DCV (Demand Controlled Ventilation)
Save on your energy bill and provide your home with clean, fresh air.
Demand Controlled Ventilation
Save on your energy bill and provide your home with clean, fresh air. Every home needs fresh air to come into the building from outside, for you to breathe. It’s also vital that stale and damp air and pollutants are removed – both for your health, and the integrity of the building.
Opening windows and doors – so-called purge ventilation – teamed with extractor fans in kitchens and bathrooms will do the job, but of course causes heat loss. To ensure that you are saving energy but also creating a healthy home, it’s vital to consider how the house is ventilated. Demand Controlled Ventilation systems are a solution. They exchange stale air for fresh air, and recover heat in the process.
What is a DCV system
Demand control ventilation is a ventilation method that ensures quality indoor and can save energy and reduce costs. A DCV system consist of sensors, controllers and ventilation fans. The sensors continuously measure and monitor indoor air quality and provide information to the controller.
The controller sends this information to the fans and adjusts the rate of ventilation according to the demands of each room.
The extract fans, are placed in attic spaces or utility rooms and are connected via ducts to extract grilles in wet rooms (kitchen, bathroom, utility). Air comes into the house through humidity sensitive wall inlets in the dry rooms (bedrooms, living rooms).
