Due to the close connection between urban cluster and carbon emissions (CEs) but a lack of study on it of the construction industry, this paper aims to explore the relationship between the polycentric spatial structure (PSS) of the urban clusters and CEs of the construction industry (CECI).

This research uses panel data of 10 Chinese urban clusters from 2006–2021, calculates their PSSs in the aspects of economy and employment and adopts a panel regression model to explore the effect of the spatiotemporal characteristics of the PSSs on the CECI.

First, the CECI in 10 Chinese urban clusters showed a rising trend in general, and the CECI in the Yangtze River Delta (YRD) was much higher than those in the rest of urban clusters. Second, both Shandong Peninsula (SP) and Guangdong-Fujian-Zhejiang (GFZ) exhibited high degrees of polycentric characteristics, while Beijing-Tianjin-Hebei (BTH) showed weaker degrees. Third, the results demonstrated that the polycentric development of urban clusters did not help reduce the CECI but rather promote the CE. The polycentric index, considering the linear distance from the main center to sub center, had a more significant impact on the CECI.

Previous studies have investigated the impact of urban spatial structure (USS) on CEs; however, few of them have studied in the field of construction industry. Moreover, most research of CEs have concentrated at the national and provincial levels, with fewer studies on urban clusters. This paper contributes to this knowledge by investigating how the PSS of urban cluster influence the CECI.

This paper offers a unique perspective on the urbanisation process in developing cities, with a particular focus on the region of the Gulf States. Beyond economic considerations, the analysis sheds light on the complex interplay of socio-cultural factors, gender dynamics and urban development. Based on the calls for human-centred approaches to rethinking urban design and management of cities require the integration of these cities’ inhabitants’ lived experiences, that impact residents’ daily lives. The focus is on the importance of women’s perspectives in the development process.

The paper uses a systematic literature review that builds on existing knowledge relating to urbanisation, modernisation, sustainable cities, gender and the Arabian Gulf. It uses Lefebvre’s 'right to the city' theory to understand the evolution of the Gulf Cities which is a novel approach. This adaptation offers a unique perspective on the transformations and challenges that these urban spaces face. Furthermore, it offers a firm foundation for developing advanced knowledge on the interdisciplinary nature of the topic discussed and assists in integrating empirical findings and perspectives from different resources.

The extreme levels of transformation in urbanisation in the Gulf States built cities that are no longer solely places for settlement, production and services but operate as significant influencers on the social, economic and political relations that produced design and cultural challenges. These cities became epicentres of power and politics that shaped the national visions and influenced policy. The process of inclusive and considerate urban development that the Arabian Gulf region is aiming to embark on is not a new exclusive strategy. But a process that has been implemented and tested in other urbanised areas globally.

Very little historical urban research on the Arabian Gulf countries exists, hence, the difficulty in researching the Gulf urbanisation process or providing historical encounters of the change.

This paper delves into the gendered aspects of urban planning, an aspect that is frequently overlooked. It contributes to the discourse on gender inclusivity in urban spaces by focussing on Khaleeji women’s experiences, offering insights that go beyond economic considerations. The use of Lefebvre’s “right to the city” theory to understand the evolution of the Gulf Cities is a unique approach. It investigates the interaction of various factors such as economic, cultural and political influences on Gulf urban development. This adaptation offers a distinctive perspective on the transformations and challenges that these urban spaces face.

The UNESCO recommendation under the historic urban landscapes (HUL) title and Operational Guidelines (OPG) were used to create dynamic protective boundaries to maintain the integrity and authenticity of Isfahan's heritage waterways. Accordingly, by using GIS and Isfahan urban layers, three protective zones were proposed and evaluated; the central zone, the functional zone and the visual zone.

Heritage waterways in historic cities are not adequately protected against the negative impacts of urban development, and there is a lack of a dynamic protective system to protect their integrity and authenticity. The problem can be observed in Isfahan, a historic Iranian city, where the boundaries of urban heritage waterways (Madi canals) are usually rigid and arbitrary. This study aims to develop a practicable paradigm for determining protection boundaries for Isfahan's Jolfa Madi, an urban heritage waterway.

Compared to the current protective boundaries, the authors found that proposed protective boundaries create a greater amount of protection space, which makes a strong connection among the ecological, historical and socio-economic characteristics of the urban context. Furthermore, the protective zones based on the HUL approach give Isfahan's urban planning policy the opportunity to consider participatory tools, financial tools and regulatory systems.

