We're working on a historic renovation, total gut, but will be left as a cold dark shell - no MEP at all, it will all be in the tenant scope of work. The building is small, around 8,000 sf, and the team will be gutting it, replacing the windows, and likely insulating the roof. What do we need to do to document compliance with the pre-req? Do we need to model it and show that our envelope improvements exceed ASHRAE? Can you apply the ASHRAE design guidelines just to what's in our scope? If so, do the rest of the guidelines have to be in the lease agreement? Thanks!
