Fume Hoods

Although only a few feet tall, a typical laboratory fume hood consumes more energy than three homes — an average of $5,000/year (and up to twice as much in hot climates). The resources below highlight the Berkeley Lab's work on fume hoods including the development of the Berkeley Hood, which cuts exhaust airflow requirements by 50-70%. The Fume Hood Calculator also estimates annual fume hood energy use and costs for user-specified climates and assumptions about operation and equipment efficiencies.

Keeping fume hoods closed is also important as closing a sash at LBNL saves about 3.3 to 4.4 metric tons of CO2 emissions per year (MT CO2/yr). Sustainable Berkeley Lab launched its own Fume Hood Watch program to encourage employees to close all fume hoods when they are not in use.