Many studies have emphasized a fixed-width buffer or an arbitrary distance from the urban waterway's axis (urban heritage) or its banks. Although these protections include technical conservation or setting restrictions on the adjacent buildings and blocks, studying crucial concepts such as urban dynamic, urban heritage context and producing a particular technique for protected boundaries has not been investigated. In this article three dynamic boundaries are delineated with various functions in order to provide urban heritage with dynamic preservation and sustainable development for the historic urban landscapes.

This study aims to test the effect of Seattle’s discontinuous sidewalk requirement, on the number of housing units per construction permit.

This study uses discontinuity linear regression (DLR) on a database of Seattle’s housing construction permits during January-2015 to January-2018, controlled by 51 socioeconomic, planning and geographic variables. The sidewalk requirement is continuous inside the designated urban villages; however, it is spatially and quantitatively discontinuous in the rest of the city: certain blocks at certain locations require sidewalks’ design and construction in permits with six or more housing units. DLR detects the effect of the discontinuity while controlling for a vast array of confounding variables.

The primary finding is that the discontinuous requirement reduces the number of housing units in about 75% of a housing unit per permit, which at the aggregate level amounts to around 335 fewer housing units during the period of analysis.

The database is relatively small, which has limited a more thorough specification process and robustness tests.

Besides directly testing the effect of a discontinuous in-kind development contribution, the research setup allows to discuss a wider, more structural problem: the possibility of contributions avoidance due to spatial substitution. In contrast, spatially continuous (i.e. city-level) contributions cannot be avoided by performing spatial substitution, and they are internalized by the housing supply side (market-neutral).

Faced with the growing need to find new viable water supply models for urban areas, this article studies and maps the strategies and identifies the key criteria of sustainable development present in pioneering water supply systems in the medieval period. The main aim is to determine which of its innovative principles could be applied in present-day cities.

From a methodological perspective, two types of cases were established, such as water supply models for human consumption and pre-industrial hydraulic systems, all of which are located in Italy. For the first group, the cases of Venice and Siena were analysed, while for the second, in the context of the cities along the Aemilian Way, the case of Bologna was selected.

Five key criteria resulted from the analysis of the cases: exploitation, self-sufficiency, maintenance, rationalisation and reuse. The said concepts were defined and contextualised within the framework of the Sustainable Development Goals.

The Middle Ages were a historic moment in technological reinvention, before the development of modern systems of sanitation. With very limited resources, these traditional systems focused on rational use and deep cultural and geographical knowledge. This is why its recognition is of great importance today, in a time full of instabilities, with a view to the work that needs to be done for the development of more sustainable communities.

Comfortable outdoor workspaces are important for employees in business parks and urban areas. Prioritizing a pleasant thermal environment is essential for employee productivity, as well as the improvement of outdoor spaces between office buildings to enhance social activities and quality of outdoor workplaces in a hot arid climate has been subjected to very little studies Thus, this study focuses on business parks (BPs) landscape elements. The objective of this study is to enhance the user's thermal comfort in the work environment, especially in the outdoors attached to the administrative and office buildings such as the BPs.

This research follows Four-phases methodology. Phase 1 is the investigation of the literature review including the Concept and consideration of BP urban planning, Achieving outdoor thermal comfort (OTC) and shading elements analysis. Phase 2 is the case study initial analysis targeting for prioritizing zones for shading involves three main methods: social assessment, geometrical assessment and environmental assessment. Phase 3 entails selecting shading elements that are suitable for the zones requiring shading parametrize the selected shading elements. Phase 4 focuses on the optimization of OTC through shading arrangements for the prioritized zones.

Shading design is a multidimensional process that requires consideration of various factors, including social aspects, environmental impact and structural integrity. Shading elements in urban areas play a crucial role in mitigating heat stress by effectively shielding surfaces from solar radiation. The integration of parametric design and computational optimization techniques enhances the shading design process by generating a wide range of alternative solutions.

While conducting this research, it is important to acknowledge certain limitations that may affect the generalizability and scope of the findings. One significant limitation lies in the use of the shade audit method as a tool to prioritize zones for shading. Although the shade audit approach offers practical benefits for designers compared to using questionnaires, it may have its own inherent biases or may not capture the full complexity of human preferences and needs.

Few studies have focused on optimizing the type and location of devices that shade outdoor spaces. As a result, there is no consensus on the workflow that should regulate the design of outdoor shading installations in terms of microclimate and human thermal comfort, therefore testing parametric shading scenarios for open spaces between office buildings to increase the benefit of the outer environment is very important. The study synthesizes OTC strategies by filling the research gap through the implementation of a proper workflow that utilizes parametric thermal comfort.

