Improving the energy efficiency of building envelopes can make a huge contribution to the development of industry by reducing the cost of heating and ventilation of buildings. The aim of the work is to identify possible reserves of energy resources savings by detecting defects in structures and the use of building materials that do not meet the climatic conditions of the region and to make proposals for the optimal solution of the problem. Research objectives: conducting an instrumental survey of buildings, analysis of the results of the survey, analysis and calculation of resource savings by insulating the walls of buildings. Modern methods of research of building structures for compliance of their thermal-physical properties with the normative requirements are offered. The estimation of heat protective properties of protecting constructions of buildings on the basis of thermal imaging inspection for revealing the latent defects of constructions and heat isolation is presented. Consumption of energy resources for heating and ventilation of buildings and structures, the existing measures in the field of energy saving and improving the quality of the enclosing structures are considered, and the results of the instrumental inspection of the object are analyzed. The effective way of increasing the energy efficiency of building envelopes - spraying polyurethane foam - is proposed.
