Architecture

The rapid evolution of the metaverse is driving the development of new digital design tools that integrate Computer-Aided Design (CAD) and Building Information Modeling (BIM) technologies. Core technologies such as Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR) are increasingly combined with BIM to enhance collaboration and innovation in design and construction workflows. However, current BIM–VR integration often remains limited to isolated tasks, lacking persistent, multi-user environments that support continuous project collaboration. This study proposes a BIM-based Virtual World (VW) framework that addresses these limitations by creating an immersive, real-time collaborative platform for the Architecture, Engineering, and Construction (AEC) industry. The system enables multi-user access to BIM data through avatars, supports direct interaction with 3D models and associated metadata, and maintains a persistent virtual environment that evolves alongside project development. Key functionalities include interactive design controls, real-time decision-making support, and integrated training capabilities. A prototype was developed using Unreal Engine and supporting technologies to validate the approach. The results demonstrate improved interdisciplinary collaboration, reduced information loss during design iteration, and enhanced stakeholder engagement. This research highlights the potential of BIM-based Virtual Worlds to transform AEC collaboration by fostering an open, scalable ecosystem that bridges immersive environments with data-driven design and construction processes.

The 4E Cognition paradigm offers a novel theoretical framework for understanding how acoustic environments influence cognitive processes in university learning spaces. This research integrates objective characterization of environmental parameters with comprehensive subjective evaluation of student experience to explore how aural conditions relate to cognitive processes and physiological stress responses in university learning environments. The study recruited 126 university students from the Engineering Faculty of “G. D’Annunzio” University, with final analysis including 66 valid responses from 28 participants in the acoustically treated classroom and 38 from the control condition. The results revealed modest associations between environmental conditions and cognitive performance measures, with small to moderate effect sizes (Cohen’s d ranging from 0.02 to 0.31). While acoustic treatment produced measurable improvements in speech intelligibility and acoustic quality ratings, differences in cognitive load and allostatic load indices were minimal between conditions. These findings provide preliminary empirical insights for applying the 4E Cognition framework to educational settings, suggesting that acoustic interventions may require extended exposure periods or more intensive treatments to produce substantial physiological and cognitive effects. This work contributes to the emerging field of cognitive architecture by introducing an innovative theoretical approach that reconceptualizes acoustic environments as potential cognitive extensions rather than mere background conditions. The findings offer initial evidence-based insights for integrating environmental considerations into educational facility design, while highlighting the need for longitudinal studies to fully understand how acoustic environments function as cognitive scaffolding in learning contexts.

This paper explores the complexities of measuring impact from placemaking in the context of public and community housing (sometimes known as social or subsidised housing) in Aotearoa New Zealand. Placemaking refers to a range of practices and interventions—including the provision or facilitation of access to community infrastructure—that seek to cultivate a positive sense of place through everyday experiences, spaces, relationships, and rituals. Drawing on interviews with four community housing providers (CHPs), analysis of their documentation, and tenant survey and interview data from two of those CHPs, this research examines providers’ change theories about placemaking in relation to tenants’ experiences of safety, belonging and connectedness, including access to local amenities, ease of getting around, and a sense of neighbourhood and community affiliation. Based on the importance of these variables to wellbeing outcomes, the study highlights the potential of placemaking to support tenant wellbeing, while also recognising that providers must navigate trade-offs and co-benefits, limited resources, and varying levels of tenant engagement. While placemaking can help to foster feelings of connection, belonging and safety, its impact depends on providers’ capacity to initiate and sustain such efforts amidst competing demands and constraints. The study offers indicative findings and recommendations for future research. Although the impacts of placemaking and community infrastructure provision are difficult to quantify, research findings are synthesised into a prototype framework to support housing providers in their decision-making and housing development processes. The framework, which should be adapted and evaluated in situ, potentially also informs other actors in the built environment—including architects, landscape architects, urban designers, planners, developers and government agencies. In Aotearoa New Zealand, where housing provision occurs within a colonial context, government agencies have obligations under Te Tiriti o Waitangi to actively protect Māori rights and to work in partnership with Māori in housing policy and delivery. This underscores the importance of placemaking practices and interventions that are culturally and contextually responsive. Full article

