Climate Adaptation Analysis and Comfort Optimization Strategies for Traditional Residential Buildings in Hot-Summer, Cold-Winter Regions: A Case Study in Xuzhou, China

Climate change and the energy crisis have catalyzed the architectural industry’s consideration of green and energy-efficient buildings. With the continuous deepening and expansion of research, people have gradually realized the reference value of the passive design strategies embedded in traditional residential buildings for contemporary architectural design and renovation. This paper takes the traditional residential buildings on Hubu Mountain, Xuzhou, as its research object, and explores their thermal and wind environment characteristics through field investigations and software simulation analysis. It is found that Xuzhou’s traditional houses have good temperature regulation, with fluctuations of about 5 °C indoors and 10 °C outdoors in summer and about 7 °C indoors and 12 °C outdoors in winter. Their form, material and structure are well adapted to the local climate. There is also a need to optimize the buildings’ moisture resistance and ventilation for better comfort. Subsequently, this study analyzes the climate adaptability features in traditional building construction techniques and then extracts climate adaptability methods, proposing targeted optimization and renovation suggestions, aiming to contribute to the sustainable development of architecture and ecology.
