BACnet Pioneer Dies

Former BACnet committee chairman and long-time Alerton building-standards engineer William “BACnet Bill” Swan died June 4 at John Muir Medical Center in Concord, Calif.

Swan was instrumental in the development and adoption of ANSI/ASHRAE Standard 135, BACnet - A Data Communication Protocol for Building Automation and Control Networks, which provides mechanisms by which computerized equipment can exchange information regardless of building service. He was a prolific author of white papers and articles, including for HPAC Engineering, and a highly sought speaker for BACnet meetings and other events.

“Bill had a truly global vision when it came to evangelizing the BACnet standard,” Alex Radovan, general manager for Alerton and Trend Control Systems, said. “If he wasn't in the BAC Cave in Redmond (Wash.), he was jetting out for industry events in Berlin or Bangalore or Beijing.”
