Hello all,

I have a question about occupancy schedules for energy models.

Generally the owner will provide peak occupancy numbers on a room-by-room basis; and a peak overall occupancy number for the entire building. Inevitably the room-by-room numbers will add up to significantly more than the overall building number.

Which numbers should be used for the energy model? Would you use the room-by-room number and scale them down with the occupancy schedule based on the overall occupancy?

Obviously, this has a significant impact on the results.

Thanks,
