Our project is an office building with 300 regular occupants. One zone/occupancy category of the building is a multi-purpose room. This room is rarely used - only if there are gatherings or occasions. Also, adjacent rooms are cafeteria, fitness room, game room (rooms that occupants are considered transients). And the people that will occupy those spaces will be the same regular occupants of the building, and will definitely not occupy all those spaces simultaneously. How do we account for the population diversity on the required calculation to verify compliance given that for a whole month operation, this space only used twice or thrice and only for three to four hours?
