Expanding BACnet's Horizons



Steven T. Bushby


The International Air-Conditioning, Heating, Refrigerating Exposition that accompanied the 2001 ASHRAE Winter meeting in Atlanta included the largest interoperability demonstration of BACnet products ever held. It marked the five-year anniversary of the first public unveiling of interoperable BACnet products. This article describes how the BACnet standard has evolved and expanded beyond HVAC control, and how it has been received in the market place. Five years after its adoption, the BACnet standard is finally beginning to emerge as a significant market force for HVAC and other building control applications around the world.
