Hello everyone. May I ask 2 questions about this credit?

A) Assuming a project go for option 1. In ASE simulation, we shall demonstrate more than 10% of "regularly occupied floor area that is daylit per the sDA300/50% simulations" could fulfill the ASE requirement according to LEEDv4 reference guide.

May I ask if this area represents (1) All regularly occupied space studied in sDA simulation, or (2) The regularly occupied space studied in sDA simulation that could fulfill sDA 300/50%? This could affect the study area and the overall percentage.

B) May I know the potential reason why perimeter floor area rather than all regularly occupied floor area is accessed healthcare premises?

Many thanks!
