FAQs about EAp2 :

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?

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?

EBOM-2009 EAp2:Minimum Energy Efficiency Performance

Using Portfolio Manager: area to consider

We are experiencing difficulties in acquiring a coherent rating from Portfolio Manager for a Hospital in São Paulo, Brazil. As we input all the data, PM is giving us a rate of 100, which does not make sense for this particular project. We suspect that it has to do with the occupied areas. Should we factor in bathrooms, staircases, hallways and elevators in the total area of the Hospital? Or PM works with the pure and simple gross area of the facility?

It sounds like maybe it is an area issue if you are only including the regularly occupied areas. Here is the rule on area measurements, as well as the link the Licensed Profession Guide to Energy Star (which is were the below came from): "The user-entered value for area must be the gross total area of the building. This value is measured from the principal exterior surfaces of the enclosing fixed walls and includes all supporting functions such as kitchens and break rooms used by staff, storage areas, administrative areas, elevators, stairwells, atria, vent shafts, etc. Additionally, the following must be noted: - Existing atriums should only include the base floor area that they occupy. - Interstitial (plenum) space between floors should not be included in total. - Gross floor area is not the same as leasable space. Leasable space is a subset of a building‟s gross floor area. www.energystar.gov/ia/business/evaluate.../pm_lp_guide.pdf
