An analysis of Ukrainian and foreign literature sources, which highlights the results of analytical and experimental research causation factors that affect the failure-free operation of enclosing structures of the heat insulation shell of buildings. The methods of determination of the probability of thermal defects of fencing constructions with consideration of thermophysical parameters that influence the change of sanitary and hygienic parameters of buildings of the building, designed and built on the basis of different normative base, as from thermally homogeneous and thermally heterogeneous building materials, are considered. It was established that reducing the ability of enclosing structures to provide normative thermal insulation properties under the given operating modes for reasons of the occurrence of thermal failure are determined by a number of factors. On this basis, the thermal failure of the insulation shell of the building according to the thermal regime and the reasons for its occurrence are classified according to the following types: design, construction, installation, operation and conceptual systems at the system level. The results of experimental thermal imaging surveys of existing multistory dwelling houses in Vinnitsa show the presence of deviations of the thermophysical properties of their enclosing structures from the current normative base. Especially essential failure of the insulation shell of the building is inherent in the sites of adjoining fencing structures. The management of energy saving projects for thermodynamics of building envelopes at the stage of developing the investment phase of a project to reduce the thermal failure of the shell to provide comfortable microclimatic conditions in the premises is possible only with a comprehensive assessment of the probability of thermal failure, taking into account possible quantitative and qualitative factors. This task can be solved using the proposed structural and algorithmic model for the implementation of the integrated control project for the probability of thermal failure of the thermal insulation shell of the building, which takes into account the dynamic environment of the project, a variety of design and construction, technological and assembly, operational and conceptual solutions for optimization of the parameters of the heat insulation shell for the creation of normative sanitary and hygienic conditions in the premises.
