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

Energy Star Portafolio Manager Tool score

I'm working on a existing office building that is intended to pursue LEED EB:OM certification. Based on preliminary assumptions I'm afraid it wouldn't be able to achieve the 69 score necessary to comply with the prerequisite. If my resulting score is below 69, what should I do to certify this building?. Should I implement energy efficiency measures and wait a year to justify those measures with energy bills? or Should I implement the measures and justify the energy efficiency with path 2? What is the correct path to follow in this scenario? Thanks!.

You don't need to wait a year to see the impact of the energy efficiency measures you implement - your Portfolio Manager score should start to rise as your efficiency improves. To get the full impact you would need to wait a year - how long it will take to get to 69 depends on where you are now and how much of an impact you can make. That said, I would look at path 2 as well to see which produced results faster (and more points for EAc1).

Michael is absolutely right about the score rising over time as efficiency improves, and that process may take less than a year (to surpass 69). However, Cases 1 and 2 shouldn't be viewed as 'options' from which you can select the more favorable route - if your building is indeed an office building, and therefore rateable in Energy Star, you are required to use Case 1. Case 2 is only for non-rateable building types and can't be substituted. Hope that clarifies things a bit. Dan
