The capital of Saudi Arabia is evolving into one of the most attractive cities in the Middle East due to various ambitious expansion projects aligned with Vision 2030. This urban development strategy requires researchers to adopt evaluation approaches based on comprehensive sustainability criteria, including environmental and cultural sustainability, community involvement, and economic feasibility. This study utilizes the Delphi methodology to define evaluation criteria and their importance, employing the Delphi technique to gather insights from a group of experts through three rounds of questionnaires. The responses were analyzed using the Top-of-Priority Similarity to Ideal Solution (TOPSIS) technique to develop an integrated evaluation model, which assessed architectural practices in Riyadh through three key projects: The King Fahad National Library, Qasr Al-Hokm, and Saudi Arabia's Digital City. Data sources included extensive site visits, project documentation, and expert evaluations. The evaluation model demonstrated varying levels of sustainability across the projects. The King Fahad National Library and Qasr Al-Hokm showed high scores in sustainability practices, while Digital City lagged behind in several areas, highlighting the need for improvement. This research enhances the understanding of how globalization influences urban renewal in Riyadh and emphasizes the importance of developing effective evaluation models that address the multifaceted nature of sustainability. The findings underscore the need for continuous reassessment of architectural initiatives in the city to align with both international standards and local cultural contexts. The proposed evaluation model successfully tests sustainability frameworks at the local level, indicating areas for future enhancements and contributing valuable insights toward achieving sustainable urban development in Saudi Arabia.
1 Introduction
Urban development processes reflect the progress of social development and their impact on people’s quality of life (Chaskin and Joseph, 2011). It serves as an indicator of the overall economic performance of both developed and developing nations, making significant contributions to their GDPs. The primary products of this industry are “buildings,” which are essential to daily life (Sun et al., 2024). he rapid urban expansion seen in Riyadh offers a unique and illustrative example for exploring global urban development issues (Jarrar and Al-Homoud, 2024).
Today, contemporary architecture is confronted with the challenges of spatial globalization. In rapidly developing regions, construction processes may result in a situation where the distinctions between one place and another become irrelevant, leading to cities that are imitations of other cities. Buildings are moved from one context to another without considering their impact or adopting a sustainable approach to design (Bowring et al., 2009). A recent literature review by on “urban development” points to shifts towards sustainability adoption and an increasing focus on the urban context and examination of different dynamics in sustainability transitio (Frantzeskaki et al., 2017) Cities have increasingly been identified as particularly important places for sustainability transitions and related system innovations to emerge and unfold (Fuenfschilling et al., 2018). Sustainability assessment has been identified as one of the beneficial tools that exist and can be used in order to foster the sustainable development, ranging from the design, construction, right through to management stages (Ameen and Mourshed, 2019; Bai and Guo, 2021).
Nowadays, many countries or researchers have developed related indicator frameworks to evaluate an individual building or entire cities (Yang et al., 2015), involving Leadership in Energy and Environmental Design (LEED) from the United States (Hopkins, 2015). Exam current architectural landscape in Riyadh through the lens of globalization reveals a number of complexities. Over the past few decades, various architectural trends have emerged that, despite being labeled differently and having overlapping elements, ultimately converge toward the same goal of modernity across various domains, including architecture. In most cases, they have focused on incorporating the principles, characteristics and elements of sustainable design but have suffered from a gap in the comprehensive evaluation approach (Akadiri et al., 2012).
While the application of global technologies and sustainability practices may be entirely beneficial, the overuse of architectural materials and features that are incompatible with the local context is becoming increasingly worrisome. This is an ongoing discourse that emphasizes the balance between global influence and local reality (Sassen and Wills, 2004), thus placing at its heart the fundamental challenge of architecture is what works and what does not (Punter, 2016). Indeed, the emerging focus on global architectural trends has led critics to assert that expansionist projects such as these have grossly neglected contextual issues of a local nature. This adoption of global architectural models reflects the quest for modernity in architecture, but when replicated on a large scale in many countries, it has led to this research interest in a comprehensive understanding of the contemporary architectural landscape in Riyadh in light of globalization from a sustainable perspective (Naim, 2013).
