Under rural revitalization and low-carbon development, the sustainable transformation of vernacular architecture has become an important research focus. Taking the Linpan as the research object, this study proposes an integrated design methodology that combines typological translation with ecological material logic for contemporary architectural design. The methodology decodes the Linpan spatial prototype—characterized by the “house–forest–field–water” structure—by abstracting key spatial relationships and translating them into contemporary architectural formal strategies, while incorporating locally grounded ecological materials to coordinate environmental performance and cultural continuity. The proposed approach is validated through the Daoming Zhuli project in Chengdu, where typological translation generates courtyard-centered layouts, semi-open transitional spaces, and bamboo-based envelope systems adapted to a humid subtropical climate. A scenario-based material comparison indicates that the use of local materials can significantly reduce embodied carbon emissions while reinforcing regional identity. In addition, comparative analyses of other vernacular settlements, including Huizhou ancient villages, Fujian Tulou, and Ait Benhaddou, are conducted to examine the methodological transferability across different climatic, spatial, and cultural contexts. This study contributes a design-oriented framework linking spatial typology and material selection, providing guidance for the sustainable renewal of Linpan and references for the contemporary adaptation of vernacular architecture in international contexts.

With the evolution of social structure and the intensification of population aging, traditional community service centers struggle to meet residents’ complex needs due to their functional singularity and spatial rigidity. In response to the continuously evolving social structure and functional requirements, this research proposes a strategy based on the “Separation of Support and Infill,” distinguishing between the building’s permanent Support Structure and its replaceable Infill Components. These two parts are combined with modularization to achieve long-term spatial adaptability and sustainability throughout the entire life cycle. In terms of functional space, through the combination of vertical stratification, horizontal staggering and spatial permeability, a three-dimensional composite space system is constructed, which not only enhances the functional flexibility but also improves the environmental performance. Taking a design case in Yicheng District, Zhumadian City as an example, through a comparative analysis with the traditional building model, the comparative analysis demonstrates that this framework increases the Floor Area Ratio (FAR) by approximately 0.15 compared to traditional models. Furthermore, the modular characteristics significantly enhance demountability and reusability, reducing construction and demolition waste while lowering life-cycle costs by an estimated 15% to 25%. These studies show that the support structure and the composite functional space system can not only promote social interaction and community cohesion but also reduce the life-cycle cost and carbon emissions. The framework proposed in this paper constructs a theoretical and practical system for sustainable community buildings from the perspectives of functional compounding and low-carbon community development. Its innovation lies in its flexible spatial organization mode and the enhancement of the sustainability of community buildings.

The optimization of ventilation strategies in high-ceiling theater stage spaces is crucial for improving thermal comfort and energy efficiency. This study addresses the challenge of uneven temperature distribution and airflow stagnation in stage environments by employing computational fluid dynamics (CFD) simulations to evaluate the effectiveness of different ventilation modes, including natural, mechanical, and hybrid systems. Six airflow organization scenarios were designed based on modifications to structural layout, equipment settings, and mechanical disturbances (e.g., fan integration). Key evaluation indicators such as temperature uniformity coefficient, airflow velocity, and exhaust efficiency were used to assess performance. The results show that a multi-dimensional optimization approach combining spatial adjustments and mechanical disturbances significantly reduced the average temperature from 26 °C to 23 °C and the temperature uniformity coefficient from 2.79 to 1.49. This study contributes a comprehensive design strategy for stage ventilation that improves comfort while minimizing energy consumption, offering practical implications for performance space design and HVAC system integration.

Due to massive urbanization and industrialization, modern constructions tend to be designed as technique-dependent, at the cost of high consumption and emissions for indoor environment control such as heating ventilation and air conditioning. Space heating accounts for about 40% of total building energy usage in northern China in winter. This calls for self-reflection and tracing of local traditional architectural wisdom. In this paper, Sibe Traditional Houses were chosen as a typical illustrative example to reveal the building mechanisms behind such local-adaptive traditional constructions. Based on the field investigation in Shifosi Village, a traditional Sibe settlement in Shenyang City, northern China, thermal modeling and indoor heating effects are studied in Sibe Traditional Houses with unique building spatial patterns. The indoor thermal environment is comparatively analyzed for both passive envelope insulation and active heating considerations. Preliminary results indicate that enhancing roof thermal insulation enhancement is the key passive strategy for improving indoor thermal comfort in winter. It also suggests that a space-heating configuration that combines the traditional “kang” with the architectural layout has a more significant effect on the enhancement of indoor thermal comfort in Sibe dwellings. This paper can provide methodological support and an application reference for the improvement of indoor thermal environment of traditional village dwellings.

With the acceleration of urbanization, many traditional buildings have been dismantled and built indiscriminately, resulting in a uniform urban landscape. The problem of urban microclimate has been aggravated, and the renovation of historic districts, especially including the renewal of microclimate, has become an important component of sustainable urban renewal. The old commercial street in Huili Ancient City is used as an example in this paper. Through literature research, we note that previous studies have mainly examined the renewal of historic districts from the perspective of the old city environment, while most of the traditional neighborhood renewal designs have neglected the wind and heat environments. Combining the limitations of previous studies and field research, we summarized the current problems of the neighborhood and developed specific renovation strategies for the identified problems in terms of historical and cultural heritage, the relationship between the old and the new, and the layout of green building technologies. In addition, the green building strategy was used to optimize the microclimate environment of the neighborhood, and the wind and heat environment simulation was conducted to evaluate the modeling of the renovated neighborhood. The results show that the outdoor wind environment is better in winter than in summer, and the natural ventilation environment of the neighborhood could be optimized by optimizing the building layout to form an alleyway wind. The indoor wind–heat environment simulation was carried out with the Green Pottery Experience Hall as an example, and the indoor and outdoor air circulation and ventilation were good, and the comfort of the human thermal environment was high. This paper explores the updating strategy of the historic district in the transition zone between old and new and the wind–heat environment simulation and evaluation of green building renovation, which provides a new perspective for the related renovation research and the optimization strategy of the microclimate environment in the district.
