LoginDescribes three research programmes measuring tightness of components, of specific areas of a building and of complete buildings. Defines the Belgian standards currently applicable. For air tightness, the area or building is depressurized by 5 to 100 Pa and the flow of air that enters is measured. Thenthe components are made air tight one by one, and each time the new flow rate is measured to give values for the different components. The specific area alone can be depressurized, the specific area plus the whole building or just the whole building. For water tightness, the building is maintained at various pressures and sprayed with water for 5-10 minutes. Tracer gas methods were also used on two houses, and on external woodwork.
