This study examines the urban planning strategies and implementation characteristics of spatial structures in the Rosenstein Development District, a project based on the Stuttgart 21 initiative and the Green-U concept, as a case of carbon-neutral urban restructuring. The focus is on strategies grounded in a public transportation system that prioritizes walking and cycling. The study analyzes the planning and implementation process in three stages. First, it theoretically reviews the urban restructuring process and planning strategies, and analyzes key planning documents. Second, it investigates land use designations and spatial structure based on strategies of mixed-use development, community hubs, and pedestrian–green linkages. Third, it identifies spatial typologies such as a carbon-neutral mixed-use district, an open-campus residential district, and an innovation-integrated industrial zone. In conclusion, this case presents a representative model of carbon-neutral urban spatial restructuring through transit-oriented redevelopment, offering valuable foundational insights for the application of carbon-neutral planning in future station-area regeneration projects in Korea.

The purpose of this study is to develop a housing demand estimation model incorporating the concept of the de facto population, with a focus on Maengdong-myeon in Eumseong-gun. To achieve this, housing demand was estimated using three models—the traditional model, the district-based model, and the mobility-based model and the results were compared to identify the most suitable model for small and medium-sized local cities. The traditional model, based on the unit-rate method applied to industrial complexes, estimated a total demand of 7,302 housing units. However, this approach was found to be limited in its applicability to local urban contexts. The district-based model, which incorporates factors such as population trends, housing supply rates, industrial and regional development, land price fluctuations, and population mobility, estimated a demand of 3,831 units, reflecting the current conditions of local cities more accurately. Finally, the mobility-based model integrating the de facto population concept estimated demand at 4,292 units and was evaluated as the most appropriate model for areas experiencing population outflow and residential instability. The findings suggest that for local cities facing demographic decline, housing demand estimation should move beyond traditional approaches and instead incorporate the de facto population framework for greater accuracy and relevance.

With the global implementation of carbon neutrality policies, photovoltaic (PV) power generation is gaining attention as a key energy source. As the adoption of BIPV (Building-Integrated Photovoltaics) and BAPV (Building-Applied Photovoltaics) systems increases, installations of PV modules in various orientations are also becoming more common. Accordingly, research on the accuracy of PV output prediction tools such as PVsyst is needed, but studies in this area remain limited. In this study, PV output was measured at two tilt angles (30° and 90°) and five orientations (east, west, south, north, and horizontal), and the error rates between the measured values and PVsyst predictions were analyzed. The average error rates across eight selected days were: for 90° tilt — 5.3% (horizontal), 15.5% (east), 7.1% (west), 7.2% (south), and 16.5% (north); and for 30° tilt — 5.3% (horizontal), 5.5% (east), 3.5% (west), 4.9% (south), and 16.5% (north). This study is expected to contribute to evaluating the prediction accuracy of PVsyst under diverse installation conditions and enhancing the reliability of PV output analysis.

This study investigates how negative modern heritage has been excluded and erased in Korea’s modern and contemporary history, focusing on the formation and demolition process of the Samgwang Cheongju Brewery. To that end, it analyzes historical records and spatial data related to the brewery, along with media coverage and interviews with stakeholders during the demolition process, to reflect on the value of this now-lost modern heritage. The findings suggest that the case of the Samgwang Cheongju Brewery became a turning point for recognizing the significance and necessity of preserving negative modern heritage within the local community. They also reveal the emergence of an institutional foundation for preserving modern heritage as a future-oriented legacy. Over its 100-year history, the brewery has functioned as a key industrial facility in the region, embodying a complex form of modern heritage that integrated Japanese-style brewing techniques and combined production and residential spaces, urban architecture, local lifestyle culture, and landscape. The Samgwang Cheongju Brewery built in Japanese colonial era was not recognized as a preservation value by both the public and private sectors because of its image as a declining industry and an outdated space. However, its demolition sparked a public discourse around the meaning and treatment of negative modern heritage. Through this study, it is expected that preemptive preservation efforts for modern heritage left behind and discussions on utilization will be expanded in various aspects.

Design certification in architecture has traditionally relied on manual 2D drawing reviews, limiting consistency and efficiency while failing to reflect qualitative elements such as Crime Prevention Through Environmental Design (CPTED). As digital transformation accelerates, the need for automated evaluation using Building Information Modeling (BIM) is increasing. This study aims to improve CPTED design certification by quantifying evaluation criteria and applying a BIM-based automated methodology. The domestic CPTED certification structure was analyzed, and evaluation items were classified into quantitative and qualitative types. A methodology was developed to extract and assess BIM object data—specifically focusing on attributes like property, location, and geometry. The study explored how CPTED evaluation criteria could be mapped to BIM attributes for automated assessments. Results show the potential of BIM in enhancing CPTED certification through digital evaluation methods. This study contributes foundational insights for building practical, automated evaluation systems applicable to commercial, residential, and other facility types.

This study conducted a comparative analysis of urban regeneration projects in Busan Dong-gu and London Docklands to explore strategies for improving the effectiveness of sustainable urban regeneration. Both regions experienced urban decline due to the deterioration of port functions but pursued different approaches to regeneration projects. The research methodology employed comparative case analysis through literature review and case studies, focusing on project background and overview, implementation systems and governance, major project contents, and achievements and limitations. The analysis revealed that Busan Dong-gu achieved success in preserving regional identity and expanding resident participation through a public-led gradual improvement approach, but showed limitations in securing economic sustainability. In contrast, London Docklands achieved overwhelming economic success through a market-centered large-scale development approach, creating 85,000 jobs and attracting 2,700 companies, but faced issues of gentrification and social exclusion. This study confirmed that the approach and implementation system of urban regeneration have a decisive impact on project outcomes and sustainability. Based on these findings, five policy implications were derived: the necessity of region-specific approaches, strengthening the professionalism of implementation systems, activating private participation, preventing gentrification, and establishing long-term performance evaluation systems.

The present study aimed to identify the risk factors in the operation of small- and medium-sized construction project financing (PF) development projects, and further to evaluate their relative importance. A careful literature review along with Delphi study leaded to the design of four major criteria of risk factors including ‘financial risk’, ‘business feasibility risk’, ‘construction and operational risk’, and ‘stakeholder risk’. In addition, a total of twelve indexes were identified. A survey was administered to 100 experts to collect pairwise comparison data. The collected data were analyzed using the Analytic Hierarchy Process (AHP). Results indicate that ‘business feasibility risk’ emerged as the most important criteria among four risk criterion. Furthermore, ‘funding risk’, ‘failure in location/commercial area analysis’, ‘contractor insolvency and project suspension’, and ‘conflict with local community/public agencies’ were found to be the most important index within each respective risk criteria. Our findings of the current work also show that ‘failure in location/commercial area analysis’, ‘increase in project costs’, ‘funding risk’, and ‘demand forecasting error’ were ranked as the important index for careful consideration in practice.
