According to results of the carried out research, the most significant heat engineering heterogeneous sections of wall enclosing structures of three-dimension block buildings were identified. The use of option with attaching a hinged panel to a threedimensional block with the help of edges along the contour of panel worsens thermal technical mode of the structure. Horizontal junction of wall panels carries the greatest thermal risks and is most responsible when designing a building. Structures of outer wall panels with ribs have practically no potential for energy saving. Fastening a hinged panel to a three-dimension block with the help of dowels equally spaced in the panel plane improves its thermal performance. Compared to the design solution in the proposed option the reduced resistance to heat transfer of outer walls is increased by 31%. High heat insulating effect in this case is achieved by improving design solution of the wall, rather than increasing thickness of insulation layer, which is an economically feasible measure. Designs of outer wall panels with dowel connections are promising from the point of view of thermal protection and can be used for thermal renovation of facade systems in three-dimension block buildings.
