Therefore, design approaches are developed to increase user comfort and reduce energy consumption by utilizing natural ventilation and lighting. The design of the distribution of outdoor air and light into the spaces through vertical and horizontal gaps reduces the energy demand of the mechanical systems and increases occupant comfort. The atrium is the preferred vertical gap in modern buildings for distributing natural air and light to interior spaces under appropriate conditions.  However, in buildings with atrium, there is a risk of fire spreading in the event of a fire due to the uninterrupted gaps between the rooms. It is necessary to ensure the operability of the design by monitoring the measures to be taken in the early stages of design using performance-based fire safety methods. This study develops design strategies for fire analysis in atrium buildings using computational fluid dynamics (CFD) simulation technology. Atrium height, roof type, and slope characteristics are analyzed for the stack effect, which is the main factor in the movement of smoke and flames. As a result of the numerical analyses consisting of flat, unidirectional, and bidirectional sloping roof type, 10, 20, 30-degree roof slope, and one-meter rising atrium roof variables, the effect degrees for smoke dispersal and temperature control are investigated. Fire Dynamic Simulator, which uses CFD capabilities, and Smokeview software, which can visualize the results, were used for the numerical analysis. Correlation analysis was used to determine the effect of variables on temperature. The results showed that flat roofs and designs with increasing height were effective in delaying the spread of smoke and increasing the stack effect in the atrium, while the contribution of roof slope to fire safety was weak.","PeriodicalId":43031,"journal":{"name":"International Journal of Built Environment and Sustainability","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2023-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139153521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, rail projects involve various stakeholders, massive budgets and are susceptible to cost overrun. This paper aims to evaluate the cost influences concerned with rail projects in a developing nation from contractors’ perspectives. The existing studies lack the consideration of the correlation and relationship between the cost influences, which this paper emphasizes. The data collection was performed by distributing questionnaires to 200 cost managers which are quantity surveyors, project managers, and contract executives across the rail projects in Malaysia. The data analysis uses Statistical Package for Social Sciences Version 27 (SPSS V27) and Structural Equation Modelling (SEM). Kaiser-Meyer-Olkin (KMO) measure of sampling adequacy showed appropriate internal consistency of the research instrument, whereas the Confirmatory Factor Analysis (CFA) showed acceptable Goodness-of-Fit Indices (GFI) within the constructs of the structural model. The SEM calibration resulted in 23 significant cost influences which were clustered into five groups of cost influences. Each of the five groups is associated with different parties in construction projects. A notable causative direction was observed in the relationship between the cost influences. Each cost influence can be connected to each project phase based on the PMBOK Guide. This study adds to the various cost management research along the project management of rail construction. It is able to contribute to the policymakers and consultants in strategizing their cost management plans which is crucial, especially in developing countries such as Malaysia. Emphasizing the critical particulars of cost management in rail projects, this paper also delivers its finding based on stakeholder and system aspects in relation to cost management, which can be referred to by any developing country.","PeriodicalId":43031,"journal":{"name":"International Journal of Built Environment and Sustainability","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2023-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139153050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Ho Chi Minh City, the situation has resulted in specific negative urban issues and low life quality for students. This study aimed to clarify how students allocate around a university, the residential zones' characteristics, and preferences for the residential zones. We analyzed survey data of 304 students at a university in Ho Chi Minh City. We addressed the differences among residential zones through statistical analyses of group differences. A multinomial logit model was deployed to explore students' choice of residential zones. Results show significant characteristics that affected the students' choice, including academic levels, motorcycle usage, employment status, family income, household member, household size, and gender. Some implications for policymaking in the student housing market were raised regarding residential zones, integrating transport systems, travel behavior, and employment opportunities. The study enhanced knowledge of the student housing situation (i.e., residential zones or residential allocation) and the student's preferences. Policymakers and practitioners developing student housing markets, built environments, and related services can benefit from this study. The findings apply to the specific city under investigation and are useful to other Southeast Asian cities with similar socio-cultural contexts.","PeriodicalId":43031,"journal":{"name":"International Journal of Built Environment and Sustainability","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2023-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139154262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is expected that kinetic facades will become more common in the future and new geometries are constantly sought. Kinetic Reciprocal Frame (KRF) structures are also one of the innovative and sustainable approaches. In this study, KRF structures are used as adaptive facades and are analyzed in two stages. As a test model, a standard high-rise office building in Ankara, Turkey is created and simulations are made on the south facade. In the first stage, the modules’ applicability in different geometries is examined and the differences within the geometries are revealed. KRF modules are examined for cost-effectiveness and mobility. In the second stage, analyzes are made on the daylight performance of the geometries. Modules are evaluated based on spatial daylight autonomy (sDA), annual sunlight exposure (ASE), and average lux. As a result, in terms of daylight performance, the hexagonal KRF module gives the best result by drawing the most homogeneous values due to its high mobility. However, it is noticed that the daylight performance of the triangle KRF module is weak compared to other modules, the ASE values cannot be controlled and it is more difficult to implement because it is not effective in terms of cost per module. The fact that