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

Labs21

Hallo, We are certifying a LEED EBOM project composed of 28% laboratory and 72% office. The Case 2, Option 1 Labs is asking to enter to parameters: i.This Project Building's annual weather normalized Source Energy Use Intensity from Portfolio Manager. ii.Peer Facility Average (from your Labs21 Benchmark Statistics) My questions are: -Do we have to include the whole building energy consumption in the Portfolio Manager (laboratory+office) or just the office space? -Do we have to include the whole building energy consumption in the Labs21 tool or just the laboratory? Our concern is not to double count the energy consumed in the laboratory.

Hi Gustavo, I believe the answer is yes, that you must include whole building consumption on Portfolio Manager and within the Labs21 tool. I believe that the Labs21 data set includes whole building usage and that part of generating an appropriate peer group within Labs21 depends on the portion of the building that is laboratory space. Have you tried that an are getting an unexpected result?

Yes, the calculator says I will achieve 14 points. I have just found out that Labs21 always classifies by buildings in the climate zone 5A, but my project is in zone 3A. I do not know how to change this parameter. Does anyone know?
