Laboratory fume hoods are energy-intensive. They are intended to provide adequate protection for workers conducting experiments or manufacturing activities within the hoods. The typical fume hood in US climates uses 3 to 5 times as much energy as a home. This calculator estimates annual fume hood energy use and costs for user-specified climates and assumptions about operation and equipment efficiencies. To create comparative energy-use scenarios, vary inputs in the Assumptions panel as desired.

The fume hood calculator is sponsored by the U.S. Department of Energy Federal Energy Management Program. This web application was developed by Lawrence Berkeley National Laboratory and Earth Advantage.
