Glazed sections are typically the weakest in terms of heat transfer, requiring targeted enhancement. This study examines the thermal performance of Energy-Active Window (EAW) systems equipped with internal airflow-modifying elements to enhance convective heat transfer and mitigate heat accumulation within the window cavity. Computational Fluid Dynamics (CFD) simulations were performed under steady-state conditions to analyze temperature distribution and convective behavior. Lower airflow velocities (0.24 m/s) improved thermal uptake, resulting in an outflow temperature of 38.8 °C and an average pane temperature difference (ΔT) of 15.9 °C. In contrast, higher velocities (0.57 m/s) reduced these values to 35.36 °C and 15.73 °C, respectively. To further improve performance, circular, square, and triangular bar-shaped elements were investigated. The square bar configuration (SA2), with 3 bars spaced 0.1 m apart, achieved the highest efficiency, yielding an outflow temperature of 39.04 °C and a ΔT of 16.06 °C. Reducing the spacing to 0.05 m increased ΔT to 16.45 °C. The inner glazing temperature of 23.3 °C confirmed enhanced heat removal due to increased airflow disruption. These findings underscore the significance of the geometry and placement of internal elements in improving the thermal performance of EAW systems, with configuration SA<sub>2</sub> emerging as the most thermally effective design.</div></div>","PeriodicalId":15064,"journal":{"name":"Journal of building engineering","volume":"114 ","pages":"Article 114283"},"PeriodicalIF":7.4,"publicationDate":"2025-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145254746","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Geopolymers, as green and low-carbon alternatives to Portland cement, offer great potential for sustainable building applications and have therefore attracted broad research interest. The performance of geopolymers is affected by multiple interacting factors, making conventional trial-and-error approaches costly and inefficient. While machine learning (ML) has been widely applied to predict geopolymer properties, purely data-driven models remain limited by black-box behavior, weak generalization, and dependence on data quality. This review systematically examines (i) the applications and dominant algorithms of data-driven ML in geopolymer research, (ii) the underlying reaction mechanisms that inform physically driven strategies, and (iii) the emerging dual-driven frameworks that integrate data with physics. The dual-driven approach represents a novel paradigm that bridges predictive power with mechanistic understanding, offering both accuracy and interpretability. Evidence shows that ensemble learning and deep neural networks achieve the best stability and robustness in data-driven prediction. Incorporating physical insights enhances interpretability and reliability, while hybrid strategies combining both approaches further improve system stability and accuracy. Unlike previous reviews centered mainly on data-driven models, this paper emphasizes the integration of physical reaction mechanisms with ML and highlights knowledge graph–guided pathways as promising directions. Such integration enables closed-loop optimization through knowledge-guided learning, experimental validation, and feedback correction, ultimately supporting the development of a knowledge–data collaboration platform for geopolymers and advancing sustainable material design.</div></div>","PeriodicalId":15064,"journal":{"name":"Journal of building engineering","volume":"114 ","pages":"Article 114227"},"PeriodicalIF":7.4,"publicationDate":"2025-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145270735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, the joint stirrups can be eliminated without significantly affecting the behavior of double-inclined BCJs. As revealed by finite element analysis, the lower joint shear strength of double-inclined BCJs was mainly attributed to the uneven width of concrete strut, resulting in different shear strengths in opposite directions. Moreover, the detrimental effects of column inclination were amplified at higher inclination, while greater column axial loads contributed to higher shear strength of double-inclined ECC BCJs.
