Abstract
Analysis and calculation of thermal bridges for improvement of residential buildings’ energy efficiency
In the scope of the article the problem of heat and humidity structural damage’s adverse effect on energy efficient building maintenance is considered. The main object of the research is the calculation and analysis of thermal bridges as a considerable factor, making worse the energy efficient building qualities. First the analysis of the most widely-spread structural damages were examined, then the thermal bridges estimation on the basis of Austrian software „AnTherm“ was carried out which represents an universal software package of thermal bridges damaged structural thermodynamic behaviour’s analysis. The calculation of a 60th year building house’s structural junction of foundation plate and wall was carried out. The results enable us to draw a conclusion that the researched structural junction doesn’t create any conditions for the thermal bridges formation.
