State of Washington here.
Barn type structure with the lower floor as an A2 or A3 for hosting weddings, gatherings, reunions, and similar assembly functions.
back 1/4 of the barn has a 2nd floor apartment that will be an R1.
Both spaces are heated/conditioned. The building will have automatic fire suppression and a 1 hour floor ceiling between the apartment and the A occupancy below.
Question is this. Does the floor ceiling need to have it's own insulation and it's own thermal envelope or does the fact that the lower portion is conditioned with an envelope that meets or exceeds the requirements of the R1 satisfy the requirements?
I have exhaustively read the Washington energy code as well as the IBC and can't find anything definitive. Thanks in advance for the input.
