Fresh air for healthy living: Ventilation is not a luxury

SolarLueften GeldPoor air is unpleasant and unhealthy. If there is insufficient ventilation, the air does not contain enough oxygen; unhealthy outgases accumulate from furniture and textiles. Problems with dampness and mould develop.

Energy saving and quality of living

In general, not only the consumed air  escapes from the building but also valuable heat. Therefore, energy-saving buildings have to be build as insulated as possible. Nowadays, windows in new buildings are very good insulated so that no air can escape from indoors. This can cause dampness and mould inside the room if the windows aren‘t constantly opend for ventilation. Alternatively, a ventilation system can be installed - a solar energy integrated ventilation system would be ideal.

Legal provision

In most of the European countries a minimum exchange of air in new buildings and during renovation projects must be guaranteed.
