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

Energy Requirements - Looking Ahead to EBOM 2012

We are working on a retail/catering facility that we cannot currently certify as NC because the addition we are doing is not large enough to qualify. However we cannot go for EBOM certification right now because the renovation is too big to qualify. We would like to certify the building in a few years under EBOM once the renovation is done and we can qualify. Right now we are trying to calculate what the energy requirements will be for the EBOM 2012 version for our building, so that we can design within those guidelines to facilitate certification. The 2012 version offers 3 pathways for energy calcs, but I don't think we qualify for any. 1. Energy Star Score - we are not elegible for a score due to our mix of space typologies. 2. Benchmark again Typical Building - The DOE websites says that due to budget cuts they are not doing the CBEC Survery this year. Can we use an old survey? 3. Demonstrate Energy Efficiency - This would require us to wait three years after construction of the renovation. Not only that, it would require us to show a 20% energy improvement over that time period. This creates a weird incentive to design the building really inefficiently so we can show progress - not something we are interested in proposing to the client. Any thoughts, we are at a loss as to what sort of energy intensity standard we should be shooting for... Thanks,

Hello Prudence: My first suggestion here is that you confirm your project is unable to certify now in either NC or EBOM because of renovation / addition activity. That would be unusual, as LEED v2009 does not intend to exclude projects in your situation. Have you reviewed the current MPR guidance and rating system selection guidance to be sure? If you stick with v2012 then I recommend Option 2. The reason is simple: Option 1 references ENERGY STAR, which in turn references the "current" CBECS data, which happens to date back to 2003. Option 2 in v2009 also ultimately references the 2003 CBECS. If CBECS is not updated soon then LEED will have little choice but to continue referencing the same CBECS version it does now, i.e., the 2003 data. I would expect this to apply to both Option 1 and Option 2 in LEED 2012. So, although there are no guarantees, I believe your safest bet is to stick with #2, and select an EUI target relative to CBECS 2003.
