A building management system (BMS) is a centralized control system that monitors and manages a building's various systems, such as heating, ventilation, air conditioning (HVAC), lighting, and security. By integrating these systems, a BMS helps improve energy efficiency, comfort, and safety for occupants. The BMS collects data from sensors and devices throughout the building, allowing facility managers to make informed decisions about maintenance and operations. This technology can also automate processes, reducing the need for manual intervention and ensuring optimal performance of the building's systems.
