As facility managers (fms), consulting and specifying engineers, and other members of the building industry focus more intently on energy consumption and resultant cost, finding ways to reduce product lifecycle and maintenance costs has become an hot topic industry-wide. Effectively integrating building automation systems directly results in lower costs and gained efficiencies. Considering nuances, such as using only one data communications protocol in these efforts, can not only drive these results but other benefits as well.
Developed by the building automation industry for the purpose of building system integration, Building Automation and Control network (or BACnet®)—an open data communications protocol for building automation and control networks—facilitates integration of HVAC, lighting, security, and other commercial building systems. It can work toward enhancing energy savings, lowering design, and lifecycle costs, facilitating commissioning, and providing improved flexibility, scalability, reliability, and control.
BACnet’s ultimate objective is to achieve interoperability of building control devices that may differ by application, manufacturer, and vintage. While there are other open protocols widely used and supported within the building automation industry, BACnet was the first protocol developed by the industry purely for building system integration, and has been widely adopted by manufacturers of building control devices. Therefore, a plentiful and growing supply of BACnet devices virtually guarantees that interoperability can be achieved and maintained now and in the future.
