Reviewing and Integrating AEC Practices into Industry 6.0: Strategies for Smart and Sustainable Future-Built Environments

1. An Introduction to Thematic Area Interaction: The AEC Framework in the Context of Industry 6.0

The AEC Industry 6.0 is the sixth transformative phase of the architectural, engineering, and construction sector, built on Industry 5.0 [1]. Industry 6.0 pioneers quantum computing, nanotechnology, artificial intelligence, and cloud computing energy. Harmonization facilitates design, building, and maintenance processes, improving efficiency, accuracy, and sustainability. Construction has changed, like the 5.0 framework. Industry 5.0 uses AI and robotics to boost productivity, creativity, and supply chain alignment. Even though Industry 5.0 is still developing, this alignment created Supply Chain 5.0 [2,3]. This hybrid approach allows architects and engineers to pioneer sustainable structures and shape future environments. The 5.0 project management strategy uses cutting-edge tools and technology for real-time monitoring and data-driven decision-making. Smart sensors at building sites can track progress, resource use, and site safety [4]. AI-driven algorithms can identify operational bottlenecks, optimize processes, and improve project effectiveness [5]. Analytical insights enable Project managers to prevent problems and meet deadlines [6]. Industry 6.0 is on the horizon as Industry 5.0 approaches. Industry 6.0 principles influence building design and management. A vast network of interconnected devices and sensors is needed to deify innovative structures [7], allowing them to autonomously manage and improve their functions. AI, robotics, and IoT will shape Industry 6.0. These technologies will improve intelligent infrastructures. Augmented intelligence (AuI) was born when AI and HI merged before Industry 5.0 [8,9]. AI, robots, and IoT in smart buildings define Industry 6.0. Intelligent, green, and efficient infrastructures improve comfort, efficiency, and productivity. Construction 5.0, Operator 5.0, Society 5.0, human-centricity, sustainability, and resilience are incorporated into Industry 6.0. Industry 6.0 introduces interconnected and intelligently created settings by combining human abilities with technical marvels [10]. Human labor and AI-infused technology in Industry 5.0's intelligent building context improve design, construction, and management.

AEC Industry 6.0 emphasizes productivity using AI. AI systems produce design options from massive databases of environmental variables, human needs, and building performance indicators. These options can meet energy efficiency, structural soundness, and aesthetic standards [11,12]. The generative design allows infinite possibilities in Industry 6.0. AI algorithms can produce several design iterations given parameters. These algorithms can try different combinations to find novel solutions. Deep learning improves intrusion detection systems (IDSs) [13]. Architects may refine AI-generated concepts using their experience and aesthetics to create unique and refined designs. Advanced modeling and analytical tools simulate and assess lighting, sound, and airflow in Construction 5.0 [14]. Before building, architects must consider comfort and structure. These models help evaluate energy use, environmental impact, and building longevity. AI systems recommend green improvements based on energy use and building material attributes. These insights can help architects reduce energy, carbon, and waste. Industry 6.0 promotes sustainable design with renewable energy, energy-efficient materials, and intelligent technologies. Construction 5.0 relies on VR/AR. VR gives stakeholders a tangible sense of the project [15]. AR overlays digital information in the physical world, improving real-time visualization. These technologies improve communication, design iterations, and mistake reduction [16]. Industry 6.0 promotes cross-disciplinary collaboration. AI systems let architects collaborate worldwide. A study on AI for smart building design found that accessible information and idea exchange promotes interdisciplinary collaboration [17].

The fifth industrial revolution emphasizes eco-friendly design [18]. Sustainable design requires assessing environmental statistics, energy usage trends, and material properties. When integrated throughout development, these insights enable eco-friendly infrastructures powered by renewable energy, energy-efficient materials, and smart technology. AI-enabled robots aid architecture design inventiveness, simulation, and performance optimization. These robots can quickly calculate and design solutions that meet requirements. Dialog between architects and these robots improves innovation, creativity, and efficiency. Industry 5.0's definition and scope must be clarified to grasp its technological components and basic ideas [19]. Finally, AI systems analyze building performance measurements and energy usage patterns to construct "smart" structures. Intelligent buildings use innovative technologies to enhance building operations, ensuring occupant safety and comfort [20,21]. Advanced construction robots with sensors and AI algorithms help humans accomplish tedious and dangerous tasks.

Architectural designs reflect humans' morals and stories. Alves et al. (2023) identify the Fifth Industrial Revolution as human-centered, sustainable [22]. Singh, Goyat, and Panwar (2023) said Industry 4.0 requires IoT, AI, and blockchain [23]. Industry 5.0 emphasizes human-centered construction. This trend prioritizes construction services and HR technology [24]. Kim (2022) advances sustainable building energy technologies [25]. AEC-FM's future depends on BIM-FM data exchange and Digital Twin technologies [26,27]. AI and IoT in construction improve stakeholder collaboration in Industry 5.0. Ikudayisi, Ayodele Emmanuel, et al. (2023) emphasize holistic building [28]. Digital (2021) notes that digital technology increases AEC visualization and sustainability [29]. This article reviews AEC Industry 6.0's disruptive effects on sustainable development. It will examine how digital technology, quantum theories, and advanced manufacturing affect AEC industry practices and professional culture. Sustainability, integrated tech uptake, and human-centric paradigms will guide the AEC 6.0 trajectory. Quantum radar systems, cloud-based BIM, and tech-human creativity are assessed. AEC's future should combine technical innovation with human ingenuity for optimal performance and sustainability.

