10 Demand-Controlled Solutions

CO₂ + occupancy sensors modulate airflow via VFD and motorised dampers over BACnet — ventilating only what the space actually needs. Fan energy follows occupancy. Live IAQ alerts support manual patrol rounds.

Variable frequency drives are among the strongest energy measures in mechanical rooms. For fans and pumps, power falls with the cube of speed, so at 80% speed the ideal power is about 51% of full load. BMS integration adds predictive failure alerts on motor current and run hours.

10-year battery pulse readers transmit sub-meter data wirelessly. BACnet gateway integration feeds live dashboards for tenant billing, leak alerts, and OPEX benchmarking. No cabling required.

CO₂, PM2.5, TVOC, and RH in one sensor. BACnet/Modbus integration feeds cloud-based alert platforms. Critical for mosques and prayer halls with unpredictable peak occupancy.

Machine learning on BMS trend data predicts equipment failure before it occurs — vibration signatures, runtime hours, temperature deltas. Layered onto existing controllers via BACnet, no system replacement needed.

LoRaWAN point sensors and linear rope sensors detect moisture instantly — triggering SMS + BMS alarms and automatic valve shut-off where actuators are installed. Every event timestamped and logged.

CO sensor-driven fan control with fire alarm integration and automatic purge logic. Fans run only when CO levels require it — at proportional VFD speed. Purge cycles logged for authority inspection.

Occupancy-based and schedule-driven motorised dampers serve conditioned air only where and when needed. Meeting rooms, hotel corridors, and prayer halls are served only during occupancy.

DEWA-compatible signals received at BMS level automatically shed non-critical loads during peak grid events — lighting in empty zones, AHU setpoint relaxation, chiller staging — without disrupting occupants.

Occupancy counters, dispenser level sensors, and odour/NH₃ sensors feed a centralised dashboard alerting cleaning teams only when and where needed. Phantom flush monitoring for water savings.
