Sustainable building rating tools (SBRTs) are essential for assessing the environmental impact of buildings, continuously evolving to meet the needs of users. In Nigeria, the effectiveness of these tools depends on their ability to meet the country’s sustainable building standards and environmental goals. While adopting sustainable building rating tools is crucial for realizing the benefits of sustainable construction, little is known about their actual utilization in the Nigerian construction industry. This research aims to (1) assess the level of awareness and utilization of sustainable building rating tools among diverse stakeholders—including architects, engineers, sustainability consultants, developers, contractors, and suppliers—within Nigeria’s Architecture, Engineering, and Construction (AEC) sector, and (2) explore drivers and barriers to their use. The study adopts an explanatory sequential mixed-methods design, starting with a survey of 98 Nigerian building professionals, followed by qualitative analysis. Results show that while 72.4% were aware of SBRTs, only 39.8% had used them, highlighting a gap between awareness and application. Utilization was higher among professionals with greater experience, income, and education. Barriers included high certification costs, tool complexity, and socio-economic factors, while key drivers were government regulations and environmental benefits. The study calls for targeted education, tool simplification, and financial incentives to boost adoption and promote sustainable construction in Nigeria. Full article

Climate change places urban coastlines at significant risk from rising sea levels and increasing storm intensity and frequency. This paper uses Red Hook, Brooklyn, NY as a case study to identify knowledge gaps in current climate resilience efforts across low-lying, post-industrial landscapes in coastal cities. Through an analysis of the short- and long-term effects of Superstorm Sandy (29 October 2012), current city planning efforts, and resulting architectural adaptations, this paper uncovers the shortcomings and possible maladaptive planning in Red Hook and New York City’s overall coastal resilience efforts. As a response to these findings, a new framing for future resilience efforts is proposed through speculative student design proposals and international case studies, applying a more dynamic understanding of climate resilience. These proposals envision a future climate-resilient, heterogeneous model for post-industrial coastal neighborhoods, transitioning to urban landscapes that embrace their shifting shorelines. This paper’s conclusion argues that effective coastal resilience requires strategies that work at multiple scales with shifting water–land boundaries rather than against them. Full article

This paper explores the evolving relationship between Digital Twins (DT) and the Metaverse, two foundational yet often conflated digital paradigms in digital architecture. While DTs function as mirrored models of real-world systems—integrating IoT, BIM, and real-time analytics to support decision-making—Metaverses are typically fictional, immersive, multi-user environments shaped by social, cultural, and speculative narratives. Through several research projects, the team investigate the divergence between DTs and Metaverses through the lens of their purpose, data structure, immersion, and interactivity, while highlighting areas of convergence driven by emerging technologies in Artificial Intelligence (AI) and Extended Reality (XR).This study aims to investigate the convergence of DTs and the Metaverse in digital architecture, examining how emerging technologies—such as AI, XR, and Large Language Models (LLMs)—are blurring their traditional boundaries. By analyzing their divergent purposes, data structures, and interactivity modes, as well as hybrid applications (e.g., data-integrated virtual environments and AI-driven collaboration), this study seeks to define the opportunities and challenges of this integration for architectural design, decision-making, and immersive user experiences. Our research spans multiple projects utilizing XR and AI to develop DT and the Metaverse. The team assess the capabilities of AI in DT environments, such as reality capture and smart building management. Concurrently, the team evaluates metaverse platforms for online collaboration and architectural education, focusing on features facilitating multi-user engagement. The paper presents evaluations of various virtual environment development pipelines, comparing traditional BIM+IoT workflows with novel approaches such as Gaussian Splatting and generative AI for content creation. The team further explores the integration of Large Language Models (LLMs) in both domains, such as virtual agents or LLM-powered Non-Player-Controlled Characters (NPC), enabling autonomous interaction and enhancing user engagement within spatial environments. Finally, the paper argues that DTs and Metaverse’s once-distinct boundaries are becoming increasingly porous. Hybrid digital spaces—such as virtual buildings with data-integrated twins and immersive, social metaverses—demonstrate this convergence. As digital environments mature, architects are uniquely positioned to shape these dual-purpose ecosystems, leveraging AI, XR, and spatial computing to fuse data-driven models with immersive and user-centered experiences.

