Frequently Asked Questions

On average, a single modern fume hood wastes $1,100+ in energy annually from being left open, and can use more energy than 4 residential homes every day.
Large laboratory organizations can waste $1M+ USD of energy annually from lab users forgetting to Shut the Sash.
Closing hoods promotes lab safety, by reducing the risk of hazardous gases flowing back into the lab (gaseous re-entrainment).
Modern fume hoods reduce the amount of air flowing through them when they are closed; these hoods are called “variable-air-volume” or VAV hoods. Shutting the sash of VAV hoods can save the equivalent of one household of energy daily.
Leading life science organizations invest in sash management solutions to reduce energy consumption and keep their lab users safe. Shutting the Sash of a single fume hood saves an average of 2.0 metric tons of CO2e annually.

Alarms are behavioral change tools that help lab users remember to Shut the Sash after they’re done working at fume hoods.
Alarms plug into the outlet on the front of hoods and are programmed to beep softly when a hood is left open and unattended for several minutes. Alarms will continue to beep until either motion is detected in front of the hood, or the hood’s sash is closed.
Alarms don’t interact with internal hood systems and may be unplugged temporarily as needed to access their outlet.
