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

Transferring numbers from EPA Statement of Energy Performance

This question is specifically about taking info from Portfolio Manager and putting into LEED online v.3. My project building is not eligible for Energy Star because it is an office building that is less than 5000 sq.ft. I completed the eligibility tab on the EAp.2 case 2 Calculator and it looks like we fall under Option 1. So I also completed entering energy data for 12 months into Portfolio Manager and printed out the Statement of Energy Performance. Do I then take the number from Statement of Energy Performance under "Energy Intensity" heading for "Source" and put into Section IV of calculator where it asks for "Project Building's annual weather-normalized Source ENergy Use Intensity" or do I use the number listed under "Energy Intensity" heading for "Site"? I can not find an explanation of these numbers on the Portfolio Mgr website. It makes a difference in whether my project complies with pre-req or does not. Thanks!

Rather than using the Statement of Energy Performance, I would set up a new "view" in the Facility Performance area of the building on Portfolio Manager that includes the building's Weather Normalized Source Energy Use Intensity. This value may be slightly different than the one that shows up on the Statement of Energy Performance. Don't use the Site Energy Use Intensity.

Also, it's a good idea to include a screenshot with your submittal documentation highlighting the weather normalized source energy use intensity on Portfolio Manager.

Thank you Ben for information. Unfortunately, using my building's weather normalized source energy intensity for the past year, we do not meet requirements under EAp1 Option 1. We made HVAC change and added insulation mid-year last year, so my only hope is that those changes will result in reduction of energy used as we proceed through this year. If I don't meet minimum requirements using Option 1, am I allowed to use Option 2? If so, do you know of best place to find help with using Option 2.

Janna - I'm pretty sure that you have to stick with Option 1 in this case. Option 2 is only triggered if more than 10% of the space is "All Other - Not Classified" or "Service". Hopefully you can pick up some efficiency with the new changes.
