FAQs about EAc1 :

We have installed submeters on our building but the utility bill includes energy use from several other buildings located on the same campus. How do we reconcile this during the LEED review process?

When is it possible to exclude up to 10% of the building from EAp2?

What do I do if the number of building occupants, operating hours, or vacant space changes during the performance period?

If you pursue the streamlined path for an Energy Star label, should the performance period for EAc6 match the 12-month time frame of the label?

How do I account for computers with multiple monitors on Portfolio Manager?

How should I treat vacant space on Portfolio Manager?

Our building includes a large laboratory space. Can our project benchmark under the Labs21 program?

We have an international project and the space type is eligible for an Energy Star rating. Can we pursue Case 1 to demonstrate compliance given the recently released alternative compliance paths for international projects?

We have a number of buildings on a single campus that we would like to certify at the same time. Is it possible to benchmark the buildings at the campus level?

I have a mixed-use building and am wondering if it is possible to pursue the prerequisite through Case 1. How do we proceed?

We have a building that consists of two attached structures and it’s unclear if we have to consider it a single building or if it should be certified as two separate buildings and benchmarked accordingly. How should we proceed?

How long is an Energy Star label valid to use with a streamlined approach for Case 1?

Our building includes heavy process loads that significantly increase the overall energy use in the building. If we submeter these loads, can we exclude this energy use for benchmarking purposes?

Portfolio Manager - All Requests Suspended for Energy Star Scores Until Early 2019

I will assume most are aware that Portfolio Manager has suspended applications for Energy Star Certification from September 2018 until early 2019.  As a requirement for EAc1 to be earned, the submission of an Energy Star Score (if the building is eligible (which it always has been) is necessary.  With our project having to submit by February 10, 2019, I have concerns about not being able to provide an ES Score.  What is GBCI doing for all of the projects that have Performance Periods ending since October 2018 to potentially February 2019 as this situation is out of our control?  Would a verification (i.e.screenshot) of the current score be sufficient?

We used Energy Star Certification for our initial LEED submission (Gold) in 2014 and this is our Recertification, which is due by February 2019.

Thank you,

Michelle

I researched this challenge a little further and became aware of this ruling that basically answers my question.  I am posting because I felt there would be others that find this information helpful. Here is the link:   LEED Interpretation 10473 <https://www.usgbc.org/leedaddenda/10473> that addresses this issue. Rating System LEED O+M: Existing Buildings, LEED O+M: Schools, LEED O+M: Retail, LEED O+M: Data Centers, LEED O+M: Hospitality, LEED O+M: Warehouses and Distribution Centers, LEED O+M: Multifamily Rating System Version v4 - LEED v4, v3 - LEED 2009 Ref Guide Name and Edition v4: Building Operations and Maintenance, v4 edition Inquiry As stated on the ENERGY STAR website (https://www.energystar.gov/buildings/facility-owners-managers/existing-buildings/use-portfolio-manager/update-energy-star-scores-cbecs), the EPA is in the process of updating the Portfolio Manager tool to incorporate CBECS data from the results of the 2012 survey. At this time, EPA will also update: source energy conversion factors used in all ENERGY STAR score models; the underlying ENERGY STAR models for a number of property types; and benchmarking options for data centers. The EPA has indicated that there is no way to forecast the change in score for any particular property or property type. Is there an alternative approach project teams registered to pursue certification under LEED EB O+M v2009 and v4 can take in order to not be penalized by these updates under EA prerequisite Minimum Energy Performance and EA credit Optimize Energy Performance? Ruling Projects meeting the requirements below may optionally assess performance of EA prerequisite Minimum Energy Performance and EA credit Optimize Energy Performance based on the current Portfolio Manager tool and the performance of the building prior to the August 2018 updates. In order to pursue this approach, project teams must download the necessary documentation from Portfolio Manager (e.g., Data Verification Checklist, proof of weather normalized source EUI, etc.) before the updates go into effect (scheduled for August 2018). After the update, previous scores, including all historical scores, will no longer be accessible.

This approach is available to projects that started the last 12-months of the initial certification or recertification performance period prior to the date that Portfolio Manager was temporarily shut down to incorporate the planned updates (scheduled for August 2018), meaning that the project’s certification performance period ends on or before August 2019. 

• For buildings eligible to receive an ENERGY STAR score, performance is determined based on the ENERGY STAR score achieved prior to the August, 2018 updates. The ENERGY STAR score must be demonstrated through information printed from Portfolio Manager prior to the updates (e.g., Data Verification Checklist). 

• For buildings not eligible to receive an ENERGY STAR score under LEED EB O+M v2009, performance is determined based on the weather-normalized source EUI achieved prior to the August 2018 updates compared to the national average source EUI data provided in the current EAp2/EAc1 Case 2 Calculator for v2009 projects. The project’s weather-normalized source EUI must be demonstrated through information printed from Portfolio Manager prior to the updates: a screen shot from the Portfolio Manager website documenting the weather normalized source EUI value; or a custom output report including the weather-normalized source EUI). This information, along with the Data Verification Checklist and Case 2 Calculator, is required.

• For buildings not eligible to receive an ENERGY STAR score under LEED O+M v4, performance is determined based on the weather-normalized source EUI achieved prior to the August 2018 updates compared to the national median source EUI data provided in the Portfolio Manager tool. The Data Verification Checklist documenting the “% Diff from National Median Source EUI" is sufficient to document performance.

• In all cases, the 12-month energy performance period used for this allowance must end within the 60 days prior to the scheduled update. All space attributes (floor area, space types, occupancy, etc.) must be up to date and accurate at the time. 

• Sufficient information that aligns with the 12-month performance period used for this allowance must be provided. If information for the 12-month performance period used for this allowance differs from that for the remainder of the submittal (i.e., number of workers, operating hours, changes in space use such as vacancy and space type, etc.) a narrative justifying these differences must be provided.

One clarification is that these guidelines apply to buildings that had new scoring models, which were primarily the types based on CBECS and data centers. This may help some properties that are business as usual with ENERGY STAR (hospitals and multifamily for instance). The other clarification is that if you hadn't saved your data prior to the update, you can still use ESPM to show a current score, but you are not able to receive a label at this time. The benchmarking remains as the "best available source" for many property types even while labeling is suspended. Let us know what type of property you are working on and what's shown for the current score and maybe we can help.  Note: some types aren't showing scores right now (MOB's) which is a different issue than the recent algorithm updates. These will need to be addressed through alternative approaches.

Our building are all identical offices, and the scores only dropped a couple of points when Portfolio Manager update in August of 2018.  Luckily, I had saved the data in July of 2018, so I believe we will by okay.  I hope it stays this way until we submit in February.  I appreciate your further clarification regarding this issue.

Any idea what projects that are supposed to do when submitting in January 2019, with the Government shut-down and Port. Man. being unavailable?  For example, I need to send the project energy details to my Green-e contact and purchase, but do not have access to the data to create a report.