The artisanal production of paints using inorganic pigments from the Cusco Valley is considered a sustainable alternative to the use of synthetic industrial paints. This approach not only helps reduce the environmental footprint associated with the use of volatile organic compounds (VOCs) but also utilizes local materials. The present study evaluates the physical and mechanical properties of paints obtained from natural pigments through standardized tests based on the American ASTM standards, focusing on adhesion (ASTM D-3359), drying time (ASTM D-1640), surface hardness (ASTM D-3363), and the performance of the paints when exposed to the environmental factors of Cusco (under real conditions). In this regard, the pigments were extracted from traditional quarries and processed through the sedimentation method (MS) and ball milling (MG). The produced paints were formulated with the addition of polyvinyl acetate (PVA) as a binder and water as a solvent and were applied to standardized panels. The results show that all samples meet the requirements of the technical parameters, demonstrating good adhesion, appropriate drying times, and acceptable hardness for architectural coatings, Chromatic variations (ΔE*) were recorded depending on the processing method and the level of environmental exposure, with paints containing ground pigments (MG) being more resistant to fading. This study concludes that these artisanal formulations represent a technically viable and culturally relevant alternative to industrial coatings, especially in contexts of heritage restoration or sustainable architecture.

Buildings account for a significant portion of global energy consumption and are increasingly vulnerable to the adverse effects of climate change, including rising greenhouse gas emissions and shifting weather patterns. These disruptions significantly impact energy demand, necessitating proactive measures to ensure buildings remain functional, sustainable, and energy efficient. This study offers a novel contribution by systematically comparing the energy performance of office building prototypes using a simulation-based method across all U.S. climate zones under projected Representative Concentration Pathways (RCPs) 4.5 (moderate emissions) and 8.5 (high emissions) for the years 2050 and 2080. This multi-scale and multi-scenario simulation provides a nationally comprehensive view of how building size and climate conditions interact to influence vulnerability to future energy demand shifts. The findings reveal that medium-sized office buildings are the most vulnerable to climate change, with an average Energy Unit Intensity (EUI) increase of 12.5% by 2080 under RCP 8.5, compared to a 7.4% rise for large office buildings and a slight decline of 2.5% for small office buildings. Hot and humid cities such as Miami, FL, experience the highest increases, with EUI projected to rise by 21.2% for medium offices, while colder regions like Fairbanks, AK, show reductions of up to 18.2% due to decreasing heating demands. These results underscore the urgent need for climate-compatible building design strategies, particularly in high-risk areas. As climate change intensifies, integrating resilience-focused policies will safeguard energy systems and ensure long-term occupant comfort. Full article

Architecture as a STEM career presents a promising yet challenging path for women pursuing professional growth in the field, as they remain under-represented, particularly in leadership roles and professional practice, despite their increasing presence in architectural education. This study investigates the experiences, motivations, and challenges faced by women in architecture in the educational setting of Nigeria. Using a quantitative research approach, data were collected from 137 respondents through structured questionnaires, representing a 97.93% response rate. The findings reveal that passion for design and creativity (73.7%) was the predominant motivation for women choosing architecture. While 80.5% of respondents reported experiencing or observing gender-related challenges, these were not ranked as primary barriers when specific obstacles were identified; instead, financial constraints, limited resource access, and work–life balance emerged as the most significant challenges. Remarkably, 89.5% of participants expressed satisfaction with architecture as a career choice, with no reported dissatisfaction. Creativity (28%), continuous learning (24.2%), and societal impact (20%) were found to be the most rewarding aspects of their architectural careers. Statistical analyses revealed no significant association between academic level and career satisfaction or between institution attended and experiences of gender-related challenges. The correlation analysis demonstrated that intrinsic motivators like passion for design have stronger relationships with career satisfaction than extrinsic factors like financial stability or family influence. These findings contribute to understanding women’s experiences in architectural education in Nigeria and have implications for educational institutions, professional organizations, and policymakers seeking to enhance women’s participation and advancement in architecture. The research highlights the importance of addressing structural barriers while nurturing the creative and professional aspects that draw women to the field. Full article

