The open protocol standard for computerized building systems: BACnet

BACnet spent nine years under development by a committee drawn from manufacturers, universities, government agencies and consulting firms in an effort to produce a truly open protocol whereby equipment from different manufacturers can interoperate in a complete, integrated building automation control system. The result is a standard that defines all the elements of communication between devices, from the abstract language of objects and services right down to the physical LANs. With its adoption as an ANSI standard and the interest shown world-wide, it is safe to say that BACnet points the way to the future of communication within building automation controls
