Reframing Sustainability Rating Systems to Emphasize Interconnected Benefits Increases Sustainable Design Practices among Engineers

The Role of Building-Integrated Greenery Systems in Building Sustainability Rating Systems

Building rating systems allow for the evaluation of environmental buildings’ impact throughout their lifecycle, thereby enabling improved design. The integration of vegetation into building envelopes, through green roofs and facades, provides multiple benefits that enhance the sustainability of a built environment. In arid climates, Building-Integrated Greenery Systems (BIGSs) contribute to energy savings and the improvement of the urban environment through evaporative cooling. However, the maintenance of these green systems requires efficient water use. This study thoroughly reviews six selected building sustainability certifications to determine the extent to which BIGSs are considered in the certification process. The findings indicate that BIGSs are not yet well integrated directly into these certifications. While the certifications recognize the biophilic effects on users and contributions to sustainable construction, they often overlook scientifically proven benefits such as acoustic insulation and urban noise reduction. This study highlights the importance of updating certification frameworks to fully incorporate the diverse advantages of BIGSs, especially in enhancing indoor environments and achieving energy savings.

Evaluation of Sustainable University Campuses and Sports Facilities from the Perspective of Administrators and Students: A Multiple Case Study

Sustainable higher education institutions contribute to the building of a sustainable society at regional and global levels by raising individuals with environmental awareness. Universities can also offer their stakeholders the opportunity to lead a healthy life with the sports fields on their campuses In this context, the “campuses” and “sports fields” of 6 Turkish universities which are in the top ten of the UI GreenMetric list (ranked by country), were analyzed in a holistic structure with a qualitative paradigm in terms of sustainability officers, sports facilities managers and students. The research was designed in a case study pattern and supported by in-depth interviews and document analysis. In this direction, it was analyzed within the scope of themes and sub-themes with the descriptive analysis method. As a result of the findings, it has been found that the sustainability studies in the examined universities are mainly carried out on environmental sustainability such as energy, water and waste management. It has been revealed that the reason for this for legal obligations. In addition, it has been determined that the sustainability initiatives of private universities are carried out both with various sustainability rating systems (STARS, THE, etc.) and within the framework of an integrated program with students. The inclusion of the opinions of the participants of different statuses in the study enabled us to reach multi-dimensional findings and results in the research fields.

A Comparative Analysis of Low-Carbon Design Strategies for China’s Higher Education Parks Based on Building and Urban Scale in Sustainability Rating Systems

In the global context of carbon neutrality, higher education parks are an important strategic position for achieving China’s goal of carbon peaking and carbon neutralization. Strategies from the perspective of life cycle to guide early low-carbon planning and design are an effective way to achieve carbon emission reduction goals. As the scale of university construction gradually expands, the “urban” attributes of them are becoming prominent. However, there is no quantitative study on analyzing the life cycle carbon emission strategies at both the building and urban scale based on sustainability rating systems. This study first extracts the design strategies according to BREEAM, LEED, DGNB and relative assessment standards for campuses and cities in China at the building and urban scale based on the 7-dimensional low-carbon strategy framework, then sorts out and compares the proportions of carbon-emission-related strategies across various dimensions and life cycle stages. It then summarizes the applications and concerns of low-carbon design strategies at different design scales. Finally, the weighting and calculation methods of life cycle carbon emissions in different sustainability rating systems are compared, the scope and methods of carbon emission benchmarks under different standards are compiled, and the evaluation method for locally applicable carbon emission benchmarks in China is proposed in light of China’s national conditions, which provides guidance for the design process and standard formulation.

