that the intended solution will really work.
Possibly. LEED Interpretation #2422 made on 01/23/2009 states that "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."
