The influence of air change and ageing on emissions from 5 different building materials were studied. It was concluded that increasing the air change rate in a rather leaky house was of practically no importance in preventing problems caused by emissions. It was also assumed that a reduction of the air change rate in a tight house may result in a considerable increase in the concentration of substances in the room air. For all 5 materials, the emission rate decreases with time. The experiments indicate that, especially during the first 3 months after the building is finished, very large concentration of emission products from the newly manufactured builidng materials will be present in the room air.
