Approaches for disinfecting occupied rooms efficiently and safely with UV light

A new study published in
Indoor Air provides design-based solutions on how to best use ultraviolet germicidal irradiation (UVGI) to disinfect occupied rooms without harming individuals. This research was conducted by Dorit Aviv, assistant professor of architecture and director of the Thermal Architecture Lab at the University of Pennsylvania Stuart Weitzman School of Design, Penn visiting scholar Miaomiao Hou, and Jovan Pantelic, an air quality expert at Katholieke Universiteit Leuven.
Ultraviolet germicidal irradiation (UVGI) devices use short-wavelength ultraviolet light to inactivate viruses, bacteria, and other pathogens by destroying their DNA or RNA. UV light is highly effective and has long been used to clean air and surfaces, with increased uptake in settings such as subway cars during the pandemic. However, UV light can also damage skin and eyes and must be used cautiously in occupied spaces.
