About

Dr. Bahnfleth holds BS, MS, and PhD degrees in Mechanical Engineering from the University of Illinois at Urbana-Champaign. He is a professor of Architectural Engineering at Penn State, where he also directs the Indoor Environment Center. Prior to joining the Penn State faculty, he was employed as a consulting engineer and as a researcher at the U.S. Army Corps of Engineers Construction Engineering Research Laboratory.

He is a Registered Professional Engineer whose practice is primarily in the area of chilled water systems, with particular emphasis on the application of stratified chilled water storage. He has participated in master planning and chilled water plant design exercises for universities, manufacturing facilities and medical centers throughout the Midwest and eastern United States and has designed and commissioned chilled water storage systems in the U.S. Canada, Australia, and Saudi Arabia. He was co-recipient of a 1st place ASHRAE Technology Award for the design of the Cornell University chilled water storage addition.

At Penn State, Dr. Bahnfleth teaches courses in HVAC fundamentals, chilled water system design, heating system design and indoor air quality engineering. His research interests include chilled water plant design and operation, thermal energy storage, indoor air quality and building security.

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 book chapters.

Dr. Bahnfleth is a Fellow and Distinguished Service Award winner of the American Society of Heating, Refrigerating, and Air-Conditioning Engineers. He is a member of several ASHRAE technical and standards committees and has chaired TC 6.9 Thermal Storage. He is also active in ASHRAE governance, currently serving as its President-Elect. He is also a member of the American Society of Mechanical Engineers, the American Society for Engineering Education, and Sigma Xi.
