Internal Pressure Coefficient (AS/NZS 1170)

I have a bit of confusion regarding the rules stated in the AS/NZS 1170 Section 5 on determining the internal pressure coefficient. I am wondering, is the Cpi determined from the table 5.1(A) or 5.1(B) for the whole building? Or is it only used as the Cpi on one surface?
