Building Control Systems

BuildingAutomation Systems

Building control systems – also called Building Automation Systems (BAS), Building Automation and Control Systems (BACS), or Building Control System (BCS) – have quickly become vital in maximizing efficiency, sustainability, and profitability in today’s buildings. These systems integrate HVAC controls with a building’s lighting, security, and other features, essentially creating a “smart” building.
