As a response, we propose a framework integrates street view images (SVIs) with a large vision-language model, termed CLIP, to accurately measure fine-grained urban poverty. Subsequently, multi-source data poverty index (MDPI) is calculated and used to assess the reliability of poverty perceptions. Finally, the nonlinear effects of street scenes on poverty perceptions are analyzed. This newly-proposed method not only demonstrates a consistent distribution with MDPI but also exhibits better spatial resolution and efficiency than existed ones. This study introduces a CLIP into urban studies, showing potentials for measuring urban poverty, particularly in emerging market countries where there is an abundance of Internet open data but limited statistical records.

Current approaches tend to polarize alternatives, focusing either on broad functional use or specific design options, which can limit decision effectiveness and quality. This study addresses these challenges by developing a participatory mixed-methods approach that integrates Cross-Impact Balance (CIB) analysis with creative scenario-building techniques, including generative AI and participatory workshops. This approach balances the extremes of current decision-making processes, offering a more comprehensive overview of desirable futures for decision-makers. The methodology was applied to create 15 “big picture” circular adaptive reuse scenarios, each incorporating circular building adaptability (CBA) strategies, and enriched with AI generated narratives and visualizations. These scenarios provide stakeholders with a nuanced understanding of potential future pathways, enhancing decision-making processes. This mixed-method approach demonstrates the potential of participatory CIB scenario development in advancing circularity, offering a valuable tool for navigating the complexities of adaptive reuse decision-making.</div></div>","PeriodicalId":48659,"journal":{"name":"Sustainable Cities and Society","volume":"122 ","pages":"Article 106259"},"PeriodicalIF":10.5,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143580388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, due to the variable nature of PV, its integration adds complexity to grid management, requiring careful consideration of the energy balance. This study addresses the challenges of energy transition and urban sustainability in densely populated cities through a case study of rooftop photovoltaic (PV) integration in the Grand Paris metropolis. Focusing on energy balance metrics such as self-consumption rate (SCR) and self-sufficiency rate (SSR), the research explores the benefits of distributed PV installations across residential and commercial sectors. Using hourly electricity consumption profiles and PV generation data, the analysis evaluates the impact of energy-sharing schemes within and across urban subregions (city center and semi-urban periphery) and between sectors. The results show that, over an extended scope, cross-sector energy sharing can improve SCR and SSR by up to 6.5% across sectors and 10% across geographical subregions. 3.19 TWh of regional residential consumption and 0.44 TWh of commercial consumption could be covered by PV, accounting for 22.4% of the total for both sectors. The periphery benefits significantly from increased SSR, linked to lower building density and higher PV capacity. Economically, rooftop PV reduces energy costs most in peripheral regions, with expanded energy-sharing perimeters enabling additional savings for central areas. These findings suggest that broader energy-sharing frameworks in metropolitan areas can optimize PV utilization, enhance grid stability, and contribute to resilient, sustainable urban energy systems.</div></div>","PeriodicalId":48659,"journal":{"name":"Sustainable Cities and Society","volume":"122 ","pages":"Article 106232"},"PeriodicalIF":10.5,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143563770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
