A Building Automation System (BAS) in construction is a centralized, intelligent network of hardware and software that monitors and controls a building's mechanical, electrical, and HVAC systems. It automates functions like heating, cooling, ventilation, lighting, and security—improving energy efficiency, occupant comfort, and operational visibility. Modern BAS platforms allow facility managers to monitor real-time data and schedule systems remotely from a single dashboard.
