Measurement of air leakage characteristics of house enclosures

The heat loss associated with air leakage through the enclosure of a typical detached house may be as much as 40 percent of the total heat loss. It is essential, therefore, to be able to estimate this component of the heating load with reasonable precision. This paper describes a series of tests conducted on six wood-frame houses which established rates of overall air leakage and leakage through windows, doors, walls and ceilings, separately.L'auteur pr\ue9sente les r\ue9sultats d'une s\ue9rie d'essais men\ue9s sur six maisons unifamiliales en vue de d\ue9terminer les fuites dans leur ensemble ainsi que les fuites \ue0 travers les fen\ueatres, les portes, les murs et les plafonds. Un ventilateur axial \ue0 h\ue9lice sert \ue0 r\ue9duire les pressions \ue0 l'int\ue9rieur de la maison et \ue0 mesurer la vitesse d'\ue9coulement et les diff\ue9rences de pression qui en r\ue9sultent dans l'enceinte de la maison. Ces essais cherchent \ue0 \ue9valuer la vitesse de p\ue9n\ue9tration de l'air dans les maisons.Presented at the 1975 ASHRAE Semiannual Meeting, Atlantic City, NJ, USA, Jan 26-30, 1975Peer reviewed: YesNRC publication: Ye
