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?

Greetings, I am trying to benchmark a medical devices manufacturing facility using Portfolio Manager and LEED EBOM Option 2B since this facility is not eligible for and Energy Star score. If I'm using 2013 as my performance period I would need to normalize 2010 through 2012 to make my comparison?

Omar, Yes, that's right. For Option 2B, you need to compare the performance period year against 3 consecutive years within the past 6 years. You'll also need to normalize the energy use for those historic years. Often, the normalization is done using the production of the facility over the historic and performance period years.

Thanks Ben. I'm using the DOE EnPI to normalize for production. It gives me the EUI in terms of MMBtu/unit. How do I use that info on the EAc2 Calculator which requires kBtu/sf?
