[Bldg-sim] Modeling Fume Hood Exhausts

[Sweitzer]

Other questions -

If you model it as constant volume, do you use full sash height or resticted sash height?

When you model a VAV system, what assumptions do you make about the user's behaviour in closing the hoods, or are you keeping them closed whenever no one is standing in front of them by employing an Automatic Sash Positioning System?

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).
