As climate challenges intensify, architectural design must reconcile energy efficiency with environmental adaptation. This study investigates how two skywell geometries in Kunming’s traditional One-Seal dwellings (Yikeyin) optimize seasonal thermal and ventilation performance. Combining field analysis and simulations, a comparative analysis of skywell depth-to-width ratios reveals that larger proportions enhance summer airflow but exacerbate winter heat loss, while smaller ratios stabilize winter conditions. Vertical thermal stratification highlights distinct microclimates across floors, with skywells exhibiting pronounced seasonal fluctuations. The findings affirm the climate-responsive intelligence embedded in vernacular architecture, demonstrating its relevance for contemporary sustainable design. By bridging traditional wisdom and modern green building practices, this work advances strategies for climate-resilient architecture and rural habitat enhancement, prioritizing both ecological balance and human comfort.
