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?

EBOM-2009 EAp2:Minimum Energy Efficiency Performance

Data center --IT energy sub meter calibration

Hi, I am involved in EBOM case with a data center. As noted above, basically we do not need calibration since we use data from utility bill. Yet for a data center we have to measure UPS output energy to get rating in energy star. In my case there are meters for UPS, however since this is for 24 hour 365day facility, they cannot perform calibration. Do you have any idea what I can do for this? Thank you,

Shoko, My first thought is to look at when the meters where installed, and determine if they are even due for calibration yet. In some case, meters are designed to no require calibration for very long periods of time, and for LEED you can simply document that per the manufacturers guidelines, no calibration is necessarily.

Jenny, Thank you for your comment. After I sent my question, I found in Energy Metering section of online Form they ask only for "annual site energy usage" and for this amount we do not have to include the data of UPS output. Therefore, I believe we can mark "Energy meters are owned by a third party" not to upload calibration reports, in the case we can use utility bill for the amount of site energy usage, which include IT energy as well. Do you think this is right understanding? Thank you, Shoko

Shoko, I think you have the right approach here.
