Laboratories have very strict air flow requirements that you may have never considered before. For example, it is not uncommon for the air in a lab to be exchanged 10 or 20 times per hour. As you might imagine, this results in a tremendous amount of energy consumption. In fact, ventilation systems have been shown to account for nearly half of all energy used in a lab. As an example, a chemical fume hood uses, on average, as much energy as 3.5 households every day.
