ABSTRACT

The optimization of the thermal performance of building envelope systems is a critical approach to achieving building energy efficiency and sustainable development, playing a significant role in addressing global climate change and energy crises. This study aims to propose an optimization method based on multi-factor coupled analysis by systematically investigating the heat transfer characteristics of building envelopes, thereby enhancing their thermal insulation properties and reducing energy consumption. A combination of numerical simulation and experimental validation was employed, utilizing a dynamic thermal performance evaluation model to quantitatively analyze the performance of envelope systems under various material combinations, construction configurations, and climatic conditions. The results indicate that optimizing material selection and construction design can substantially decrease heating and cooling loads of buildings, with specific composite material systems demonstrating superior thermal stability under extreme climatic conditions. Furthermore, this research innovatively incorporates an environmentally adaptive design concept, proposing a dynamic regulation strategy that varies with seasonal changes, which further improves the overall performance of building envelopes. The findings suggest that this optimization method not only effectively reduces operational energy consumption but also provides theoretical support and technical guidance for green building design, holding significant value for promoting low-carbon transformation in the construction industry.
