Hi, At the University of Washington we have been told to lower the sash all the way when the hood is not in use to save energy and money. I believe there have been several Universities that have done some cost analysis of this and have show large savings in money (one study stated $1500 per year per fume hood in savings and a reduction in 10,600 lbs of CO2 emissions). If you want more information just do a search for "shut the sash". So, if it is not feasible to shut off the hood you can save energy and money just by closing the sash.
Have a great weekend.
