Calculation of additional heat loss through heat-conducting inclusions (on the example of window reveal)
To solve the problem of improving the energy efficiency in buildings the materials with low thermal conductivity are used. The constructive difficulty of the modern walling and the heterogeneity of materials must be carefully calculated in designing, constructing and operating of buildings.The metho...

To solve the problem of improving the energy efficiency in buildings the materials with low thermal conductivity are used.

The determination of the value of additional heat flows is carried out by calculating the temperature fields.The results show that the value of the additional heat flows depends not only on the constructive solution of nodes, but also on the architectural design of buildings. That’s why it is necessary to define a reduced thermal resistance for each building’s facade.
