Special Issue Information

Dear Colleagues,

Currently, we are consuming more than 1.7 times the Earth's total capacity to provide renewable and non-renewable resources to humanity (GFN, 2023). If no technological and policy changes are introduced, we will need almost three planets by 2050 to meet the demand of 9.6 billion people (GFN, 2023). Building construction industries are resource-intensive as they consume 25% of virgin wood and 40% of non-renewable resources, including raw stone, gravel, and sand, globally each year for cement, aggregates, and pavement production (Kedir, 2020). These non-renewable resources will become scarce with the rapid growth of population and the economy. Buildings alone are responsible for 39% of global energy-related greenhouse gas emissions, of which, 28% is operational energy produced from the combustion of fossil fuels, and the remaining 11% is produced by the manufacturing of materials and construction activities (WGBC, 2023). Without implementing further environmental policy, the energy used in buildings could increase by 46–73% compared to its 2019 level by 2050; this will be driven by population growth, greater diffusion, and the utilization of energy-intensive devices, and enhanced living standards in developing countries (Camarasa et al. 2022). The United Nations estimates that 68% of the world's population will live in urban areas by 2050 (Peña et al. 2021). This will extend the impact of urban heat islands as structures such as buildings, roads, and other infrastructure will absorb and re-emit the sun’s heat more than forests and water bodies (USEPA, 2022).  

This Special Issue (SI) aims to publish a wide range of articles that address topics including innovative building design, energy efficiency/efficient end-use appliances, resource conservation, alternative construction materials, innovative or smart building management, sustainability assessment tools, green energy, and the urban micro-climate; these contributions will address the sustainability challenges of building industries in the 21st century.

This research investigates integrating Building Information Modeling (BIM) and blockchain technology to enhance building information’s security, reliability, and accuracy in Martian environments. Given the unique challenges posed by extraterrestrial construction, this study evaluates the feasibility of this hybrid approach through a structured SWOT (Strengths, Weaknesses, Opportunities, and Threats) analysis. Expert inputs were collected through a comprehensive questionnaire identifying nine strengths, eight weaknesses, eight opportunities, and six threats to implementing BIM and blockchain technology in space projects. The Analytical Hierarchy Process (AHP) was used to prioritize these factors. Findings indicate that the strengths are cost calculation and budgeting (26.21), and the weaknesses are technology complexity (25.488). Increased productivity (19.16) is the most important criterion at the opportunity point, and defects in data security (20.68) are the most important at the threat point. The SWOT analysis places BIM and blockchain integration in a conservative strategy quadrant, indicating that the technology holds significant promise but requires further development and refinement. Ultimately, this research contributes to the growing knowledge about extraterrestrial construction technologies and provides a foundation for developing flexible and autonomous building systems for Martian habitats.

Poor information management is predominant in construction projects and tends to have a negative effect on project outcomes. The use of technology, in particular building information modelling (BIM), has been promoted to address information management issues. However, the adoption of BIM is fraught with challenges, such as a lack of standardisation and difficulties in effectively adopting standards such as ISO 19650. This research aims to deepen knowledge and improve the management of BIM standards, particularly in using ISO 19650 to collaboratively deliver construction projects by applying process modelling techniques. By employing a mixed-methods approach that combines document analysis and qualitative interviews, this study critically examines the principles and requirements of ISO 19650 and their practical implications. It focuses on how process modelling can clarify complex concepts and improve information management. The findings indicate that process modelling significantly aids in comprehending ISO 19650, making its intricate concepts more accessible to multidisciplinary teams, enhancing stakeholder communication, improving project execution efficiency, and reducing errors and rework. Furthermore, this research emphasises the need to distinguish ISO 19650-derived elements from those adapted from other sources to ensure transparency and integrity in project management practices. The main implications of this study are two-fold. From a research perspective, it contributes to the academic discourse by addressing a critical gap in the literature, which has largely focused on BIM technology implementation rather than the processes and workflows necessary for effective standard adoption. From a practical perspective, this study promotes transparency and integrity in project management practices, enabling organisations to adopt and adhere to standardised practices more effectively in collaborative environments.

