Special Issue Information

Dear Colleagues,

The increasing urgency of climate change and the need for sustainable development have prompted significant interest in improving the thermal performance and energy efficiency of buildings. This special issue aims to gather innovative research that explores the latest advancements in building materials, design strategies, and technologies that enhance thermal performance while reducing energy consumption. We invite contributions that address the integration of passive and active design approaches, the role of renewable energy sources, and the application of smart technologies in achieving energy efficiency. Additionally, studies that investigate the life cycle impacts of buildings, including energy use, carbon emissions, and thermal comfort, are encouraged. By showcasing interdisciplinary research and case studies, this issue will provide valuable insights for architects, engineers, policymakers, and researchers, fostering a collaborative approach toward sustainable construction practices. Together, we can contribute to a future where buildings are not only energy-efficient but also resilient and conducive to the well-being of their occupants.

The strategic coordinated development of land urbanization and carbon emission systems in urban agglomerations is crucial for achieving dual carbon goals and sustainable development. While existing studies emphasize population and economic urbanization, the spatiotemporal coupling mechanisms between land urbanization (encompassing size, input, and output dimensions) and carbon emissions remain underexplored. This study collects data on land urbanization and carbon emissions from 27 cities in China’s Yangtze River Delta urban agglomeration between 2010 and 2019. By establishing evaluation systems for land urbanization and energy consumption carbon emission subsystems, by and employing coupling coordination degree models with spatial autocorrelation analysis methods, this paper analyzes the spatiotemporal dynamic evolution characteristics of the coupled coordination relationship between land urbanization and energy consumption carbon emissions in the Yangtze River Delta urban agglomeration. The results indicate the following: (1) From 2010 to 2019, the comprehensive level of the land urbanization subsystem in the Yangtze River Delta urban agglomeration continued to rise, with higher comprehensive indices in the southern and northern peripheral regions and lower values in central urban areas. The carbon emission subsystem showed sustained stable decline, with a gradual reduction in the number of cities maintaining low carbon emission levels. (2) Temporally, the overall coupling coordination degree of the urban agglomeration system demonstrated an upward trend, progressing from severe imbalance to the primary coordination stage. (3) Spatially, significant regional differences in coupling coordination degree were observed, showing higher values in the southeastern areas compared to the northwestern regions. (4) Most areas exhibited no significant clustering characteristics in the coupling coordination degree between land urbanization and energy consumption carbon emissions, while the local spatial clustering patterns demonstrated temporal variations. These findings systematically reveal the transition mechanisms of land–carbon coordination in urban agglomerations, providing empirical evidence to resolve the theoretical debate on urbanization’s dual role in emission promotion and reduction.

Optimizing the wind environment within university dormitory areas is essential for ensuring student safety, enhancing living comfort, and improving building energy efficiency. In this study, the wind environment of multi-story university dormitories in cold regions is comprehensively investigated through computational fluid dynamics (CFD) simulations conducted with the PHONECIS software (version 2019), combined with orthogonal experimental design methods for systematic analysis and optimization. Through orthogonal experimental design, the effects of key morphological parameters—including building layout, length, width, and height—on the near-ground wind environment were evaluated. Among these, building width exerted the greatest influence, followed by building length, layout form, and finally building height. Based on the analysis, the optimal design scheme features a staggered building layout, with individual dormitory buildings measuring 60 m in length, 16 m in width, and 11.4 m in height. This optimized design was implemented in the multi-story dormitory area of the eastern section of Chang’an University’s New Campus. A comparative analysis of wind speed distribution before and after optimization, conducted specifically for the outdoor spaces during the winter season, revealed that the average near-ground wind speed was reduced from 3.3 m/s to 2.7 m/s, achieving an 18% reduction. The staggered arrangement and adjusted building proportions effectively dispersed airflow, mitigated high-velocity zones, and significantly enhanced outdoor wind comfort and pedestrian safety. This study introduces a morphology–wind environment coupling strategy from an architectural perspective to guide the design of dormitory buildings in cold regions. Rather than focusing on mathematical modeling, the research emphasizes design-oriented outcomes aimed at informing and optimizing practical architectural solutions for safer, more comfortable, and energy-efficient campus living environments.
