The analysis of structural solutions of external bearing three-layer walls of multistory buildings designed in the Republic of Bashkortostan according to SNiP 23-02-2003 “Thermal Protection of Buildings” before updating from the point of view of their influence on the specific heat protection characteristic of the building as a whole is made. Some discrepancy of buildings considered to current norms in terms of specific heat-protecting characteristic due to the low coefficient of thermal uniformity of multilayered external walls are revealed and the fragments of facades with maximal heat losses are selected. The required level of external walls resistance to heat transfer along “the surface” at existing structural decisions of the façade parts with thermal non-uniformities is shown; ways of improving the design solutions from the position of requirements of SP 50.13330.2012 “Thermal Protection of Buildings” are proposed.
