Ventilation in single family dwellings - a system analysis. Ventilation i smahus - ett systemanalys.

Describes sealing houses against air infiltration to allow controlled ventilation. Notes inherent risks in poor ventilation such as high radon content and its associated decay products, poor air quality, moisture, condensation, mould and allergy-producing dust particles. Treats requirements in swedish building code and stipulated minimum air change rate. Comprehensive series of graphs illustrates air change rate as function of wind speed and different grades of building air tightness. Gives example for calculating energy required to heat ventilation air on basis of air change rate, volume and degree days.