Evaluating Building Sustainability Rating Systems: Standards and Methodologies for Energy-Water Based Assessment Criteria

EXPLORING THE SUSTAINABILITY OF CONCRETE BRIDGES

After the construction boom of the past 30-40 years, United Arab Emirates has been left with many costly structures that may or may not fulfill modern sustainability requirements. With the on-going economic recession seen by most of the world and a higher awareness among the population regarding the environmental and societal impact of construction, engineers and designers are carrying out sustainability studies for all kinds of infrastructure. Although most of past research has focused on sustainability rating of buildings, recent advances in this area shows a heightened interest in sustainability assessment of bridges as well. Several of the key sustainability indicators for buildings are also applicable for bridge; quantitative (construction cost and assembly, transportation of materials, service life, environmental impact, etc.) and qualitative (aesthetics, safety features, etc.). This paper contributes to an ongoing research project aimed at developing a sustainability rating system for bridges in the UAE. It includes a comprehensive survey designed to evaluate the relevance of current sustainability indicators for bridge projects within the region. The findings and analysis of this survey are discussed, providing insights into the adaptation of these sustainability metrics for UAE bridges.

Assessing Multilateral Development Bank ESG Safeguard Integration with International Sustainability Ratings

In an era where sustainability is paramount, this study critically assesses how multilateral development banks (MDBs) integrate internationally recognized sustainability indicators into their ESG safeguard policies. MDBs have historically incorporated policies to manage environmental and social risks in project financing; yet, protections against negative impacts in developing countries often remain insufficient. On the other hand, several infrastructure sustainability rating systems have been established around the world in recent decades due to economic growth and the importance of controlling environmental impacts associated with the construction sector. The purpose of this study was to analyze whether and how the indicators that these internationally recognized systems use to rate whether a project is sustainable are integrated into these safeguards by using several methodologies, including an analysis of existing documentation, a high-level matrix, and qualitative methods based on co-occurrences using specialized “atlas ti” software. The results show that MDBs’ coverage of financial, governance, and country risks lacks the sustainability focus found in these rating systems. Therefore, this study that concludes MDB safeguards must evolve, balancing comprehensive sustainability parameters and detailed management guidelines and addressing impacts beyond statutory frameworks to encourage stakeholder engagement for more sustainable infrastructure projects.

Charting climate adaptation integration in smart building rating systems: a comparative study

Introduction:As the world is engulfed with the growing impacts of climate change, the integration of climate adaptation measures into building performance requirements is essential. In the era of the fourth industrial revolution, smart buildings are expected to be the next frontier in the realm of building rating systems after sustainability-based one. Smart buildings can play a pivotal role in addressing the evolving challenges of changing climate due to their temporal and spatial cross-scale nature.Methods:This study assesses the integration of climate hazard adaptation options within four prominent smart building rating systems (SBRS). Using a sectoral analysis approach and a 4-point Likert scale, we systematically evaluate the extent to which these rating systems incorporate climate adaptation measures directly or indirectly across multiple building sectors. We identify strengths and weaknesses in each system’s approach, highlighting areas where adaptation options are more profoundly addressed and sectors that require further attention.Results:The evaluation results reveal variations in the comprehensiveness of climate adaptation integration among the smart building rating systems. The SRBS show a high level of integration of climate adaptation measures in the urban sectors intrinsically tied to the smart building paradigm, such as communication sector, and the human wellbeing and organization sector. Nevertheless, the study also revealed that SBRS almost universally fall short in covering other vital domains such as building envelope and structure, water and sanitation, and blue and green infrastructure.Discussions:Complementing the SBRS with sustainability rating systems (GBRS) can effectively address the limitations in climate adaptation integration within SBRS. Moreover, the inherent interconnectedness of smart buildings with their surrounding infrastructure and the broader urban environment underscores the importance of the cross-scale consideration in the building rating domain in general and in climate related topics in particular, this interconnectedness also highlights a smart building’s reliance on its surrounding context for optimal functionality and the interdependency between the building and urban scale.

