[Bldg-sim] Modeling fume hood exhausts

[Sami, Vikram]

I think that depends on the total volume of exhaust. I don't have it in front of me, but I think if your exhaust is more than a certain amount you have to have either energy recovery to fifty percent or vav flow.

Can anyone tell me when modeling a lab system with fume hoods as to whether the baseline systems are to be modeled as constant volume?

(subsequent alternatives will have variable volume fume hoods).
