Fume Hood Calculator

Laboratory fume hoods are highly energy-intensive. The typical fume hood in US climates uses 3.5-times as much energy as a home. We have launched a web-based calculator that estimates annual fume hood energy use and costs for user-specified climates and assumptions about operation and equipment efficiencies. The calculator can be used to test the energy and cost impacts of improving component efficiencies (e.g. fans or space conditioning equipment), modifying face velocities, and varying energy prices. Supply air setpoints can be varied, as can the type of reheat energy. Several hundred weather locations around the world are available. The calculator allows for an instantaneous comparison of two scenarios. More information on methodology can be found here.
