Urban planning in post-industrial cities is often limited by stakeholders’ understanding of the potential for intensifying mixed industrial and cultural uses, and the benefits to each of their co-location. In Brussels, differences in language and governance pose additional challenges to actors trying to bring together diverse stakeholders to cooperatively plan for urban regeneration. As part of a wider action research project on regeneration of the city, five co-design workshops were held across Brussels in 2017–2019 and interviews with participants were conducted. Later, in 2023, the researchers returned to the city to assess the practical outcomes of the project. This paper explores the role of the workshops in harnessing the untapped potential for integrating and expanding mixed industrial and cultural uses, and highlights the factors required to inspire and motivate diverse stakeholders to drive sustainable innovation and growth.

China has entered a period of urban renewal, with the focus shifting from large-scale incremental construction to both upgrading existing building quality and adjusting incremental structures. There are three main types of urban renewal: demolition and reconstruction, comprehensive improvement, and organic renewal. The latter systematically optimizes and enhances urban functions, spaces, and culture through gradual renovation methods and is, therefore, suitable for use in ancient cities. To promote organic renewal, the problem of limited space resources must first be addressed, which can be resolved to a certain extent by the moderate development of underground spaces; preliminary evaluations of the development potential are also required. In consideration of the demands of organic renewal, we constructed a novel indicator system for evaluating underground space development potential (USDP) in ancient cities that assesses two dimensions: development demand and development suitability. A multi-factor comprehensive evaluation method was adopted to quantify the indicators of USDP, taking Shaoxing Ancient City (SAC) as the case study. According to the USDP evaluation, SAC can be divided into four kinds of areas: high-potential, general-potential, low-potential, and prohibited development areas. High-potential areas accounted for 16.38% of the total evaluation area and were primarily concentrated in or near key locations: train transit stations (Shaoxing Railway Station), public service facilities, evacuated land, and cultural and tourism facilities around historic districts (Shusheng Guli Historical and Cultural Street). The proposed development strategies for these areas included the interconnection of metro stations, redevelopment of relocation-related and vacated land, construction of underground cultural corridors, and supplementation of parking facilities. For developed underground spaces with low utilization efficiency, functional renewal and management improvement measures were put forward. Our method of evaluating the USDP of ancient cities and the strategies proposed to optimize the utilization of underground space can provide reference examples for SAC and other similar ancient cities.

This study addresses inadequate natural ventilation in low-rise residential areas of Bangi-dong, Seoul, where 46.2% of the area experiences wind stagnation below 0.3 m/s due to buildings being spaced less than 2 m apart. Using SimScale CFD with LBM and 13 million grids, multiple urban configurations were simulated to analyze how building orientation, spacing, and height affect pedestrian-level (1.5 m) wind flow. Results show that simple open space expansion yields minimal improvement (5–7%), while strategic interventions achieve significant effects. Connecting open spaces to main roads via 35 m × 45 m corridors increases wind speed by 20.4%, perpendicular building orientation with 12-story buildings improves wind speed by 166.67%, 6 m building spacing enhances ventilation (with a 57.80% improvement), and a continuous 12-story building arrangement along roads achieves a 59.73% improvement. While statistical validation requires future field measurements, the significant improvements (17–167%) demonstrate clear practical benefits. The study proposes four design guidelines: prioritize open space-road connectivity; orient buildings perpendicular to prevailing winds (WNW) with 6 m spacing; implement selective high-rise development (8–12 stories at ventilation nodes); and adopt incremental redevelopment strategies. These findings demonstrate that significant environmental improvements are achievable without costly total redevelopment, providing a replicable model for similar high-density, low-rise areas. The research contributes by establishing a quantitative framework for assessing low-speed wind stagnation zones, previously overlooked in wind environment standards. Full article

The knowledge economy has become ever more important for cities and regions, and different types of urban spaces have been created to accommodate its activities. One of the main assets of these spaces is vitality, a quality that is directly related to innovation and is oftentimes considered the result of spontaneous space arrangements. The recent literature, however, shows that urban vitality is not an intangible quality; it can be correlated to different place quality aspects, such as urban morphology, and measured through existing analytical methods. The aim of this paper is to systematize such indicators and use them to develop algorithms that can be subsequently incorporated into a computational tool for the assessment of knowledge territories during the early design stages, to support their spatial planning and development. The Paris-Saclay Urban Campus is used as a case study to understand and assess these vitality and place quality indicators in an existing benchmark. The results can contribute to the serendipity and the success of new or redeveloped knowledge and innovation areas. Full article

