ASHRAE President

William P. “Bill” Bahnfleth, Ph.D., P.E., Fellow ASHRAE, ASME Fellow, is a professor of Architectural Engineering and director of the Indoor Environment Center at The Pennsylvania State University, University Park, Pa.

As ASHRAE’s president, Bahnfleth chairs the Society’s Board of Directors and Executive Committee.

Bahnfleth’s Presidential Theme, “Shaping the Next,” focuses on embracing our responsibility to “Our World” – fellow humans and the earth, to make buildings safe, healthy, productive, comfortable environments in harmony with nature. To do this, he believes we must develop “Ourselves” – the human resource of the professional community, and transform “Our Work” – what we do, how we do it, and who we do it with, by becoming more global in outlook, broader in scope, and more collaborative in approach.

Bahnfleth is the son of ASHRAE Presidential Member Donald R. Bahnfleth, Fellow ASHRAE, Life Member, who served as president in 1985-86. This marks the first father/son presidency in ASHRAE’s history.

He has conducted research on a diverse range of topics including ground-coupled heat transfer, variable primary flow chilled water systems, performance measurement of stratified chilled water storage tanks, optimization of diffusers for chilled water storage tanks, measurement of envelope air leakage of tall buildings, ultraviolet germicidal irradiation (UVGI) for air and surface disinfection in HVAC systems, user-friendly multizone airflow and contaminant dispersion models, metrics for predicting the impact of measures to mitigate risk from airborne indoor contaminant releases, and others.  He is the author of more than 125 articles and technical papers and author or reviser of 12 books/book chapters.

In his ASHRAE service, Bahnfleth is faculty advisor to the Pennsylvania State University – University Park Student Branch, and is an ASHRAE Distinguished Lecturer. He has chaired ASHRAE’s Technology Council, Members Council, Technical Activities Committee and Technical Committee 6.9 Thermal Storage, among others. He has served as a member of numerous committees, including recent appointments to the CLIMA 2013 Advisory Committee, the Building Performance Alliance Ad Hoc Committee, and the Building Safety and Security Position Document Committee.

Bahnfleth was awarded both a Bachelor (1979) and Master (1980) of Science degree in mechanical engineering; a Bachelor of Music (1988) in pipe organ performance; and a doctorate in mechanical engineering (1989) from the University of Illinois at Urbana-Champaign.
