Abstract
A system for controlling a face velocity of a fume hood includes one or more sensors that are configured to detect one or more users in front of the fume hood. A controller is configured to determine a desired ventilation airflow rate for the fume hood based at least in part on the one or more users detected by the one or more sensors, wherein the desired ventilation airflow rate corresponds to one of three more available ventilation airflow rates. The controller is configured to provide a control signal to a ventilation device of the fume hood, wherein the control signal corresponds to the desired face velocity.
