Today the tendency of building renovation is one-sided, ie thermal resistivity of enclosure constructions is being increased ignoring the temperature control possibilities in flats. Appreciable heat savings may be achieved solely through a duly coordination of the constructive building solutions with the type and power of heating systems and by the evaluation of an unfixed character of heat exchange.In the proposed method a building is treated as a heterogeneous body (∞>Bi>0). The conditions of the 3rd rate are accepted for the heat exchange between the elements of this body and the surroundings (1). The result of the equation solution is the determination of temperature alteration law in each element of a heterogeneous body (2). The non-monolithic enclosure constructions having a final number of elements may be changed by an equivalent monolithic body with equivalent thermal properties (3; 4).
