Smart Building Controls (Energy Management Systems)
Buildings contain many different systems that use energy and interact with each other. For example, changes in a lighting system will have a direct impact on the energy used by the building's heating and cooling system.
Energy management control systems use computer-based monitoring systems to optimize these systems and how they work together, and can help minimize energy consumption. They range from simple systems (home setback thermostats, occupancy sensors, or timer-controlled thermostats) to smart buildings that have highly complex levels of automation. These systems integrate monitoring and control of heating and cooling systems, lighting, building envelope shading, elevators, security, fire control systems and many other subsystems.