This study investigates the influence of rear setback geometry and façade design parameters on microclimatic conditions, indoor thermal comfort, and energy performance in multi-story residential buildings in hot arid climates, addressing the growing need for climate-responsive design in regions with extreme temperatures and high solar radiation. Despite increasing interest in sustainable strategies, the combined effects of urban geometry and building envelope design remain underexplored in these environments. A coupled simulation framework was developed, integrating ENVI-met for outdoor microclimate modeling with Design Builder and EnergyPlus for dynamic building performance analysis. A total of 270 simulation scenarios were examined, combining three rear setback aspect ratios (1.5, 1.87, and 2.25), three window-to-wall ratios (10%, 20%, and 30%), three glazing types (single-, double-, and triple-pane), and two wall insulation states, using customized weather files derived from microclimate simulations. Global sensitivity analysis using rank regression and multivariate adaptive regression splines identified the glazing type as the most influential parameter (sensitivity index ≈ 0.99), especially for upper floors. At the same time, higher aspect ratios reduced peak Physiological Equivalent Temperature (PET) by up to 5 °C and decreased upper-floor cooling loads by 37%, albeit with a 9.3% increase in ground-floor cooling demand. Larger window-to-wall ratios lowered lighting energy consumption by up to 35% but had minimal impact on cooling loads, whereas wall insulation reduced annual cooling demand by up to 29,441 kWh. The results emphasize that integrating urban morphology with optimized façade components, particularly high-performance glazing and suitable aspect ratios, can significantly improve thermal comfort and reduce cooling energy consumption in hot arid residential contexts.

Many similarities can be observed among the timber structures that were built in ancient Japan, China, and Korea, bearing witness to the exchanges between these countries. Japan and China had technical manuals that contributed to the development of architecture in each country. Korea might also have had such manuals, but none have been found. In this study, the author analyzed a Chinese technical manual, the Yingzao Fashi, to derive its system for determining the proportions of architectural elements. The author then applied this system to the dimensions of historic buildings in Korea and Japan to obtain insights into proportionality in Chinese, Japanese, and Korean architectural elements.

While increasingly popular for their aesthetic appeal and energy efficiency, reflective materials may also create harsh glare, disorientation, and psychological strain. Despite their prevalence in modern architectural design, the impact of these facades on mental well-being remains underexplored. Drawing from environmental psychology and perceptual science, this study assesses how different reflective materials influence both visual perception and psychological response, particularly among residents and students in Leicester. Two contrasting case studies, the reflective metal Highcross centre facade and the reflective glass Mattioli Woods PLC facade, served as focal points. Using a structured online questionnaire incorporating visual stimuli and Likert-scale questions, responses from 30 participants were analysed using descriptive and statistical analysis (i.e., one-way ANOVA) to determine differences in visual discomfort (due to brightness, glare, or shine), visual attractiveness, visual disorientation, and perception of the surroundings, as well as the associated physiological responses such as stress, tension, and mood. Results show that the Highcross Centre facade was consistently perceived as more visually discomforting and disorienting than the Mattioli Woods facade, with statistically significant differences. However, both facades were rated similarly high for visual interest, suggesting that aesthetic value can coexist with discomfort. Finally, the analysis shows that buildings’ reflective facades evoke only low levels of perceived stress, tension, or unease, with median scores remaining low overall. These findings highlight the importance of human-centred facade design, suggesting that, as cities adapt to climate change, architects and urban planners consider not only environmental performance but also perceptual and psychological effects.

