It is known that heat-stressed elements greatly affect the thermal properties of walling and contribute to the heat losses of a building. Heat-stressed elements decrease the temperature on the inner walling surface adjacent to the external corners. In addition to increasing heat losses, heat-stressed elements increase the condensation on the inner walling surface leading to mold appearance. This is one of the reasons that shows that the modeling of heat-stressed elements is a very important design stage. The article discusses the effect from these elements on thermal properties of multilayer walling in the external corner of a building. Using the ANSYS software package, the influence of heat-stressed elements on the heat transfer processes is modeled in the external corner area. A quantitative assessment of the thermal state of typical walling fragments under extreme heat-transfer conditions is given. The obtained research results can be used to increase the temperature in the area of heat-stressed elements and reduce their negative impact.
