Baseline System Type for Hotels

Hi, I am wondering what Baseline System Type should be used for hotels? We have a 11 floor hotel, with the first 3 floors being conference and common areas, and the rest of the floors are hotel guest rooms. In Table G3.1.1.A it is stated that hotel roms are considered as residential spaces. Does that mean that I should model all spaces as System 1/2 or just the guest rooms as System 1/2 and the rest of the spaces as System 7/8? To simplify, can I use System 7 for the whole building - and consider the guest rooms as non-residential? Thanks in advance,

Hotel rooms are residential. You then apply any of the exceptions to G3.1.1 using the remaining area. If none of the exceptions apply then the whole building is a system 1 or 2.

Ok, thank you! About possible exceptions under G3.1.1. I guess that only Exception a) applies. We probably have enough non-residential areas to meet the Exception requirement, however - what determines the System for the non-residential zone. For example, is it the number of floors of the whole building (meaning System 7/8) or the area for the non-residential zones, which might mean System 3/4?

It is what is left over after accounting for the residential portion of the building.
