FAQs about EAp2 :

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?

EBOM-2009 EAp2:Minimum Energy Efficiency Performance

Benchmarking of an office building with atrium

Dear all, We are working on three similar buildings in Serbia. Energy consumption of all three buildings is being uploading to the Energy Star Portfolio manager. Thing is that one building achieved score of 64 which is almost 10 points less than other two. Reason is, that this building has a quite extensive roofed atrium inside and therefore office sqft/kWh ratio is lower than in an average office building without an atrium inside. Has anybody an idea how to deal with it? Thank you in advance!

Jiri: One option is to separate out the roofed atrium space, and its associated floor area, in the building description within ENERGY STAR and assign it a different type of space usage.

Hi all, Just to make sure we are on the right track, the "USGBC's alternative energy performance calculator for non-ratable buildings" that Mike is talking about is the "EAc1 EBOM 2009 Case 2 Calculator V1.xls" found in the credit resources in LEED Online? I haven't been able to find a document called "USGBC's alternative energy performance calculator for non-ratable buildings" and I would like to make sure I have all the documentation. If anyone can confirm my suspicion or direct me to the appropriate document it would be much appreciated.