Towards Sustainable Metal-to-Polymer Joining: A Comparative Study on Friction Stir Welding, Self-Piercing Riveting, and Adhesive Bonding

Friction stir welding (FSW) has gained increasing prominence in the realm of metal–plastic hybrid joints, yet its long-term sustainability remains a subject of uncertainty. This research investigates the sustainability aspect of FSW, positioning it against conventional techniques like adhesive bonding (AB) and self-piercing riveting (SPR). A comprehensive evaluation framework encompassing environmental, social, economic, and physical factors was employed, through which specified criteria were applied to select pertinent sustainability indicators across all dimensions to ensure a thorough assessment. In this study, two advanced multi-criteria decision-making methods (MCDM) were deployed for data normalization and aggregation. Sensitivity analysis was conducted to examine the robustness of the results. The outcomes yielded a sustainability rating system, facilitating a direct and insightful comparison with traditional methods. Based on the results of this study, SPR outperforms both FSW and AB in terms of overall sustainability with comparative average sustainability scores of 75.3%, 54.2%, and 35.3%, respectively. This study not only sheds light on the current state of FSW sustainability but also provides a valuable benchmark for decision-makers in selecting environmentally conscious methods for metal–plastic hybrid joints.

Sustainability of underground infrastructure – Part 1: Digitalisation-based carbon assessment and baseline for TBM tunnelling

Alongside the transition towards sustainable and renewable infrastructure and energy production, tunnelling projects that adopt tunnel boring machines (TBM) continue to increase in size and complexity. Life Cycle Assessment (LCA) methodologies have a significant impact on the Architecture, Engineering and Construction (AEC) industry, with a shift in focus to cost and carbon management across the infrastructure lifecycle through the use of digitalisation techniques and sustainability rating systems. This paper aims to develop a systematic framework to enhance the sustainability of underground infrastructure in the early design and construction stages, aiming for “build clever and efficiently”. This framework integrates digitalisation, carbon assessment standards, numerical modelling, and optimisation techniques to assess carbon emissions and establish benchmarks for construction products and processes. The approach uses parametric models to define tunnelling-related entities such as geological formations, TBM, and segments, designed with dimensional constraints that allow for adaptive modelling and interactions. Enabled by building information modelling (BIM) through parametric models enriched with domain properties, module-based carbon accounting is adopted to evaluate the footprint of material- and asset-level key emitters with functional units. Leveraging established databases, baselines for segmental lining designs and carbon reduction strategies are established. Through project-driven case studies, the correlations among geotechnical conditions, tunnel dimensions, and TBM operating parameters are developed to quantify TBM carbon emissions. A prototype programme demonstrates the framework's application on typical metro and road tunnels at different levels of details (LoD). This paper serves as a guideline for conducting embodied carbon assessments specifically tailored to TBM tunnelling, acknowledging the substantial contribution of the TBM construction process, which is controlled by geotechnical conditions.

Sustainability-Based Value Engineering Management as an Integrated Approach to Construction Projects

The integration of sustainability standards and value engineering methods in public education projects is a significant concern, as it ensures the well-being and sustainability goals of students, lecturers, and employees. This study aims to enhance sustainability within public education campuses by utilizing value engineering processes that establish a balanced correlation between the available budget costs and the sustainability costs that affect educational objectives, strategies, and the overall sustainability of the environment. In order to evaluate the integration of value engineering and the sustainability rating system “LEED protocols” for schools, the study utilized HAP (Hourly Analysis Program) software to perform numerical analysis, with the objective of improving environmental efficiency and cost-effectiveness in school buildings from the perspective of both male and female students. By applying this approach to all engineering disciplines, systems, and materials involved in the project, the study achieved impressive results, including a reduction in energy usage by 53.67%, a cost reduction of 27.48% from the total project budget, and 13 points earned in credit C1 and credit C2 in the Energy and Atmosphere EA category in LEED 2009. These findings are of great importance for the planning and execution of construction projects, specifically in the context of educational infrastructure, and provide valuable insights into the construction and renovation of school buildings, which can be used to enhance the safety, functionality, and aesthetic appeal of these facilities.