There is a lack of research on measuring the sustainability of urban development at the community level. This is generally done in a subjective and one-sided manner when it comes to selecting and weighting indicators. Most studies on sustainability assessment take the perspective of consistency with certification bodies such as LEED or others that deal only with energy consumption, ignoring the economic and cultural dimensions of sustainability. (Ding, 2005; Dziekan, 2012).
Numerous studies (Michalina et al., 2021) argue that some community-level indicator frameworks for measuring sustainable urban devlopment, such as LEED-ND and BREEAM-Communities, also neglect to comprehensively analyze the social, economic and environmental aspects of sustainability. They exhibit ambiguity and shortcomings in weighting, scoring, or ranking systems. Furthermore, The number and type of indicators also differ significantly among these proposed indicator frameworks.
Too many indicators make data collection and assessment cumbersome (Ghosh et al., 2006), while a few indicators cannot provide full insight into any assessment. The continual conversation about the equilibrium between global influences and cultural authenticity highlights the fundamental challenge within the architectural domain of discerning what is suitable and what is not. It is crucial to acknowledge that, although there is an increasing emphasis on global architectural trends and expansion initiatives, concerns have been voiced about the oversight of local contextual matters (Mba et al., 2024; Selim, 2018). From this standpoint, the importance and methods of assessing the sustainability of buildings (BSAM) are established to enable project stakeholders to understand the expected and actual sustainability performance of their buildings (Thomson and El-Haram, 2018), but they are often applied in a technical and quantitative manner without considering other sustainability measures. Hence, the idea of research in an attempt to propose an integrated assessment model.
2 Method
Initially, based on the literature review, this study aims to identify sustainability indicators that are considered important worldwide. By improving the integration of these indicators, redundancy will be removed, thus arriving at a model that includes all environmental, cultural and social criteria. It consists of basic and sub-criteria under which the indicators fall. The present study utilized the expert judgment method to assess the proposed model and allocate weights to each indicator. This is a well-acknowledged and valid strategy, particularly when empirical data is scarce or challenging to obtain. Instances of expert evaluations, including weights, were collected from 13 out of 19 experts contacted in the fields of architecture and sustainability, urban renewal and construction project management and officials of some major projects in Riyadh. The study favored participants who possess extensive experience in sustainable architecture and urban development, particularly those who have worked in Riyadh or in comparable contexts. Research highlights the importance of having an expert background as a key method for obtaining reliable data on the fundamental aspects of the subject (Olander and Landin, 2005). In fact, the expert judgment framework builds on the sound foundations established by the literature by emphasizing the fact that expert judgment, where there is a lack of quantitative data, will yield crucial insights (Cashmore et al., 2004). This research adopts the ETE methodology to determine the evaluation criteria and their weights, which is an interactive method of prediction based on the opinion of a group of experts, or what is known as the Delphi method. Experts answered questionnaires to determine the weights of the criteria in three rounds where they received an anonymous summary of the experts’ predictions from the previous round along with the reasons they provided for their judgments. Several studies have shown that 10–12 expert respondents are sufficient to confirm the validity of the results, as these types of studies do not rely on statistical inference. The optimal weights for the main items derived from the survey data were then estimated using the best and worst case TOPSIS method. The results were reviewed with the expert respondents again in order to confirm the final weights (Wergin et al., 2018). Then,the study will examine leading architectural practices in Riyadh by evaluating a model that analyzes three major projects: the King Abdullah Petroleum Studies and Research Center, the King Abdullah Financial District, and the King Abdullah Financial District Metro Station. Data sources will include comprehensive site visits and detailed project documentation. These projects will be subjected to a comprehensive analysis according to the model that will be reached. See Figure 1.