Culture-led urban regeneration represents a potent strategy for revitalizing post-industrial cities but necessitates navigating complex property rights fragmentation and competing stakeholder interests. This research interrogates how different institutional arrangements mediate this process, balancing economic development with cultural preservation and social sustainability. Through a comparative case study of two seminal projects in Xi’an, China—the Yisu Opera Society and the Old Food Market—this paper examines the divergent outcomes of two property rights reconfiguration strategies: land assembly and rights subdivision. Findings reveal a fundamental trade-off: while the land assembly model facilitates efficient, large-scale redevelopment and economic revitalization, it often precipitates gentrification and the erosion of socio-cultural fabric. Conversely, the rights subdivision approach, though incurring higher ongoing transaction costs, fosters more equitable and embedded regeneration by preserving community networks and authentic character. Grounded in Property Rights and Transaction Cost theories, this study con-structs an analytical framework to evaluate how governance structures, stakeholder dynamics, and contextual factors shape project outcomes. The research concludes that there is no universal solution; the optimal pathway depends on the specific heritage context and social embeddedness of a site. It contributes to urban scholarship by highlighting the critical role of flexible, hybrid governance models in managing urban complexity and offers practical policy insights for designing regeneration frameworks that can more equitably distribute the benefits of urban development.

The reuse of buildings of documentary value, as an expression of authorship and of a research trajectory within the debate on contemporary architectural design, represents a sustainable retrofitting approach, as it enables the extension of the life cycle of buildings as a resource. The adaptive reuse of buildings entails several cultural and technical challenges for a balance between conservation and transformation. This topic lies in the Italian debate on the technological, energy and housing needs inadequacy of the housing stock. Within this scenario, the PINQuA—Programma Innovativo Nazionale per la Qualità dell’Abitare (Innovative National Programme for Housing Quality) constitutes an innovative factor in the process of upgrading socially, physically, and functionally degraded housing contexts. The paper investigates the sustainable redevelopment of architects Franco Purini and Laura Thermes’ residential building block in the Marianella neighbourhood in Northern Naples. The methodology is based on the identification of the conditions of authorship, the relationship with the values of the pre-existing elements of the urban environment, and the expression of 1980s architecture. The results of the design proposal are measured by indicators of environmental and energy performance. The design proposal develops a retrofitting approach for contemporary housing by maintaining the residential function and reusing public and collective spaces adapted to the new climate regime and social needs.

As Chinese cities move toward stock-based development, the redevelopment of inefficient industrial land has become essential for urban spatial restructuring and sustainable transformation. Building on Lefebvre’s triadic theory of spatial production, this study establishes a comprehensive analytical framework consisting of spatial practice, representations of space, and representational spaces, aiming to elucidate the mechanisms underlying spatial reconfiguration. Through a multi-case inductive approach, twelve representative cases from Zhejiang Province are systematically analyzed to reveal the fundamental logic driving spatial reconstruction within the context of inefficient land redevelopment. The results reveal the following: (1) In the process of inefficient land redevelopment, spatial practice involves land reuse and functional integration, representations of space reflect institutional planning, and representational spaces shape meaning through cultural identity and user experience. These dimensions interact dynamically to drive the transformation of both the form and meaning of inefficient land. (2) The redevelopment of inefficient land in Zhejiang can be classified into two primary models: increment-driven and qualitative transformation, which are further divided into seven subtypes. The increment-driven model includes enterprise-initiated renewal, integrated upgrading, platform empowerment, and comprehensive remediation; the qualitative transformation model comprises mine remediation, cultural empowerment, and use conversion. (3) Significant differences exist between these models: the increment-driven model emphasizes land expansion and floor area ratio improvement, while the qualitative transformation model enhances land value through mine restoration, cultural embedding, and functional transformation. This study extends the application of spatial production theory within the Chinese context and offers theoretical support and policy insights for the planning and governance of inefficient industrial land redevelopment.

