Close Fume Hood sashes - ALWAYS

Problem: Fume hoods draw out warmed or cooled air from your lab 24/7.

Solution: Some hoods are “smart” (a.k.a. variable air volume) and they slow down 60-80% when you close the sash. Even constant volume hoods draw less air when closed, and the sash is safest in its lowest position.

Benefits: You can save anywhere from hundreds to thousands of dollars per year by keeping the sash closed.

Costs: There is no impact on lab operations other than making it safer. This is the easiest and biggest payback item in any lab.
