Determining the optimal insulation thickness for external walls and assessing its cost-effectiveness
Аннотация
Improving building energy efficiency increases global energy efficiency, which is the policy's main priority. Improving thermal efficiency in buildings is a top priority of global energy policy. The fact that the building sector accounts for 36% of total energy consumption and 40% of CO₂ emissions worldwide underscores the urgency of this issue. In Uzbekistan, the residential sector is one of the largest energy consumers, accounting for 34.8% of the country's total energy consumption. Therefore, insulating external walls is crucial for improving energy efficiency and reducing environmental emissions. In this study, an algorithm for calculating insulation thickness was developed in Python, and optimal thickness values were determined for the climatic conditions of the Khorezm and Jizzakh regions using expanded polystyrene foam and basalt wool. The results showed that the optimal thickness is determined not only by climatic indicators but also by the materials' thermal properties and economic parameters. The proposed approach provides an important scientific and practical basis for ensuring energy efficiency, minimizing economic costs, and making informed decisions tailored to regional conditions.