This article explores the migration intentions (MIs) embedded in population movements from rural to urban areas in Bangladesh. In this country, urban-centric development policies have made cities epicentres of commerce and industrialisation, offering significant employment and livelihood opportunities. This rapid transformation has generated several socio-psychological factors that are influencing the willingness of rural populations to migrate to cities for better jobs, lifestyles and services.

The present study adopted the theory of planned behaviour (TPB) as a conceptual model to assess the behavioural and psychological factors underlying MIs.

The results of the structural equation modelling (SEM) indicate that MIs are mainly influenced by subjective norms (SN) and, to a lesser extent, attitudes towards migration (ATM) and perceived behavioural control (PBC).

The analysis drew on an original dataset built through interviews with migrants from rural areas employed in the ready-made garment (RMG) industry in four selective areas of the Metropolitan City of Chittagong.

The purpose of this study is to use a lifetime income measure to evaluate the long-run housing affordability for an understudied cohort of households in the literature – the millennials. The authors do this in the context of Malaysia, measuring long-run affordability for four housing types across geographic locations and income distributions.

This study calculates a long-run housing affordability index (HAI) using data on house prices and household incomes. Essentially a ratio of predicted lifetime incomes to house prices, the HAI is computed for four common housing types in Malaysia from 2005 to 2016 and for six states in the country. The HAI is also compared across four income percentiles.

The analysis reveals varying patterns of housing affordability among different states in Malaysia. Housing affordability has declined since 2010, with most housing types being unaffordable for millennial-led households with the lowest income. Housing is most affordable for those in the highest income bracket, although even here, there are pockets of unaffordable housing as well.

Based on the findings, this study proposes three targeted interventions to improve housing affordability for Malaysian millennials.

This study fills a gap in the literature by examining the long-run housing affordability of Malaysian millennial-led households based on both geographic location and income distribution. The millennial population is understudied in the housing affordability literature, making this study a valuable contribution to the field.

This paper is intended to assess the developments conducted on the master plan of Old Najaf, mainly in three areas: the Imam Ali Holy Shrine and its surroundings, the Great Market Area and the location of the Town of Visitors.

In order to analyse the implementation of the transformation phases in Old Najaf, the Strengths, Weaknesses, Opportunities, and Threats (SWOT) technique was used to identify and organise the strengths, weaknesses, opportunities and threats related to the examined case study of the city's historic centre. At the first stage, all available data (photographs, maps, documents and reports) were collected from different sources, including previous studies by governmental institutions, departments and agencies. Ultimately, the SWOT analysis was used for each identified phase in the morphological evolution of the historic centre. This can offer an opportunity to observe the implications of urban planning practices in Old Najaf from the mid-20th century to the present day. In order to identify the well-organised urban design practices and appropriate strategies, the implemented studies and projects were examined by the four factors of the SWOT analysis.

The current results have revealed important urban transformations, already made and/or ongoing, of those aforementioned three main areas, which imply a great loss of the city's traditional character and urban heritage. Further, the environmental and socio-economic issues should be involved in the analysis to evaluate how they have influenced the current outcomes of Old Najaf in relation to the urban configuration and orientation.

The rich cultural and architectural heritage of Al-Najaf historic centre is dramatically neglected and seriously threatened to be lost. Hence, conservation on both tangible and intangible levels is urgently needed. It is the first paper which focussed on this problem and tries to learn from the British Conservation Experiences in this field.

This study defines and critically analyzes Korean high modernism using the Sewoon Sangga project as a case study, as it has significant value in Korea's urban and architectural history.

The methodology applied for this study was a theory-interpretive analysis. This study examines the modernization process of Seoul based on the concept of “high modernism,” in that the theory-interpretive analysis method analyzes historical phenomena centered on a specific concept.

As a form of national belief, the various ideas that give birth to modern cities are defined as “high modernism.” As a Korean megastructure, the Sewoon Sangga project is significant in the history of Korean urbanism and architecture because it is the archetype of Korean high modernism and is representative of South Korea's compressed economic growth. However, soon-to-be-demolished Sewoon Sangga signifies the failure of Korean high modernism. This study identified the critical characteristics of Korean high modernism through the Sewoon Sangga project.

This study analyzed a representative Asian city through the specific concept of high modernism. It transpired that high modernism, which played an important role in the birth and development of modern cities, should be transformed for future cities and architectural development. This study has significance in that it expands the study of the history of urbanism and architecture centered on the West to the same in Asia.
