Setbacks for synthesis labs are a bad idea as the reactions often are run at “room temperature” and dependent on a consistent temperature sue to changes in kinetics if it varies.  Analytical labs often have queues of experiments set up for overnight, and cell experiments/fermentations can have the same issues on open shakers, etc.

Tough to do with labs.  One energy control can be closing hoods or having them set with variable speed settings based on open or closed.

Does anybody do temperature setbacks in research labs when unoccupied – specifically with the use of occupancy sensors?  I know our research labs are occupied at all times and days of the week but curious if anybody has done this with occupancy sensors and how it has worked out.  Thanks!