The practice of architectural design is experiencing disruptive changes—e.g., the incredible growth of architects worldwide, the relevance of social media and the impact of artificial intelligence—typically analysed and studied as separate phenomena. Through a narrative research approach, this paper connects these emerging trends into a systemic view by referring to two conceptual frameworks—systems theory and transcendental phenomenology. Thus, it shows their mutual irritations, investigating the consequences of the practice of design and the collective architectural imaginary and mapping out the main findings through two diagrams. This paper recognises a series of key points of the resulting architectural system, the paramount being the extensive and mainly unconscious use of keywords. Then, clarifying the ontological dual nature of keywords, it conjectures that design will evolve differently for ordinary cases—characterised by passive keywords and competence—and for the most extraordinary ones—where mastery will have a critical role through active keywords.

The worldwide energy crisis is causing people in most countries to reduce their energy use to prevent the next generation from being unable to fulfill their needs. The Osing people use sustainability values based on traditions passed down from generation to generation with appropriate technology to fit the needs of the people and their environment. This research employs a qualitative descriptive method with a literature review and data collection. Based on the framework used by Iwanmura, Osing house construction primarily focuses on the principles of low impact and health and amenity. This study reveals that the architectural design and construction process of an energy-efficient traditional building can be adapted to contemporary sustainable housing. The primary aim was to identify and analyze sustainability values in the construction process and techniques of traditional Osing houses in Kemiren Village, Banyuwangi, which can serve as a reference for modern sustainable architecture practices. The study reveals the uniqueness of traditional Osing construction using the local material Bendo wood, which can be dismantled from the foundation up to the roof joint systems, thus allowing the materials to be repaired and recycled down to the smallest parts and minimizing construction waste. The advantage of this building construction process is the use of traditional housing techniques to minimize the need for mechanical systems. This traditional construction method, using wood as the building material and considering climatic features, demonstrates how to achieve sustainable building values throughout all elements of a building that provides users with comfort and safety.

Climate change is a pressing global challenge, significantly influenced by human actions. Considering that buildings account for approximately 40% of total US energy use in the United States, this study examines how humanized energy labeling can influence home buyers’ preferences, shaping total energy demand and usage. “Humanized energy and carbon data” refers to the simplification of complex energy metrics into accessible formats for non-expert audiences. By presenting energy data in a user-friendly manner, this approach aims to empower consumers to prioritize energy-efficient buildings, consequently driving demand for sustainable practices in the building sector. To test this approach, a survey of 163 participants was conducted. Participants were presented with six building façade designs in two rounds: one without energy, carbon, or utility cost data, and the second with comprehensive performance information. Results revealed that 77.3% of participants shifted their preferences after reviewing energy-related data. Furthermore, the study found consistent impacts across demographic groups, highlighting the broad applicability of humanized labeling. These findings confirm the potential of humanized energy labeling to influence housing decisions, driving demand for sustainable practices in real estate. By empowering consumers with accessible information, this approach contributes to mitigating climate change while fostering informed decision-making in the housing market. Full article

Digital Twins (DTs) of buildings can generate large volumes of dynamic data from various sources (e.g., sensors and IoT devices), enabling real-time representation of physical building states in a digital environment. Although machine learning (ML) techniques are increasingly used to predict building energy consumption from this DT data, existing approaches often lack scalability in handling data growth (data scalability) and/or adapting to evolving data patterns (model scalability). This study aims to address both drawbacks by developing a scalable cloud-based framework for the prediction of the building energy consumption. A key contribution to the field is the inclusion of a “monitoring and maintenance” module, which continuously evaluates model performance and triggers retraining only when needed. This enables timely adaptation of the ML model while avoiding unnecessary retraining and the associated computational costs. The framework was implemented and tested in a case study of a commercial building for 90 days, demonstrating its applicability. In a practical setting, the developed model could detect anomalies in time when the accuracy declined below the set threshold (70%) for five days and prevented unnecessary retraining of ML models. The findings support the feasibility of using cloud-based approaches to implement scalable ML models for energy prediction in buildings. Full article