3 Literature review
Sustainability in building construction can be defined as those practices and strategies that avoid harming the environment to the minimum and at the same time maximize resources utilization efficiency for occupants’ health improvement and that of society in general. It is holistic because buildings are not only physical but an integral part of ecological and social systems where they sit. The concept of sustainability leads to healthier living spaces, strength in a community, and proper use of natural resources. Decisions made by people towards sustainable building practices are valued according to the long-term return associated with construction, thus balancing the current needs against the future environmental and social outcome. This eventually offers a more sustainable and just built environment both for the present and for future generations. Applying sustainable construction methodologies, the industry is in an excellent position to make valuable contributions to reducing carbon emissions, preserving natural resources, and improving the quality of life for individuals and communities (Moshood et al., 2024). The following key features summarize the most important aspects of Green and Sustainable Building Construction:
• Community Participation and Certification: Local participation in some form of the planning process ensures that buildings efficiently meet the requirements and appeal of the intended occupants or users. Early involvement of stakeholders provides an open forum for debate and shared decision-making that may result in unique design solutions reflective of community perceptions. Perhaps more importantly, compliance with recognized sustainability standards and certifications, such as LEED and BREEAM, provides a roadmap not just for best practices but also for encouraging transparency and accountability in efforts toward sustainable building (Hamdan et al., 2021). These can create a benchmark against which the project can gain greater appeal in the market to environmentally conscious consumers and investors. Ultimately, community feedback serves to strengthen social bonds within the community and aligns the built environment with the aspirations of its residents.
• Resource Efficiency and Energy Management: Resource efficiency is a cornerstone of sustainable building construction, taking into account the impacts associated with the sourcing and utilization of materials (Aloshan, 2024). This could involve the use of renewable, recycled, and regionally sourced materials that reduce the carbon footprint from transportation and manufacturing intrinsic to the industry. Energy-efficient systems can be implemented to drastically reduce energy consumption while maintaining optimal efficiency, such as LED lighting, highly efficient HVAC systems, and smart technologies for energy monitoring (Khan et al., 2022). Integrating renewable energy sources, like solar panels and wind turbines, provides a greener and more stable energy supply for buildings. From a holistic perspective, managing energy at all levels helps to conserve resources and ensures economic viability, enabling local economies to thrive and boosting innovation related to sustainability in the building industry.
• Indoor Environmental Quality and Health: Indoor environmental quality is perhaps one of the most critical factors in maintaining the health and wellbeing of building occupants. Adequate ventilation, combined with the use of non-toxic and low-emitting materials, significantly improves indoor air quality, reducing respiratory illnesses and health complications. Additionally, maximizing natural lighting through proper window placement and skylights further enhances the atmosphere, contributing to a pleasant and productive environment. Incorporating biophilic design elements, including indoor plants and green walls, can enhance occupants’ feelings of connection with nature, thereby promoting mental wellbeing and overall satisfaction (Zhong et al., 2022). Creating spaces that prioritize comfort, health, and productivity adds value to individuals’ quality of life and positively impacts absenteeism and performance for organizations that own the buildings.
• Water Conservation and Waste Management: In regions where water supply is particularly scarce, water conservation is a significant aspect of sustainable construction. This can be achieved through the installation of rainwater collection systems and greywater recycling, leading to a substantial reduction in reliance on municipal water supplies. Additionally, low-flow fixtures and smart irrigation systems optimize every drop of water for practical use. Alongside these measures, holistic waste management strategies should be implemented during construction to minimize adverse impacts on the environment (Mohsen and Matarneh, 2023). This involves minimizing waste during construction by paying close attention to planning details and using recycled materials whenever possible. The concept of a circular economy, where discarded materials are reprocessed and reused, supports sustainability goals and fosters an environmentally ethical culture in the building industry.
• Site Selection and Environmental Integration: The choice of site is a vital aspect of sustainable building, where locations should be selected to minimize disturbances to existing ecosystems. Prioritizing sites that facilitate access to public transportation not only enhances a building’s sustainability but also supports environmentally friendly commuting options for residents. Furthermore, design strategies that preserve existing vegetation and wildlife habitats yield significant benefits for biodiversity and carbon sequestration, among other ecological advantages. Thoughtful integration of buildings into their natural surroundings promotes harmony between the built environment and the ecosystem, creating spaces that benefit both residents and local wildlife. In the end, sustainable site development is a crucial component of a broader process: crafting stronger, more resilient communities in harmony with their environments.
