Abstract

This article presents the simulation methods for hygrothermal whole building simulation and thermal bridge simulation as well as their coupling. After validation of the thermal bridge module, which ensures a standard-conform implementation, an exemplary application case for the new simulation software is shown. Mould growth is sometimes found in the non-insulated and before damage free apartment, in cases where one of two side-by-side apartments is retrofitted with interior insulation. It is shown, how the temperature distribution in the exterior wall is changed due to the partial interior insulation measure. The influence of room temperature, moisture production, room ventilation and insulation thickness on the relative humidity on the coldest spot in the corner is analyzed. The partial retrofit causes higher and sometimes critical moisture conditions on the connection between exterior wall and party wall.
