This week we welcome back Dr. William Bahnfleth to discuss ASHRAE Standard 241-2023 Control of Infectious Aerosols and the future of IAQ standards after COVID.
William Bahnfleth is a professor of architectural engineering at the Pennsylvania State University. He has held previous positions as a principle investigator at the US Army Construction Research Laboratories and as a senior consultant for ZBA, Inc. He holds a PhD in mechanical engineering from the University of Illinois and is a Registered Professional Engineer. At Penn State, Dr. Bahnfleth teaches courses on HVAC system design and indoor air quality. His research focuses on systems for sustainable management of indoor air quality with engineering controls, especially control of infectious aerosols. He is the author or co-author of nearly 200 peer-reviewed publications and 14 books/chapters. He is a past president of the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) and vice-president of the Indoor Environmental Quality Global Alliance.
Dr. Bahnfleth was chair of the ASHRAE Epidemic Task Force and currently chairs the project committee for ASHRAE Standard 241 Control of Infectious Aerosols. Dr. Bahnfleth is a fellow of ASHRAE, the American Society of Mechanical Engineers (ASME), and the International Society for Indoor Air Quality and Climate (ISIAQ). Among his ASHRAE awards are the Louise and Bill Holladay Distinguished Fellow Award, the Donald Bahnfleth Environmental Health Award, and ASHRAE’s highest honor, the F. Paul Anderson Award. He is also a recipient of the Penn State Engineering Alumni Society World Class Engineering Faculty Award, and is a distinguished alumnus of the University of Illinois Department of Mechanical Science and Engineering.
