New Method for Assessing the Degree of Deterioration of a Building Into Account a Decrease in the Heat-Shielding Properties of Its Enclosing Structures

Today, it is relevant to develop a methodology for assessing the degree of deterioration of a building based on the loss of heat-shielding properties of its external enclosing structures, and hence the establishment of the physical parameters of the fences responsible for the formation of comfortable conditions in the internal environment of the premises. Based on the research carried out, the dependence of the air flow through the cell of free volume per unit time was obtained as a function of the cell diameter and the modulus of the pressure gradient. This article presents the results of the obtained mathematical model of the interaction of the building envelope with external climatic factors, taking into account the regularities of changes in the characteristics of the outdoor climate
