However, the plastic behavior of these members, particularly the yield, buckling, and ultimate strengths under various boundary conditions, remains insufficiently investigated. Unlike straight members, curved members lack well-established design equations and connection design guidelines, limiting their use for earthquake-resistant applications. This study investigated the plastic behavior of curved members through static analysis and extensive parametric studies, focusing on initial elastic stiffness, plastic strength, slenderness effects, and section compactness. Estimation equations for yield strength and buckling behavior with pinned- and fixed-boundary conditions were developed and validated using numerical simulations, demonstrating high accuracy. The findings further contributed to developing a connection design methodology that enhances material efficiency while preventing overly conservative designs. Moreover, a boundary constraint condition was identified to effectively control the yielding mechanism and achieve the desired plastic behavior. The proposed estimation equations and design recommendations provide a foundation for the practical implementation of curved members in seismic applications, improving structural efficiency, design flexibility, and functionality.","PeriodicalId":42793,"journal":{"name":"Japan Architectural Review","volume":"9 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2026-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/2475-8876.70069","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146099451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their large thermal mass enables peak load shifting, making them suitable for demand response (DR). Effective DR control requires methods that can flexibly handle dynamic building behavior, disturbances, and varying thermal characteristics. While model predictive control (MPC) is capable of predictive optimization, conventional MPC relies on fixed models and lacks adaptability to time-varying system conditions. This study introduces an adaptive MPC (AMPC) method, which incorporates online estimation and sequential model updating, to realize a DR-based control strategy for TABS. The method was evaluated through a co-simulation framework using Dymola and MATLAB/Simulink. Results show that AMPC can perform effective precooling and stably respond to DR requests. Through multiple case studies, the method was found to leverage the thermal storage capacity of TABS to flexibly shift cooling loads. Under the examined conditions, approximately 90%–100% of peak cooling energy was shifted to off-peak periods, while ceiling surface temperature errors were maintained within about 0.3°C. Furthermore, PMV remained within ±0.5 in all cases, demonstrating that thermal comfort can be preserved even under restricted cooling operation.","PeriodicalId":42793,"journal":{"name":"Japan Architectural Review","volume":"9 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2026-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/2475-8876.70068","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146007884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fieldwork included legal document analysis, stakeholder interviews, and full-day observations to identify usage and governance patterns. Ilānanī and Sasunanī are public land owned by the government, while Kwābahā is privately owned by its Saṃgha organization. The courtyards function differently: Ilānanī supports residential life, religious activity, tourism, commerce, and transit; Sasunanī is mainly residential and communal; Kwābahā serves as a religious and touristic centre, houses the priest's family, and provides a public resting space. These findings highlight the evolution of courtyard spaces in historic Patan into multifunctional communal areas. Despite differences in ownership, all three continue to serve as shared environments, balancing traditional religious and residential roles with new socio-cultural functions shaped by urban transformation.","PeriodicalId":42793,"journal":{"name":"Japan Architectural Review","volume":"9 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2026-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/2475-8876.70061","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146016322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The drift-flux model is first validated against a benchmark particle dispersion experiment, showing good agreement with measured velocity and concentration. Simulations are then conducted for an L-shaped room equipped with ceiling ventilation and a portable air cleaner placed at four locations. Particles ranging from 1 to 50 μm (particle density: 1.6 × 103 kg/m3) are considered uniformly generated. The relative contributions of ventilation (air change rates (ACH) of 0.5 and 2), air cleaner intake (ACH of 3.15), and gravitational settling are quantified. Results show that the air cleaner dominates removal for particles smaller than 10 μm, whereas gravitational settling governs particles larger than 10 μm. Considering no surface deposition or resuspension, the cleaner placement minorly influences overall removal efficiency. A one-node model based on an equivalent ACH framework is proposed to compare its predictions with CFD results. Although the one-node model cannot represent spatial variations, it captured overall trends in particle removal. This study provides insights for evaluating particle removal strategies and optimizing air cleaner use in indoor environments.","PeriodicalId":42793,"journal":{"name":"Japan Architectural Review","volume":"9 