1. Sounds like a 4 2. It is based on conditioned space. See the note under Table G3.1.1A

Dear Concern:- As per G3.1.1A we need to select system 8 because our project consist of 6 no of floors but no of A/c spaces and A/c area is very low A/c Area is just 4000 Square feet only and no of A/c spaces are just 5 only so please clarify how the base case system selection done, based on no of floor or no of conditioning floor If we take system 4 as base case means how we justify the base case selection

Baseline system selection is based on the number of CONDITIONED floors, the area and the heating source. If you don't have a heating source you use electric. See G3.1.1 which indicates it is based on CONDITIONED floor area.