2. Review of Industry 6.0 Perspectives and Their Implementation in AEC Sector

2.1. Industry and society 1.0-6.0 in the context of development

• Society 1.0 – 6.0 Evolutions

Technology has transformed civilization from 1.0 to 5.0. Each culture is briefly discussed. Society 1.0—the first human civilization—had rural settlements and pre-industrialization. Since the Internet's invention, technology has improved dramatically. [30]. Physical labor powered the economy without technology or communication. Agriculture fuelled the economy, and longstanding norms stratified and governed society. Society 2.0 began with industrialized mass production [31]. Industrialization and mechanization transformed agriculture, manufacturing, transportation, and urbanization, creating Society 2.0. Society 3.0 and Industry 3.0 and 4.0 ushered in the digital age with the widespread use of computers, the Internet, and related technology. This study investigates digital technologies that are changing society. [32]. In Society 3.0, ICT has helped firms go digital, internet commerce grows, and social media explode. Information and communication have democratized the game. Public sector organizations must provide critical services and leverage cutting-edge techniques like artificial intelligence analytics that other industries have adopted [33]. They imagine Society 5.0. Technology and economic success remedy social issues in its compassionate world. AI, IoT, and robotics will help Society 5.0 address aging populations, environmental sustainability, healthcare, transportation, and more. Technology can also improve society. Society 6.0 envisions a future where digital and real-world solutions balance economic growth and social challenges [34].

• Industry 1.0–6.0 of the Industrial Revolution

Over three centuries, new technology and industrial methods were introduced in five phases, starting in the 18th century. Steam-powered machinery began making items around 1780, according to Dixit and Uday Shanker (2023). Crafting and homesteading became common during this critical historical time [35]. Factory systems originated alongside the First Industrial Revolution. The Second Industrial Revolution introduced mass manufacturing and scientific administration to industry. CNC machinery and robotics enabled industry automation during the Third Industrial Revolution. Finally, Industry 4.0—the Fourth Industrial Revolution—incorporates computer science and information technology into production. Long-term sustainability is also emphasized. Digital manufacturing, additive manufacturing, and cyber-physical systems promise to improve connectivity and communication while simplifying data to optimize products and processes, so many developed countries have invested heavily in intelligent manufacturing technologies [36]. Due to this change, more people are working remotely. Thus, industrial equipment can help individuals return to nature. Industry 5.0 promotes human-machine cooperation. Personalization and collaborative robotics have allowed professionals to focus on consumer value rather than human needs and technology. The cyclical nature of industrial revolutions and altering manufacturing paradigms show that this dynamic has evolved. Technology changed relationships [37]. Industry 6.0 is a paradigm shift based on quantum breakthroughs, advanced biotechnologies, neural integration, decentralized autonomous systems, and a strong focus on sustainable production [38]. Figure 2 shows that this current iteration emphasizes resilience, human-centeredness, sustainability, and manufacturing methods.

2.2. Benefits of AEC Industry 6.0 in Architecture and Construction

Industry 6.0 makes design and construction more connected and promotes dynamic industry networks. It encourages flexible supply chains, adaptable value networks, and unprecedented global information interchange [39]. AEC Industry 6.0 emphasizes creating a learning and equilibrium-oriented environment. Physical and virtual architectural and infrastructure aspects inspire a new approach to integrated project delivery [40]. Stakeholders can see and evaluate physical structures and virtual data to improve global cooperation, technical assistance, and decision-making. In AEC Industry 6.0, antifragile design emphasizes flexibility and robustness. Unlike conventional buildings, this forward-thinking sector encourages a resilient system design that can resist and profit from shocks. Industry 6.0 considers functional and non-functional needs for architectural and construction systems, including openness, usability, security, and mobility [41]. These barriers now aid sophisticated projects. AEC Industry 6.0 should stimulate design and construction innovation. Human abilities and cutting-edge technology will make built settings more sustainable, effective, and beautiful [42]. These revolutionary methods will elevate architectural design and construction, enhancing human and environmental well-being.

2.3. Additive manufacturing (3D printing)

Production, distribution, and use processes are dramatically changing thanks to additive manufacturing (AM) technology, particularly in the architectural, engineering, and construction (AEC) industry [43]. This ground-breaking paradigm change, including a broad range of technologies, significantly impacts the production and use of a wide range of goods and parts. According to S. Salinas Monroy, P. Li, Y. Fang, and K. A. Polarities, this revolutionary movement created consumer goods and radically altered the architectural design field and the building sector. The core of the AM paradigm, 3D printing, uses a methodical process of successive layer-by-layer material deposition. This method of operation significantly lowers marginal manufacturing costs and promotes dramatic industrial supply chain simplification. [44]. One notable benefit of additive manufacturing (AM) in the architecture, engineering, and construction (AEC) industry is its capacity to facilitate localized production [45]. The proximity of manufacturing facilities to customers can significantly alter the supply chain dynamics, improving efficiency and flexibility. Furthermore, additive manufacturing (AM) technology enables production with reduced considerably marginal costs and offers a potential pathway for enhanced economic efficiency in manufacturing and building procedures (see Figure 3).