This study explores a submerged architectural strategy for data center deployment in coal mining subsidence water bodies, aiming to simultaneously address the underutilization of post-mining landscapes, the high-carbon operation of data centers, and the implementation challenges of China’s dual carbon goals. The proposed structure integrates wall-mounted plate heat exchangers into the façades of underwater data halls, using the natural convection of surrounding water as a low-grade heat sink to replace conventional cooling towers and achieve passive, low-carbon cooling. A thermal exchange model was developed based on heat transfer principles and validated by comparing outputs from TRNSYS simulations and MATLAB-based parameterized calculations, showing a deviation of less than 3% under all test conditions. The model was then used to estimate energy consumption, PUE, and carbon emissions under typical IT load scenarios. Results indicate a 42.5–64.3% reduction in cooling energy use and a 37.7–75.1% reduction in carbon emissions compared to conventional solutions, while a PUE range of 1.06–1.15 is maintained. The system also offers strong spatial adaptability and scalability, presenting a sustainable solution for redeveloping subsidence zones that supports ecological restoration and digital transformation in resource-depleted urban regions.

Urban centers shaped by industrial histories often exhibit complex patterns of land cover change that are not well-captured by standard classification techniques. This study investigates post-industrial urban change in Ponca City, Oklahoma, using remote sensing, unsupervised machine learning, and socioeconomic contextualization. Using a Jupyter Notebook version 7.0.8 environment for Python libraries, Landsat imagery from 1990 to 2020 was analyzed to detect shifts in land cover patterns across a relatively small, heterogeneous landscape. Principal component analysis (PCA) was applied to reduce dimensionality and enhance pixel distinction across multiband reflectance data. Socioeconomic data and historical context were incorporated to interpret changes in land use alongside patterns of industrial reduction and urban redevelopment. Results revealed changes in five distinct land cover classes of urban, vegetative, and industrial land uses, with observable trends aligning with key periods of economic and infrastructural transition. The trends also aligned with socioeconomic changes of the city, with a larger reduction in industrial and commercial land cover than in residential and vegetation cover types. These findings demonstrate the utility of machine learning classification in small-scale, heterogeneous environments and provide a replicable methodological framework for smaller city municipalities to monitor urban change.

Throughout history, communities have struggled to build homes in places actively hostile to their presence, a challenge long faced by African descendants in the American diaspora. In cities across the U.S., including Washington, D.C., efforts have often been made to erase Black cultural identity. D.C., once a hub of Black culture, saw its urban fabric devastated during the 1968 riots following Dr. Martin Luther King Jr.’s assassination. Since then, redevelopment has been slow and, more recently, marked by gentrification, which has further displaced Black communities. Amid this context, Black architects such as Michael Marshall, FAIA, and Sean Pichon, AIA, have emerged as visionary leaders. Their work exemplifies Value-Inclusive Design and aligns with Roberto Verganti’s Design-Driven Innovation by embedding cultural relevance and community needs into development projects. These architects propose an intentional approach that centers Black identity and brings culturally meaningful businesses into urban redevelopment, shifting the paradigm of design practice in D.C. This collective case study (methodology) argues that their work represents a distinct architectural style, Black Modernism, characterized by cultural preservation, community engagement, and spatial justice. This research examines two central questions: Where does Black Modernism begin, and where does it end? How does it fit within and expand beyond the broader American Modernist architectural movement? It explores the consequences of the destruction of Black communities, the lived experiences of Black architects, and how those experiences are reflected in their designs. Additionally, the research suggests that the work of Black architects aligns with heutagogical pedagogy, which views community stakeholders not just as beneficiaries, but as educators and knowledge-holders in architectural preservation. Findings reveal that Black Modernism, therefore, is not only a design style but a method of reclaiming identity, telling untold histories, and building more inclusive cities. Full article

In the stage of high-quality development, the functional coordination between transportation systems and territorial space is a key issue for improving urban spatial efficiency. This paper breaks through the traditional volume-to-capacity ratio analysis paradigm and innovatively integrates the “production-living-ecological space” theory. By introducing an improved accessibility evaluation model and developing a coordination measurement algorithm, a three-dimensional evaluation mechanism covering development potential assessment, service efficiency diagnosis, and resource allocation optimization is established. Empirical research indicates that the improved accessibility indicators can precisely identify the transportation location value of regional functional cores, while the composite coordination indicators can deconstruct the spatiotemporal matching characteristics of “transportation facilities—spatial functions,” providing a dual decision-making basis for the redevelopment of existing space. This measurement system innovatively realizes the integration of planning transmission mechanisms with multi-scale application scenarios, guiding both overall spatial planning and urban renewal area re-optimization. The methodology, applied to the urban villages of Guangzhou, can significantly increase land utilization intensity and value. The research results offer a technical tool for cross-scale collaboration in land space planning reforms and provide theoretical innovations and practical guidance for the value reconstruction of existing spaces under the context of new urbanization.

