The objective of safe and efficient laboratory hoods can be improved by finding an alternative that does not rely on face velocity to calculate the volumetric flow of air through a fume hood
Similarly, labs driven by their fume hood
usage can be further reviewed to determine if sashes are properly managed (an occupant behavior program), or to consider implementation of a more efficient fume hood
strategy (an equipment/controls-focused program).

Choosing architects without this knowledge has resulted in expensive building mistakes that seem almost comical after the fact, like the builder who wanted to put a restaurant-style fume hood
in a high school chemistry lab.