3D printing, or additive manufacturing, is changing the AEC industry. 3D printing provides customization and accuracy for making intricate I panels, fittings, and other aesthetic features [46]. This technique improves building aesthetics and function. Several companies 3D print whole buildings. Industrial-scale printers with fast-hardening concrete save construction time, cost, and environmental impact. Apis Cor offers 24-hour home printing. Urban planners also utilize 3D printing to swiftly produce and change scale models of cityscapes [47]. As 3D printing in building advances, we expect more inventive uses.

2.4. Artificial intelligence and autonomous robots

The harmonious marriage of Artificial Intelligence and autonomous robotics fundamentally redefines AEC Industry 6.0, spearheading an organizational and operational transformation [48]. These ingenious robotic systems can tackle complex tasks, heightening efficiency, bolstering safety, and streamlining cost-effectiveness. Utilizing Machine Learning algorithms, they autonomously adapt, learn, and perfect processes. Experts Mohsen Soori, Behrooz Arezoo, and Roza Dastres point out that AI, ML, and DL have breathed new life into sophisticated robots, increasing their intelligence, efficiency, and adaptability. Advanced robotics leverage these technologies for autonomous navigation, object recognition and manipulation, natural language processing, and predictive maintenance. Additionally, they facilitate the creation of collaborative robots, or ‘cobots,’ that seamlessly interact with humans in dynamic environments and tasks.[49].

Figure 4. Artificial intelligence within autonomous robots’ interaction.

Figure 4. Artificial intelligence within autonomous robots’ interaction.

The applications include a broad spectrum, spanning from using artificial intelligence to anticipate equipment failures in the context of predictive maintenance to the execution of precise tasks by robots in advanced manufacturing. The importance of human-robot cooperation is also underscored, with robots being used to aid human employees rather than replace them [50]. The objective of AEC Industry 6.0 is to provide a more customized, environmentally conscious, and comprehensive industrial setting by integrating human creativity with artificial intelligence capabilities [51].

2.5. Optimizing AEC Industry with Cyber-Physical Systems and Smart Factory Simulations

AEC is being transformed by Cyber-Physical Systems (CPS), simulation technologies, and intelligent manufacturing facilities. The changes above affect architecture, construction, and maintenance. According to experts like Tran Duong Nguyen and Sanjeev Adhikari, the building sector needs help to integrate digital and physical domains. Data analysis and action must be separated. This gap causes data fragmentation, duplication, and construction life cycle inefficiency. [52]. Cyber-Physical Systems (CPS) use computer, networking, and physical processes to detect structural faults and enable predictive maintenance. Building Information Modeling (BIM) is a leading simulation technology that lets stakeholders create sophisticated three-dimensional models to simulate the complete lifecycle of a built environment. Doukari, Omar, Mohamad Kassem, and David Greenwood explain that Building Information Modelling (BIM) has evolved from a computer-assisted tri-dimensional modeling tool to include chronological scheduling, fiscal oversight, and an information management structure that can improve decision-making across the entire life cycle of constructed assets. Building Information Modeling (BIM) is a vital simulation technology tool that allows stakeholders to create sophisticated three-dimensional models and simulate a built environment's lifespan. According to Doukari, Omar, Mohamad Kassem, and David Greenwood, BIM evolved from a computer-aided tri-dimensional modeling tool to include chronological scheduling, financial oversight, and an information maze. This technique optimizes performance and predicts potential problems. Intelligent factories in the Architecture, Engineering, and Construction (AEC) industry integrate IoT, AI, and big data analytics to improve production [54]. Automated component production streamlines on-site assembly and reduces waste. These technologies enhance architectural flexibility, safety, and efficiency. Integrating Cyber-Physical Systems (CPS) with intelligent manufacturing has transformed the construction sector, encouraging equipment and supplier collaboration. Hamzah M et al. defined CPS as cyber-physical convergence. Interconnectedness allows global integration and substantially influences daily life, especially CPS implementation. This integration poses hurdles. CPS broadens perceptions and spurs innovation [55]. Digital twins improve building operations and help identify issues, while simulators provide a safe training environment.

2.6. Big Data Applications in the AEC Industry 6.0 Future

In the 6.0 era, merging Big Data technology with Internet of Things (IoT) devices provides a cutting-edge technique for managing complicated and extensive building project data. Technology integration helps create novel services for architectural, engineering, and construction (AEC) professionals and others [56]. The app improves building site analysis, decision-making, and operational efficiency. Big Data can help the AEC industry understand construction patterns, building practice trends, and project abnormalities. This can spur innovation and shape design, planning, and building processes. AEC Industry 6.0 raises work roles to improve client customization and give specialists unsurpassed creativity. Automation helps architects design for clients. AEC Industry 6.0 introduced client-focused value propositions. Real-time feedback and improved automation facilitate this shift. AEC Industry 6.0 integrates human knowledge and mechanical precision [57]. Collaboration promotes decision-making, problem-solving, design, and construction. Automated work management boosts morale by offering intellectually engaging roles, personal development, and job satisfaction. Inclusion is a goal of AEC Industry 6.0 [58]. This balances career advancement, employment, and skill development. AEC Industry 6.0 encourages green building. It enables eco-friendly buildings. Adaptation will determine AEC Industry 6.0 success. Human-focused, resilient, green firms will lead. Human-oriented designs, resilient resilience, and inclusive sustainability—the pillars of AEC Industry 6.0—need more research [22].

