IEA Annex 14: Condensation and Energy

Abstract

This paper reviews the relations between mould, surface condcnsa tion, chmate, building design and occupancy factors and presents a comprehensive overview of the design guidelines in cool, humid chmates. The analysis showed that the mould condition is more severe than the surface condensation condition, that on an average the standard film coefficient for interior surfaces of 8 W/(m2.K) is too high, that the combined air and humidity transfers in dwellings is convection driven and that the hygroscopic inertia dampens the transient hygric response of an enclo sure.
