A Building Management System (BMS), known as a Building Automation System (BAS) or Building Control System (BCS), is an integrated solution overseeing a building's mechanical, electrical, security, and other systems. It ensures efficient, reliable, and coordinated operations by controlling and monitoring these systems. The BMS/BAS/BCS optimizes functionality, streamlines processes, and enhances energy efficiency, enabling centralized management for improved performance and maintenance across diverse building functionalities.