3. Method and materials

This study’s approach is based on a systematic literature review, as described by RAO, Purnima; a systematic literature review aims to provide new frameworks and perspectives by critically evaluating and synthesizing existing research on a particular issue. It has been determined that an integrated systematic review is the most suitable approach to handle the research issue in this study because of its emphasis on novel and developing themes and subjects. To ensure transparency and consistency, the systematic review process necessitates adherence to a clearly defined protocol or plan, wherein the criteria for study selection are explicitly stated before the review initiation [59]. According to CRONIN, Matthew A, a proficient integrative review holds significant potential for offering valuable insights into the present research landscape about a construction 5.0 topic while also providing recommendations for future research endeavors. The present article explores diverse categories of reviews and presents a systematic framework for conducting an integrative review. Moreover, it offers guidance concerning the challenges encountered during the composition of integrative studies, including the equitable presentation of diverse perspectives and the synthesis of knowledge to generate novel insights. Compared to other forms of knowledge synthesis, such as narrative reviews, systematic reviews, and meta-analyses, the distinctive value of an integrative review becomes evident [60]. Dodgson (2021) emphasizes the importance of adhering to specific criteria to ensure a systematic review’s methodological rigor. Moreover, the author asserts that literature reviews are crucial in advancing our understanding of a subject. Dodgson states that a literature review becomes particularly valuable when it contributes new insights to the existing body of knowledge. Although various methodologies exist for conducting literature reviews, there are shared elements of methodological rigor that should be upheld. In the present study, the SCOPUS database was employed as the primary search tool for the investigation, ensuring comprehensive coverage of relevant literature. The search technique looked for articles published in the “construction and industry 4.0 and 5.0 “category of more recently published articles that had the terms “Industry 4.0” or “Industry 4.0” in the title, abstract, or keywords. Similar procedures were carried out in the case of the words “Industry 5.0,” “Society 5.0,” and “Construction 5.0.” While the most current keyword resulted in no relevant articles being picked (see Table 1 for an explanation of the SCOPUS search process), the top 10 pieces for each topic were chosen. In the second phase, a supplementary search was conducted using “Google Scholar” to increase the breadth and depth of the research. This study focused on developments in the last few years and used the phrases “construction 5.0,” “Industry 4.0,” and “Industry 5.0,” either singly or in combination. Twenty more articles were chosen in this way to make up for the need for more pedagogy-focused studies in the first search (see Table xx for details on the Google Scholar search tactics employed). AL-ALAMI, Suhair argues that a critical mindset is necessary to study literature. For example, when reading literature, one must draw upon their life experiences to understand it [61].

4. Transforming Construction through Industry 6.0: Technology Integration, Sustainability, and Collaborative Innovation

4.1. Development of a Sustainable smart building Using AEC Industry 6.0 Principles

The Integrated Design Process optimizes Building Information Modeling (BIM) for stakeholder engagement in modern AEC. Digital twin technologies merge virtual and physical worlds to track construction progress [62] meticulously. Dynamic supply chain methods enable real-time tracking, fast deliveries, and enhanced efficiency. Structures can better withstand natural disasters by using Antifragile Design Principles. A net-zero energy benchmark prioritizes sustainability and resource efficiency. Human-Centric Innovation, influenced by AEC Industry 6.0, emphasizes tenant well-being and its impact on productivity. Additionally, strict security and compliance mechanisms ensure regulatory compliance. Operator 6.0 will lead the AEC industry's subsequent development with cutting-edge technology and eco-friendly practices. This groundbreaking model uses BIM principles for real-time design collaboration, precise visual representations, and early discrepancy discovery [63]. Automation and robotics transform excavation and assembly. Real-time data interpretation via the IoT boosts operational efficiency. AI and ML provide perfect design and resource allocation. Augmented and virtual reality provide deep and engaging perspectives on varied tasks. Renewable energy shows sustainability. Cloud computing provides universal data access and advanced data analytics for informed decision-making. Figure 6 depicts a revolutionary construction and architectural design era based on this comprehensive concept.

The architectural engineering business successfully developed an advanced and environmentally friendly skyscraper by using the concepts of AEC Industry 6.0. The project exemplified the potential of technology and new approaches in revolutionizing architectural engineering, creating a building that serves as a dynamic and flexible structure, serving as a monument to the industry’s future.

4.2. Revolutionizing the Construction Sector: The Integration of Industry 6.0 and Sustainable Practices

Architecture, infrastructure, and urban planning depend on construction. Industry 5.0 in building emphasizes human-robot collaboration [64]. AI, IoT, and blockchain affect industries, especially construction. Combining human and technology skills, Industry 6.0 boosts building productivity, sustainability, and creativity. Optimizing construction results [65]. AI, IoT, VR, and machine learning may transform project planning, design, and management with Industry 5.0. These innovations improve building and growth [66]. VR revolutionizes participatory design. Stakeholder participation in design and planning improves engagement and design understanding. VR lets stakeholders plan structures realistically [67]. IoT sensors improve building maintenance, enabling data-driven design and construction. Architects, engineers, and builders must collaborate in the Fifth Industrial Revolution. AEC Industry 5.0 stresses transdisciplinary collaboration. BIM promises cost-effectiveness and high-quality design [68]. Sharing datasets and digital platforms improve project outcomes. Construction Industry 6.0 emphasizes sustainable materials and efficient procedures. Robots, AI, and 3D printing boost sustainability. Cloud computing technologies are also showing promise in modest building projects [69]. Project delivery improves with Industry 6.0. It improves operations, communication, and project engagement. Advanced technology enhances business [70].

