Demand Controlled Ventilation 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.
A demand controlled fan unit is installed in the attic/ utility or plant room. A separate duct is installed from the fan unit to the wet rooms such as the kitchen, utility, bathrooms & WCs. Sensors, fitted inline in the duct, or in the room, depending on the brand used, measure air quality in each area. Based on these readings, humid or stale air is extracted from the wet areas and fresh air is drawn into to the house through wall or window vents strategically positioned in each habitable area such as bedrooms, living rooms etc.
