Hi,

I have a 6 floors/2000 m² nonresidential building, and I am not sure about the system it should be. Area or number of floors is more relevant when choosing a system? It could be system 2 or 6 if considering the area, but it would be system 8 if considering its 6 floors, what looks non sense to me!

Another question, do underfloor and technical floors count?

Thank you for your help!
