Buildings for the Canadian climate

Climatic conditions in Canada vary widely, as may be seen from the extensive information available, and for building purposes may be classed roughly as to winter conditions as wet-temperate, dry-cold, moderately wet-cold and very wet- moderately cold. Summer conditions are generally warm. The development of a building science has aided understanding of the climatic effects upon buildings. Water is seen to be the great promoter of building fabric difficulties, arising primarily from rainfall. Cold climates can also produce severe wetting difficulties, leading to destructive effects, arising from condensation in winter, especially in humidified buildings.Les conditions climatologiques au Canada varient largement, comme on peut s'en apercevoir par les renseignements disponibles et qui pour fins de construction, peuvent \ueatre classifi\ue9es sous des conditions d'hiver comme \ue9tant de humide-temp\ue9r\ue9e, froide-s\ue8che, mod\ue9r\ue9ment froide-humide et tr\ue8s humide-mod\ue9r\ue9ment froide. Les conditions estivales sont g\ue9n\ue9ralement temp\ue9r\ue9es. Le d\ue9veloppement de la science du b\ue2timent a aid\ue9 \ue0 comprendre les effets climatologiques sur les b\ue2timents. L'eau semble \ueatre la grande artisane des difficult\ue9s de fabrication dans la construction, d\ue9rivant principalement de la pr\ue9cipitation. Les climats froids peuvent \ue9galement produire des difficult\ue9s humides assez importantes qui proviennent de la condensation et de l' humidification des b\ue2timents en hiver et conduisent \ue0 des effets destructifs quand ces conditions sont suivies de gel \ue0 l'\ue9tat humide.Peer reviewed: NoNRC publication: Ye
