Cultural heritage can strengthen urban resilience when mobilized as educational infrastructure that builds stewardship, place attachment, and civic agency. This study examines whether the Art Nouveau Path, an outdoor mobile augmented reality heritage game in Aveiro, Portugal, can function as a curriculum-aligned pathway for sustainability competences and resilience-relevant meaning-making in formal education. A curriculum translation matrix mapped eight points of interest and 36 tasks to Portuguese curriculum anchors, Education for Sustainability themes, GreenComp sustainability competences, and the Sustainable Development Goals, framing the matrix as an adoption-oriented design artefact. Empirical evidence comprised accompanying teachers’ in-field observations (T2-OBS; N = 24 across 18 sessions) and students’ post-activity survey data (S2-POST; N = 439), with open-ended reflections coded through a directed resilience-mechanism codebook (Krippendorff’s alpha = 0.91). Teachers reported high perceived value and feasibility and frequently noted enacted stewardship and placed responsibility during sessions. Students’ reflections most often linked resilience to sustainable conservation under pressure and to nature-city interconnections, whereas hazard-memory mechanisms appeared less often. Adoption-related evidence is limited to teacher feasibility reports and institutional legibility from curriculum translation, rather than confirmed institutional uptake indicators. Scaling is likely to require explicit supports for differentiation, assessment scaffolds, and routine delivery in public spaces. Full article

Operable windows are critical for indoor environmental quality (IEQ) and occupant agency, yet their usability is increasingly compromised by conflicts between regulatory compliance and building performance. This study investigates the gap between geometrically compliant provisions and effectively operable windows through a comparative policy analysis of mandatory codes (Level 1), green rating systems (Level 2), and regenerative frameworks (Level 3). The findings identify a structural discrepancy termed the Geometric Trap: while minimum opening areas are legally required, mechanical ventilation often substitutes for natural access. In the United States, Japan, and Republic of Korea, explicit waivers permit full substitution, while in the United Kingdom, conditional constraints such as environmental noise limit practical operability. Germany, by contrast, maintains operable windows as an independent mandate, restricting substitution to defined environmental conditions. Although emerging green rating systems increasingly recognize resilience and adaptive comfort, operability remains optional. Regenerative standards, however, treat it as a prerequisite for occupant health. This study proposes a shift from static geometric compliance toward an Effective Opening Area framework that evaluates actual accessibility and usability, advancing a performance-based and occupant-centered regulatory perspective.

Earthen materials are attractive sustainable building solutions due to their low embodied energy and ecological benefits. However, their inherent weaknesses, such as low strength and poor durability, severely restrict modern engineering applications. Traditional physical or chemical modification methods struggle to balance significant improvement in mechanical performance with the preservation of their core sustainable attributes. To overcome this long-standing challenge, this study proposes a paradigm-shifting solution: a prefabricated monolithic lattice–earth composite wall structure. This system abandons the single-material-centered modification approach. Instead, through macroscopic system-level composite design, reinforced concrete lattices and earthen blocks are prefabricated into integral wall panels in a factory. These panels then work collaboratively with the peripheral frame through reliable integral connections. Via quasi-static tests and theoretical analysis on four scaled wall specimens with different design parameters, this study systematically reveals the working mechanism and performance regulation principles of this composite system. The core findings indicate: (1) The system achieves multiple seismic defense lines and a controllable energy dissipation path through a sequential damage mechanism: “earthen material cracking and friction → lattice yielding and energy dissipation → final defense by the frame.” (2) The ratio of the equivalent lateral stiffness of the prefabricated wall panel to the stiffness of the outer frame is a key dimensionless design parameter controlling the failure mode (ductile shear or brittle bending), and the lattice configuration is an effective means to adjust this parameter. (3) Based on tests and an equivalent stiffness model, quantitative design guidelines are proposed, focusing on optimizing lattice density (recommended: 3–4 lattice columns), limiting the aspect ratio (preferably ≤1.5), and ensuring “strong connections.” This study demonstrates that the system, without sacrificing the intrinsic sustainable advantages of earthen materials, successfully endows them with high performance, meeting modern seismic code requirements and potential for prefabricated construction through system integration innovation. It provides a new path with theoretical foundation and practical feasibility to resolve the core contradiction in the modernization of traditional earthen buildings—the incompatibility between ecological attributes and engineering performance. This lays an important foundation for developing next-generation high-performance green building structural systems. Full article

