The geometry is the combination of fixed-shape tetrahedrons with non-fixed-shape pentahedrons and hexahedrons that allow the creation of a diversity of soft architectural forms based on uniform-length pipes. By only changing the joints set, the user can change the entire architectural form to adapt to a new site or to accommodate a new requirement when moving or renovating.

JAR's overarching objective is to disseminate the latest research results on architecture in Japan to academia worldwide. JAR is a unique journal, covering a wide and complex range of architectural studies, including the latest trends in architectural technology and architectural and design trends in Japan.</p><p>The choice of the name “Japan” for this journal's title reflects two major aspirations. One is the “Japan” of the AIJ, and the other is the strong focus on information dissemination from Japan to the world. JAR has a unique purpose and management structure, specializing in the dissemination of information from Japan to the world, rather than expecting papers to be submitted from all over the world. JAR accepts the risk of a limited number of contributions and publications; however, it supports the development of architectural engineering and sciences in Japan.</p><p>Eight years after its launch, JAR is steadily growing and obtaining recognition in architectural academia worldwide. The number of paper submissions has steadily increased. Although the majority of submissions were translated papers when the journal was first published, the number of original submissions has exceeded the total number of editions. To appropriately respond to the increase in submissions and contributions from diverse fields of architecture, the Editorial Board was strengthened in 2025. Satoru Takada (Kobe University) will join as AE in the environmental field, and Taishi Watanabe (Waseda University) and Kozo Kadowaki (Meiji University) will join in the design field. Koichi Yasuda (Institute of Science Tokyo) has moved to become an Honorary Editorial Advisory Board Member, and Shin-ichi Tanabe (Waseda University) stepped down from the EIC to concentrate on AE in the environmental engineering field, with Kazuhide Ito (Kyushu University) taking sole charge of the EIC.</p><p>Since 2018, JAR has awarded the Best Paper Award to the most outstanding and qualified papers. This year, JAR Editors-in-Chief (EICs) and Associate Editors (AEs) conducted a rigorous and thorough review of the papers published in 2024. We are excited to announce the winners of the 2024 Best Paper Award. All 52 papers published in Volume 7, Issue 1, 2024, were considered for the award. These papers were thoroughly evaluated following the guidelines, and the EICs and AEs decided the winners after considering the following: “high-quality content at an international level,” “exploration of new areas, methodologies, and concepts,” “abundant originality, pioneering achievement, and novelty,” and the “potential and outstanding accuracy, diligence, and effort” of the nominees, along with the review comments for the papers.</p><p>Hence, the 2024 Best Paper Award goes to:</p><p>Kun-Sian Lin, Masahiro Kurata, Yutaro Kawasaki,","PeriodicalId":42793,"journal":{"name":"Japan Architectural Review","volume":"8 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2025-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/2475-8876.70048","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144810983","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}

In this paper, we examine a hot water supply preheating system that utilizes unused wells in traditional Japanese houses. In this system, the pipe supplying water to the water heater passes through the well water and is preheated by heat exchange with it. We show the results of measuring the well-water temperature in an actual well for a period of 1 year and propose a method for estimating the well-water temperature. Furthermore, we show the results of a heat exchange experiment in the actual well and propose a method for estimating the temperature change of water passing through a coil used for the heat exchange. Finally, using methods of estimating the well-water temperature and the temperature change of water passing through the coil, we estimate the rates of reduction in energy needed to supply hot water via this system when the preheated water supply is heated to 50°C–60°C by this system, as opposed to the case where the unpreheated water supply is heated to 50°C–60°C.

The pre-renovation unit featured a 2K layout, a 40.5 m² floor area, and a monthly rent of 71 000 yen—specifications that did not align with the typical needs of any household type, potentially leading to vacancies.

The estimated monthly rent before renovation was 69 904 yen, while the expected rents after renovation were 72 741 yen (1DK) and 80 917 yen (1LDK).

Although urban trees have a cooling effect, this effect must be evaluated quantitatively for effective landscape and streetscape design. However, models capable of predicting hourly changes in typical tree transpiration under summer conditions at the whole-tree scale rather than the individual-leaf or forest scale are lacking. In addition, leaf surface temperatures in the lower canopy, which significantly affect the radiative environment of pedestrians, must be accurately predicted. Nevertheless, the prediction accuracy of heat balance changes on leaf surfaces due to transpiration has not been adequately validated. Such models must also consider plant physiological responses, which vary with the surrounding physical environment, to ensure high accuracy. In this study, a literature review was performed to identify transpiration and stomatal conductance models that can predict typical transpiration and heat balance properties. Subsequently, hourly transpiration rate changes of the whole tree and spatial distribution of leaf surface temperatures in the lower canopy were measured. The parameters of the stomatal conductance model were also estimated to enable predictions using both models combined. The present model is novel because it reproduces whole-tree transpiration rate characteristics and leaf surface temperature trends in the lower canopy.</p>","PeriodicalId":42793,"journal":{"name":"Japan Architectural Review","volume":"8 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/2475-8876.70042","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144666403","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}
