Airtightness of buildings: Results from airtightness measurements in new Norwegian houses. Boligers lufttethet: Resultater fra lufttethetsmalinger av nyere norske boliger.

Presents the results from a major airtightness survey carried out in Norwegian dwellings. 61 detached houses and 34 flats were pressure tested. In 14 of the detached houses and 6 of the flats, leakage paths were traced using thermography. Gives tables of results. Lists most common leakage paths located by thermography. Occupants of the dwellings were interviewed about draught problems, but there was no clear correlation between occupant dissatisfaction and leakage rate. Notes a considerable variation in leakage between the houses.
