Did you know that fume hoods operating at full velocity are
responsible for 6% of the total energy use on campus?
You can help conserve energy.
Icahn, Bowen, and New Frick Labs have variable air volume hoods
that adjust the amount of air exhausted based on the height of the
sash. When the sash is closed, face velocity is reduced by 40%.
Closing the sash leads to significant energy conservation.
Consider the energy costs of operating each hood for one year:
Open sash
Closed sash
Bowen
$1775
$110
Icahn/New Frick
$1130
$70
Please conserve energy by closing the sash when the
fume hood is not in use.
