What is the safest way to heat and cool our spaces during this pandemic? Should we be using fans? Is there any benefit to opening the windows? Are we putting folks in danger by using our HVAC systems? To help answer such questions, this webinar features William P. Bahnfleth who is a professor of architectural engineering at Penn State University. His research interests cover a wide variety of indoor environmental control topics including protection of building occupants from indoor bioaerosol releases. Bahnfleth currently serves as chair of the Epidemic Task Force for the American Society of Heating, Refrigerating and Air-Conditioning Engineers.
