Mechanical Ventilation

Why Ventilate?

Buildings need a constant supply of fresh air to assure the on-going health of occupants. It prevents condensation, removes pollutants and odours and ensures the safe and sustained performance of some combustion appliances.

Effective ventilation should be achieved by design rather than accident or reliance on natural means. This is why TEHVA promotes the use of properly specified, continuous or well controlled background mechanical ventilation products that offer high efficiency in tandem with effective ventilation rates.

Ultimately, a building’s ventilation strategy should be based on the principle of Build Tight Ventilate Right i.e. ensure a balance between energy efficiency (reduced heat loss) and indoor air quality (a sustained level of healthy air).
 

Why Choose Mechanical Ventilation?

Mechanical ventilation, whether continuous, supply or intermittent in operation, ensures that moisture is controlled and a reduction of air pollutants providing the following benefits:

• Reduced risk of condensation
• Reduced cold air draughts
• Control of dust mite populations and allergenic materials
• Supplementary heating (where heat recovery is offered)
• Boosted extract for high moisture areas
• Reduced external noise ingress

Some mechanical ventilation products provide a heat recovery benefit as they use extracted air to pre-heat the supply air.

TEHVA members offer a range of these product types with low energy fans and high performance heat exchangers that give a major energy efficiency benefit as they are energy positive in operation. They also provide a range of sensors and controllers that ensure the fan is only operating when required, thus contributing to the need to conserve energy.