• Lifecycle Assessment and Resilience: A lifecycle assessment (LCA) of a building analyzes its environmental impact from construction through eventual demolition. This comprehensive analysis considers the ecological footprint of materials, energy use during operation, and possible end-of-life scenarios, enabling architects and builders to make informed decisions that mitigate harmful effects (Huang et al., 2020). Designing for resilience ensures that buildings can withstand the impacts of extreme weather events due to climate change and adapt to future needs or changes in use. Examples of resilient design principles include flood-resistant foundations, energy-efficient windows, and modular designs that allow for easy expansion or modification (Tagg et al., 2016). Investing in resiliency and adaptability ensures that buildings continue to contribute to long-term community sustainability while safeguarding occupants and the environment for years to come. Urban communities are the basic structures in the life of cities. They possess considerable resources, but at the same time are massive consumers of energy (Mohammed Abdullah Eben Saleh, 1998; Elsheshtawy, 2008). With applying a sustainable development approach, the urban community will be able to overcome problems such as over-imitation of modernist forms of architecture and/or excessive energy consumption. Evaluation methods have great potential to promote sustainable development in urban areas (Mashary Alnaim and Bay, 2023; Lak et al., 2021) if they are seen as a supportive tool for urban growth rather than a criticism tool. However, urban growth in new urban communities requires certain conditions: to achieve comprehensive gains in sustainable development, a balance must be struck in progress across societal, environmental and economic dimensions. This balance will bear fruit through an ecologically healthy environment, harmonious social coexistence and long-term economic growth (Ali et al., 2019).
Previous research on the issue of sustainable urban development in urban communities includes disciplines related to the evaluation of community conservation initiatives and case studies of sustainable communities (Fouseki and Nicolau, 2018). Until recently, this movement started to take hold in developed countries such as the United Kingdom, the United States, and Japan (Russell and Redmond, 2009).
Further, the New European Bauhaus initiative (Alvelos and Barreto, 2022), introduced in 2020 by the European Union, aims at accelerating the green transition across sectors of the economy, society, and everyday life. The solutions being put across entail rebuilding the cities, retrofit buildings to put in consideration affordable housing and construction in line with carbon neutrality (Karlsson Hjorth et al., 2021). Unlike previously similar projects which focused mainly on enhancement of physical setting, these new projects incorporate social, economic and environmental considerations into the development of a sustainable community.
Appropriate indicators can be applied, above all, within a comprehensive framework which allows for the evaluation of sustainable practices (Gao et al., 2020). The DSR model, proposed by UNCED, chose 58 indicators that evaluate 22 countries and regions (Goswami et al., 2017). Case studies regarding Vietnam, Mexico City, and a host of projects dealing with community level urban development projects such as Masdar Eco-City in UAE also show that the assessment toolsets utilized within a specific economic, social, and cultural background would greatly enhance development functions in terms of sustainability (United Nations, 2007). However, comprehensive assessment for most of these projects is missing in many aspects, with lots of details on location. For instance, Egyptian projects of urban development illustrate that developments can place pressures on surrounding older cities due to a lack of facilities and services (Selim et al., 2024). Even in some European cities with the successes of a sustained approach to urban development, there is quite a marked disparity between concept and reality (Shamaee et al., 2024). Quite an evident separation exists between theory and reality in the indicator frameworks for the holistic process of identifying issues and implementing a response against environmental degradation, in being able to measure social and cultural performance, and in communicating effectively through research and among stakeholders and decision-makers.
