The Calculation of house infiltration rates

During 1960-62, DBR/NRC conducted air leakage measurements on two single-story houses built during the nineteen fifties using the tracer gas technique. It was followed several years later in 1967-68 by the measurement of the air leakage characteristics of their enclosures using the house pressurization technique. The results of these tests on the two houses were used to develop a procedure for calculating infiltration rates similar to the one recently developed for high-rise buildings. Also, research needs were identified so that the calculation procedure can be applied to houses of different design, construction and wind exposure.Entre 1960 et 1962, la DRB du CNRC a mesur\ue9 les fuites d'air au moyen de la technique des traces de gaz, de deux maisons \ue0 un \ue9tage construites dans les ann\ue9es 50. Quelques ann\ue9es plus tard, en 1967-1968, les caract\ue9ristiques de fuite d'air des enceintes ont \ue9t\ue9 mesur\ue9es au moyen de la technique de pressurisation. Les r\ue9sultats de ces essais sur les deux habitations ont servi \ue0 mettre au point un proc\ue9d\ue9 de calcul des taux d'infiltration de l'air similaire \ue0 celui r\ue9cemment mis au point pour les \ue9difices en hauteur. L'auteur a aussi identifi\ue9 les besoins de recherche afin que la m\ue9thode de calucl puisse \ueatre appliqu\ue9e \ue0 des habitations de conception, de construction et d'exposition au vent diff\ue9rentes.Presented at the 1979 ASHRAE Semiannual Meeting, Philadelphia, PA, USA, Jan 28-Feb 1, 1979Peer reviewed: YesNRC publication: Ye
