Indoor Air Quality Control after the COVID-19 Pandemic
|April 22, 2022
The COVID-19 pandemic has focused attention on the role of indoor environmental controls in infectious disease transmission the airborne/aerosol route. This presentation will consider how well existing building systems protect occupants from airborne infectious diseases, how enhanced controls can reduce risk of transmission, and how building design and operation need to change in the future to reduce the impact of future pandemics. Knowledge gaps and research priorities will be discussed as well as the importance of connecting infection risk mitigation with higher goals for indoor air quality generally to promote health and productivity sustainably. Barriers to change will also be noted and discussed.