Emerging building information modelling (BIM) can be complex to teach during a regular face-to-face class schedule, and even more challenging remotely or virtually. This has been further exacerbated by the outbreak of COVID-19 whereby the adoption of virtual teaching techniques in higher education has been strongly recommended. However, since the outbreak, in December 2019, there has been a paucity of research with regards to experiences with the virtual delivery of BIM. This study explores lessons learnt in engaging students through the virtual delivery of BIM courses during the COVID-19 pandemic. Quantitative data from a questionnaire and quantitative and qualitative data from the various module evaluation reports were used to inform this study. A main finding is that, despite being a technical course, BIM can still be delivered online without compromising any of its learning outcomes. In contrast to existing literature, the main contribution of this study is practical as it provides insights on methods that worked and those that can be used post-COVID-19 in delivering BIM courses. This study provides hope to prospective students, especially distance learning students, who often worry whether the technology aspects of BIM can be taught remotely. Although the study is grounded on BIM and driven by the COVID-19 context and distance learning, it has wider implications for learning and teaching in other technical disciplines and virtual learning in general. Specifically, the experiences and impacts of delivering BIM examined in this study can inform curricula design in other disciplines. Full article

The present study investigates experimental cooling from the ceiling using phase change materials (PCMs) in Yazd, a city characterized by a hot and dry climate. A one-fourth scale model of a real room, measuring 4 m × 3 m × 3 m, was employed for the analysis. To evaluate system performance and the impact of PCM on energy consumption reduction, three configurations were considered: a simple PCM system, a PCM system with a fan (PCM-F), and a PCM system with a mini cooler (PCM-C). Additionally, to assess the influence of window configurations on ventilation, temperature, and comfort conditions within the model, three scenarios were examined: two open windows, one open window, and no windows. The economic analysis compared the two systems with the fan and mini cooler against a full mechanical cooling system without PCMs. Furthermore, CO2 emissions and environmental impacts associated with the systems were also evaluated. The results indicate that the presence of PCMs in the ceiling, due to heat absorption during phase change, leads to a temperature reduction of 5 to 10 °C in the ceiling and a 3.2 °C reduction in the average room temperature compared to the scenario without PCMs. The findings demonstrate that ceiling cooling with PCMs significantly contributes to energy consumption reduction during peak hours of cooling demand. Specifically, the PCM-F system results in a 92% reduction, and the PCM-C system leads to a 71% reduction in total cost compared to the reference mechanical cooling system. Additionally, the PCM-F system achieves approximately a 36% reduction, and the PCM-C system results in a 34% reduction in environmental impact relative to the reference full mechanical cooling system.

The growing demand for sustainable and efficient construction practices has led to an increased interest in modular construction, with design for manufacture and assembly emerging as a pivotal approach. Despite its potential, the integration of design for manufacture and assembly in modular home construction lacks a structured methodology, posing challenges in aligning design, manufacturing, and assembly processes. This paper introduced a framework aimed at systematically incorporating design for manufacturing and assembly principles into modular home production, leveraging different software tools in the design stage for modular design standardization and streamlined manufacturing and assembly processes. Following a mixed-method research methodology, a comprehensive literature review was conducted to identify research gaps. To address these gaps, a framework was developed focusing on design, manufacturing, and assembly considerations, and retrospective validation of the framework was conducted to confirm its effectiveness. This study revealed the significant benefits of integrating design for manufacturing and assembly principles utilizing advanced digital tools, through a hybrid approach using 2D drafting software and 3D BIM software. The findings indicated that implementing design for manufacturing and assembly principles led to a 40% reduction in design phase duration and a 48% decrease in production errors. This paper offers a structured guide for practitioners while providing a basis for further research in sustainable modular construction. Full article

