Demand Controlled Ventilation – A Simple Guide
Demand control ventilation sounds like a complicated process, but really it’s not, so we have compiled a simple guide to demand controlled ventilation, to help clarify what exactly it is.
It is commonly accepted that most water distribution facilities work on demand, so why should it be different for air distribution, with each cubic metre of fresh air to warm during the heating season having a significant economic and environmental cost?
The concept of demand controlled ventilation rests on the principle of providing occupants with the right amount of fresh air, when they need it, and where this is useful. With intelligent airflow management, energy savings are made on every occasion that the need for ventilation is low or null, which can represent more than half the time. Conversely, an activity which emits indoor air pollution such as food preparation in a kitchen, a shower, or even the release of odorous metabolic compounds, generates a need for a greater airflow to remove the pollution quickly.
So what are the benefits of demand controlled ventilation? In addition to combining indoor air quality and energy saving optimisation, demand controlled ventilation demonstrates many indirect benefits resulting from the reduction of average airflow including:
- Reduced average power consumption of the fan
- Less clogging of filters, ducts and terminals
- Increased life of fans
- Greater availability of pressure and airflow for terminals
- Reduced size of ductwork to gain valuable floor space
