Abstract

In 1997, in accordance with the UN framework Convention on climate change (UNFCCC) the Kyoto Protocol was adopted. In the Committee on adaptation (2012) States the need for all countries participating in the UNFCCC to develop national plans and programs for adaptation to conduct a technical study of the process of adaptation in different spheres and primarily in energy-intensive industries such as construction and operation of residential and administrative buildings. Based on the numerical solution of the differential equation that determining one-dimensional heat transfer under nonsteady conditions with constant coefficients, the method of calculation of the temperature distribution over the cross section of the enclosing structure was developed. On the basis of the developed method of determining the number of cycles of freezing and thawing of moisture in the cross sections of the outer wall of the building are calculated. The developed method was tested in the experiment on the exterior walls of operated buildings. The results showed good convergence of the real and calculated temperature values. The calculation of the number of cycles of freezing and thawing on the cross section of the outer wall of the building according to the developed methodology and the experiment showed the same results. The method of numerical assessment of the impact of global climate change on the enclosing structures was developed. The concept of temperature intensity of the year was introduce. The method uses meteorological data of outdoor air temperature for the previous period and the results of calculation of temperature regime of the enclosing structures. The use of this method allowed to calculate the number of cycles of freezing and thawing in cross sections of the outer wall at any time interval, and, therefore, more accurately predict the durability of the enclosing structures.
