This diverse group of essays considers a variety of technology issues impacting IAQ and the associated energy use and emissions--use of outdoor air to dilute contaminants, control of unintended airflows in buildings, use of air treatment technologies like filtration and ultraviolet germicidal irradiation to control particulates and bioaerosols, and reduction of indoor contaminant levels through material selection.
Ultraviolet germicidal irradiation (UVGI) uses 254 nm ultraviolet radiation from low-pressure mercury discharge lamps to reduce the indoor concentration of airborne microorganisms in order to reduce the risk of disease transmission.
