Ventilate What the Space Actually Needs

Traditional ventilation supplies full fresh air 24/7 regardless of occupancy.

Our DCV systems use CO₂ concentration and occupancy sensor data to continuously modulate airflow via VFDs and motorised dampers — all over BACnet, integrated into the building BMS dashboard.

4-Parameter Air Quality Intelligence

A single multi-parameter sensor gives facility teams the data to ventilate intelligently — not reactively. Real-time dashboards replace daily IAQ patrol rounds.

Frequently Asked Questions

What is Demand Controlled Ventilation (DCV)?

DCV is a ventilation strategy that adjusts fresh air supply based on actual occupancy and air quality rather than running at a fixed rate. CO₂ or occupancy sensors detect when a space is occupied and signal the BMS or DDC controller to increase fresh air. When the space is empty, fresh air is reduced to minimum code levels. This avoids over-ventilating unoccupied spaces.

What energy outcome can I expect from DCV?

Energy outcomes from DCV depend on building occupancy patterns, existing ventilation setpoints, HVAC equipment condition, control strategy design, and commissioning quality. Intellicon does not quote fixed energy savings figures. An indicative assessment can be provided after a site survey and review of existing mechanical drawings.

Which UAE codes or standards does DCV need to comply with?

In the UAE, ventilation design typically references Dubai Municipality guidelines, ASHRAE 62.1, and the project-specific mechanical specification. DCV system design is subject to mechanical consultant review and authority approval as part of the MEP permit process. Intellicon works within the approved mechanical design — final compliance is confirmed by the mechanical engineer of record.

What sensors are used for DCV and IAQ monitoring?

Intellicon typically uses CO₂ sensors (ppm), combined CO₂/humidity sensors, VOC (Total Volatile Organic Compound) sensors, PM2.5 particulate sensors, and occupancy sensors depending on the application. Sensor types and locations are confirmed with the mechanical consultant during design review.

Can DCV be added to an existing BMS?

Yes, in most cases. DCV can be integrated with existing BMS platforms via BACnet or Modbus. Protocol compatibility, available I/O points, and controller capacity are confirmed during a site survey and point-list review before any work is committed.