Figure 7. Synergizing the AEC components with Industry 6.0.

Figure 7. Synergizing the AEC components with Industry 6.0.

The increased usage of digital platforms and cloud-based solutions has enabled people to collaborate in real time. Data analytics and visualization tools allow project managers to keep track of work, identify issues, and make informed choices. Where Dwivedi, Yogesh K., et al. (2023) affirm that a virtual environment supported by metaverse has the potential to extend the physical world using augmented and virtual reality technologies allowing users to seamlessly interact within actual and simulated environments using avatars and holograms [71]. Furthermore, digital twins, digital representations of tangible assets, enable simulation and predictive modeling, resulting in better project planning and risk assessment. The merger of the construction sector into Industry 5.0 has the potential to transform project conception, design, construction, and management. In the study conducted by Zairul, M. and Zaremohzzabieh, Z. (2023), it is evident that waste management poses a critical challenge within the building sector due to the substantial amount of waste generated during manufacturing. Moreover, the industry must address the escalating need for sustainable construction materials to accomplish the objectives outlined in the climate agreement, emphasizing the transition toward clean energy sources [72]. Utilizing cutting-edge technology, promoting cooperation, and prioritizing sustainability may help the construction sector increase production, efficiency, and innovation. However, obstacles like data security, interoperability, and workforce upskilling must be surmounted before this integration can reach its full potential. The construction industry may usher in a new age of environmentally responsible and technologically advanced building practices by adopting Industry 5.0 with the correct strategy and investments.

4.3. Smart building within AEC industry 6.0

AEC Industry 6.0 emphasizes smart buildings with advanced technology and complex systems to enhance energy efficiency, occupant comfort, safety, and operations [73]. AEC Industry 6.0 is adaptable, collaborative, and flexible to create a positive human-technology relationship. Salem and Dragomir (2023) suggest adopting a risk treatment process and a unique risk matrix to improve risk management in building projects with digital twins. A digital risk management strategy improves predictive skills, helps human decision-makers reduce unforeseen expenses and failures, and boosts operational efficiency. More study into shared information and data protection is needed to minimize intentional and unintentional exploitation and create a fully digital system [74]. Smart structures in AEC Industry 6.0 use IoT devices and sensors. These high-tech buildings analyze data using data analytics and machine learning. Krishnan P. et al. (2023) suggest recognizing abnormal energy consumption to conserve energy. Smart buildings can provide a more sustainable, eco-friendly environment that supports residents' different lives by using this strategy. Optimizing energy efficiency in lights, HVAC controls, energy monitoring, building envelope, automation systems, and renewable energy sources yields IoT device parameters. Algorithms and parameters from water, network convergence, electrical, and environmental monitoring boost energy efficiency [75]. The algorithms above enable pattern detection, trend prediction, and operational improvement. Predictive maintenance algorithms evaluate equipment sensor data to detect abnormalities and future concerns, reducing downtime. IoT and wearable technologies in intelligent buildings monitor user preferences and alter ambient variables for comfort. Sustainable renovation improves energy efficiency, building value, indoor and outdoor convenience, carbon emissions, and occupant satisfaction and well-being, according to Velykorusova (2023). [76]. Climate, lighting, and ergonomics boost productivity and satisfaction. Smart buildings monitor air quality and noise in real-time, creating healthier and more comfortable workplaces. Smart buildings have improved surveillance, access control, and emergency response systems. BIONDO, Elias Junior (2023) states that people spend 90% of their time indoors, where air pollutants like carbon monoxide (CO), carbon dioxide (CO2), volatile organic compounds (VOCs), sulfur dioxide (SO2), ozone (O3), and nitrogen oxides (Nox) can be two to five times higher than outdoor levels and sometimes 100 times higher.[77]. Video analytics, face recognition, and access controls identify security risks. Intelligent structures can initiate evacuations, guide residents to safety, and notify emergency services. Construction 5.0 smart buildings communicate with intelligent city infrastructure to share waste, electricity, and transportation data. This enhances resource allocation, sustainability, and environmental impact. Digital Twin (DT) technologies create a virtual system version to monitor system operations, connections, and interactions, according to UTKU, Durdu Hakan et al. (2023). Thus, fresh technical approaches and concepts are being researched to optimize building processes by maximizing restricted resources [78].

Innovative building Building administration Systems (BMS) can simplify asset, facility, and energy management. Remote monitoring and control let facility managers identify maintenance issues, improve building performance, and fix problems [79]. Data analytics, current technology, and sustainability enhance operational efficiency, occupant comfort, safety, and energy saving in 5.0 smart buildings. Connectivity, automation, and sustainability define intelligent industrial infrastructure and human-machine collaboration. Smart building technologies (SBTs) offer energy efficiency, cost-effective maintenance and operation, employment opportunities, healthcare management, real-time monitoring, and improved safety and security, according to EJIDIKE, Cyril Chinonso; MEWOMO, Modupe Cecilia (2023). Understanding smart building technology's benefits is essential in developing economies. Building experts' awareness will help these regions implement and adopt [80]. Smart buildings increase comfort, energy efficiency, and operations.