Application of the Sustainable Sites Initiative Rating System in Urban Green Space Construction in China—The Case of Xuhui Runway Park

The Sustainable Sites Initiative (SITES) is a comprehensive evaluation system for sustainable landscape, which has been promoted successfully and widely recognized in the landscape architecture industry. However, the existing research lacks attention to the applicability of SITES to urban green space construction projects in China. Therefore, exploring the application of the SITES evaluation system in the context of Chinese urban green space development is of great importance. Building upon theoretical research on sustainable landscapes, this study focuses on urban green space projects as the research carrier, with SITES as the subject of investigation. Utilizing the case study method, a thorough description and analysis of Xuhui Runway Park, a representative case officially certified by SITES in China, is provided. Across four stages—project initiation and planning, scheme design, construction, and operation—this study discusses the approaches employed in Chinese urban green space projects to meet the requirements of the SITES evaluation system. By evaluating the applicability of SITES to Chinese urban green space projects, identifying limitations in system promotion, and offering references for sustainable design practices, this study advances the application and promotion of SITES in China and contributes to the sustainable development of the landscape architecture industry.

Campus sustainability, organizational learning and sustainability reporting: an empirical analysis

Purpose Studies have shown that higher education institutions (HEIs) need to achieve deep organizational learning to develop and implement long-term strategies for responding to the climate crisis. This study aims to analyze the sustainability efforts of HEIs, in particular those who use the sustainability tracking, assessment and rating system (STARS), to ascertain what type of organizational learning is being achieved. Design/methodology/approach This paper does this by analyzing perceptions of learning amongst this group of HEIs. More specifically, it analyzes survey data regarding perceptions of types and system levels of organizational learning achieved by 116 HEIs in the USA that currently use or have used STARS in the past. The approach also aims to develop a macro view of the relationships between practicing campus sustainability, using sustainability reporting tools and learning as an organization. Findings An examination of the practice of campus sustainability and its relationship to organizational learning reveals that the use of sustainability reporting promotes broad learning, but deep learning at the level of the organization is seldom achieved. Practical implications Given the success of using sustainability reporting tools to diffuse knowledge and foster broad learning, this paper argues that such tools should incorporate more metrics relative to soft organizational characteristics of HEIs to shift organizational cultures and foster deeper organizational learning. Originality/value This work constitutes one of the few studies analyzing empirical data on campus sustainability, sustainability reporting and organizational learning for a large number of HEIs.

A novel framework to measure and promote smartness in neighborhoods

Although several sustainability rating systems have been proposed to assess the sustainability performance of projects, there is still no comprehensive framework to support the implementation of smart solutions within buildings and neighborhoods.To bridge this gap, this research project aims to propose an assessment framework to measure the smart readiness of neighborhood which can make a significant contribution in structuring and valuing existing potential technologies and smart solutions through various conceptual levels of smartness. This framework is developed using a mixed method approach through three phases: i) creating the taxonomy of smartening KPIs; ii) assigning weights to the KPIs by formulating determinant indexes reflecting sustainability and ESG targets (Customized based on four well-known certifications namely, LEED, BREEAM, DGNB, and GRESB); iii) introducing an output-based measurement method; finally, the framework is tested on a case study. The implementation of the smartening assessment framework through the different use of smart solutions and technologies resulted in a progressive sum of scores which emphasized the importance of stakeholders' engagement in planning smartening scenarios. This framework empowers managers and policymakers to clarify the objective level of smartness mostly through different social and environmental aspects and quantitatively distinguish the critical differences between smart and smarter neighborhoods.

Auditing and Rating Sustainability of Mediterranean Buildings, Neighbourhoods and Cities

Sustainability rating systems for the built environment involve a multitude of indicators that are based on different types of data. This work capitalizes on an existing multicriteria assessment method and supporting decision-making tool at building and neighbourhood scale, to develop an enhanced method and tool at city scale. The main sustainability issues at building and city scales include site and infrastructure, energy and resources consumption, environmental loadings, climate change, environmental quality, water, waste, transportation, services, social aspects, economy and governance. Approximately 300 indicators distributed among the different scales are used to describe and quantify the various facets of sustainability. Specifically, the building scale includes a pool of 80 indicators of which 17 are key performance indicators (KPIs), the neighbourhood scale has 133 indicators of which 14 are KPIs and the city scale has a total of 99 indicators of which 10 are KPIs that were new additions to the existing method. The emphasis in this paper is given on elaborating the key performance indicators for cities and demonstrating their applicability through a case study. The common method and tools provide a flexible assessment system for local authorities and stakeholders to develop and assess sustainability plans.

