Demand Controlled Ventilation (DCV)

The most efficient way to balance indoor air quality and energy savings.

Demand controlled ventilation (DCV) is a process designed to adjust/reprogram the ventilation settings within a building, based on the fluctuating occupancy.
DCV systems can automatically reduce ventilation intensity during off-peak hours, saving a lot of energy in the process. They can also sense if the quality of indoor air is becoming polluted, and fix that by pumping fresh air faster into the building.  

How Does Demand Controlled Ventilation (DCV) Work?

A Demand Controlled Ventilation (DCV) system is equipped with a sensor which detects humidity levels and automatically adjusts the airflow rate based on the indoor air quality. If a room is heavily occupied, the humidity levels will be high – a DCV system will sense this and increase airflow into the room. If a room is unoccupied or humidity levels are low, the ventilation rate is reduced. Similarly, in wet rooms such as bathrooms, when there is an elevated level of humidity and moisture detected, the rate of extraction is boosted to adequately remove the moist, stale air.

What Type of Building is DCV Suitable For?

Demand Controlled Ventilation is suitable for many different property types, including new or existing homes, offices, gyms, healthcare premises, hotels, schools and more.  

Benefits of DCV

Energy-Efficient Ventilation

Energy efficient – As a DCV system optimizes airflow rates based on the indoor air quality, the ventilation rate varies. Therefore, the system only boosts ventilation rates when needed, increasing energy efficiency. 

Cleaner Indoor Air
Improves indoor air quality – Demand Controlled Ventilation supplies fresh, filtered air, and extracts stale moist air, improving indoor air quality.  
Mould & Condensation Control
Eliminates mould and condensation – A DCV system ensures that the right amount of ventilation is provided to control the amount of moisture in the air, helping to eliminate condensation and mould.  
Reduced Thermal Loss
Reduces thermal loss – DCV supplies and extracts air as required. Therefore, rooms are not over ventilated when not in use, preventing cooler outside air replacing the warmer inside air.  
Ventilation Compliance
Complies with building regulations regarding ventilation.
