10 Demand-Controlled Solutions

CO₂ + occupancy sensors modulate airflow via VFD and motorised dampers over BACnet — ventilating only what the space actually needs. Typical fan energy saving: 20–40%. Manual IAQ patrol rounds replaced by automated alerts.

Variable frequency drives are the highest-ROI single investment in mechanical rooms. At 80% speed a motor uses only 51% energy (cubic law). BMS integration adds predictive failure alerts, cutting reactive maintenance 40%.

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.