Natural ventilation could be established as an effective passive design strategy for increasing air changes per hour in a built environment. Modern air conditioning systems often fail to provide sufficient fresh air, potentially causing health issues for occupants. In contrast, natural ventilation offers an effective alternative for maintaining sufficient indoor air quality in buildings. This study explores the application of grouped airfoil arrays on building façades as an innovative passive design to enhance the air change rate. Numerical simulations were conducted to analyze various airfoil configurations, determining the most effective design for building a façade. Three groups, including symmetrical, semi-symmetrical, and flat-bottomed grouped airfoils, were selected according to their aerodynamic properties and potential impacts on airflow dynamics. For this purpose, a typical high-rise residential building was selected as a case study for field measurement and CFD simulation. The results indicated that symmetrical airfoil arrays could increase the air changes per hour (ACH) up to 23 times per hour with a wind velocity of 0.37 m/s at 10 m above ground, whereas their bidirectional performance ensured stable airflow regardless of wind direction. Although semi-symmetrical airfoil arrays maximize air capture and induce beneficial turbulence, the ACH within a residential unit was boosted up to 16 times per hour under the same outdoor wind velocity conditions. The ACH was 14 times per hour for the flat-bottom airfoils, serving as a comparative baseline and providing insights into the performance advantages of more complex designs. Full article

Climate change threatens the sustainability of historic buildings with increasing extreme weather events, making energy resilience critical. However, studies on energy resilience often lack forward-looking, holistic approaches. This study aims to develop a conceptual framework that includes how Artificial Intelligence (AI) technologies can support energy resilience in historical buildings with data-driven prediction and analysis to increase energy resilience against climate change. This study applied a methodology with four-stage qualitative research techniques, including a systematic literature review (PRISMA method), content analysis, AI integration, and conceptual framework development processes, in the intersections of historical building, energy resilience, and climate change. The findings reveal a significant research gap in the predictive analysis of the resilience of historic buildings and the integration of AI-based tools in the context of climate change. The proposed framework outlines a multi-layered system that includes data collection, performance analysis, scenario-based prediction, and AI-assisted decision-making, aiming to enhance the resilience of the building (including building envelope, thermal, and lifecycle analysis). Consequently, this study provides a theoretical and methodological perspective and proposes a scientifically based and applicable roadmap. It also highlights the potential of AI as a bridge between energy resilience and historical buildings in the face of a rapidly changing climate. Full article

Authenticity in heritage conservation is theoretically and practically complex, dynamic and frequently contested. In conservation practice, through the decisions directing the processes of protection, restoration, adaptation, presentation and interpretation, there will be multiple interpretations of what denotes authenticity, and what is considered to be authentic by different actors. The purpose of the paper is to discuss alternative approaches to the determination of authenticity within the framework of current day conservation theories and heritage discourses. In this paper I propose that authenticity is situation specific and exists on a scale and as such is determinable using cultural perspectives and value-based assessment tools. Positioning authenticity as being dynamic and situation-specific, this research sets out to construct a framework through which the different perspectives involved in decision making are better acknowledged and the determinants of authenticity can be more clearly captured. The research utilizes the context of urban heritage conservation in the Arabian Peninsula to demonstrate how different approaches to conservation are evaluated in terms of authenticity. Full article

Despite a global trend toward socially engaged higher education, architectural pedagogy continues to grapple for a coherent approach that systematically and genuinely integrates socio-cultural dimensions into design studio teaching practices. Defined as the interwoven social, cultural, and political factors that shape the built environment, the socius is treated peripherally within architectural pedagogy, limiting students’ capacity to develop civic agency, spatial justice awareness, and critical reflexivity in navigating complex societal conditions. This article argues for a socius-centric reorientation of architectural pedagogy, postulating that socially engaged studio models, which include Community Design, Design–Build, and Live Project, must be conceptually integrated to fully harness their pedagogical merits. The article adopts two lines of inquiry: first, mapping the theoretical underpinnings of the socius across award-winning pedagogical innovations and Google Scholar citation patterns; and second, defining the core attributes of socially engaged pedagogical models through a bibliometric analysis of 87 seminal publications. Synthesising the outcomes of these inquiries, the study offers an advanced articulation of studio learning as a process of social construction, where architectural knowledge is co-produced through role exchange, iterative feedback, interdisciplinary dialogue, and emergent agency. Conclusions are drawn to offer pragmatic and theoretically grounded pathways to reshape studio learning as a site of civic transformation. Full article

