FAQs about EAp2 :

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?

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?

EBOM-2009 EAp2:Minimum Energy Efficiency Performance

Server Room Submetering

I'm inquiring in regards to server room spaces within an office building up for LEED EBOM. We have a portion of our server rooms that are submetered and a portion that are not. The metered server rooms are made up installations ranging in size from 154 sq ft to 1,900 sq ft. First question: is there a lower size limit to what can be considered as "data center" space?" The second question is in regard to submetering. I have been told that there is a UPS, but that our metering covers the input energy. Is this acceptable or does the UPS output need to be metered? Any feedback would be greatly appreciated.

Hi Patrick, For your first question: refer to the definition of "data center" in Energy Star terms. This is typically not a server room or closet although commonly mistaken. Data Centers typically have raised floors, separate HVAC and air distribution systems. On your second question, the sub-metering must be on the output of the UPS in order to receive the correct Energy Star Score. You can always take the alternative paths to meeting this credit. to get passed Energy Star

what is the alternative path? if it is an office building, isn't energy star required? I have the same issue as described: office building with a data center (bank building)