The Fourth Industrial Revolution (Industry 4.0) has profoundly transformed industries worldwide through the integration of advanced digital technologies, including artificial intelligence, digital twins, building information modeling (BIM), and the Internet of Things (IoT). The Architecture, Construction, and Engineering (ACE) sectors are increasingly adopting these innovations to meet the evolving demands of the global market. Within this dynamic context, Saudi Arabia has emerged as a front-runner and significant investor in this sector, as evidenced by the launch of ambitious mega-projects such as NEOM and The Line. These developments prompt valuable discussions about the readiness of graduates to adapt to rapid technological advancements and meet the current demands of the Saudi market. Although numerous studies have explored this issue, the Saudi context presents unique challenges and opportunities due to the accelerated pace of change within the ACE sectors, driven by the goals of Vision 2030. For this reason, this paper aims to address this gap by exploring the readiness of architectural programs in the context of Saudi Arabia to meet the demands of Industry 4.0. To achieve this, a comprehensive literature review was conducted, developing an analytical framework. Subsequently, a multiple-cases approach was employed, with an overall top-level discussion on the undergraduate architecture program subjects available in the five regions in Saudi Arabia. A combination of field observations, domain expertise, and evidence-based coding methods was employed to develop the SWOT analysis. The SWOT framework was utilized to identify key strengths, weaknesses, opportunities, and threats within the current academic programs. The findings were then analyzed in a comprehensive discussion, highlighting necessary transformations in existing programs. The methodology employed in our study involves prolonged engagement and persistent observation to enhance the quality and credibility of the discussion. This paper serves as a roadmap for guiding future educational reforms and aligning architectural education with emerging industry demands and technological advancements in the field. Four key themes are essential for aligning architectural education with Industry 4.0: sustainability in the built environment, innovation and creativity, digital applications in the built environment, and entrepreneurship and leadership in venture engineering. It also strongly emphasized sustainability courses and noted notable deficiencies in preparing students for a digitally driven professional landscape. For example, the average program comprises 162 credit hours and 58 courses, with only six related to Industry 4.0. The top five institutions offering Industry 4.0 courses ranked from highest to lowest are ARCH-U11, ARCH-U8, ARCH-U3, ARCH-U4, and ARCH-U15. ARCH-U11 offers the most Industry 4.0 courses, totaling 15, which account for 26.8% of its courses and 15% of its credit hours, in contrast to ARCH-U20, which offers no courses. The novelty of this research lies in its comprehensive analysis of the readiness of architecture program curricula from 20 Saudi universities to meet the requirements of Industry 4.0. Importantly, these findings support previous studies that established guidelines that mandate the inclusion of sustainability, innovation, and digital skills in architectural education programs. Contribution to the knowledge and findings is valuable for educational institutions, policymakers, and industry leaders, offering insights into evolving architectural education to meet future industry demands and foster technological innovation and sustainable development. Moreover, it provides actionable recommendations for curriculum development in alignment with Vision 2030. Contrary to expectations, findings show that lower-ranked universities offer more Industry 4.0-related courses than higher-ranked ones, emphasizing the need to align university evaluation standards with labor market demands.

This paper presents a numerical study of topology-optimised pin-end aluminium alloy columns using finite element analysis (FEA). The FEA models integrate geometric imperfections and material nonlinearity, and are validated against experimental findings from the existing literature. ABAQUS v.6.15 (release 2020) is used in preparing the FEA models and obtaining the analysis results. Furthermore, modern design methodologies including Eurocode 9, the direct strength method (DSM), and the continuous strength method (CSM) are employed to assess the maximum load capacity of such columns. Parametric investigations encompass diverse parameters such as varied cross-sections, column lengths, and global and local imperfections. By analysing a total of 288 FE models, incorporating 16 column cross-sections across two lengths with nine distinct imperfections, this study compares results with those derived from modern design methodologies. Thus, this research elucidates the behaviour of novel cross-sections and the application of contemporary design techniques in their analysis. Full article

Mastering building thermal science is essential for architectural professionals, as it supports the design of energy-efficient and thermally optimized buildings, which are critical for addressing the growing demands of sustainable architecture. However, traditional teaching methods often disconnect theoretical instruction from practical application, limiting students’ ability to apply core concepts in real-world scenarios. This study introduces a pedagogical reform that integrates design-oriented and inquiry-based experiments, hands-on physical activities, and field-based testing into the teaching of building thermal science. The revised curriculum focuses on applying theoretical principles in real architectural contexts, allowing students to directly design and experience thermal phenomena such as heat transfer and thermal resistance in building envelope structures. To evaluate the effectiveness of this reform, a control group using traditional confirmatory experiments (following predetermined instructions to complete experiments and validate the results) was compared to a reform group engaged in inquiry-based experimental learning. Over the course of three cohorts (2019, 2020, 2021), the reform group consistently outperformed the control group, with statistically significant improvements in average course grades. Specifically, the reform group had mean grade differences of 7.21 points higher in 2019, 4.55 points higher in 2020, and 5.83 points higher in 2021, as demonstrated by t-test results (p < 0.05). The reform group also exhibited more concentrated grade distributions, reflecting enhanced comprehension and retention of key thermal concepts. In addition to improved academic performance, students in the reform group demonstrated superior problem-solving abilities and a heightened awareness of energy conservation and sustainable design practices. This approach not only deepened their understanding of theoretical knowledge but also fostered a greater commitment to integrating sustainability into their architectural projects. Full article

