A Building Management System (BMS) is a computer-based system that helps to control and monitor the operations of a building. It is used to manage the various services and systems within a building, such as heating, ventilation, air conditioning, lighting, security, and fire safety. The BMS is designed to improve the efficiency and safety of the building, while reducing energy consumption and costs. The BMS is typically connected to a variety of sensors and controllers throughout the building, which allow it to monitor and control the various systems. It can also be used to provide real-time information about the building’s performance, such as energy consumption, temperature, and humidity. The BMS can also be used to automate certain tasks, such as scheduling maintenance or controlling the lighting. In short, the BMS is an important tool for managing and optimizing the operations of a building.
