Thermohygrometrical Behaviour of Residential Buildings in Unsteady State Conditions: Influence of Orientation

Abstract

A theoretical method is descnbed to evaluate the rate of vapour generation inside a residential building in which surface condensation may occur on the interior sur face of external walls.

The analytical model refers to an ambient surrounded by multilayered internal and external walls; the latter subjected to variable outside boundary conditions.

Results show that the amount of vapour generation permissible inside without condensation depends on the orientation of the ambient and on the thermal storage capacity of its external and internal walls.
