Building energy management and control systems (BEMCS) are designed to monitor, control, and optimize energy use within a building. BEMCS include both hardware and software components. They rely on sensors and metering devices, controllers, and communication networks within the building, and a user interface to reduce energy consumption. A BEMCS helps building operators understand where energy is being used, wasted, and what can be done to improve performance. By incorporating BEMCS with existing building systems, organizations can reduce their energy use by 10–25% and enhance operational efficiency.
