policy guidelines

Ventilation impacts the quality of the indoor environment. Indoor air quality (IAQ) contributes to the overall personal exposure of occupants of a building to certain pollutants and is therefore an important environmental determinant of health. Research shows that European citizens spend on average 90% of their time indoors. The Flemish government, and more specifically the Flemish Department of Environment & Spatial Development, has been conducting research on IAQ in homes and schools to inform and develop policy since 2007.
