President's Message

Happy Holidays:

Last month’s past presidents’ meeting was one to remember. We had one of the best turn outs ever for past president’s night. There were 14 past presidents and 39 total attendees. We also had a great presentation on federal incentives and grants by Michael Love plus recognized Frank Ruth with the Chapter Service Award and got to celebrate Carl Courtney’s birthday too.

Our next meeting is one you won’t want to miss. Dr. Bahnfleth, professor of Architectural Engineering at Penn State University will be giving a presentation on thermal storage. Dr. Bahnfleth currently serves as society Vice President, is a Distinguished Lecturer, and is past chair of several technical committees. Don’t miss this excellent opportunity.

I look forward to seeing you all this month.

Cool Thermal Storage in the Era of Sustainability

During the 1980s and 1990s, cool thermal energy storage (TES) was a key technology in US utility demand-side management (DSM) programs. Interest in TES declined steeply as incentives disappeared during utility deregulation. Today, the focus of design has shifted from energy cost savings toward sustainability and it is reasonable to ask whether TES has anything to offer in this environment. This presentation will review the essentials of cool thermal energy storage and examine its relevance to sustainable design. Specific issues examined will include the impact of TES on site and source energy consumption, the economic case for TES without the incentives of the DSM era and the role of TES in achieving net zero energy buildings and communities.

William Bahnfleth is Professor and Director of the Indoor Environment Center in the Department of Architectural Engineering at the Pennsylvania State University (Penn State) in University Park, PA, where he has been employed since 1994. Previously, he was a Senior Consultant for ZBA, Inc. in Cincinnati, OH and a Principal Investigator at the U.S. Army Construction Engineering Research Laboratory in Champaign, IL. He holds BS, MS, and PhD degrees in Mechanical Engineering from the University of Illinois, where he also earned an undergraduate degree in music (pipe organ performance), and is a registered professional engineer.

At Penn State, Dr. Bahnfleth teaches undergraduate courses in HVAC fundamentals and controls and graduate courses in chilled water systems, hot water and steam systems, and indoor air quality. His research interests cover a wide variety of indoor environmental control topics, including chilled water pumping systems, stratified thermal energy storage, protection of building occupants from indoor bioaerosol releases, ultraviolet germicidal irradiation systems, and others. He is the author or co-author of more than 100 technical papers and 11 books and book chapters. He consults regularly on the design of chilled water thermal energy storage systems and has been involved in more than 20 projects world-wide.

Press Release from Task Group 3

Sessions to Boost Efficiency, Sustainability of Contractor Projects Featured at AHR Expo

ATLANTA – Two free sessions to assist contractors in construction management and high-performance buildings are being offered by ASHRAE at the AHR Expo.

“To ensure energy efficient buildings means engineers must work more closely with all members of the building team,” said Billy Austin, chair of ASHRAE’s task group on contractors and design build firms that is sponsoring the sessions. “With contractors representing 25 percent of Expo attendees, this was a good opportunity to reach out by offering sessions on topics of importance to them and the industry.” The sessions, of which are free and require no conference badge, are Construction Management, 2-30 p.m., Monday, Jan. 25, and Cost/Benefit Analysis Methodology and Tools Needed by Owners, 2-3 p.m., Tuesday, Jan. 26. Both take place at the Orange County Convention Center, site of the 2010 AHR Expo, Jan. 25-27, Orlando. The ASHRAE 2010 Winter Conference takes place Jan. 23-27, Rosen Shingle Creek hotel, Orlando. For more information, visit

Construction Management addresses two key contractor-related topics to help improve the quality of their work: will systems commissioning improve the contractor's ability to perform well and preconstruction management basics for the mechanical engineer and contractor on design-build/design-assist projects. Cost/Benefit Analysis Methodology and Tools Needed by Owners provides an understanding of high-performance building cost benefit analysis with a focus on the LEED rating system. Several topics are addressed, including cost/benefit project setup, fiscal metrics, constraints and length of analysis.

Dan Kerr, member Central PA Chapter, is a member of ASHRAE Task Group 3. If you have questions about the AHR Sessions or the activities of Task Group 3, please contact him. (717) 232-9743 or
