Passive solar heating strategies reduce heating demand by utilizing solar energy. However, their effectiveness is limited during daytime. Phase change materials (PCMs) offer a solution by storing heat during the day and releasing it at night. To maximize PCM effectiveness, optimizing PCM placement, melting temperature, and thickness is essential. This study designs and evaluates a passive heating system for two room cases in a residential building in Seoul: a single-exposed (one exposed wall) and a corner-exposed room (two exposed walls). EnergyPlus simulations assess various interior placements, melting temperatures (21 °C–29 °C), and thicknesses (5 mm–40 mm). Results showed that placing PCM on the floor, where solar irradiance is the highest, achieved the greatest total load reduction—15.2 % in the single-exposed room and 11 % in the corner-exposed room. However, in the presence of a radiant floor heating system, west-wall placement avoided heat interference with the radiant system, reducing total energy supply by 12 % and 10 %, respectively. The optimal PCM thickness for heating load reduction was 17.5 mm and 20 mm, while total load reduction plateaued at 17.5 mm for both rooms. During intermittent seasons, overheating increased in the single-exposed room but decreased in the corner-exposed room, highlighting the influence of room placement on PCM performance. The proposed PCM-based passive heating system demonstrated significant potential for energy savings and thermal regulation, supporting its effectiveness in improving heating efficiency across indoor conditions.</div></div>","PeriodicalId":15064,"journal":{"name":"Journal of building engineering","volume":"111 ","pages":"Article 113156"},"PeriodicalIF":6.7,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144291674","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}

In particular, two configurations of NPTMDIs (designated as NPTMDI I and II) are firstly proposed by introducing nonlinearly arranged inerter (NPTMDI I) and clutched inerter (NPTMDI II), respectively, and corresponding analytical models are established. Then, dynamic equilibrium equations of motion of NPTMDI I and II are derived, respectively, and a two-stage optimization scheme is formulated. Based on the optimal parameters, the control effectiveness of NPTMDI I and II are investigated, and compared to that of the traditional PTMD. Finally, case studies are performed to further investigate the control effectiveness of the proposed NPTMDIs in reducing the seismic responses of a 40-storey benchmark building model. The results demonstrate that, compared to the traditional PTMD, the proposed NPTMDIs (especially Configuration I) are more effective in concurrently reducing both the displacement and acceleration responses of the structures.

This study examines the impact force profile of RC shear walls subjected to out-of-plane impacts through three-dimensional finite element numerical modeling. The effects of cross-section stiffness, overall stiffness (by changing the wall’s thickness and height) and drop-weight-to-wall mass ratio on the profile were analyzed based on a total of 64 numerical models. The results reveal that the peak impact force increases as the cross-section stiffness rises. As the overall stiffness decreases, the plateau force decreases and the duration is prolonged. The rise in impact mass makes the plateau force and the plateau duration rise. Variations in the impact mass-to-wall mass ratio significantly alter the time-history curves of impact forces. Numerical simulations identify three characteristic patterns for out-of-plane impacted RC shear walls: single-peak, double-peak, and peak-plateau configurations. Through strategic identification of characteristic points, empirically derived formulas were established to predict impact force profiles, with predictive validity confirmed through rigorous comparisons with experimental datasets and computational results.</div></div>","PeriodicalId":15064,"journal":{"name":"Journal of building engineering","volume":"111 ","pages":"Article 113146"},"PeriodicalIF":6.7,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144297672","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}

Additionally, Grad-Absolute-CAM exhibited superior consistency in local explanations. An ablation study was conducted based on the feature importance rankings provided by the four XAI methods. Through comprehensive comparison, the 11 most influential features for energy consumption prediction were identified.
