A building management system (BMS) is a computer-based system that monitors and controls various building systems, including HVAC, lighting, security, and fire safety. In HVAC applications, a BMS can optimize system performance, reduce energy consumption, and improve occupant comfort. It can also provide real-time monitoring, alarm notification, and data analytics to facilitate predictive maintenance and energy management. A BMS can integrate with other building systems and devices, enabling a holistic approach to building operations and management.
