Detaillierte Berechnung der thermischen Parameter einer Baukonstruktion

Wojciech Kozak, Wolfgang Richter

Abstract: The thermal bridges are the weakest points of the building. The most extreme values of the temperature and humidity content occur on them. In spite of that, they are almost never accounted for in the thermal building simulation. This paper presents an extension of the thermal building simulation program that allows for detailed simulation of the thermal bridges coupled with a CFD-calculation of the indoor air movement. Such a combination provides a three dimensional simulation of building envelope together with prevailing thermal conditions and indoor air flow. Therefore, the presented tool allows for a detailed simulation of the critical areas of the building envelope.
