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

District Co generation Plantby

Hi, The building is catered by own chiller plant located in the building & building owned DES Cogeneration plant for the space cooling. The electricity for the building is from building owned DES & third party electricity board. if the whole building is catered by the Cogeneration plant. I can use DES allocation calculator & DES guidance. but in this project the the electricity is from third party & cogenration plant. How I need to document the above case for LEED EB O&M 2009 EAP1?

Satheesh, First of all, I assume your question is about EAp2 (not EAp1 as your inquiry's text says). Two forms of energy are relevant to your question: thermal energy (for space cooling) and electrical energy (general use). USGBC's published guidance for district/campus energy systems is mostly intended to establish requirements for allocating thermal energy, not electricity. Although electricity is important to consider in the cogeneration context, it is secondary to the thermal energy. Thus, since your building's thermal energy is entirely "Building-Owned" as defined by USGBC, I recommend that you use the standard DES guidance and calculator. You should also clearly explain that the electricity is not solely from a "Building-Owned" source in case the LEED reviewer has questions about that. As always, if you have significant doubts you should submit a formal CIR. Good luck.
