Expediency of application of approximate methods to problems of building thermal physics

Abstract

This paper shows the advantage and possibilities of application of approximate solution methods to typical and actual problems of building thermal physics. Specific examples of successful solution of rather complicated problems are given and the accuracy of the obtained solutions is evaluated. Without detracting from the advantages of numerical solutions, the possibility of assessing their reliability in comparison with approximate solutions is shown. It is noted that approximate solutions of a large number of problems can be successfully used in engineering practice.
