Minimum % Reduction for Historical Data - Case 2?

We see there are EAc1 points associated with reducing energy consumption as compared to historical building energy usage data for Case 2 projects that can't earn the Energy Star label, but it's unclear what the threshold is for these projects to earn EAp2. Is it just ANY percentage reduction over the past 3 years, or is there a minimum performance threshold? The reference guide is ambiguous.

Thanks!

Hi Kim!! It depends which option of Case 2 you want to go with. Have you benchmarked using the EA Prerequisite 2 / Credit 1 Case 2 Calculator yet? This should give you the answer you are looking for and even other options depending on the path you choose and more importantly the path that will benefit you the most in terms of points

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?
