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

Monthly energy use data

Hello, does anyone know, whether energy data used for the Energy Star Portfolio Manager rating have to be based on monthly summaries or if they can also be submitted as quaterly or annual summaries. We know from the Energy Star Portfolio Manager that there is no longer the 65 day limit on entering energy meters to generate an Energy Star rating. But does the GBCI also accept energy data summarised quaterly? The Reference Guide only states that "a full 12 months of continiuous measured energy data is required". But the LEED Submittal Tips talk about "monthly energy use summaries" which confuses us. Has anyone experience with this issue, found a clarification or has handed in quaterly or annual energy use summaries? Thank you very much

Hi Julia The energy data used for Energy Star Portfolio Manager does not need to be based on monthly summaries and in fact should be based on the actual usage dates - this is extremely important so that your score is normalized based on climate data. One example that I would use to confirm this approach is that we have many projects that have emergency back-up generators. However, these systems only use energy in one-time events, so we only enter use during these times. And this has historically worked. Let me know how else I can help Thanks Hannah
