About BACnet
The BACnet protocol is comprehensive in scope and complex in detail. Built upon an international standards base, it has undergone extensive revisions to accommodate solicited and unsolicited structural ideas from all sectors of our industry.
As intricate as it is, however, BACnet's design readily permits future modifications by ASHRAE as building automation requirements change. As our industry embraces this significant and positive development in building automation, we look forward to serving our customers with even better choices and higher levels of quality facility management. BACnet opens the door to true systems integration.
BACnet Information and Resources
BACnet is the term commonly used to refer to the ANSI/ASHRAE Standard 135-2001, adopted and supported by the American National Standards Institute (ANSI) and the American Society of Heating Refrigeration and Air-Conditioning Engineers (ASHRAE).
BACnet stands for Building Automation and Control network. BACnet is a true, non-proprietary, open protocol communication standard conceived by a consortium of building management, system users and manufacturers.