4 Building the proposed sustainability model
4.1 Classifying the most important sustainability indicators globally
Several major bodies play a significant role in advocating for environmental standards and certifications in sustainable architecture and building practices. Energy Star and the International Energy Agency, in particular, are vital in measuring energy efficiency based on the amount of energy used per square foot. (Jiang et al., 2019). The World Carbon Project or World Resources Institute is involved in measuring greenhouse gas emissions from buildings (Friedlingstein et al., 2019). The AWS Water Stewardship Alliance and the Global Water Partnership provide guidelines for efficient water use to address water conservation (Alodah, 2023). In indoor air quality, the WELL Building Standard and the WELL International Building Institute review indoor pollutant levels such as volatile organic compounds and carbon dioxide (Persily and Emmerich, 2011). These sustainable materials have ratings from entities such as LEED for the use of recycled or sustainably sourced materials and Cradle to Cradle Certified. Similarly, waste management practices are supported by LEED and ZWIA (Zero Waste Europe, 2020). Biodiversity in Good Company and the International Union for Conservation of Nature monitor biodiversity impacts (Marselle et al., 2021). The RE100 initiative and the World Renewable Energy Council call for a commitment to 100% renewable electricity among participating companies (The Climate Group, 2014). Finally, site sustainability and urban development impact can be assessed through certifications such as LEED-ND and BREEAM Communities (Adewumi et al., 2024).
ASHRAE (ASHRAE, 2020) standards address thermal comfort, while ISO 14040/14044 guides building lifecycle assessments. Similarly, the USGBC regulates the LEED (U.S. Green Building Council, 2024), certification process, which has 60 credit points on different sustainability measures. The criteria provided assess buildings on natural light and acoustic performance, with LEED credit awarded for daylight access and sound insulation. ILFI (International Living Future Institute, 2024) also sets very stringent standards through its Living Building Challenge; under the LBC, buildings must meet 20 indictors to achieve certification. For example, the CASBEE framework–particularly its city-focused iteration–allows for urban sustainability assessments, while BREEAM for Communities sets sustainability standards for community development. The German Urban Building Association evaluates new urban areas, including the DGNB (Weise Frank et al., 2022),valuates new urban districts, including the DGNB-NS certification. Additionally, the Assessment Standard of Green Eco-district (ASGE) (Khan et al., 2022) facilitates local eco-district evaluations (Adamu Salihi et al., 2024) For example, UN-Habitat (Burton, 2003), defines social indicators such as social equality in housing. In contrast, community participation is promoted through local development organizations. Health and safety compliance in building design is regulated by the Occupational Safety and Health Administration in cooperation with ISO 45001 (Minor, 2024). The economic impacts of the Global Reporting Initiative for construction projects under the Global Reporting Initiative are aligned with the targets set by the UN Sustainable Development Goals (Dubravská et al., 2020). The International Labor Organization reports on indicators related to job creation. It also allows for the preservation of community culture through local organizations and a way to ensure access to cultural facilities through local government agencies. IDEA (Chen et al., 2023) also advocates for civic engagement in governance issues to ensure that communities are involved and well informed about sustainable development practices. See Table 1.
Table 1. Overview of sustainability indicators for architecture and building practices.
While the above sustainability indicators available so far in architecture and construction practices provide constructive assessments, most fall short of representing a comprehensive assessment model for the environmental, economic, social, and cultural dimensions. Inclusion of other meaningful indicators of economic viability, such as return on investment and long-term cost savings, would also add more insight into financial sustainability. Social equity, access, and community wellbeing dimensions would have to be incorporated if the process is meaningfully to contribute to benefit all residents. Community engagement in cultural sustainability indicators would also ensure the preservation of local heritage and cultural identities. Only by applying all of those indicators within one assessment model will stakeholders understand what sustainability truly means and make better decisions to accomplish high-quality buildings that serve current and future generations as well.
