A Building Automation System (BAS) is a centralized control system that monitors and automatically manages equipment and services inside a building. It can connect heating and cooling systems, ventilation, lighting, access controls, sensors, and other building equipment, allowing them to operate according to programmed conditions. Sensors provide information such as temperature, occupancy, and air quality, while controllers use that data to adjust connected equipment.
BAS technology is commonly used in offices, hospitals, hotels, campuses, and industrial facilities. For example, an occupancy sensor can signal the system to reduce lighting or adjust room temperature when an area is unoccupied. This coordinated control helps maintain indoor conditions while reducing unnecessary energy use.
