I am working on C & S project wherein 4 AHU's are serving an entire office area per floor. Although we know that a single tenant is occupying entire building, what we do not know is how these 4 AHU's will be ducted in the office, since duct work is under tenant scope of work. So is it possible for the C & S project to submit VRP compliance calculator by adding up all AHU's and assume certain percentage of conditioned area as conference rooms/meeting rooms? Or Do we have to assume office area for each AHU and perform VRP calculations. Please suggest.
