Ventilation and Indoor Air quality

Ventilation is necessary to provide a healthy and comfortable internal environment for buildings. The main task of ventilation is to remove polluted indoor air from a building and replace it with outside air.

There are different types and sources of pollution within the home, for example:

  • Moisture e.g. from washing, cooking.
  • Carbon monoxide (CO) and oxides of nitrogen e.g. from combustion alliances, smoking.
  • Volatile organic compounds (VOCs), e.g. from aerosols and formaldehyde found in some furniture.
  • Allergens e.g. from house dust mites.
  • CO2 e.g. from humans and also combustion appliances.
  • Environmental tobacco smoke (ETS).
  • Odours e.g. from cooking, bodies and pets.

As insulation and building standards have improved, homes are becoming more airtight and ventilation systems are increasingly necessary in all homes to maintain good indoor air quality. Visible signs such as condensation and mould growth will show clearly the need for ventilation but you may still have poor indoor air quality without any visible signs, and this could be affecting your health.

The BEAMA Ventilation group represents leading UK manufacturers and suppliers of ventilation products and equipment whose products deliver the highest standards of build quality and performance. The group is dedicated to improving the indoor environment of buildings through effective, low energy ventilation systems, and to improving standards of installation and commissioning.
