The author suggests that using Standard 62.1 can provide for excellent laboratory IAQ and result in significant energy savings. Standard 62.1 can be a good baseline for the energy consumption of individual lab spaces as well as the entire building. An additional advantage is that these methods are not expensive and can be applied to existing as well as new laboratories. Of course, maintaining control over the space contaminants should be the primary goal of the laboratory environment but other guidelines, i.e., Standard 62.1 can be equally as valuable in the occupied spaces of a research laboratory.
