What is the definition of a Building Management System (BMS)? A BMS is an automated control system that helps to manage, monitor and optimize the performance of a building’s mechanical, electrical, and HVAC systems. It is used to control and manage a building’s energy efficiency, temperature, lighting, ventilation, and other environmental parameters. It typically consists of a control console and a network of sensors and controllers connected to the systems throughout the building. The BMS is designed to make sure that all systems operate within their optimum parameters, while using the least amount of energy. It can also be used to monitor and track energy use, maintain and schedule mainmaintenance and repair, and provide access control. By using the BMS, a building can reduce its energy consumption, cost, and carbon footprint. In addition, the BMS can also be used to increase occupant comfort and safety, and be integrated with other systems such as security, lighting, and fire systems. By