The natural environment plays a vital role in children’s health, influencing their physical, emotional, social, psychological, and spiritual well-being. Maintaining a continuous relationship with nature is essential for children and is a key consideration for professionals, such as architects, urban and interior designers, and landscape architects. School design should balance students’ abilities and environmental challenges and offer opportunities to alleviate mental fatigue, supporting sustained learning. The well-known architectural approach, biophilic, fostering a stronger connection between nature and humans, can significantly enhance students’ learning experiences and mental health in school settings. However, implementing this style in Iranian primary schools has largely been overlooked despite its potential to develop a more peaceful and dynamic environment. This research ranked several schools in northern Iran based on biophilic criteria to help authorities identify which schools require improvements. To this end, biophilic design elements in schools were identified through a literature review and provided to research experts. The most important criteria for evaluating and prioritizing options (schools) were selected based on their opinions. Subsequently, each criterion’s importance (weight) was determined using pairwise comparisons, and, finally, the schools were prioritized using the TOPSIS method. Full article

The urban landscape of the Russian Arctic, shaped during the Soviet era of extensive urbanization, embeds narratives of colonial appropriation and serves as the foundation for ongoing urban development. In light of climatic, political, and social uncertainties, design disciplines must navigate the balance between environmental sustainability and the varied needs of residents, requiring a systemic approach to design. This study combines theoretical analysis with qualitative field research conducted in two Western Siberian cities (Novyy Urengoy and Tarko-Sale), including interviews, mental mapping, and systematic observation of urban life. Analysis of the collected data revealed significant challenges in current urban design practices, particularly regarding weather protection, seasonal adaptation, and social space creation. The proposed model constitutes a pioneering initiative in domestic Arctic urban research, aiming to conceptualize a context-sensitive approach to urban environmental formation, thereby challenging prevalent universal/mainstream methodologies and establishing a theoretical framework for future applications. Our theoretical model synthesizes representations, perceptions, and materiality, conceptualizing the architectural environment as a context-sensitive “life-support module”. This conceptualization emphasizes that successful Arctic urban design must emerge from specific local contexts rather than universal solutions, as demonstrated by our analysis of residents’ spatial practices and adaptations to extreme conditions. We reference media studies to analyze urban materiality as both an artificial construct that mediates perceptions of the immediate surroundings and as a generative force that actively shapes meanings, practices, and sensations. Our findings indicate that current standardized approaches to Arctic urban development often fail to address local needs and environmental conditions, suggesting the necessity for a fundamental shift in design methodology. Given that the urban realm is a fundamental component in shaping individual and collective perceptions, this conceptual shift has the potential to significantly influence prevailing societal views of the “empty” and “hostile” Arctic.

Tactical urbanism (TU) and Virtual Reality (VR) both aim to reimagine physical spaces, with TU utilizing rapid, temporary, scalable, and cost-effective physical interventions to test and refine urban design, while VR offers immersive virtual environments for exploration and analysis. This article investigates the integration of VR with TU to address challenges in effectively communicating and evaluating temporary urban interventions. This study is grounded in a literature review on spatial perception, TU, and VR, followed by an empirical experiment involving Brazilian college students. Participants interacted with a parklet installation in both physical and virtual environments, with their spatial perception and emotional responses evaluated using the AR4CUP (Augmented Reality for Collaborative Urban Planning) protocol. The results demonstrated that VR positively impacts the perception, usability, and social dynamics of urban spaces. Participants emphasized the importance of social interaction and recreational activities, reinforcing VR’s potential to simulate and refine urban interventions. A crucial avenue for future research is identifying best practices for using VR as a platform for collaborative design and decision-making. This step could enhance VR’s effectiveness in creating public spaces that align with community needs, fostering participatory planning and promoting inclusive, functional, and enriching environments.

