A BMS (Building Management System) — also known as a Building Automation System (BAS) — is a computer-based control system that monitors and manages a building's mechanical and electrical equipment, including HVAC, lighting, power, and security systems. BMS engineers specialise in programming, commissioning, fault finding, and integrating these systems to optimise energy efficiency and occupant comfort. Common work includes controller programming, sensor calibration, graphical interface development, and integrating HVAC plant with the BMS. HVACX is a marketplace — we connect you with independent BMS engineers who carry out the work. We do not perform BMS engineering ourselves.