This paper presents the development and structure of a geospatial (work in progress), architectural heritage database designed to document, interpret, and valorize Second World War military fortifications in Sardinia. Currently hosting over 1800 georeferenced entries—including bunkers, artillery posts, underground shelters, and camouflage systems—the database constitutes the analytical core of an interdisciplinary research framework that interprets these remnants as a coherent wartime palimpsest embedded in the contemporary landscape. By integrating spatial data, archival sources, architectural features, conservation status, camouflage typologies, and both analog and digital graphic representations, the system operates as a central infrastructure for multiscale heritage analysis. It reveals the interconnections between dispersed military structures and the wider territorial fabric, thereby laying the groundwork for landscape-based interpretation and site-specific reactivation strategies. More than a cataloging tool, the database serves as an interpretive and decision-making interface—supporting the generation of cultural itineraries, the identification of critical clusters, and the design of adaptive reuse scenarios. While participatory tools and community engagement will be explored in a second phase, the current methodology emphasizes landscape-oriented reuse strategies based on the perception, spatial storytelling, and contextual reading of wartime heritage. The methodological synergy between GIS, 3D modeling, traditional drawing, and archival research (graphic and photographic documents) contributes to a holistic vision of Sardinia’s wartime heritage as both a system of knowledge and a spatial–cultural resource for future generations.

This study investigates how augmented-reality (AR) technology can enhance the presentation and preservation of cultural heritage, using Kayseri Castle as a case study. Although previous studies have explored AR applications in heritage contexts, few have addressed their role in representing multi-layered architectural histories of complex sites. The research focuses on the development and evaluation of the KAISAREIA-AR application, which integrates historical, architectural, and cultural narratives into an interactive AR platform. By reconstructing the castle’s distinct historical layers—spanning the Roman, Seljuk, Ottoman, and Republic periods—the study seeks to assess AR’s effectiveness in providing immersive visitor experiences while maintaining the authenticity of heritage sites. Three-dimensional models of the castle were created using 3ds Max, enriched with visual and auditory information, and deployed via Unity software on wearable AR devices. The study employed the Unified Theory of Acceptance and Use of Technology (UTAUT) framework and Structural Equation Modeling (SEM) to evaluate the application’s usability and impact on user engagement. The findings indicate that AR significantly enhances the accessibility, understanding, and appreciation of cultural heritage by providing dynamic, immersive experiences. The KAISAREIA-AR application demonstrated its potential to bridge historical authenticity with modern technology, offering a replicable model for integrating AR into cultural heritage conservation and education.

Residents’ values in social housing retrofit extend beyond energy efficiency targets to encompass complex social and physical considerations, shaping their acceptance and experience of interventions. These values appear to influence retrofit success yet are often overlooked in policy and practice that prioritise technical performance. This paper investigates what residents value in social housing retrofit through a focus group method with the Sutton Estate in London, combining institutional stakeholder (housing association and architect) and resident perspectives. Content analysis of focus group questionnaires, discussions, and consensus-building activities revealed four key resident values: (1) good stakeholder relationships, emphasising trust-building through personal connections; (2) access to information, requiring clear, continuous communication through multiple channels; (3) comfort, health, and safety, integrating physical and mental wellbeing; and (4) building and community longevity, focusing on preserving building character and social sustainability. The findings suggest that social housing retrofit may benefit from a holistic approach integrating residents’ values throughout the project lifecycle, addressing the social, physical, and long-term sustainability of homes and communities. The findings highlight the importance for housing associations, architects, and policymakers to consider residents’ values when developing retrofit strategies, balancing technical requirements with residents’ needs and priorities.

