So why do we need ventilation?
Building regulations require a minimum rate of ventilation approximately equivalent to half an air change per hour for the whole building. Even if building regulations did not require this, a minimum level of ventilation is such a good idea as it helps prevent condensation and the respiratory problems associated with stale air.
General improvements in house construction, building regulations and much higher levels of insulation in modern dwellings mean that houses are becoming almost airtight. Consequently, the air inside becomes stale with a build up of moisture and smells. The moisture can result in condensation and mould, and a generally ‘stuffy’ atmosphere.
