The effect of wind on the heat demand of dwellings. Der Windeinfluss auf den Warmebedarf von Wohnbauten.

Discusses standards and guidelines used for calculating the heat demand over a heating season. Notes inadequacy of current methods, in particular the inadequate account taken of certain environmental conditions and of particular window constructions. Proposes improved sizing procedure to take into account heat loss due to infiltrating air. Discusses simplifying assumptions. Gives expressions for critical heat output and for the quantity of air infiltrating a room. Derives overall energy demand showing critical combination of theoutdoor air temperature and wind speed for the dimensioning of heating installations.