Land requirements and impacts from future development are a significant concern throughout the world. In Florida (USA), the state’s population increased from 18.8 M to 21.5 M between 2010 and 2020, and is projected to reach 26.6 M by 2040. To accommodate these new residents, 801 km² of wetlands were converted to developed uses between 1996 and 2016. These conversions present a significant threat to Florida’s unique ecosystems and highlight the need to prioritize conservation and water resource protection, both for the natural and human services that wetland and upland landscapes provide. To better understand the relationship between future development and water resources, we used future development and event mean concentration (EMC) models for Escambia and Santa Rosa counties in Florida (USA) to assess impacts from development patterns on water quality/runoff and water resource protection priorities. This study found that if future development densities increased by 30%, reductions of 7713 acres for developed land, 17,768 acre feet of stormwater volume, ~88k lb/yr total nitrogen, and ~15k lb/yr total phosphorus could be achieved. It also found that urban infill, redevelopment, and stormwater management are essential and complementary tools to broader growth management strategies for reducing sprawl while also addressing urban stormwater impacts.

This study investigates the challenges and opportunities of balancing cultural preservation, tourism investment, and community resilience in historic Syrian cities during the post-war recovery period. The Syrian conflict has imposed considerable harm upon the nation’s cultural heritage, encompassing UNESCO World Heritage sites, thereby interrupting not only the urban infrastructure but also local economies and social networks. Utilizing a comprehensive methodology that includes a literature review, stakeholder interviews, and local surveys, this research investigates the potential for aligning cultural preservation with tourism investment to promote sustainable economic revitalization while simultaneously enhancing social cohesion and community resilience. The results underscore the significance of inclusive governance, participatory planning, and capacity enhancement to guarantee that post-conflict urban redevelopment fosters enduring environmental, social, and cultural sustainability. By framing the Syrian case within the broader context of global urban sustainability and resilience discourse, the study offers valuable insights for policymakers, urban planners, and heritage managers working in post-conflict or post-disaster environments worldwide. In the end, the study highlights that the revitalization of historic cities transcends being a simple technical or economic endeavor; it is a complex process of re-establishing identity, strengthening communities, and fostering sustainable, resilient urban futures.

Urban transportation systems face increasing pressure to reduce car dependency and greenhouse gas emissions while supporting sustainable growth. This study addresses the lack of integrated modeling approaches that capture both spatial and temporal dynamics in transport planning. It develops a novel framework combining System Dynamics (SD) and Geographic Information Systems (GIS) to assess the sustainability of Transit-Oriented Development (TOD) strategies and parking policies in two brownfield redevelopment sites in Montreal. The framework embeds spatial metrics, such as proximity to transit, parking availability, and active transportation infrastructure into dynamic feedback loops. Using scenario analysis, the study compares a baseline reflecting current norms with an intervention scenario emphasizing higher density near transit, reduced parking ratios, and improved walkability and bike infrastructure. The results suggest that aligning TOD principles with targeted parking limits and investments in active mobility can substantially reduce car ownership and emissions. While primarily conceptual, the model provides a foundation for location-sensitive, feedback-driven planning tools that support sustainable urban mobility. Full article

The rapid urbanization of contemporary cities represents one of the most complex challenges of the 21st century, with profound implications for the environmental, social, and economic sustainability of territories. In this context, urban regeneration emerges as a strategic approach to territorial transformation. The complexity of urban dynamics requires the adoption of innovative paradigms and systemic approaches capable of guiding decision-making processes toward eco-sustainable and resilient solutions. This research develops advanced decision support tools for urban regeneration, using the city of Potenza (Italy) as a case study. The main objective is to identify key indicators to evaluate the effectiveness of urban regeneration interventions in advance (ex-ante). The methodology develops a composite economic-financial risk index capable of providing an accurate picture of existing conditions while adapting to the territorial specificities of the analyzed area. This index, which uses the Analytic Hierarchy Process (AHP) technique to integrate elementary economic-financial indicators in order to assess the sustainability level of urban redevelopment projects, is able to synthesize complex economic variables into a single parameter of immediate comprehension, strategically guiding investments toward a sustainable urban development model. The analysis of results highlights a peculiar territorial configuration: semi-central areas present the greatest criticalities, while there is a progressive decrease in risk both toward the central core and toward peripheral and extra-urban areas. The study represents a significant methodological contribution to future urban regeneration initiatives at the local level, promoting an integrated vision of sustainable urban development for the benefit of current and future generations.