The need to construct environmentally friendly buildings to meet current environmental and ecological standards is urgent. This study introduces a new multi-layer construction material with two outer layers of ordinary mortar and an inner layer of a pozzolane-limes composite to meet this need. The thermal efficiency of this material in building construction is investigated using TRNSYS18 simulations for two distinct climatic zones in Morocco, with a particular focus on its impact on heating dynamics. The primary objective is to evaluate the thermal performance of multi-layered pozzolanic materials, for which mortar samples are meticulously prepared as a reference in the two different climatic zones (Azilal and Errachidia). Using the asymmetric hot plate method under both stable and transient conditions, the authors conduct thermal characterization experiments. The results underscore the improvement in thermal performance made possible by the incorporation of pozzolan as an aggregate in the multi-layer material compared to ordinary mortar. Specifically, thermal conductivity improves significantly, from 0.735 W m−1 K−1 for ordinary mortar to 0.4 W m−1 K−1 for multi-layered pozzolanic materials, representing a 46% mass gain. Additionally, effusivity decreases from 730 to 604 J m−2 K−1 s−1/2, while diffusivity decreases from 3.78 to 2.23 × 10−7 m2 s−1, further attesting to the material’s thermal efficacy. TRNSYS18 simulations corroborate the viability of using multi-layered materials as building envelopes, revealing potential annual heating gains of 25% in Azilal and 5% in Errachidia. These findings underscore the promising prospects of integrating these materials into sustainable construction practices. Full article

Türkiye’s earthquake zone, primarily located along the North Anatolian Fault, is one of the world’s most seismically active regions, frequently experiencing devastating earthquakes, such as the one in Hatay in 2023. Therefore, reconstructing energy-efficient buildings after major earthquakes enhances disaster resilience and promotes energy efficiency through retrofitting, renovation, or demolition and reconstruction. To this end, this study proposes implementing energy-efficient design solutions in dwelling units to minimize energy consumption in new buildings in Hatay, Southern Turkiye, an area affected by the 2023 earthquake. This research focused on a five-story residential building in the district of Kurtlusarımazı, incorporating small-scale Vertical-Axis Wind Turbines (VAWTs) with thin-film photovoltaic (PV) panels, along with the application of a green wall surrounding the building. ANSYS Fluent v.R2 Software was used for a numerical investigation of the small-scale IceWind turbine, and DesignBuilder Software v.6.1.0.006 was employed to simulate the baseline model and three energy-efficient design strategies. The results demonstrated that small-scale VAWTs, PV panels, and the application of a green wall reduced overall energy use by 8.5%, 18%, and 4.1%, respectively. When all strategies were combined, total energy consumption was reduced by up to 28.5%. The results of this study could guide designers in constructing innovative energy-efficient buildings following extensive demolition such as during the 2023 earthquake in Hatay, Türkiye. Full article

In the early stages of building design, decisions are made about the building’s form and envelope, but designers rarely base their decisions on sophisticated energy simulations, even though these features are critical to a building’s energy performance. This paper employs three methods—empirical, parametric, and uncertainty—to assess the interconnectedness of building form, envelope, orientation, and occupancy regarding thermal comfort and energy consumption for heating and cooling a residential building across three regions: Gdyel (mediterranean climate), Oum El Bouaghi, and Constantine (semi-arid climate). The study variables include indoor air temperature, relative humidity, and energy consumption. The initial findings stem from an experiment conducted in an apartment on the top floor of a building in Gdyel, which allowed us to record the evolution of the variables mentioned throughout the year and validate the parametric results of the multi-zone model created in TRNSYS16 software. This study showed that for the considered climates, a compact form is more suitable; it was found that the top floor with SF = 0.57 needs about 30% to 54% more energy than the inter-floor with SF = 0.21. In addition, the heating and cooling methods and habits adopted by Algerian households are responsible for 18% to 35% on the top floor and the inter-floor, respectively. Full article

