Building Automation System involves a combination of multiple building management systems installed in buildings using computer based control system that control and monitoring of a buildings mechanical and electrical equipment such as ventilation, lighting, power systems, fire systems, and security systems. The objectives of building automation are improved occupant comfort, efficient and effective operation of building systems, and reduction in energy consumption and operating costs. Buildings controlled by a BAS is often referred to as a smart building.


Monitoring and support plan under BAS involves centralized monitoring and support of a building’s complete infrastructure. Continuous monitoring enables organization in early detection and scheduled maintenance. Below is the monitoring of the hospital system through a centralized monitoring tool as well as examples of fire and security monitoring, lighting controls, automated electrical switching and monitoring
and operation an automation of mechanical systems.
