Technological Solutions for Increasing the Energy Efficiency of Windows in new Construction and Housing Stock Reconstruction

The article considers the problem of increasing the energy efficiency of translucent enclosing structures of residential buildings. Based on computer modeling of temperature fields in the THERM software package, the influence of the geometric parameters of the windows (exterior window trim, the window's position in a wall cross-section) on the thermal performance of the junction is analysed. The effectiveness of using traditional brick exterior casing in new construction is studied and technological solutions are proposed for the reconstruction of existing housing using polystyrene foam exterior casing. The optimal position of a window in a cavity wall is determined to avoid moisture condensation and minimize the possibility of the cold bridges formation.
