FAQs about EAp2 :

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?

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?

EBOM-2009 EAp2:Minimum Energy Efficiency Performance

Equipment turned off

Does anybody know whether chilled water and AHU's must be operating to use portfolio manager. We have a client that just does not turn on corridor 100% OA units for his building. As a result, a second chiller is literally never utilized. Cooling towers are always operating at half their capacity. The building scored a 98 on portfolio manager. Fantastic score but it seems kind of unethical to not inform USGBC that some equipment is perfectly functional but just turned off.

Turning things off is one (very good) way to increase your PM score. There's nothing unethical about not running the equipment from the energy use perspective.

Good question, but why would the corridor units be 100% OSA? Also, what are the CO2 levels and occupied space temperatures like? I don't think it is ethical to allow your air quality and space temperature control to deteriorate in the name of saving energy.

Good point Peter - I actually thought of that. If IEQp1 is met then is it unethical to provide less than the maximum possible? The trade off between energy and occupant health and comfort is a difficult area... Whether they should operate is one question, whether you need to tell GBCI they are not operating is another (although they should be able to see that in the BOP.)

What is the building function? There is natural ventilation?
