[Equest-users] University building with laboratory exhaust

[Sami, Vikram]

Jeff,
The newer versions of eQUEST have the ability to track exhaust on a zone-by-zone basis (I think this was added specifically for fumehoods). You would use the track exhaust flow option (where it modulates the supply to ramp up from minimum to match exhaust flows). You can assign power numbers to the exhaust fan.

Subject: [Equest-users] University building with laboratory exhaust

Hi All,

I was hoping for a comment on a suitable approach for modeling a university classroom building that has laboratory exhaust fume hoods. Of the three floors, the lab hoods are only about a third of one floor but do have a significant airflow discharge (with make-up). The building is about 50,000 sf.

I plan to develop a schedule for the fume hood fans and apply airflow to the fans and have these be the same for the baseline and proposed cases. Do I simply apply it to the standard exhaust inputs or is there a "lab hood" area in eQUEST I cannot find? Any advice on how to capture and schedule this exhaust would be helpful if this approach is not suitable.

Thanks for all of your help!