I.

Automated systems: Intelligent systems and sensors optimize energy consumption in smart buildings. Real-time data, occupancy patterns, and ambient conditions optimize lighting, HVAC, and other energy-intensive equipment [81].

II.

Dynamic controls: Smart buildings adapt to occupant preferences and time of day. This personalized strategy saves money by turning off lights and thermostats in empty rooms [82].

III.

Data analytics and machine learning algorithms optimize power usage. These findings help facility managers manage energy and cost savings [83].

4.4. Comfort in intelligent living spaces

Intelligent buildings allow workers to customize lighting, temperature, and other characteristics for comfort [84]. According to Majid Al Mughairi, Thomas Beach, and Yacine Rezgui, building automation systems are their brains. These advanced systems control HVAC, lighting, security, access control, surveillance, and indoor air quality. These systems collect data and execute commands via a gateway using strategically placed sensors and actuators in the building. This creates a dynamic, energy-efficient living space. These management systems balance technology and comfort by responding to occupants' unpredictable behavior [85]. This personalized approach enhances convenience, comfort, and efficacy, as thermal conditions affect thermal contentment and productivity in built environments. Bueno, A.M., de Paula Xavier, A.A., and Broday, E.E. noted that academic research had illuminated thermal comfort and productivity throughout history. Mathematical models predict productivity changes by analyzing ambient temperature variations due to the necessity to understand how environmental variables affect performance, especially considering how much time people spend indoors; multiple models have failed. Buildings must prioritize comfort, energy efficiency, and sustainability [86]. IoT technology allows real-time air quality, noise, and other environmental monitoring, making the environment safer and more pleasant. Kureshi, R.R.; Thakker, D.; Mishra, B.K.; Barnes, J. state that indoor and outdoor air quality is a human right. Despite its health risks, interior air pollution has gotten less attention than ambient pollution from healthcare institutions, communities, and local authorities. Methodological case studies on indoor air pollution's sources and effects are urgently needed due to the amount of time people spend indoors and its negative impacts, especially on those with respiratory and other health issues. These studies should also examine ways to modify indoor activities that cause indoor air pollution and respiratory problems. [87]. IoT devices and sensors enable real-time air quality, noise, and environmental monitoring. Thus, informing building users of concerns may improve safety and comfort.

Smart Building Adaptive Systems: These buildings can automatically adjust lighting, temperature, and other systems based on occupancy. No human interaction is needed because the system is adaptive, ensuring comfort. Gholamzadehmir, Maryam, and others have popularized intelligent architecture and socially resilient cities. Building automation systems help control energy generation, use, and storage. Building automation and control systems use old and innovative control approaches. Intelligent buildings require advanced solutions [88]. Smart buildings employ building management systems (BMS) to monitor and regulate multiple building processes, improving efficiency. Lam, K.H., To, W.M., and Lee, P.K.C. found that intelligent buildings can minimize energy use and provide a responsive, pleasant, and productive interior environment. Smart buildings require an intelligent building management system (SBMS). An SBMS must execute many tasks and give the expected benefits [89].

Automated lighting controls and resource allocation in intelligent buildings improve process efficiency. Shah, S.F.A., et al. showed that computerized methods could expedite labor processes, reduce human intervention, and boost productivity [90,91]. Machine learning can automate many processes using intelligent, developing algorithms. Smart Buildings, an IoT application, is notable. These structures provide an efficient and convenient ecology through integrated operations. Baduge, Shanaka Kristombu, and their colleagues recently expanded this notion. They examine how the construction sector is adopting Digital Twin (DT), Building Information Modelling (BIM), AI, IoTs, and Smart Vision (SV). These current building and construction technologies combine efficiency, productivity, accuracy, and safety [92]. Advanced production systems, cyber-physical methodologies, and digital technology alter the building and infrastructure; Barnesre lifecycle from design to maintenance in AEC Industry 4.0. Key elements: According to Majid Al Mughairi, Thomas Beach, and Yacine Rezgui, building automation systems are their brains. Key elements include:

• Production Systems: 3D printing, prefabrication, and offsite manufacturing.
• Cyber-Physical Tools: IoT, robotics, and actuators.
• Computing Technologies: BIM, AI, ML, cloud computing, data analytics, Blockchain, AR, and digital twins.

Such integration fosters enhanced industrial capabilities, streamlining and intelligently managing facets like temperature, safety, and maintenance via mobile devices and computers. With the rise of IoT, intelligent buildings have become central to system integrations. Advanced HVAC controls reduce peak energy demand, optimizing energy and promoting sustainable practices. [90].

