FAQs about EAc1 :

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?

Tracking energy consumption through the performance period

I understand the 12 mos tracking time period can start before the performance period begins but it must also include the performance period. What if your project's performance period is longer than the minimum 3 months, are you required to input energy data into Energy Star Portfolio for the entire performance period? My project's performance period is 7 months so I'm wondering if I'm required to only track the minimum 3 months or will I be required to track the full 7? Thanks.

I actually found out the same project above earned an ENERGY STAR rating of 88 for a 12 mos time period ending August 31,2010. Since Aug 31st 2010 is less than a year from the application date (July 1st 2011), this project is eligible to select "streamlined path" on the LEED online form. Therefore, when I fill out the performance period start and finish date, do I enter the 12 mos time period from the ENERGY STAR label certification form? The documented performance period for this project does not begin until October 1 2010 and ends April 30th 2011. So, technically the ENERGY STAR label does not represent the building's energy consumption during "LEED's performance period". I'm a little confused about LEED's requirements for this situation, can anyone clarify this for me. thanks.

Hi You are correct that if you are submitting with the streamlined path, the label must have been awarded within one year of the LEED application data. The date the label was awarded is the date on the award letter from Energy Star. The LEED application date is the Submit Review Date on the Timeline tab on LEED Online. As for the performance period, when using the streamlined option, the performance period doesn't really matter because it takes a back seat to the other timing considerations listed above. Hannah
