Radiant and Ceiling Fans
The Golden Gate ASHRAE Chapter has been closely monitoring the COVID-19 situation throughout our area. We place our members’ health and well-being as the highest priority to our local organization. After much consideration, we have decided to cancel our March meeting. We have carefully listened to our local health department and authorities and feel this is the appropriate response.
Please be safe, wash your hands and we will see you in April.

Fred S. Bauman, P.E., FASHRAE, is a Project Scientist with the Center for the Built Environment (CBE) at UC Berkeley. Fred leads research on advanced low-energy HVAC systems, such as radiant, underfloor air distribution (UFAD), displacement ventilation (DV), and personal comfort systems (PCS). Fred was the Principal Investigator for a $3M, four-year research program on radiant systems funded by California’s EPIC Grant Program that recently concluded in April 2019. He has written more than 60 technical articles and was the author of the first UFAD Design Guide, published by ASHRAE in 2003.
Paul Raftery, Ph.D., is a Professional Researcher at the Center for the Built Environment at UC Berkeley. He holds a PhD in Engineering for developing a new method for calibrating building energy models to detailed measured data. He has over a decade of hands-on experience in HVAC engineering, building automation systems and controls, full-scale laboratory experiments, field testing of HVAC equipment, and new technology development. He is a Fulbright Fellow and an active member of ASHRAE - secretary and voting member of ASHRAE TC 6.5 (Radiant heating and cooling) and ASHRAE GPC 36 (High performance control sequences). He has recently completed two California Energy Commission research projects: a $3M (4-year) project focused on radiant hydronic systems, and a $2M (3-year) project focused on smart ceiling fans.
Fred’s presentation will summarize new insights, reports, case studies and design tools that came out of the recently completed EPIC-funded research project, entitled “Optimizing Radiant Systems for Energy Efficiency and Comfort.” Key findings that will be presented include energy and thermal comfort performance, selected full-scale laboratory experiments, controls intervention field studies of two existing high thermal mass radiant buildings, a new radiant design tool, and other resources from the project.
Paul will present the outcomes of a recent California Energy Commission funded research project on ceiling fans. Over the 2 year study period, we measured an average of 39% lower compressor electricity consumption after installing 99 smart ceiling fans in a range of different space types - offices, common areas, cafeterias, and homes - in the California Central Valley. The presentation will also discuss the findings from full-scale laboratory tests where we varied fan model, diameter, speed, room size and height, and present a new publicly available web tool for designing spaces with ceiling fans. This tool simplifies the design process and allows designers to quickly and easily estimate the range of air speeds that a selected fan will achieve in a given room.