Smart buildings represent a significant advancement in sustainable and efficient industrial infrastructure, as they play a crucial role in enhancing energy efficiency, occupant well-being, and operational processes. By integrating cutting-edge technologies and intelligent systems, these buildings are designed to minimize energy consumption while optimizing various aspects of occupant comfort and productivity. Incorporating innovative technologies in building systems enables precise control and monitoring of energy usage, reducing energy consumption and lowering greenhouse gas emissions. By leveraging advanced sensors, data analytics, and automation, smart buildings can adapt their operations based on real-time conditions and occupant behavior, thus maximizing energy efficiency and minimizing waste. Moreover, the emphasis on occupant well-being is a cornerstone of smart building design. These buildings are equipped with features that enhance indoor air quality, regulate lighting levels, and maintain comfortable temperatures, all of which contribute to a healthier and more conducive environment for occupants. Studies have shown that such improvements in indoor environmental quality can lead to increased productivity, reduced absenteeism, and enhanced occupants’ overall well-being [93]. Additionally, smart buildings streamline various operational procedures by seamlessly integrating different systems, enabling centralized monitoring and control. This integration allows for data-driven decision-making, predictive maintenance, and optimized resource allocation. As a result, processes within the building are more efficient, responsive, and cost-effective, leading to a more sustainable and productive overall industrial infrastructure [94].

4.5. Sustainable Development in the AEC Industry Area

In recent years, sustainable development has grown significantly in the AEC industry [95]. A balanced approach is essential to meet current needs without jeopardizing future generations, encompassing economic growth, environmental protection, and social welfare. In the Architecture, Engineering, and Construction (AEC) sectors, “sustainable development” means employing eco-friendly techniques, promoting energy efficiency, minimizing waste, and optimizing asset performance and longevity. Schutzenhofer et al. note that the AEC sectors account for 40-60% of global raw material extraction. For continuous circular economic model implementation, it’s vital to consider material, emissions, and energy. This study delves into disassembly, recovery, and recycling processes, evaluating technical efforts and costs against potential eco-impact. [96]. As a result of the substantial environmental effect of building operations, the AEC sector has realized the urgent need to implement sustainable practices. The world's buildings and infrastructure significantly impact energy, greenhouse gas emissions, and resource depletion.

MEC provides real-time, low-latency, and high-bandwidth access to radio network resources when integrated with 5G systems, enabling network operators to deliver new services and create a unique ecosystem and value chain. The Internet of Things (IoT) is a complex ecosystem of different, resource-limited physical things, according to Liyanage, Madhusanka, et al. IoT has applications in healthcare, agriculture, smart cities, automotive, and industry [103]. IoT applications require centralized cloud computing for data processing and storage. IoT devices have resource constraints, including low battery power, memory, and computing. IoT must also enable real-time, scalable apps with low latency and excellent QoE as needed. Thus, IoT applications must meet performance and efficiency requirements [104]. Logic Controllers Uncrewed aerial vehicles, autonomous ground vehicles, and robots may change production. Infrastructure, safety, and autonomy are studied like Quantum Computing. Quantum computing may enable complicated problem-solving, system modeling, and industrial process optimization. Industrial quantum computing research is possible. Construction 6.0 may involve green production, renewable energy, and energy-efficient technologies. This research may be green manufacturing [105]. Self-driving automobiles, uncrewed aerial vehicles, and robots are projected to change industrial operations even further shortly. To maximize these technologies' potential, researchers will focus on critical areas.

• Advanced Autonomy and Decision-Making: This research seeks to produce advanced autonomous systems that can make real-time decisions in complex and changing operational settings. Complex algorithms and advanced machine-learning models are needed for meaningful autonomy. Algorithms have long existed. Their rising use in decision-making systems warrants notice. Algorithmic Decision Systems (ADS) analyze personal data to find correlations and extract decision-making information [106]. In fully automated ADS, human involvement in decision-making may be absent. These choices affect people's credit, career prospects, medical care, and legal fines, highlighting the study's importance and complexity.

• Autonomous systems must prioritize safety and security. This study examines risk reduction, fail-safe measures, and building control systems cyber-security. According to Illiashenko et al., security-informed safety (SIS) or cybersecurity-informed safety (CSIS) is a developing interest in assessing autonomous system safety and reliability using an entropy-oriented technique. [107].

• Autonomous Systems and Infrastructure Integration: Integrating autonomous systems into existing infrastructures and conceptualizing and developing new infrastructures to support them has become a significant area of research. This includes creating communication protocols, optimizing information transfer, and adapting the architectural design for emerging technology. Yogesh K. et al. have proposed that the metaverse could expand the physical realm using augmented and virtual reality technologies. Avatars and holograms may enable seamless interaction between real and virtual surroundings. However, the technology and infrastructure needed to create massive, immersive virtual worlds that allow avatars to span platforms are still in development. Despite this constraint, scholarly research into the metaverse's potential to revolutionize society and human interaction is rising, suggesting a promising route for future research and innovation [108].

• Accelerating AEC Materials Discovery and Design Quantum Computing: Quantum computing may solve complicated problems that regular computers cannot. Quantum algorithms and frameworks for AEC procedures are being studied. Supply chain optimization and advanced materials research use material passports. Quantum computing emphasizes materials science. Yue Liu et al. says contemporary research screens innovative materials with increased performance and models quantitative structure-activity relationships. These efforts represent a new frontier in materials research, where experimental studies and computational modeling are time-consuming, resource-intensive, and limited by experimental conditions and theoretical foundations. Accelerating materials discovery and design requires a paradigm shift, including computational research and experiments. Thus, material features can be better understood, enabling more efficient and focused research into novel materials. This integrated strategy may disclose key material behavior regulators, enabling more effective and purpose-driven materials discovery and design [109]. Quantum computing and AEC manufacturing may change materials science. Quantum algorithms can overcome computational limits and speed up materials research. An integrated framework that links computers and experimentation aims to develop a future with unique materials that can alter many sectors and expand human ingenuity.