Sustainability has become an important focus in the construction industry due to growing environmental concerns, resource depletion, and the urgency to reduce greenhouse gas emissions. The construction sector contributes significantly to the world’s carbon emissions and energy consumption, making it a prime candidate for sustainable transformation. In response to these challenges, there has been a shift towards utilizing earth-based products, especially earth blocks, as sustainable alternatives. Compressed stabilized earth blocks (CSEBs) are garnering increased attention because of their ability to lower environmental impact. These blocks are made from locally sourced materials, reducing the transportation-related emissions and energy use. Their production processes typically require far less energy than traditional building blocks, which results in reduced carbon footprints. Earth blocks also contribute to sustainability through their thermal performance, which can enhance energy efficiency in buildings by naturally regulating indoor temperatures. As a result, less artificial heating and cooling is required, leading to further energy savings. Furthermore, CSEBs and other earth blocks can incorporate waste materials promoting a circular economy and resource efficiency. This paper explores the multifaceted role of earth blocks in sustainable construction by conducting a comprehensive systematic and bibliometric analysis. By evaluating research trends, the evolution of the field, and the broader impact of these materials, this study aims to provide a deeper understanding of the contributions of earth blocks to sustainability. Key areas of focus include identifying prominent research themes, emerging technologies, and future opportunities for incorporating earth blocks into mainstream construction practices. This approach aligns with the vision of advancing sustainable architecture and green buildings to minimize environmental pollution and resource consumption while supporting the transition to a circular economy in the built environment.

The building sector, responsible for 40% of global energy consumption, faces increasing demands for sustainability and energy efficiency. Accurate energy consumption forecasting is essential to optimise performance and reduce environmental impact. This study introduces a hybrid machine learning framework grounded in Sparse, Interpretable, and Transparent (SIT) modelling to enhance building energy management. Leveraging the REFIT Smart Home Dataset, the framework integrates occupancy pattern analysis, appliance-level energy prediction, and probabilistic uncertainty quantification. The framework clusters occupancy-driven energy usage patterns using K-means and Gaussian Mixture Models, identifying three distinct household profiles: high-energy frequent occupancy, moderate-energy variable occupancy, and low-energy irregular occupancy. A Random Forest classifier is employed to pinpoint key appliances influencing occupancy, with a drop-in accuracy analysis verifying their predictive power. Uncertainty analysis quantifies classification confidence, revealing ambiguous periods linked to irregular appliance usage patterns. Additionally, time-series decomposition and appliance-level predictions are contextualised with seasonal and occupancy dynamics, enhancing interpretability. Comparative evaluations demonstrate the framework’s superior predictive accuracy and transparency over traditional single machine learning models, including Support Vector Machines (SVM) and XGBoost in Matlab 2024b and Python 3.10. By capturing occupancy-driven energy behaviours and accounting for inherent uncertainties, this research provides actionable insights for adaptive energy management. The proposed SIT hybrid model can contribute to sustainable and resilient smart energy systems, paving the way for efficient building energy management strategies. Full article

In the image era, architectural drawing gradually evolved from being a part of traditional architectural design to an artistic form with independent aesthetic value. However, a systematic evaluation method for this unique art form is still lacking. This study analyzes the works of four Chinese and Japanese architects, focusing on the functionality and artistry of architectural drawings. Combining iconography, semiotic analysis, and theories from visual culture studies, it explores the visual language and cultural significance embedded in architectural drawings from a new perspective and attempts to establish an evaluation framework. The analysis of visual symbols, cultural codes, and social contexts reveals how architects convey architectural concepts, historical memories, and urban landscapes through their drawings. This study finds that architectural drawings not only convey architectural information but also integrate cultural narratives and artistic expression, serving as an important intersection between architecture and other disciplines. Although interpretations may vary across cultural contexts, the semiotic approach offers a relatively objective evaluation system. This research helps architects, artists, and educators better understand the role of architectural drawing and promotes its application in architectural design, artistic creation, and education.
