THEORETICAL APPROACHES TO CHOOSING THE SEQUENCE OF IMPLEMENTATION OF ENERGY-EFFICIENT MEASURES IN BUILDINGS

Abstract

The article systematizes theoretical approaches to determining the optimal sequence for implementing energy efficiency measures in buildings of various functional types. It examines economic and mathematical models used to optimize the order of implementation, including methods of multi-criteria optimization, linear programming, and dynamic programming. Technical interdependencies between individual measures and their impact on the overall effectiveness of thermal modernization are analyzed. Ukrainian experience is summarized with consideration of the country’s division into two climatic zones and compared with European practices. The study substantiates the rationale for prioritizing measures aimed at reducing energy loads before modernizing engineering systems, which ensures appropriate equipment sizing and reduces capital expenditures.