The transition towards a sustainable future requires the reliable performance of the building’s energy system in order for the building to be energy-resilient. “Energy resilient building in cold climates” is an emerging concept that defines the ability to maintain a minimum level of indoor air temperature and energy performance of the building and minimize the occupant’s health risk during a disruptive event of the grid’s power supply loss in a cold climate. The aim is to introduce an extensive definition of the energy resilience of buildings and apply it in case studies. This article first reviews the progress and provides an overview of the energy-resilient building concept. The review shows that most of the relevant focus is on short-term energy resilience, and the serious gap is related to long-term resilience in the context of cold regions. The article presents a basic definition of energy resilience of buildings, a systematic framework, and indicators for analyzing the energy resilience of buildings. Terms such as active and passive habitability, survivability, and adaptive habitable conditions are defined. The energy resilience indicators are applied on two simulated Finnish case studies, an old building and a new building. By systematic analysis, using the defined indicators and thresholds, the energy resilience performance of the buildings is calculated and compared. Depending on the type of the building, the results show that the robustness period is 11 h and 26 h for the old building and the new building, respectively. The old building failed to provide the habitability conditions. The impact of the event is 8.9 °C, minimum performance (Pmin) is 12.54 °C, and degree of disruption (DoD) is 0.300 for the old building. The speed of collapse (SoC) is 3.75 °C/h, and the speed of recovery (SoR) is 0.64 °C/h. On the other hand, the new building performed better such that the impact of the event is 4 °C, Pmin is 17.5 °C, and DoD is 0.138. The SoC is slow 3.2 °C/h and SoR is fast 0.80 °C/h for the new building. The results provide a pathway for improvements for long-term energy resilience. In conclusion, this work supports society and policy-makers to build a sustainable and resilient society. Full article

The construction industry in New Zealand is significantly impacted by the importance of housing, particularly as urbanisation continues to grow in major cities. Modern construction methods, such as offsite construction and building automation, evolving into digital manufacturing and construction in the industry, have become prominent. Despite the global recognition of 3D printing technology, its adoption in the construction industry in New Zealand is still relatively limited. This study aims to examine the feasibility of 3D printing construction in response to current market challenges, innovation, and the 2050 net-zero carbon goal. Utilising Building Information Modelling (BIM) and Life Cycle Assessment (LCA) approaches, this study investigated the environmental impacts of three housing types: 3D printing (3DP), light steel framed (LSF), and timber. This study used cradle-to-cradle as the system boundary. The results indicate that the 3DP house emits 20% fewer carbon emissions than the traditional timber house and 25% less than the LSF house. Additionally, the 3DP house exhibits a 19% lower annual electric energy consumption than the timber house. Therefore, in response to the growing housing demand in New Zealand, the construction industry must innovate and embrace digital and advanced construction methods, including the adoption of 3D printing.

Despite numerous concerns about climate change and the deterioration of nature, the construction industry is still one of the largest consumers of minerals and natural resources. In recent decades, sustainable construction using renewable and recyclable materials, reducing energy, and the adoption of more green technologies with the aim of reducing harmful impacts on the environment have received profound worldwide attention. The more key stakeholders involved strive to achieve sustainability, the more barriers they may face, which requires investigating them to have an effective plan to recognize, prevent, and control them. This paper reviews, classifies, and analyzes the major barriers of sustainable construction between January 2000 and April 2023. In this scientometric study, 153 articles were selected from the Web of Science database. Then, bibliometrics, the creation of maps from network data, as well as the illustration and exploration of those maps were conducted with the HistCite 12.03.1 and VOSviewer 1.6.20 software programs. The analytical results showed that the most profound barriers of sustainable construction are classified into 12 groups: price, economic parameters, awareness, technical, policy and regulations, design, management and government, environmental, social, materials, planning, and market.

The application of geopolymers has recently been given significant attention to address climate change and the growing scarcity of construction materials in the 21st century. Researchers have utilized industrial waste or supplementary cementitious materials containing high levels of silica and alumina as precursors along with different alkaline activators. Furthermore, the technical challenges associated with waste brick management or recycling include both land use changes and financial implications. The existence of amorphous aluminosilicates in waste clay bricks, which can be used as geopolymer binders, has drawn attention recently. This paper reviews the recent advancements of the integration of clay brick wastes in geopolymer applications, individually as well as its use with other alternative materials. Prior studies suggest that waste clay bricks can effectively serve as the primary source material in geopolymer applications. This review covers various aspects, including the assessment of fresh, mechanical, microstructure, and durability-related properties. It specifically focused on enhancing these properties of waste clay bricks through mechanical and thermal treatments, through varying curing conditions, utilizing different types of alkaline activators, and considering their properties and corresponding ratios in the development of geopolymer products using waste brick powder. Furthermore, this paper portrays a critical review of the sustainability implications of the utilization of clay brick waste in geopolymer applications. Conclusively, this review provided the lessons learnt, research gaps, and the future direction for investigation into the feasibility of geopolymers derived from waste clay brick powder. Full article
