CINCINNATI, OH — The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) approved a new approach for specifying interoperable BACnet® building automation and control systems at its 2001 Summer Meeting, held here recently.
Part of addendum d to ASHRAE/ANSI Standard 135-1995, “BACnet — A Data Communication Protocol for Building Automation and Control Networks,” the new approach is based on the use of BACnet interoperability building blocks (BIBBs). Each BIBB defines a small portion of BACnet functionality that is needed to perform a particular task, according to Steven Bushby, chairman of the ASHRAE BACnet committee.
