FAQs about EAp2 :

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?

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?

EBOM-2009 EAp2:Minimum Energy Efficiency Performance

What About Multi-Family Residential Buildings?

Multi-family residential buildings are currently not eligible to receive an Energy Star score in Portfolio manager. Also, they do not have data on national average EUI to use for comparison to show efficiency improvements. Does this mean that multi-family residential projects cannot get certified under the LEED-EBOM system since they cannot meet the prerequisite? Is there any guidance on what multi-family projects should do? Has anyone attempted this on another project. Any help is appreciated! Thanks.

Lance, Have you tried the USGBC EAp2 Case 2 Calculator for buildings that aren't eligible for Energy Star? There is a "Lodging - Residential - Multifamily" space type avaialable there. The link above didn't work for me just now, but you can also find the excel file linked at: http://www.usgbc.org/DisplayPage.aspx?CMSPageID=2084

Lance...how big is your multifamily building? If there are four or more habitable stories, your building qualifies. As Tristan notes, you'd use the offline calculator to performance the energy benchmarking (which incorporates information from the DOE national residential building energy consumption survey - like CBECS but for residential). If you do go forward with this project, know that there are several credits for which compliance in a multifamily building is not straight forward, and you should use GBCI customer service and/or CIRs to get as much advance clearance on alternative compliance paths as possible.