This study examines how technological innovation and sustainability jointly reshape contemporary public administration by integrating digital transformation with public value creation. Using a mixed-method approach, we compile a Scopus-based bibliographic dataset and conduct descriptive and network analyses on 199 articles to map publication trends, methodological patterns, and core keyword clusters. We then perform an in-depth qualitative content analysis of 83 papers, coding public sector domains, actors, technological innovations, and sustainability dimensions. Findings highlight a shift from early e-government, centered on administrative efficiency, toward a paradigm of “sustainable digital governance”, where AI, IoT, blockchain and data analytics drive the twin digital–green transition. Five conceptual clusters and several application domains show that public value increasingly emerges within collaborative ecosystems involving administrations, firms, universities, citizens and digital platforms. The study offers an integrated overview of this evolving field and clarifies technology’s role as an enabling factor in sustainable governance. Building on the review results, we propose the Sustainable Public Innovation Ecosystem (SPIE) framework, which links systemic enablers (technological and sustainability innovation) governance efficiency and sustainable public value through ecosystem dynamics and governance mechanisms. It also outlines a future research agenda on hybrid actors ethical and regulatory issues, and approaches to measuring sustainable public value, providing guidance for scholars and policymakers designing digitally enabled and sustainability-oriented public reforms.

This article examines the role of coworking and flexible workspaces in promoting sustainable spatial development in the non-metropolitan areas of Bulgaria. A mixed-method approach was applied, combining inventory enumeration, spatial classification, SDG-based sustainability assessment, and qualitative coding (open, axial, selective). A total of 74 coworking and flexible workspaces were identified across the six national planning regions, evaluated according to six analytical criteria (accessibility, seasonality, specialization, municipal administrative district, urban planning zone, building function) and assessed against five SDG-aligned dimensions (SDG 8, 9, 11, 12, 13). The results reveal uneven territorial distribution, strong concentration in major cities outside the capital, and emerging sustainable models in peripheral areas. Comparative SDG scoring and typological interpretation demonstrate three recurring models—Sustainable Reuse, Nature-Oriented, and Innovative/Experimental—each associated with distinct spatial and environmental characteristics. A metropolitan benchmarking exercise further contextualizes the strongest sustainability profiles. Based on these findings, a conceptual sustainable coworking model is developed for a nationally significant spa and climatic resort, illustrating how coworking can address regional disparities, support green transition policies, and reinforce territorial cohesion. The article concludes by outlining research directions related to digitalization, circular construction, environmental performance indicators, and feasibility assessments for non-metropolitan coworking development.

This article examines the discursive dynamics of depoliticization in the European Union’s ecological transition, focusing on the Just Transition Mechanism (JTM), a key instrument of the European Green Deal. Building on critical scholarship, we start from the observation that EU governance often frames environmental challenges as neutral and technical, obscuring their political nature and narrowing the space for alternatives. To assess how such processes unfold, we conducted a thematic analysis of plenary debates in the European Parliament and official Commission statements concerning the JTM. Using a coding framework centered on conflict, authority, agency, and alternative futures, the analysis shows that parliamentary discourse largely reduces contestation to issues of financial allocation, technical feasibility, and procedural compliance. EU institutions emerge as the main agents and sources of authority, depicted as leading and safeguarding the transition, while regions and local actors appear in adaptive and dependent roles. Although references to social justice and generational responsibility occasionally surface, transformative visions challenging growth-oriented or technocratic paradigms remain absent. Nonetheless, traces of politicization suggest latent openings for contestation, highlighting the need for future research on whether bottom-up actors (unions, municipalities, grassroots movements) can re-politicize the field of transition.

Optimizing the life cycle of buildings within the green transition must also encompass foundations, which significantly influence material consumption and the embodied carbon of structures. Accurate settlement prediction is a cornerstone of sustainable design; however, engineering practice often relies on simplifications, such as assuming a constant soil deformation modulus, that lead to oversizing of foundation elements. This paper examines two types of shallow foundations, an isolated footing and a raft, founded in sandy subsoil, and compares calculation outcomes obtained using five approaches: a code-based method, parameters derived from oedometer tests, parameters from triaxial tests, and two Janbu variants that account for stiffness increasing with depth. The results reveal substantial variability in predicted settlements, ranging from underestimation with the code-based approach to overestimation with the oedometer method. The most realistic predictions were obtained using triaxial parameters and the nonlinear model, which better capture the actual deformation mechanisms of the subsoil. Although the primary aim of this study is to improve the technical accuracy of settlement prediction, these findings also demonstrate that precise geotechnical modeling naturally supports resource efficiency and contributes to sustainable construction as a secondary, yet measurable, outcome of rational design.

