Demand Control Ventilation

Demand Control Ventilation Systems gives buildings the the right amount of fresh air, when they need it, and where this is useful. A dcv system uses C02 sensors to measure the quality of the air, and the number of people in a room. It measures temperature and humidity. A dcv system has three main functions.

  • 1: Air Quality. With a dcv system indoor air quality is improved. For example if someone is cooking in the kitchen the dcv will remove the cooking smell. (Know as indoor air pollution) . It does this by increasing the amount of fresh air in the building.
  • 2: Humidity. Humidity levels increase as people breath, wash and cook in the home. If indoor humidity gets a bit high, mould will start to grow. A DCV system can reduce the amount of moist outside air that is brought into a building, and help kept mould growth in check.Humidity affects the comfort factor. Getting the humidity out of the air makes it more comfortable inside, it doesn’t feel so “clammy”. You may have less need to run ceiling fans or other fans to stay comfortable. And if your clothes dryer is inside the house, it will dry your clothes in less time, saving some energy there.
  • 3. Occupancy. It uses the C02 and humidity sensors to see if someone in in the room. If no-one is in the room,the dcv reduces the amount of air required to be heated. This is useful in commercial offices were less than 50% of the rooms have people in them at the same time.

When used correctly a DCV system lowers the amount of air that must be heated, cooled or dehumidified in a building.This saves energy and lowers bills. So this saves money.


How does the system work?

A central extract fan is located somewhere in the home, typically in an attic or storage area. This fan runs quietly 24/7. The fan is ducted to the wet rooms such as Kitchens & bathrooms. Extract grills in the ceiling adjust depending on the humidity level to determine the amount of air extracted from each room.

Fresh air is then drawn into the house though wall/window vents located in the bedrooms & living areas. These vents open & close depending on the ventilation requirement. No electrical connections or ducting is required for the inlets.

The results leave the building with clean air with minimal heat loss. The system is simple and effective and has been installed in more than 3.2 million homes worldwide.
