A Building Management System (BMS) is a centralized control system that manages a building's mechanical and electrical equipment. This includes systems like heating, ventilation, air conditioning (HVAC), lighting, and security. By integrating these systems, a BMS helps improve energy efficiency, comfort, and safety within the building. BMS technology allows for real-time monitoring and automation, enabling facility managers to optimize operations and reduce costs. It can also provide data analytics to identify trends and maintenance needs. Overall, a BMS plays a crucial role in enhancing the functionality and sustainability of modern buildings.
