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.

HVAC systems account for a significant portion of building energy consumption, making them a critical factor in achieving energy efficiency and sustainable development in buildings. The thermal comfort environment within kindergarten buildings has a direct impact on children’s health and learning performance while also being closely linked to building energy consumption. Natural ventilation serves as a fundamental passive technology for ensuring indoor air quality. It offers advantages such as energy savings and emissions reduction while improving thermal comfort, making it a key advancement in promoting sustainable building practices. Air change rate serves as a key indicator for measuring indoor air renewal. This study, based on the characteristics of young children being more sensitive to environmental changes and having weaker resistance, investigated the impact of different air change rates on indoor thermal comfort in kindergartens across three distinct climatic zones in China: hot summer and warm winter, hot summer and cold winter, and temperate areas. Thermal comfort was evaluated using the Temperature Humidity Index (THI) and temperature fluctuation rate. And the effects of air change rates on building energy consumption were further examined. Simulation results show that the influence of air change rates on indoor thermal comfort, temperature fluctuations, and energy consumption varies significantly across climate zones. Guided by the sustainable principles of prioritizing children’s health and low-energy operation, the findings indicate that an air change rate of 1.5 is optimal in hot summer and warm winter areas, a rate of 0.5 is most suitable in hot summer and cold winter areas, and a rate of 0.5 is most suitable in temperate areas. This study aims to provide scientific evidence for achieving energy conservation and sustainable ventilation design through natural ventilation in kindergarten buildings across different climate zones, while ensuring children’s health.

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.