Form-based design codes have emerged as a planning tool aimed at shaping the physical form of neighborhoods to reinforce local character and enhance sense of place (SoP). However, their effectiveness in delivering these outcomes remains underexplored. This study investigates the extent to which Buffalo’s Green Code—a form-based zoning ordinance—enhances SoP in residential environments, using Elmwood Village as a case study. A multi-scalar analytical framework assesses SoP at the building, street, and neighborhood levels. Empirical data were gathered through an online survey, while the neighborhood was systematically mapped into street segment blocks categorized by Green Code zoning. The study consolidates six Green Code classifications into three overarching categories: mixed-use, residential, and single-family. SoP satisfaction is analyzed through a two-step process: first, comparative assessments are conducted across the three zoning groups; second, k-means clustering is applied to spatially map satisfaction levels and evaluate SoP at different scales. Findings indicate that mixed-use areas are most closely associated with place identity, while residential and single-family zones (as defined by the Buffalo Green Code) yield higher satisfaction overall—though satisfaction varies significantly across spatial scales. These results suggest that while form-based codes can strengthen SoP, their impact is uneven, and more scale-sensitive zoning strategies may be needed to optimize their effectiveness in diverse urban contexts. This research overall offers an empirically grounded, multi-scalar assessment of zoning impacts on lived experience—addressing a notable gap in the planning literature regarding how form-based codes perform in established, rather than newly developed, neighborhoods.

Considering the climate crisis, global environmental awareness, and the pursuit of sustainable architecture, various methodologies and global standards have been developed to assess and reduce the environmental impact of construction projects. Green Building Codes (GBCs) and rating systems have been implemented worldwide to support green building practices based on the use of simulation models to evaluate energy consumption, such as the ENERGYui and others to rate buildings based on their simulated energy performance. Israel has also established green building standards, such as SI 5281, which provide practical tools for architects to promote the use of green building methods. However, several studies have cast doubt on the actual measured performance of certified buildings. This study evaluates the effectiveness of the Israeli green building certification process (SI 5281/SI 5282) through a comparison between simulation-based ratings with measured post-occupancy electricity consumption. Through four case studies, the research identifies discrepancies, explores their causes, and proposes refinements to certification assumptions and evaluation methods. The research is intended to enhance the effectiveness of assessment tools in architectural design and contribute to more precise and sustainable green building practices. This study identifies significant gaps between simulated and actual energy consumption in Israeli green buildings, highlighting that, within this framework, educational buildings tend to exceed predicted usage, while residential buildings often consume less, thereby exposing limitations in current simulation assumptions and standard evaluation criteria.

Urban green infrastructure (UGI) projects rely on collaboration and involve a diverse team of professionals, including constructors, designers, green builders, and maintenance staff. This socially oriented case study focuses on the relational dynamics among UGI professionals, their roles in landscape construction processes, and how these relationships can influence the project’s success and its capacity to implement carbon-smart solutions. “Carbon-smart solutions” refers here to practices aimed at maximising carbon sequestration and storage while minimising carbon emissions. Data for this study were collected through semi-structured in-depth interviews and analysed using deductive qualitative analysis. A coding framework, investigator triangulation, and a representative sample of various professionals were employed to confirm the data’s validity. This study identified several relational factors that either challenge or drive the project’s success and carbon smartness. At the interpersonal level, the determinant drivers and challengers in UGI professionals’ relations were linked to the definition of working roles, power dynamics, the building of mutual trust through open communication, and the possession of the necessary sustainability skills. At the institutional level, relations concerning the shared principles and rationales of the project, as well as the project design process and diverse working cultures, presented both constraints and advances in project success and carbon-smart solutions.

The construction sector plays a pivotal role in sustainability efforts, driving the need for innovative solutions like Building Information Modeling (BIM) to optimize green building design and performance. This study examines the diffusion of BIM functionalities that support sustainability, particularly in energy efficiency, water management, material selection, indoor environmental quality, and green building certification. Using the innovation diffusion theory, the research employs three mathematical models—internal, external, and mixed—to analyze the adoption patterns of BIM for green building applications. Empirical findings reveal that external factors, such as government regulations, financial incentives, and industry trends, significantly influence the diffusion of BIM functions related to environmental performance. The mixed diffusion model demonstrates the highest explanatory power, indicating that both external and internal drivers play a role, particularly in material selection and lifecycle assessment. This study highlights the growing integration of BIM in sustainable construction, reinforcing the need for regulatory support to accelerate adoption. These findings offer valuable insights for researchers, policymakers, and industry professionals, demonstrating how BIM can drive greener practices in the built environment. Policymakers should focus on developing policies and offering incentives such as feed-in tariffs, investment tax credits, and integrating Green BIM requirements into building codes to encourage sustainable construction practices. Also, curricula should be updated to include real-world projects and experiential learning to improve the adoption and efficiency of Green BIM practices. Future research should explore enhanced digital frameworks to further improve BIM’s impact on sustainability and lifecycle optimization. Full article

