We are working on a project with two stages. The first stage is a shell building, the second stage is a tenant finish-out.

The HVAC system is part of the tenant finish-out stage. The tenant asks that the shell building be LEED certified. Is it possible to LEED certify a building with no HVAC system? No matter how thick the walls, it won't use any energy! Applied to EA prerequisite 1 - what is there to commission if there is no HVAC?

Since fundamental commissioning is a prerequisite, is this a showstopper?
