Therefore, this study proposed a self-sufficient artificial component air (ACA) ventilation system to overcome this key issue. Through smoke experiments and computational fluid dynamics (CFD) simulation, the effects of factors such as supply air velocity, temperature, oxygen concentration, and the inlet-to-deflector distance on the diffusion of ACA were analyzed, and the semi-theoretical models were established to describe the descent of the airflow trajectory, the decay of axial velocity and oxygen concentration, which provides a quantitative basis for system design. At the same time, the contribution ratio of indoor oxygen concentration indicated that the ventilation system reaches dynamic equilibrium after 2 minutes of operation. Moreover, the orthogonal experiments and range analysis showed that the supply oxygen concentration is the dominant factor in controlling the oxygen supply efficiency, followed by the supply air temperature, inlet-to-deflector distance, and supply air velocity. The results showed that oxygen concentration of 25%, the airflow velocity of 3.5 m/s, and the inlet-to-deflector distance of 0.1 m achieved the optimal state, ensuring efficient oxygen supply and uniform distribution. This study provides a comprehensive theoretical support and parameter design basis for the ACA ventilation system, and offers a reliable solution for creating a safe and self-sufficient living environment in underground refuge chamber.</div></div>","PeriodicalId":9273,"journal":{"name":"Building and Environment","volume":"298 ","pages":"Article 114613"},"PeriodicalIF":7.6,"publicationDate":"2026-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147682302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, existing research on these materials lacks a systematic synthesis regarding the measurement and evaluation of hygrothermal properties, as well as their integration into models that simulate material-environment interactions. This review therefore provides a comprehensive analysis of assessment methods for moisture buffering capacity and elucidates the relationships among hygrothermal properties and between these properties and pore structure characteristics. Furthermore, the review integrates the moisture buffering capacity of hygroscopic materials to examine improvements and simplifications in hygrothermal models for predicting indoor humidity levels in buildings. Finally, this review synthesizes critical challenges related to measurement and assessment methods, mechanisms of moisture buffering capacity, and model improvements, spanning from experimental research to practical applications. The establishment of an “assessment–characterization–mechanism–model” framework is of significant importance in providing the guidance for the measurement and assessment of composite material hygrothermal properties, the development of composite materials, and the model optimization of mass transfer in such materials.</div></div>","PeriodicalId":9273,"journal":{"name":"Building and Environment","volume":"298 ","pages":"Article 114600"},"PeriodicalIF":7.6,"publicationDate":"2026-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147682296","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies have revealed the unequal spatial distribution of UGS using diverse methods. However, existing evaluation approaches often fail to adequately account for sufficient temporal coverage and spatial distribution of Urban High-Temperature Hot Spots (UHS), resulting in less accurate and informative outcomes. This study proposes a novel framework to evaluate UGS distribution across multiple years in Miami-Dade County, Florida, thereby reducing the influence of occasional annual fluctuations while incorporating the spatial distribution of UHS. Applying this framework, we find that communities with high and very high socioeconomic status consistently enjoy high accessibility to UGS and low exposure to UHS. By contrast, although low and very low socioeconomic communities have experienced improvements in UGS accessibility and availability, they have also faced increasing exposure to UHS over time. Furthermore, the highest level of inequity in UGS distribution occurs in high and very high socioeconomic communities, due to some areas holding disproportionately high cooling resources while remaining largely shielded from UHS. Our findings also reveal that communities with higher proportions of white populations, higher incomes, and higher housing prices are associated with lower exposure to UHS and greater access to UGS. The proposed framework advances current research by providing an improved method for evaluating equity in UGS distribution and offers practical insights to guide urban planners in identifying inequitable communities.</div></div>","PeriodicalId":9273,"journal":{"name":"Building and Environment","volume":"292 ","pages":"Article 114274"},"PeriodicalIF":7.6,"publicationDate":"2026-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146076660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, systematically reviewing the status, trends, and challenges of carbon emissions in the building sector holds important significance for achieving carbon neutrality goals. This study analyzed 80 peer‑reviewed papers using quantitative and qualitative methods to compare China’s research progress with that of other countries from the perspectives of research focus, methodological approach, and software tools. The results indicate that life‑cycle assessment (LCA) has become the mainstream analytical method worldwide; however, methodological subjectivity in defining system boundaries continues to limit result comparability. Chinese studies tend to emphasize emissions in the construction phase, while international research concentrates on operational and maintenance stages, revealing different developmental priorities between emerging and mature construction markets. In terms of technical tools, China still relies heavily on domestic platforms such as Glodon and less on advanced simulation tools like SimaPro or EnergyPlus, suggesting opportunities for deeper integration with international standards and digital technologies. Overall, these patterns highlight a global convergence toward comprehensive, tool‑assisted life‑cycle carbon assessment, yet also expose the uneven pace of methodological and technological advancements across regions.

Understanding the impact mechanisms and thresholds of urban land use patterns on the surface thermal environment is crucial for cities to formulate climate response planning and design strategies. Multi-source remote sensing data of Shanghai, China were used to retrieve the land surface temperature (LST) and the 2D/3D morphological indicators. The Random Forest-SHAP method was applied to explore the multi-scale and multi-seasonal impacts and threshold effects of urban morphology on surface thermal effect intensity (STEI). The results showed that: (1) Construction land was the major contributor to urban warming in Shanghai, whereas water bodies were the main cooling factor; vegetation contributed relatively little to STEI and exhibited seasonal variations. (2) The impacts of 2D and 3D morphological indicators on STEI exhibited significant scale effects. At a small scale (300 m), 3D morphological indicators were the most influential in summer (52.57%), whereas at a large scale (2400 m), 2D morphological indicators played the most important role in spring (90.64%). The average importance of 2D morphological indicators (73.01%) was greater than that of 3D morphological indicators (26.99%). (3) The leading morphological indicators influencing STEI varied across seasons. STEI was primarily influenced by the 2D composition index of water bodies in spring, by the 3D building index in summer, and by both the 2D and 3D building indices in autumn and winter. (4) Threshold effects were identified in the influences of 2D and 3D morphological indicators on STEI, with thresholds varying across scales and seasons. These findings reveal the nonlinear impact mechanisms of urban land morphology on STEI, which can provide a reference for urban planning theory and practice aimed at heat mitigation.</div></div>","PeriodicalId":9273,"journal":{"name":"Building and Environment","volume":"292 ","pages":"Article 114287"},"PeriodicalIF":7.6,"publicationDate":"2026-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146076657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
