Have a S1 use, 13994 square ft., sprinklered (gets it over 903.2.9 15 VCC) and is a PEMB (metal storage facility).
The contractor wants to condition the PEMB (climate control) and is using 2 HVAC single zones to conditon the space and afford protecion from freezing of the sprinlker system.
The problem insofar as the energy code requirements of 2015 VECC/IECC 403.2 & following sections as mandatory, is all the doors are rolled up and are accessible only from the exterior. Don't have the R value of the OHD's but I'm sure it is alot less than what is required for the thermal envelope as called out in table 402.1.3.
In my mind this would be difficult to maintian a conditoned space when roll up doors are wide open and losing all the energy in the building to the outside. Most have burglar wiring several above the stalls, so anything ,everywhere will follow the pressure out the door. I think designating a low energy building would be the way to achieve compliance, otherwise how could it be maintained?
Thoughts anyone.
Thanks in advance
