BACnet is an open communication protocol for building automation and control systems, including HVAC, lighting, security, and fire detection. Developed by ASHRAE, it enables interoperability between equipment from different manufacturers so systems can share data and operate together. This improves energy efficiency, simplifies management, and supports better comfort and safety.

BACnet links HVAC, lighting, and safety systems for central control.
A building manager uses a BACnet-enabled platform to adjust HVAC and lighting schedules based on occupancy, lowering energy costs while keeping occupants comfortable.
When upgrading building automation, choose BACnet-compatible equipment to keep your system flexible for future expansions.
“When upgrading building automation, choose BACnet-compatible equipment to keep your system flexible for future expansions.”
BACnet became an official ASHRAE standard in 1995 and has since become the most widely used building automation protocol.
Is BACnet only for large buildings?
It is common in commercial buildings, but it can be used in any facility that needs integrated control and monitoring.
Do all devices support BACnet?
No. Devices must be BACnet-enabled or connected through compatible gateways to communicate.
Why is BACnet good for future upgrades?
Its open standard lets you add or replace equipment from different vendors without rebuilding the entire system.
