A Building Energy Management System (BEMS) is a computer-based control system that monitors and manages a building’s mechanical and electrical infrastructure — including ventilation, lighting, power, heating, and cooling — to optimise performance and energy efficiency.

​

ACal Technologies has over 30 years of experience designing, installing, and maintaining BEMS solutions. We work with open-protocol technologies including BACnet, LonWorks, and Modbus, ensuring our systems integrate seamlessly with your existing infrastructure.
