Building Management System (BMS) is a computer-based control system installed in buildings that controls and monitors the building’s mechanical and electrical equipment such as ventilation, lighting, power systems, fire systems, and security systems. The main purpose of a BMS is to keep equipment running efficiently and ensure the comfort, safety, and productivity of building occupants. The system can be used to monitor energy usage and optimize building operations, leading to energy and cost savings. Additionally, the BMS can alert building occupants and staff to any safety issues that may arise.