4.1.1 Process of selecting suitable indicators for the local context
The Delphi method (Goktas and Yumusak, 2024), was thereafter used in collaboration with a multidisciplinary team of experts-in particular, 11 expert team members in the field of sustainable design and urban studies, besides experts working on key projects in Riyadh-to build and enhance these indicators. We commenced by defining the purpose of our research and its importance in terms of architectural sustainability in all of its comprehensive dimensions through in-person meetings and using Zoom technologies. A set of questions straightforward and concise were constructed in order to gauge the opinions of the experts on the various indications of sustainability. In the first round, comments with regards to the relevance and feasibility of the indicators were to be made by the experts. The responses were then analyzed to identify recurring and converging themes and contradictions using the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) (Hwang and Yoon, 1981). After two rounds, The development of the assessment criteria has been done to provide an orderly procedure toward effective and efficient impacts that different projects have, considering multidimensional criterion varying by their subcriteria and weight. This comprehensive framework evaluates architectural contributions in key areas of high importance: sustainability (Kibert, 2012a), economic integration, cultural value, community integration, and urban connectivity. We applied these filtered indicators to the three most prominent projects in Riyadh and followed the impact that these would have on sustainability outcomes across time. In this way, the Delphi method and TOPSIS technique has allowed structured and meaningful collaboration, with useful insight into the advance of sustainability in its comprehensive meaning. Accordingly, there were comments on the evaluation model according to sets of basic criteria. See Figure 2 the main criterion of fnvironmental; the most pertinent topic involves Sustainable Design (Fioretti et al., 2020), whereby aspects are included in the various stages of architectural projects by pointing out the adoption of the structures to meet the requirements for LEED certification, verification of efficiency for advanced technologies, and design feature assessment that would tackle environmental criterion (Federal Ministry for the Environment et al., 2016). LEED compliance review upholds the importance of recognized standards for sustainability and therefore reflects a project’s commitment to energy efficiency and care for the environment.
Figure 2. The primary criteria and sets of indicators following their integration and refinement.
Critical evaluation of advanced technologies is important, since high scores under this category reveal their relevance to enhancing the sustainability of the built environment. Besides that, creative solutions for energy consumption reduction and prioritizing sustainability give full support to the concept of great contribution to achieve sustainability goals in an architectural design. However, the sub-criterion was low in the selection of materials, which might imply difficulties in quantifying sustainability in material selections or a tendency towards greater prioritization in operational aspects over the consideration of materials. The additionally emphasizes the strategy of conserving water and enhancing indoor environmental quality. This reflects a comprehensive approach that takes into account both indoor and outdoor environmental effects (Kibert, 2012b). Another important certification is the Urban Heat Island Effect, which considers architectural strategies to limit temperature retention within the built-up environment. In this regard, improved urban climatic conditions stand to benefit from this factor.
An average score arises for the implementation of cool roofs and pavements; such cool surfaces are underlined as being important for managing surface temperatures while proposing a wider adoption across projects. The shading structure with greenery is more integrated, showing high contribution to the reduction of solar heat gain and increasing comfort in urban areas. Urban layout for maximizing natural ventilation has a relatively lower score, which shows that there is some improvement to be made in the strategy in order to enhance airflow effectively. The use of heat-resistant materials demonstrates awareness of their role in minimizing heat absorption, while the use of water features and thermal mass for cooling is functional and aesthetic. With respect to the exacerbation of urban heating, Beatley (2011) (Vanolo, 2015), supports such a stance by reviewing some of the benefits of biophilic design approaches in dealing with such urban challenges.
The third major criterion in envronmental facotor, Smart Building Technology, assesses advanced technologies intended for enhancement of energy efficiency and occupant comfort in modern architectural practice.
This includes assessment on energy-saving HVAC systems in relation to total energy consumption-a reinforcement in operation efficiency so key to sustainable design. The optimization of the use of energy through smart building technologies underlines their crucial role in energy management. In contrast, under sub-criterion IV, which represents the advanced lighting system, no score was obtained; this shows an important omission in stating the crucial role that lighting plays toward total sustainability and comfort of occupants. Building Automation Systems, BAS, have been evaluated to effectively manage building operations, an important aspect in smart architecture.
