A Building Management System (BMS) is a computer-based system that is used to monitor and control the mechanical, electrical, and other building systems in a facility. It is designed to optimize the performance of the building’s systems, reduce energy consumption, and provide a comfortable environment for occupants. BMS systems can be used to control lighting, heating, ventilation, air conditioning, fire protection, and security systems. The system also allows for remote monitoring and control of the building’s systems, as well as providing alerts and alarms when something is not functioning correctly. The system can also be used to collect data about the building’s systems, which can be used to identify trends and help improve the efficiency of the building’s systems. BMS systems are becoming increasingly popular as they offer a cost-effective way to manage and maintain a building’s systems.