• Renewable Energy Integration: AEC Industry 6.0 investigates renewable energy integration into industrial processes and supply networks. Examples include optimizing energy storage systems, developing new grid technologies, and improving industrial energy efficiency. Worku (Y) reports a rise in greenhouse gas reduction and electric energy dependability measures. Over the last decade, intermittent renewable energy sources (RESs), including photovoltaic (PV) and wind, have been added to the power system. However, operational and control difficulties make renewable energy integration difficult for the power system. Generation uncertainty, voltage and angular stability, power quality, reactive power assistance, and fault ride-through are blocks [110]. However, research will advance energy-efficient design and construction methods. Energy and waste reduction can lessen AEC businesses' environmental impact.

• Sustainable manufacturing will spur research on eco-friendly materials and techniques [111]. Engineers and scientists will focus on biodegradable materials; circular economy approaches, and low-impact production [112]. Kazakova and Lee explain that the circular economy paradigm and changing consumption patterns force the Architecture, Engineering, and Construction (AEC) industry to embrace more sustainable design and operations. In this setting, customers and investors pay attention to firms' environmental, economic, and social behaviors. Over 20% of worldwide greenhouse gas emissions come from manufacturing. In a UN Environment Programme assessment, the production and consuming phases of the industrial cycle are highlighted as harmful. Toxic gases, acidic compounds, and unsustainable depletion of non-renewable resources worsen environmental stress [113] (see Figure 8)

Researchers grapple with transdisciplinary challenges as technology progresses, striving to make industrial processes autonomous, efficient, and sustainable [114]. Technology's societal and ethical implications are pressing; hence, its use must ensure minimized harm and disparity as industries evolve. Crucial issues include data privacy, security, and individual rights. Technological advancements often surpass existing regulations, leading to potential pitfalls. A harmonized international legal framework, adaptive to technological changes, is imperative for safe and ethical technical integration [115]. The environmental challenges presented by technology-centric industries necessitate an urgent focus on reducing ecological footprints, promoting sustainable practices, and advancing renewable energy research. Simultaneously, data-driven businesses highlight the need for robust encryption, secure data exchange, and technologies that prioritize user privacy. A balance between automation and human collaboration, supported by user-friendly interfaces and continued workforce training, is crucial for societal advancement [116]. Multidisciplinary research holds the key to addressing these multifaceted challenges. Collaboration across disciplines fosters innovation and the development of green technologies, promoting sustainable practices and the circular economy and reducing environmental impacts [117]. Technologies such as automation, AI, and data analytics optimize processes, conserving resources while boosting productivity. Tackling global challenges demands international interdisciplinary cooperation in sharing knowledge and resources. Multidisciplinary research stands poised to harness technology and learning, addressing concerns like ethics, legal frameworks, sustainability, data privacy, and human-machine collaboration with a holistic approach. Embracing these opportunities and challenges can usher in an era of innovation and heightened environmental consciousness (See Figure 9).

5.2. The Human at the Center of AEC Industry 5.0: An Approach to Society

The recent shift in organizational function has prominently featured human-centric methodologies, marking a change in the dominant paradigm.

AEC Industry 5.0 places humans at the center of these technological changes, utilizing technology to promote human well-being, social inclusion, and sustainable development [119]. It envisions a society where humans and robots collaborate for a brighter future.

Grabowska, S., Saniuk, S., & Gajdzik, B. have pointed to the heightened scientific interest in industrial humanization, sustainability, and resilience, due to the pervasive digitization and advancement of fourth-industrial revolution technologies [119]. Industry 4.0 focuses on cyber-physical systems within organizations and their supply chains, while AEC Industry 6.0 emphasizes people's unique attributes and talents beyond robotic capabilities. The core objective is to leverage technology to enhance human abilities, granting them more autonomy.

As highlighted by Wang, Baicun, et al., human-centricity remains pivotal to Industry 5.0, underscoring the importance of human needs ranging from health and safety to self-actualization and personal growth [120]. The Human Digital Twin (HDT) concept is fundamental in achieving this focus within intelligent manufacturing systems. HDTs provide digital representations of humans, revolutionizing human-system integration by incorporating human characteristics into system design. A hallmark of AEC Industry 6.0 is the symbiotic relationship between humans and robots. Instead of replacing humans, the objective is to augment human capabilities, enabling them to participate in advanced decision-making, creativity, and problem-solving. This industry also champions digital access equity, aiming to equip underserved communities with modern tools and training, thus reducing biases and promoting inclusivity [121]. The potential of the metaverse, which blends physical and digital interactions, is likened to past innovations such as the internet and e-commerce, offering tools to effectively manage the transition to AEC Industry 5.0 [122]. AEC Industry 6.0 prioritizes human health and safety [123]. Utilizing technology improves working conditions, enhancing the quality of life. Repetitive or labor-intensive tasks can now be relegated to machines and automation, allowing employees to focus on more fulfilling roles [124]. The shift towards AEC Industry 6.0 represents a crucial turn in industrial evolution, merging human expertise with technological proficiency. This blend results in manufacturing solutions that are resource-efficient and valued by consumers, heralding a transformative shift in the industry [125].
