A BMS is the control centre for a building. It collects data from sensors and equipment across the site – temperature, occupancy, power consumption, CO2 levels – and uses that data to run the building automatically. When a room is empty, it dims the lights. When CO2 rises, it opens more fresh air.
Modern BMS platforms communicate with field devices via BACnet, Modbus, or KNX. IoT overlay systems – wireless sensors connected through a gateway – feed new data into an existing BMS via these protocols, without replacing anything.
- HVAC control – adjusts heating and cooling based on occupancy and temperature
- Lighting management – dims or switches off lights in unoccupied zones
- Energy monitoring – tracks consumption by floor, zone, or circuit
- Access and security – integrates door sensors and camera feeds
- Fault alerting – notifies facilities teams when equipment behaves abnormally
