[Equest-users] LEED 2009 - Commercial Interiors Energy Model Question

Does anyone have any experience with energy modeling for LEED 2009 Commercial Interiors credit EA1.3 - Optimize Energy Performance?

We have a client that is going to occupy a single floor of a 20 story office building and they are putting new HVAC systems in for that floor. The main AC unit for the floor is a condenser water cooled air handler (commonly referred to as a SWUD unit) that distributes air to VAV boxes. (the rest of the building uses a similar system and uses the condenser water loop for heat rejection)

The LEED manual indicates that the whole building must be modeled, which would almost seem like any savings from the one floor get diluted by what is happening on the others.

Thanks for any insight
