In artificial intelligence (AI), generative systems, most notably Midjourney, have tremendous power to generate creative images of buildings and sites of Islamic architectural heritage through text-to-image generation based on the internet. The AI-generated representations have significant potential for architects, specialists, and everyday users. However, the system has considerable limitations when generating images for some buildings and sites where the representations appear too far from their original represented structures. Evaluating Midjourney as an architectural virtual lab, this research article attempts to define the major current limitations of using Midjourney’s AI system in producing images similar to the actual buildings and sites of Islamic architectural heritage. This research employs prompt engineering techniques based on historical sources as inputs to examine the accuracy of the output of the AI-generated images of selected examples of structures of the Islamic tradition. To validate the research results, it compares the Midjourney output with the original look by employing direct observation through critical analysis of human intelligence (HI) facilitated by the analysis of the latest version of 3M Visual Attention Software and an online survey. It concludes that while Midjourney can represent high-end AI-generated images inspired by the Islamic tradition, it currently falls short of presenting the actual appearance of some of its original structures. Furthermore, it categorizes these limitations into four groups: (1) limits of the prompt, (2) limits of fame, (3) limits of regionality and historical styles, and (4) limits of architectural elements and details. The significance of this research lies in providing timely evaluation factors to architectural heritage practitioners and software developers. This practical article is the second in a series of two sequential articles in the Buildings journal; the first (theoretical) article introduces the concept of Artificial Intelligence Islamic Architecture (AIIA), answering the question: what is Islamic architecture in the age of artificial intelligence?

Three-dimensional printing (3DP) has been rapidly evolving to be one of the leading technology fields in the coming decades. However, as in the early years of new technologies, 3DP suffers from technical limitations and various implications. This study focuses on the applications of 3DP in the construction industry, emphasizing its environmental, financial, and social sustainability aspects. A systematic bibliographic analysis was carried out for the relevant publications which increased by 25-fold from 2014 to 2021. The 3D-printed construction projects in the United Arab Emirates (UAE) are presented to demonstrate the early 3DP technology penetration into its booming construction sector. The UAE case is of particular interest from a sustainability perspective due to the environmental footprint of the ample construction activities in the country, combined with the ambitious strategic plans to achieve sustainable development goals. This critical analysis shows that, despite the limited literature, 3DP could potentially be a sustainable alternative with up to 49% less environmental footprint and 78% more cost-effectiveness compared to conventional construction techniques. As the social sustainability aspect was the least addressed, this study discusses relevant social impact indicators and systematic assessment criteria. It is evident that 3DP is already reshaping the future of the built environment, especially in cases where 3DP is advantageous, such as customized designs, quick project delivery, and sustainability-oriented constructions.

Providing quality public housing is one of the main goals of the United Arab Emirates (UAE) government. This paper assesses the level of satisfaction with public housing offered by the UAE government to its citizens based on the physical characteristics and traditional social aspects of the housing unit, urban design, and social environment in the residential area, whereas also their contribution to the residents' life quality under overall satisfaction with the place of living. At the same time, the study provides access to sustainability measurements applied at both the environmental and social levels within the Estidama accredited national rating system. The survey results of two residential complexes in Abu Dhabi show that the majority of residents are mostly satisfied, although the overall level of satisfaction with the functionality of the building and public facilities provided was generally higher than that related to the social environment in the residential district. The research focused on the application of new technologies that increase the level of sustainability in future housing projects.

Over the past 40 years, global plastic production has increased twenty-fold, prompting efforts to mitigate plastic waste. Recycling has emerged as the predominant strategy for sustainable plastic waste management. As additive manufacturing (AM) continues to evolve, integrating recycled plastics with various additives has gained significant attention. This systematic literature review, conducted in full accordance with the PRISMA guidelines, aims to evaluate and compare the properties and effects of recycled plastics and their additives in AM. Specifically, it examines the thermal, mechanical, and rheological properties of these materials, along with their life cycle environmental and economic implications. A total of 88 research publications, spanning from 2013 to 2023, were analyzed. The databases searched include Scopus, Web of Science, ProQuest, and Google Scholar, with the final search conducted in December 2023. Studies were selected through a four-stage process—identification, screening, eligibility, and inclusion—based on predefined inclusion and exclusion criteria. The risk of bias was assessed using five criteria: credibility, scope, clarity, methodology, and analysis quality. The results show that most research focuses on the mechanical properties of recycled plastics, with significant gaps in understanding their thermal and rheological properties. Additionally, there is limited research on the environmental and economic viability of these materials, highlighting the need for integrated life cycle assessments and eco-efficiency analyses. This review offers additive manufacturing professionals a comprehensive understanding of the thermal, mechanical, and rheological performance of recycled plastics and additives, supporting efforts to improve sustainability in the industry.

Courtyards are traditionally associated with the Middle East countries, where climate and culture have given shape to a particular type of traditional architecture. The study evaluates the environmental and social impacts of courtyards in an educational building integrated with occupant’s interaction behavior. The case study of the University of Sharjah includes eight different courtyards unoccupied for many years, in different locations around the building with various proportions; the objectives were to examine and evaluate the impact of redesigning the interior spaces of the courtyards in terms of environmental and social aspects. The inductive and experimental approach were adopted in this research, where two surveys were conducted for the occupants, before and after the design applications. In addition to the use of eco-tech software for simulation. In conclusion, the results of surveys and interviews clarified the problem and offered some recommendations and simulation analysis provided recommendations and guidelines for designers.

The rapid deterioration of ecosystems and the growing impacts of climate change, which is expected to increase the average global temperature by 3–6 degrees Celsius by 2100 according to The Paris Agreement, reveals that sustainability is no longer an adequate solution to these ongoing challenges. As a result, a paradigm shift toward a more evolutionary approach has recently become a demand, where regenerative concepts have rapidly replaced current sustainable practices. Rather than minimizing human impacts on the environment, regenerative ideation aims to generate more than consume and tackles many shortcomings of conventional sustainability. Therefore, the study attempts to provide an answer for the debate on how far can regenerative ideation go beyond current sustainability, and to what extent does this concept deliver on the UN’s Sustainable Development Goals (SDGs). Therefore, the study aims first to develop regenerative development goals that adopt an integrated approach and secondly to assure their compliance with the UN’s SDGs. The study employed a qualitative methodology and the case study approach to examine the applicability of the proposed principles. The findings provide clear criteria for architects and urban designers to use in spreading regenerative design to create a more responsible built environment. The study recommends further research on creating regenerative development and design metrics and indicators for practicing the concept within the built environment.
