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

Portfolio Manager for Dormitories

We have an 180,000 sf dormitory and trying to get an ENERGY STAR rating through Portfolio Manager. We have run into some issues with our facility because the dorm consists of 4 dormitory housing buildings (over 40,000sf) and 2 small office and study buildings under 5,000sf. They are all under the same management, same meter and operate as one facility. In order to get an ENERGY STAR rating, we have to separately rate each building. Because the 2 small office and study buildings are under 5,000sf, we can't get a rating for them. Is there a way to get a rating for the whole dormitory facility or will LEED allow us to exclude the two small spaces because they are under 5,000 sqft?

John: This issue can get real tricky real quick, so I'm not surprised it's come up. Before we get too far into the weeds here's a general rule of thumb: if you can find a solution using existing, published guidance then you should try that, as it will minimize your risk of delaying the LEED review. This rule may sound obvious, but what makes it complicated for your topic is that several pieces of guidance out there might offer ideas or pieces of a solution but they're in different places: 1) ENERGY STAR's rules about how to treat multiple buildings 2) USGBC's rules on multiple buildings, as described here: http://www.usgbc.org/DisplayPage.aspx?CMSPageID=2326 3) USGBC's rules related to the MPRs, which define which projects are a good fit for LEED itself: http://www.usgbc.org/DisplayPage.aspx?CMSPageID=2102 So I'd suggest skimming each of these resources and seeing if any pre-approved solution jumps out at you. If it doesn't, then check in here again and we can take a deeper dive.