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2026-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/2475-8876.70067","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145904640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study presents a framework that combines Gaussian Process Regression (GPR) models with an exhaustive search method to improve HVAC operation. The models were trained on Building Energy Management System (BEMS) data, with key features selected using the RReliefF algorithm. The GPR models achieved high prediction accuracy, with an RMSE of 0.22°C and R2 of 0.813 for indoor temperature, and an RMSE of 34.45 ppm and R2 of 0.919 for CO2 concentration. For operational improvement, the supply air volume of the Dedicated Outdoor Air Handling Unit (DAHU) was adjusted to maintain CO2 concentration near 700 ppm, while the supply air temperature of the Air Conditioning Unit (ACU) was controlled to keep indoor temperature between 26°C–27°C. These adjustments reduced fluctuations and lowered mean values, confirming improvements in both thermal comfort and IAQ. The proposed method requires no additional sensors or complex physical models, and its low computational cost ensures feasibility on standard PC environments. Overall, the results demonstrate that combining GPR-based prediction with exhaustive search enables simultaneous enhancement of thermal comfort and IAQ, with practical applicability verified using real BEMS data.","PeriodicalId":42793,"journal":{"name":"Japan Architectural Review","volume":"9 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2025-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/2475-8876.70065","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145887551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Following stratification of the psychological stress status, logistic regression analysis was performed by adopting the environment of a personal workspace at baseline as an independent variable and work engagement in the follow-up as a dependent variable. In the low psychological stress group, the respondents who assessed their workspace to be enclosed demonstrated a work engagement level 2.07 (95% confidence interval [CI]: 1.24–3.48) times higher than those who assessed their workspace as open. In the high psychological stress group, the odds ratio for the participants who had frequent work-related conversations in a personal workspace was significantly higher at 3.92 (95% CI: 1.23–12.51) than for those who had a low frequency of conversation. Workplaces should achieve a balance between promoting both concentration and communication.

In the absence of formal planning and infrastructure, road spaces—particularly residential streets and a main thoroughfare—function as the primary venues for daily interaction, economic activity, and community life. Based on field observations, structured questionnaires (70 groups, 189 individuals), and pedestrian count data, the study analyzes interaction patterns across five dimensions: group scale, spatial proximity, nature of neighborhood relationships, degree of social mixture, and level of economic activity. The findings reveal that residential streets foster diverse, cross-cutting interactions among residents of varying gender, ethnicity, religion, and origin, while the main street is characterized by more homogeneous, identity-based groupings, often tied to shared origin or kinship. This contrast reflects underlying residential patterns and economic functions. By highlighting the differentiated roles of public spaces in socially complex environments, the study contributes to a deeper understanding of how informal communities negotiate coexistence. It argues that acknowledging these spatial–social dynamics is essential for inclusive upgrading strategies and the design of shared urban spaces in informal settlements.","PeriodicalId":42793,"journal":{"name":"Japan Architectural Review","volume":"8 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2025-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/2475-8876.70062","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145751088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The temporal resolution of weather data can influence the outcomes of simulation-based design and operational decisions. This study examines the impact of weather data temporal resolution on building energy and daylighting simulations. EnergyPlus is employed as the BPS engine to compare the effects of different temporal resolutions, hourly, 5-min, and 1-min weather data, on simulation accuracy, and to contrast simulation outcomes using high-resolution weather data with conventional hourly data. The results show that the resolution of weather input data has only a slight impact on annual energy consumption for heating, cooling, and lighting. However, significant discrepancies emerge at the daily level, especially during periods of rapidly changing sky conditions. The study highlights the value of high-resolution weather data for performance modeling in buildings that use responsive shading or window control systems. Most notably, on partly cloudy days, shading control performance differed by approximately 8% when comparing simulations using 1-h weather data to 5-min or 1-min data. This indicates that hourly data fails to capture rapid fluctuations in solar radiation under variable sky conditions. For applications involving dynamic controls, finer temporal resolution is essential for reliable simulation.","PeriodicalId":42793,"journal":{"name":"Japan Architectural Review","volume":"8 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2025-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/2475-8876.70059","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145750735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