Lion Grove was established in 1342 during the Yuan Dynasty and is one of the four most famous classical gardens in China. It was recognized as a UNESCO World Heritage Site in 2000. Although Lion Grove is now regarded as a private garden representing the culture of Confucian scholars, it was originally a Chan Buddhist garden during its inception in the Yuan Dynasty. This study examines the natural landscapes of Lion Grove at its inception, focusing on four main aspects: the philosophy of nature, planning intent, creators, and the philosophical ideas they represent. Key findings include the following: Firstly, Lion Grove’s attitude towards nature is rooted in China’s indigenous culture, making it both a physical expression of Chan philosophy and a space reflecting the scholar–bureaucrats’ vision of an ideal landscape. Secondly, from the perspective of landscape planning, the Lion Grove of the Yuan Dynasty placed greater emphasis on natural elements compared to its modern counterpart, with rock landscapes serving as the core element throughout the garden. Thirdly, hermitic philosophy emerged as a significant cultural theme alongside Chan Buddhism during the Yuan Dynasty. Fourthly, the landscape elements of Lion Grove symbolize Chan Buddhist wisdom and the hermit’s idealism, with poetry playing a key role in conveying these cultural ideals, preserving the site’s early philosophical significance.

Public open spaces have recently attracted significant attention in the national development programs aimed at improving urban livability and quality of life in Saudi Arabia. While many studies have examined the design quality of public open spaces in the country, a contextualized evaluation index that takes into account users’ preferences and the nation’s social context is still lacking. This gap calls for additional field studies to better understand users’ needs and their interactions with the current urban design practices of public open spaces. This study provides deeper insights into the design quality of public open spaces in Saudi Arabia. The study first identified 16 attributes of design quality of public open spaces, and then assessed a case study, Alrabie Park in Al-Khobar city, based on field observation and a survey of users’ satisfaction levels in relation to these quality attributes The findings revealed that the average of users’ satisfaction was 3.76 out of 5.0, indicating a neutral to satisfied response. Key strengths were noted in accessibility and users’ comfort, while areas needing improvement included environmental quality and amenities and services. The study recommends the development of a national evaluation index for public open spaces to create inclusive, safe, and vibrant environments that reflect Saudi Arabia’s urban and socio-cultural context. It also emphasizes the importance of community engagement in this regard to ensure that the design of public spaces aligns well with the users’ needs and helps to create sustainable urban spaces in the city.

Addressing the growing demand for affordable housing requires innovative solutions that strike a balance between cost efficiency and user-specific needs. Mass customization (MC) presents a promising approach that enables the creation of tailored housing solutions on a scale. In this context, this study introduces a model for mass customization of affordable single-family housing units in the city of Teresina, PI, Brazil. Our approach integrates algorithmic–parametric modeling and BIM technologies, facilitating the flow of information and enabling informed decision-making throughout the design process. Since the early design stages, the work has assumed that these integrated technologies provide real-time control over design variables and associated construction data. To develop the model, the method proceeded through the following phases: (1) analysis of the context and definition of the design language; (2) definition of the design process; (3) definition of the cost calculation method and estimation of construction time; (4) definition of the computing model based on the specified technologies; and (5) quantitative and qualitative evaluation of the computational model. As a result, this research aims to contribute to the state-of-the-art by formalizing the knowledge generated through the systematic description of the processes involved in this workflow, with a special focus on the Brazilian context, where the issue of social housing is a critical challenge.

In the age of artificial intelligence (AI), architectural practice faces a paradox of immense potential and creeping standardization. As humans are increasingly relying on AI-generated outputs, architecture risks becoming a spectacle of repetition—a shuffling of data that neither truly innovates nor progresses vertically in creative depth. This paper explores the critical role of data in AI systems, scrutinizing the training datasets that form the basis of AI’s generative capabilities and the implications for architectural practice. We argue that when architects approach AI passively, without actively engaging their own creative and critical faculties, they risk becoming passive users locked in an endless loop of horizontal expansion without meaningful vertical growth. By examining the epistemology of architecture in the AI age, this paper calls for a paradigm where AI serves as a tool for vertical and horizontal growth, contingent on human creativity and agency. Only by mastering this dynamic relationship can architects avoid the trap of passive, standardized design and unlock the true potential of AI. Full article
