Building Automation

Building Automation Systems (BAS), also known as Building Management Systems or Building Control Systems, are networks of interconnected devices that manage HVAC, electrical, and mechanical systems in a building. By utilizing Bluetooth and internet connectivity, these systems synchronize devices to enable seamless control. BAS allows facility managers to efficiently monitor and control various electronic and mechanical systems, enhancing energy efficiency and operational effectiveness throughout the building.
