A Building Management System (BMS) is a computer-based system that is used to control and monitor the mechanical, electrical, and other systems within a building. It is a system that is designed to optimize the performance of the building, ensuring that it is running at peak efficiency. BMS systems can be used to monitor and control a variety of systems, such as heating, ventilation, air conditioning, lighting, and security. They can also be used to manage energy usage, providing detailed information on how much energy is being used and where it is being used. Additionally, BMS systems can be used to monitor and control access to the building, as well as provide access to data and analytics. BMS systems are an important part of any building, providing a comprehensive view of the building’s operations and helping to ensure that it is running at its best.
