I am modelling a hotel project. After assigning the residential zones (bedrooms + access corridors) to System 1 – PTAC, there is approx. 6,700 ft2 of conditioned floor area remaining which primarily consists of ground floor reception, restaurant, lounge etc. Do I re-enter Table G3.1.1A so that would mean the remaining zones are assigned to a System 3 PSZ AC system (<25,000 ft2), or since the non-predominant condition is less than 20,000 ft2, System 1 would apply to all zones? It just seems like a System 3 is more appropriate for these space types as there is a dedicated AHU serving these areas in the proposed design.

Thanks in advance for your assistance.