Towards Sustainable Roads: A Systematic Review of Triple-Bottom-Line-Based Assessment Methods

This review summarizes the methods and approaches for quantifying the sustainability performance of roads based on the Triple Bottom Line (TBL) concept. Furthermore, research gaps and challenges in the sustainability assessment of roads are identified. While prior studies explored the environmental and economic dimensions, no comprehensive overview of holistic sustainability assessment of roads exists. A systematic literature review (SLR) was conducted to identify relevant studies. Two assessment approaches were identified: (1) life-cycle-based approaches and (2) sustainability rating systems (SRS). Most of the reviewed studies applied life-cycle-based methods, such as Life Cycle Sustainability Assessment or a combination of Life Cycle Assessment, Life Cycle Costing, and selected social indicators. Heterogeneity in functional units was observed, with most studies opting for a dimension-based instead of a function-based reference. There was high variability regarding the life cycle stages, indicators, and impact assessment methods. Concerning the interpretation methods, most studies calculated a sustainability index or applied Multi-Criteria Decision-Making methods. The SRS presented a similar structure with different levels of aggregation. Furthermore, aspects such as planning, leadership, innovation, and construction activities were addressed. The results of this SLR contribute to expanding the knowledge regarding road sustainability and provide insight into common frameworks, guidelines, and best practices for the sustainability assessment of roads and pavements.

Assessing social equity considerations within transportation asset management

The impacts of transportation systems on people and communities are substantial but challenging to quantify. It requires significant effort and attention for transportation agencies to improve how social concepts such as equity are effectively incorporated into transportation asset management (TAM) plans and practices. This study, therefore, looked at TAM plans and practices to assess the current application of equity and suggested ways to improve equity incorporation into TAM at the state level. A content analysis was done on the 2019 TAM plans from all U.S. states, D.C., and Puerto Rico, and the results showed that equity-related words were rarely mentioned. This indicated that TAM is one of the sectors where equity is still marginalized, and there is a strong need to improve the incorporation of equity into TAM. The study then identified several equity definitions and measures that fit the context of pavement management and, as a result, TAM. Pavement management was used for demonstration purposes as pavements are a major type of asset managed by all state Departments of Transportation (DOTs). Definitions and measures were identified by reviewing documents from the USDOT and FHWA and three sustainability rating systems widely used in transportation: Envision, Greenroads, and INVEST. In addition to these definitions and measures, this study discussed several available guides and tools that would help agencies bring equity considerations into TAM, specifically at the state level. The results indicated that although some resources provide equity definitions and measures that can be used in TAM, more work is needed to develop them to match the practices and approaches used in this sector.

Determining The Indicators of Sustainability to Be Achieved in New Cities and Urban Communities

Indicators are one of the effective mechanisms for achieving and measuring the targeted progress of urban communities at their different levels towards the desired and planned results for development, and to determine the indicators of sustainability to be achieved in new cities and urban communities. Some sustainability rating systems for residential neighborhoods in different countries will be studied, as well as the Egyptian Rating System (Gprs). And extracting the most important indicators and determinants of sustainability that you use to evaluate buildings and residential neighborhoods, as well as studying some other aspects that help to reach the sustainability indicators that are required to be achieved at the city level, and through this, the most important sustainability indicators will be reached and limited as basic indicators for achieving and measuring sustainability in new cities and urban communities, and it is possible to add or delete Indicators, including according to the nature of the cities (tourist - industrial – coastal-….) .
