BACnet (Building Automation Control Network) is an ASHRAE and ANSI standard protocol for achieving interoperability in building systems. Non-proprietary interoperability provides flexibility for the design and configuration of systems and promotes competitive bidding. BACnet is ideal for use with medium to large-sized systems in multi-building sites to implement integration with central plant equipment, and for integration between different building systems. BACnet was developed by ASHRAE with the cooperation of almost every major manufacturer of building automation and control equipment.
The BACnet Manufacturers Association is an organization formed to encourage the successful use of BACnet in building automation and control systems through interoperability testing, educational programs, and promotional activities. BMA membership is open and includes companies involved in the design, manufacturing, installation, commissioning, and maintenance of control equipment that uses BACnet for communications.