This work, in a nutshell, explains that the integration of renewable energies involving solar panels and wind turbines has an integral role to play in the sustainability attainment goals and, consequently, the demand reduction in general, which perfectly supports Lehmann (2011), who expressed that all the renewable technologies have transformed urban sustainability. The second most important factor is the Technological and economic Factor, because it expresses how collaboration with international firms influences design innovation and the introduction of sophisticated technologies. Laying an emphasis on a design innovation process in respect to collaboration assumes that partnerships with international experts might bring substantial added value to project quality, creativity, and sustainability, which corroborates insights by Fischer and Mone (2002) (Mach et al., 2017) concerning the use of expert panels in solving complex interdisciplinary problems.
The latter assessment also considers how international partnerships facilitate the incorporation of advanced systems and sustainable technologies, further underlining the benefits of global knowledge sharing in enhancing local ventures. The Role as Economic Hub criterion evaluates the contribution that a project brings out in developing Riyadh’s standing in the world economic arenaThis will involve its ability to attract international businesses, cross-border investment, and enhance the international standing of Riyadh (Scott, 2012). These kinds of evaluations bring out the correlation between architectural excellence and economic development, something considered of utmost importance in the task of long-term sustainability, as expressed by Vanolo (2015) (Stachura and Kuligowska, 2021). Who argue about the role that urban environment plays in the development of an economy.
Thirdly, cultural criterion assess the level of integration of the buildings under study with Saudi culture and respect for architectural heritage within the project. They also reflect a commitment to preserving local cultural identity, which has been considered vital in the case of maintaining authenticity in modern design and the desire to achieve cultural sustainability, as highlighted by Alsayyad (2001) (Moscatelli, 2022).
While a low score in promoting a sense of identity may indicate shortcomings in ensuring cultural relevance in current practices, sensitivity to local values and aesthetic preferences is very important for the sustainability of community heritage. Lastely, Community Connectivity, accounting for 10% of the evaluation, emphasizes the importance of pedestrian-friendly infrastructure and effective public transportation in promoting urban connectivity. By designing walkable environments with safe pathways and amenities, projects can enhance accessibility and encourage social interaction among residents. Additionally, well-integrated public transportation facilities facilitate seamless movement across the city, linking residents to essential services and opportunities. Lastly, interconnected public spaces create cohesive urban landscapes, fostering community engagement and enriching the urban experience. Overall, this criterion highlights the critical role of connectivity in developing vibrant and inclusive urban environments (Litman, 2021).
Table 2 include four main sections for each main criterion. After analyzing the results and extracting the weights that were done by experts to facilitate the analysis, a code was created for each sub-indicator that begins with the first letter of the main criterion, then the indicator number/indicator weight. All the numbers and values received from the experts were entered into the Excel statistics program to finally come up with a weight for each indicator. See Table 2.
Table 2. Weights and comprehensive criteria for the evaluation model.
The following diagrams represent the determination of ratios and weights for each of the primary and secondary criteria. Figure 3.
Figure 3. Diagrams represent the determination of ratios and weights for each of the primary and secondary criteria.
According to the above table and diagrams, the presence of four main criteria was confirmed:environmental (53.99%), technological and economic (24.36%), cultural (18.48%) and urban connectivity (3.17%). The environmental criterion is dominant, reflecting its decisive contribution to any form of sustainability assessment; it is supported by three sub-criteria and 15 indicators in total. The technological and economic criterion came in second place, with two sub-criteria and six indicators. The cultural criterion had two sub-criteria and six indicators with a weight of 18.48%. On the other hand, it had the least weight, which means that it could be a less important point in this context with 3.17%, and therefore one that should be given more attention in further research. See Figure 4.
Figure 4. Com analysis of evaluation criteria across environmental, technological, economic, cultural, and urban connectivity factors.
