In what year was the first version of the BACnet standard published?

The first version of the BACnet standard was indeed published in 1995. BACnet, which stands for Building Automation and Control Network, is a communication protocol designed specifically for building automation and control systems. The standard was developed to allow diverse components from different manufacturers to communicate within a building automation system.

The significance of the 1995 publication is that it marked the official establishment of a unified standard for interoperability among equipment, enabling the seamless integration of various systems such as heating, ventilation, air conditioning (HVAC), lighting, security, and fire detection. This laid the groundwork for future developments and adaptations in building management technologies, fostering innovation and enhancing efficiency across many sectors in the years that followed.
