FORMALIZATION AND HIERARCHICAL CLASSIFICATION OF THE PARAMETERS OF INFLUENCE ON THE ENERGY EFFICIENCY OF ENCLOSURE STRUCTURES OF BUILDINGS

Based on the results of the analysis of research on the development of scientific and methodological foundations and practical experience of organizing and managing the technological process to increase the energy efficiency of buildings, the main factors influencing the amount of energy costs during the life cycle to ensure the standard sanitary and hygienic parameters of the premises were identified. The necessity of identifying the regularities of the methodological foundations of optimization of factors influencing the energy efficiency of the enclosing structures of buildings is emphasized. It is pointed out the expediency of taking into account the total energy consumption during all stages of the life cycle of buildings when determining the energy efficiency of the enclosing structures of buildings. Mathematical modeling of multi-parameter assessment of energy efficiency of building enclosing structures is expedient to be performed using the method of fuzzy logic and linguistic variables. The proposed hierarchical classification and formalization of the parameters influencing the energy efficiency of the enclosing structures of buildings, which are a fuzzy knowledge base combining linguistic assessments of input and output factors that affect the target function, are given. The total energy expenditure for the entire life cycle to ensure the energy efficiency of the enclosing structures of buildings at the system level as a linguistic variable is characterized by functional dependence on the linguistic variables that characterize the energy expenditure for capital construction, operation and recycling of materials. The generalized model of the relationship between the parameters of influence at the system level on ensuring the energy efficiency of the enclosing structures of buildings as their hierarchical classification is presented in the form of a logical conclusion tree. The root of the logical conclusion tree determines the total energy consumption to ensure the energy efficiency of the enclosing structures of buildings, and the hanging vertices are the determining parameters of influence, the variation of which allows finding the optimal value of the objective function according to the specified criteria.
