The use of chemical and biological agents often requires a laboratory fume hood for conducting experiments and storage of dangerous materials. You will find these hoods in facilities ranging from research centers to hospitals and schools. Controlling these laboratory areas is a challenge, since proper control needs to focus on protecting the lab occupants as well as those in adjacent spaces. Labs may also have specific requirements for temperature and humidity that need to be maintained. While all of this is challenging, it is even more complicated to do it in a manner that is reliable and as energy-efficient as possible.
