Hello all,

I am using eQuest to model an unconditioned warehouse with conditioned office space in one corner. The warehouse has 40 ft high ceilings. The office space has 10 ft high ceilings, above which is a mezzanine that includes the remaining 30ft (and opens up to the rest of the warehouse). Only the office space is conditioned. I have modeled the whole building as one shell with the office corner as a separate zone.
I can add and remove interior walls in the detailed interface until the geometry is right, but then I don't know how to designate the "lower" space as conditioned and the mezzanine space as unconditioned.
My question is; Have I taken the right approach to modeling this situation? And how can condition the office and not the mezzanine?
Should I use 3 different shells (warehouse, office, and mezzanine)? I don't think I want a 30ft plenum.
Any advice would be very helpful.
Thanks,

Duke Graham
