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?

In my project there is an absorption chiller supplied by district heating. The building itself is also heated by district heating. The two district heat quantities (one for heating, one for cooling) are metered separatly. Would it be right to enter the two meter to Portfolio Manager? If both account for heating, that wouldn't make sense. has anyone of you a solution? Thanks!

The energy usage should be based on whatever is coming from outside the property, so if there are two separate steam meters then both would be included, even if some of the steam is used for cooling equipment rather than heating. If one of these was a submeter to the other, then only the main utility level meter would be included. From your description of separate meters, both would be included in Portfolio Manager.