hexagonal modules give good results in terms of cost is found to be good in support of it. This study is also valuable study in terms of the application performance of KRF structures on the facade.","PeriodicalId":43031,"journal":{"name":"International Journal of Built Environment and Sustainability","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2023-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139154704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Today, as the importance of sustainable architecture has increased, architectural approaches that are compatible with nature have been adopted and thus the protection of natural life has been tried to be supported. As a definition, sustainability is a form of practice that aims to harmonize the built environment with natural life. In this context, the impact on animals whose habitats we are destroying is a significant topic within sustainability discussions. Studies show that the role and importance of human-animal based sustainable architectural habitats for enhancing animal welfare have not been extensively investigated. This study aims to discuss the importance of animal-aided designs within the sustainability approach. In addition, it is to carry out studies to improve the quality of life in society by strengthening the human-animal bond. In line with this purpose, animal-aided designs at urban, infrastructure, and building scales were analyzed within sustainability approaches, and their contribution to the sustainability approach was evaluated. As a result, it is emphasized that the sustainable animal-aided design approach provides innovative solutions for structures to be designed for animals and it also contributes to environmental, social, and economic sustainability, but in order for these designs to be successful, it is underlined that living spaces suitable for the needs of animals should be created and the negative effects of environmental impacts on animals should be considered. It is also emphasized that in addition to the principles of sustainability, factors that pay regard to the lives of animals contribute to the understanding of sustainability. It is expected that the discussion of the relationship between sustainability and animal-aided design, which is put forward through this study, will create an important discussion ground for future research and application examples.","PeriodicalId":43031,"journal":{"name":"International Journal of Built Environment and Sustainability","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2023-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139154125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These background variables could assist in arriving at emerging themes, problems and gaps for concrete windowless office development in Malaysia. In this systematic review, the bibliographic information of title, abstract and keywords was mined from 255 documents on the Scopus database to generate scientometric maps and links showing relationships on co-authorship, co-citation, co-occurrences, and bibliometric coupling. The top trending variables in windowless office research are COVID-19, energy efficiency, indoor air quality, heart rate variability, performance assessment, visual reality, and workplace environment. Like other advanced economies in Asia, Malaysia is seen to attain a satisfactory level of development to implement the windowless office design module, with stable electricity power, technological advancement, and psychological stability of the people.

Hence, the present study aims to identify the hotspot regions of extreme heat within the Malappuram urban agglomeration region and suggest strategies for its improvement. The split-window algorithm retrieved land surface temperature (LST) for 1991, 1998, 2014, and 2020 using Landsat 5 ETM and Landsat 8 satellite imageries. A rising trend in LST has been detected in the last 30 years, and the mean value has increased by 1.70°C within the region. Among the selected hotspots, an LST increase of 1.84°C was observed for those areas with the highest increase in urban density with decreased vegetation. The increasing impact of urbanization and the subsequent change in land use patterns at the cost of greenery have caused a substantial effect on the local climate. Accordingly, planning and policy directions are proposed for the local government that can help provide awareness to the people through the effective implementation of mitigation measures.","PeriodicalId":43031,"journal":{"name":"International Journal of Built Environment and Sustainability","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2023-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43184213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Different user groups cannot find answers to some of their physical and social needs in this housing and its surroundings. This circumstance generates socially unsustainable regions. From this point of view, the study seeks answers to the questions \"What is the social sustainability satisfaction level of the users?\" and \"Is there a statistically significant difference between the social sustainability satisfaction levels and the different characteristics of the users in the existing mass housing areas?\" So, the study reveals the criteria necessary for ensuring social sustainability, defines the level of satisfaction with the fulfillment of these criteria, and determines the statistical difference in satisfaction based on resident characteristics. The link between housing and social sustainability was evaluated using the criteria of social equity and sustainability of community. 87 residents filled out the questionnaire form in a mass housing complex in Istanbul. Researchers used descriptive statistics, the Mann Whitney-U, and the Kruskal-Walis tests to define the statistical difference between social sustainability parameters and the demographic characteristics of the residents. The analysis revealed that inclusion and spatial diversity satisfaction on the housing scale were at the highest level and satisfaction with the Participation criteria was at the lowest level in ensuring social sustainability. The results of the Mann-Whitney U and Kruskal-Wallis tests are as follows: The spatial diversity satisfaction differed in terms of education, economic status, housing type, and length of residence; the social diversity satisfaction differed in terms of gender and age; and the accessibility sub-criterion differed in terms of gender. Only social interaction satisfaction differed by gender, education, and employment status among the sustainability of community criteria. The satisfaction of inclusion, security, community stability, sense of place, and participation were unaffected by demographic characteristics.","PeriodicalId":43031,"journal":{"name":"International Journal of Built Environment and Sustainability","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2023-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46399174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
