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

Case 2 calculator vs. Statement of Energy Performance

When I generate a Statement of Energy Performance for a non-rateable building, the SEP tells me that my building uses 23% less energy per square foot than the national median. 2 points, yay! When I plug the Site EUI into the Case 2 calculator, I am only 18% above the national average and don't even meet the prerequisite, boo! What gives? Can the SEP figure be used instead of the case 2 calculator? Why are they different?

Boo! is right but alas, the Case 2 calculator is the authority here. One reason for the difference might be that the Case 2 calculator assesses the percentile points above the national median rather than the percent reduction from the national median. The relationship between the percent reduction to the percentile points above the national median is not a linear one. But, at least the building is very close to meeting the prerequisite.

Hi Emily, Are you benchmarking your classroom buildings under Other - Educational or Just Other-Other. We are starting to work on a University project and thought you would be the best person to verify that with. Thanks
