What is Demand Controlled Ventilation (DCV)?
A DCV system is a controlled method of ventilating your home that links the amount of fresh air supplied to the occupancy of the home. DCV systems continuously monitor indoor air quality measuring parameters such humidity (H2O), carbon dioxide (CO2) and Volatile Organic Compounds (VOCs) which are harmful to our health. As these levels fluctuate daily so too does the DCV system ensuring that the flow rates are sufficient when levels are high. The system runs in trickle mode when air quality is good. This ensures optimum ventilation throughout the home using the minimum energy to do so.
