Abstract
Thermal and hygric properties of porous materials depend on the content of
moisture present in their pore system. As they appear as input parameters of
computational models of heat and moisture transport, neglecting this dependence
can affect the results of computational simulation of both hygrothermal
performance and energy balance. In this paper, several multi-layered systems of
building materials are analyzed. The hygric and thermal properties of materials
forming the particular systems are determined at first. Then, the effect of their
dependence on moisture content on the moisture and temperature fields is
analyzed using a computational model. The consequences of neglecting the
dependence of the particular parameters on moisture content are discussed and
recommendations for the energy-related assessments of the studied multi-layered
systems are formulated.
Keywords: computational modelling, thermal parameters, hygric parameters,
moisture.
