EBOM-2009 EAp2: Minimum Energy Efficiency Performance
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?

Our building includes a large laboratory space. Can our project benchmark under the Labs21 program?
How long is an Energy Star label valid to use with a streamlined approach for Case 1?
When is it possible to exclude up to 10% of the building from EAp2?
How do I account for computers with multiple monitors on Portfolio Manager?

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.
