AHU serving more than 1 space
If an AHU is serving more than 1 space and these spaces are of different occupancy/usage patterns (ie serving partly an office, a corridor, and an auditorium), how do we input the space assigned to this particular AHU? Do we assume it to be serving the biggest load? or the most used? Or do we enter it once for each of the spaces - how do we account for its capacity for each space in the Ventilation Rate Procedure?

I would enter it for the biggest space, or the space that is most relevant in determining its rate.

Pablo - The 62MZ calculator downloadable from LEED Online lets you account for all the different spaces served by a single AHU. You build up the total OA requirement from the OA required for each of the different space classifications served by that AHU.
