Indoor climate and health
Research reveals a clear link between indoor climate quality and human health. A large number of homes are failing to meet national air change requirements. In eight out of ten apartments in tower blocks, the air change rate is too low, and 40 per cent of all children are affected by asthma or allergies. Good ventilation halves this risk to child health.
Poor indoor climate is typically caused by hazardous substances emitted by construction materials (e.g. radon), and by moulds and air pollutants. High humidity in buildings and in indoor air can also be a factor. This means that the air in residential properties needs to be replaced continually.

Energy consumption and the environment
Assessing residential ventilation systems and their control is the first step towards reducing energy bills and running costs. A reduction in the energy requirement for achieving the desired indoor climate also means that your carbon footprint will be reduced. A great place to start is by recovering the heat from the spent ventilation air.
One way of achieving this without compromising on either indoor climate or air quality, is to demand-control the climate in each apartment. The result is a comfortable indoor climate with minimum energy consumption and maximum energy recovery, which also meets all the requirements for supply and extract air flows.
