Healthy Buildings and Air Distribution in Rooms

Healthy buildings are to a great extent a question of indoor air quality. The processes involved in air quality can be looked upon as a number of links in a chain. Typical links will be emission from building materials, convection and diffusion in the room, local airflow around a person, personal exposure and at last the effect of the air quality on the occupant. The best results will obviously be obtained by using building materials with low emission. However, there will always exist some emission and the ventilation will consequently be an important link
