Influence of a Refurbishing on an Old Residential Building’s Wall in Paris in Summer: Mass and Heat Transfer Approach
The implementation of thermal insulation in old residential building walls could compromise the hygrothermal behavior of the construction, especially in summer time when it is placed inside. A bad installation of insulation could have consequences on the quality of indoor air conditions and on the health of the wall mostly during hot periods. Thus, the evaluation of heat and mass transfer through the wall is an important task. The aim of this study is to evaluate through a hygrothermal 2D-model, the behavior of two multilayered renovated walls. Modelings are made under real external conditions (for a building located in Paris). COMSOL Multiphysics® software is the modeling tool adopted, with the PDE interface which allows the coupling of mass and heat equations
