I would add that whether they would be practical in a particular lab setting will also depend on how the automatic closing is triggered. You don’t want the sash closing on a researcher who is doing or observing in a way that lets the system think no one is there. Just think about the annoyance issues of automated lighting turning off inappropriately.

Hello Kimi Brown!
There are a variety of strategies to save energy on fume hoods. You might try the article I wrote for March ACS Journal of Chemical Health and Safety.
https://pubs.acs.org/doi/10.1021/acs.chas.9b00013
Short answer is sash closers only save energy with a Variable Air Volume System and these systems require large up-front capital outlay. Lots more in the peer-reviewed paper above.

[Cross posting to IH/Lab Safety and ACS DCHAS]
Hello all:
The architect and lab-planner consultants for an energy research building on our campus have recommended the installation of fume hoods with automatic sash closers. Being an energy-research facility, there is obviously a focus on efficiency and sustainability in the design, and this is one of the proposed ways of making the labs greener.
Having no first-hand experience with this these, our office is concerned about the practicality of these in devices in an academic laboratory setting. Does anyone have any hoods like this on their campus?
