With the intensification of global warming and the frequent occurrence of extreme climate events, how urban buildings can better adapt to climate change has become a crucial aspect of achieving high-quality urban development and a path within sustainable urbanization. Therefore, within the strategic context of adapting to climate change, enhancing the climate adaptability of urban buildings and promoting urban renewal initiatives are identified as vital pathways. This process is not only related to the comfort and safety of the buildings themselves but is also closely connected to the overall ecological environment of the city, the quality of life of its residents, and the future development of the urban landscape. It is necessary to follow the urban development patterns and fully consider the impact of climatic factors on both cities and buildings. Traditional building construction, as a concentrated reflection of the climatic characteristics and experience of climateadapted building design in this region, still plays an important role in the climate adaptability design of modern buildings and has important reference value.Therefore, this paper takes the Hotan region as an example, which is located in the southernmost part of Xinjiang, analyzing the meteorological data CSWD (Chinese Standard Weather Data) of the region using the Climate Consultant software. It explores into the climatic characteristics of Hotan and their impact on architectural climate elements, including solar radiation, air temperature, humidity and precipitation, and wind. On this foundation, the paper extracts targeted architectural climate adaptability features in conjunction with the specific manifestations of climate adaptability in the architectural design of traditional dwellings in the Hotan area. Further, it employs Visual Data Mining (VDM) technology, combined with the suggested measures from the software analysis, to optimize the climate adaptability characteristics of traditional dwellings in Hotan.The study reveals that the Hotan region is characterized by an extreme arid desert climate, the climatic conditions in the Hotan area are quite unique and less comfortable but possess high potential for climate resources. Combining traditional architectural features, the paper examines the climate adaptability characteristics of traditional dwellings from two dimensions: architecture and climate adaptation measures. The traditional dwellings in the Hotan area exhibit climate adaptability features in architectural dimensions such as layout, organizational principles, enclosure structures, and door and window openings. These are summarized as climate adaptation strategies primarily aimed at enhancing the insulation and heat retention performance of enclosure structures, keeping warm and gaining heat in winter, and cooling, heat prevention, and humidity increase in summer. In addition, climate adaptation measures such as shading, passive solar utilization, greening, and night-time ventilation have a positive effect on climate adaptation. However, current practices are insufficiently responsive to these needs, and with the improvement of living standards and changes in residential living demands, further supplementation and optimization of climate adaptability features through passive strategies are required. Assisted by Visual Data Mining technology (VDM) and combined with the suggestions proposed by the software analysis, this paper puts forward further optimization suggestions in three aspects: formal layout, door and window openings, and construction practicesFor instance, in terms of formal layout, the orientation and layout of buildings are reasonably set according to modern living needs while considering climate adaptation; in terms of enclosure structures, the insulation and heat retention performance of the building enclosure is enhanced; in terms of door and window openings, the size of the openings and shading measures are reasonably arranged to utilize passive solar energy; in terms of construction practices, measures that can be adjusted according to climate changes, such as planting green trees, are added. In summary, this study provides a theoretical basis and practical guidance for the renewal and optimization of traditional dwellings in the Hotan area, which is of great significance for enhancing the climate adaptability of urban buildings and promoting sustainable urban development. At the same time, it also offers beneficial references for architectural design and renewal in cities with similar climatic conditions
