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

Case 2 Calculator - Space Types

Our project is a mixed use building used by community groups and has several different space types within it (theater, classrooms, event areas, kitchen, offices). Can I break these spaces out on the Case 2 calculator by square footage essentially creating a weighted average for the building's adjusted national average EUI? I'm assuming I can because there are multiple blank lines for spaces types on the calculator. Has anyone tried this in the past?

Timothy: Yes, you are correct - you should break these spaces out by floor area in the calculator. The blank lines are in there for exactly this purpose. However, do keep one nuance in mind - you should break out the space according to the overall function of that part of the building, and avoid too much granularity. E.g., don't break out "kitchen" as a separate type, rather, since kitchens are always auxiliary to some other function, lump the kitchen floor area in with the broader usage category that aligns with most users of the kitchen, like "office" or "classroom".