The behavior factor, which represents the force reduction that a structure would experience if its response was completely elastic compared with the seismic forces used for design, is defined in seismic design codes for common construction techniques and materials. A specific assessment is needed when novel construction materials are adopted. The lack of accurate structural performance estimations limits the use of green construction materials because building codes only allow the use of minimum values for the behavior factor. This research aims to verify the reliability of the proposed capacity-demand-based (CDB) method for the estimation of the force reduction factor and behavior factor, by comparison with other procedures such as demand-based, capacity-based and formula-based approaches. The main characteristic of the proposed approach is that the ductility-FRF curve is obtained numerically for the building natural period, instead of imposing an analytical FRF-ductility-period relationship. The advantage of the CDB-method is its efficiency from a computational point of view without restrictions concerning the construction material and structural typology. The results are compared in the case where dynamic analyses are performed for a three-dimensional (3D) building model (considered as a reference) and for an equivalent single-degree-of-freedom system which reduces the computation time. The CDB-method yields safe results compared with the N2 method, and it is consistent with a capacity-based approach applied to the 3D building model. Full article

Urban parks provide areas for human wellbeing and green space benefits in densely populated landscapes but cannot accomplish all their goals in isolation. They require assistance from collaborations to address challenges. The need for these collaborations is often codified in planning documents. We assisted Rock Creek Park (National Park Service, Washington, D.C.) in their considerations of where to place “partnerships” in their strategic plan by sourcing and summarizing goal topics, hierarchies, and relationships from peer park plans. Using textual coding and network analysis approaches, we examined strategic planning documents from park system entities across the 20 largest urban areas in the United States. We found that, topically, Rock Creek Park’s five initial strategic planning goal topics—safety, access, stewardship, community engagement, and employee engagement—were common and both inward and outward-facing goals. Hierarchically, “partnerships” was routinely considered as a primary goal (a stand-alone topic) and as an integrated secondary goal (supportive within other topics). Additionally, we identified “community building” as an important, outward facing “assistance” goal, differentiated from “partnerships” in audience and encompassing how a park shows up for the urban community and demonstrates its value to the region. We discuss these findings toward urban park planning processes. Full article

The European building stock is aging and needs renovation. Holistic renovation approaches, including Vertical Forest (VF) systems, are emerging as sustainable alternatives to demolition and reconstruction. This paper reviews and defines missing reliable damage and hazard intensity measures for the holistic renovation of existing reinforced concrete (RC) buildings with VF systems. Based on an extensive literature review and preliminary studies, including empirical multiparametric system evaluation assessments, Monte Carlo simulations, and System-Theoretic Process Analysis (STPA), combined structural, non-structural, vegetation, and human comfort components are examined. Key damage indicators are identified, including interstory drift ratio, residual deformation, concrete and reinforcement strains/stresses, and energy dissipation, and their applicability to VF-integrated structures are evaluated. Green modifications are found to have higher risk profiles than traditional RC buildings (mean scores from Monte Carlo method: 9.72/15–11.41/15 vs. 9.47/15), with moisture management and structural integrity as critical concerns. The paper advances the understanding of hazard intensity measures for seismic, wind, and rainfall impacts. The importance of AI-driven vegetation monitoring systems with 80–99% detection accuracy is highlighted. It is concluded that successful VF renovation requires specialized design codes, integrated monitoring systems, standardized maintenance protocols, and enhanced control systems to ensure structural stability, environmental efficiency, and occupant safety.

In this study, 45 alternative green materials for building walls were experimentally produced, utilizing renewable (epoxidized sesame oil), natural (clay), and waste (Seyitömer fly ash) resources. These materials were evaluated based on key technical properties such as mass, tensile-compressive strength, and thermal conductivity, all of which are essential for construction and insulation applications. Subsequently, theoretical modeling was conducted for the material coded SE45, which demonstrated the lowest thermal conductivity. Through mathematical calculations, the theoretical thermal conductivity value was determined with a deviation of +5.88%. Furthermore, 48 alternative scenarios were designed for three different building envelope types (internally insulated, externally insulated, and sandwich), using commonly used building insulation materials alongside the sesame oil-based green material with the lowest thermal conductivity (SE45). Energy performance evaluations were conducted by analyzing temperature distributions along the walls of all designed scenarios using ANSYS simulations under the climatic conditions of Ankara, Turkey.
