FAQs about EAp2 :

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?

How do I account for computers with multiple monitors on Portfolio Manager?

How should I treat vacant space on Portfolio Manager?

EBOM-2009 EAp2:Minimum Energy Efficiency Performance

EAp2 Performance Tracking Period

Hi, I have a slight question regarding the start date for tracking the EA performance period. The project that my team is working on is aiming to apply for the LEED 2009 EB: O&M certification. It is a 275,000 sq.m. retail mall that is currently in operation. Slight renovations have been planned for the current M&E systems, and there will be a newly constructed extension to the building which is approximately 19% of the building’s existing square footage. And the existing building has been operated, and has energy records for over 10 years. My question is about the start date for tracking performance period of the 12 months for the EA credits. Is it required that we have to wait until the new extension has been fully constructed to begin tracking the energy performance period, or we can start once renovations of the existing building (which is the main building) have been completed? Provided we have performance tracking has to be done after construction of the new extension is completed, in any case can we start tracking the performance period prior to construction completion? For example, can we make use of the energy records of the existing building (the main building) as a reference? Thank you. Any comments or suggestions will be very much appreciated.

Hi Alizara, If you're going to include the addition in the certification application, you would have to wait until that addition was completed and operating like normal prior to beginning the 12 month performance period for EAp2. Otherwise, your energy use would be artificially low if accounting for the addition floor area but not its energy usage. You might take a look at the Minimum Program Requirement guidance to see if there is a possibility to exclude the addition from the application. In that case you might be able to start the performance period earlier.