5 Application for case studies
All available information on the three projects was sent to the expert committee tasked with determining the weights, in addition to the researchers’ participation in the evaluation after determining the evaluation model and determining the weights see Table 3. These data collection tools included field visits to collect field observations and analytical descriptions, consultation with project stakeholders, and site photography in 2024. The case projects were selected due to their strategic importance within Riyadh, allowing the study to be more in-depth in their impacts. The three projects were also designed and implemented by international experts, which helps the research in monitoring how to deal with global trends. Given the climatic conditions in Riyadh, this study will receive another boost in environmental feasibility and special attention will be paid to how architects adapt their strategies to the prevailing environmental conditions. The next part contain short description for each project.
Table 3. Table showing the results of applying the proposed model to the case study (Environmental).
5.1 King fahd national library
The King Fahad National Library, recognized as one of the premier cultural institutions in the Kingdom of Saudi Arabia, officially commenced operations in November 2013 (Gerber Architekten, 2024). This monumental project was brought to life by Professor Eckhard Gerber and his esteemed team at Gerber Architekten, marking a significant milestone in the urban development and cultural landscape of Riyadh. See Figure 5.
Figure 5. The’s design, as illustrated in Figures 5, 6, acts as a catalyst for urban transformation, thoughtfully integrating modern architectural elements with the existing urban fabric. (Authors: April 2024).
The library’s design acts as a catalyst for urban transformation, thoughtfully integrating modern architectural elements with the existing urban fabric. It embodies a harmonious blend of contemporary design and Arabian cultural heritage, reflecting the values and traditions of the region. Key features include extensive collections of manuscripts, rare books, and digital resources that aim to promote knowledge, culture, and learning for Saudi citizens and visitors alike (Saudi Press Agency, 2024). Moreover, the library serves as a pivotal institution for educational programs, exhibitions, and cultural events, bolstering its role as a community hub. The project underscores the commitment of the Saudi government to invest in cultural infrastructur e that supports both preservation and innovation (Mashary Alnaim and Bay, 2023). The library project uses advanced tent fabric to achieve three goals. First, the tent structure recalls desert tent dwellings in Arab culture. Second, the building envelope provides shade, and reducing heat. Third, it combines a new technology material and a structural composition to combine the traditional and contemporary. The innovative design enhances the aesthetic appeal of the area and encourages community engagement and interaction, fostering a deeper appreciation for literature and scholarship. Its strategic location within the capital reinforces its importance as a center for knowledge and cultural exchange (Architizer, 2023).
The architectural design of the King Fahd National Library harmoniously combines the splendor of modern aesthetics with elements of Arab cultural heritage. Advanced materials such as glass and steel allow ample natural light to penetrate the interior spaces, ensuring a highly welcoming environment for visitors. The interior design enhances functionality and accessibility, with clear designations for reading, research and community activities areas. The design also reflects environmental concerns in its use of sustainable practices that increase energy efficiency.
5.2 Qasr Al-Hokm
The Qasr Al-Hokm District and the Great Mosque project, which was successfully completed in 1992, represents a significant achievement in the revitalization of the historical center of Riyadh. This project was recognized with the prestigious Aga Khan Award for Architecture for the 1993–1995 award cycle. Commissioned by the Arriyadh Development Authority, it embodies the second phase of a comprehensive plan aimed at rejuvenating the Qasr Al-Hokm District, which is known as the old heart of Riyadh (Royal Commission for Riyadh City, 2024). See Figure 6.
Figure 6. The architectural style reflects classic Saudi features, characterized by columns, courtyards, and narrow corridors, creating a seamless blend of functionality and traditional aesthetics. Axon, Anthony; Hewitt, Susan (2022–03–16). Saudi Arabia 1975–2020. BRILL. ISBN 978-90-04-51249-8.
The project encompasses not only the Great Mosque of Riyadh but also includes surrounding public squares, gates, towers, remnants of the old city wall, streets, and commercial facilities (Bay et al., 2022) The design, led by architect Rasem Badran, emphasizes the dynamic interaction between people and their environment, a principle he believes promotes a sense of community and ownership among residents. Badran’s approach creatively revitalizes and transforms the local Najdi architectural tradition, with outward-facing buildings that are framed by walls, gates, and towers (Architecture and Design Commission, 2021) See Figure 9.
