Vernacular architecture offers valuable technological and typological solutions rooted in knowledge systems that connect environmental, social, economic, and cultural contexts. This paper introduces the Heritage for People Platform, a collaborative digital tool developed under the VerSus+ project (Creative Europe Program), aimed at organising and disseminating vernacular architectural knowledge with a focus on sustainable practices that are both culturally and environmentally conscious. The platform builds upon lessons learned from similar projects, offering key improvements such as the adoption of a Case-Based Reasoning methodology, which organises examples by geographic location, materials, and intervention types. A structured classification system based on sustainability principles and strategies enables cross-disciplinary research and comparison. The design process was highly participatory, incorporating user feedback at every stage to ensure the platform is accessible to a wide range of users, including designers, scholars, craftspeople, and the general public. A cross-device, user-centered approach further broadens its accessibility. The platform provides a public, web-based geospatial repository where users can create, update, and explore a dynamic collection of artefacts, design models, people, and institutions from across the globe. This tool marks a significant advance in promoting and preserving both physical and intangible heritage, with strong educational and practical applications for sustainable architecture. The paper details the theoretical framework and real-world potential of the platform as a critical resource for promoting sustainability in the built environment. [ABSTRACT FROM AUTHOR]

Biomimicry creates designs inspired by nature and uses ecological benchmarks to assess their sustainability. It is believed that biomimicry can help society produce and consume in more sustainable ways, as well as address some of the key challenges facing the world today. However, research into the applications of and possible barriers to using biomimicry for creating more sustainable Architectural, Engineering and Construction (AEC) projects is still limited. This paper addresses this gap by undertaking and analysing twelve semi-structured interviews with leading global experts and practitioners in the field of biomimicry as applied to the built environment industry. The study identifies substantial potential in the use of biomimicry in AEC projects, including the following: adopting circular approaches; enhancing interactions between human and natural infrastructure; optimising material and energy use; recycling and re-use of materials; reducing time and costs; plus more collaborative and interdisciplinary working. However, a wide range of multifaceted barriers also exist that are currently hindering the exploration and exploitation of this potential, including the following: lack of knowledge; insufficient research and testing at the scale of AEC projects; fragmentation, poor communication and traditional nature of the industry; perception of high risks and costs; as well as outdated and unsuitable legislation and planning processes.

An innovative procedure is therefore designed to serve planning and design stages, to underscore the importance of incorporating "design for circularity" as a preliminary, yet essential step to a successful transition to a circular economy for projects in the built environment sector. The reciprocal interactions and impacts of a transition to circular economy on broad policies at national economy level are discussed against the backdrop of the built environment sector. The paper brings to light the necessity of paying attention to the contextual socio-technical aspects that shape a transition to a circular economy in an advanced economy like Australia, where research and knowledge generation are equally important along with those of finical and economic considerations.

This paper introduces a transformative "living" hypothesis in architecture and engineering, proposing a paradigm shift from conventional design to regenerative, ecologically interconnected resilient systems. At the heart of our hypothesis is the integration of earth-bound materials and bioreceptive surfaces through metabolic exchanges that can be directly monitored via bioelectricity using advanced computational models and cooperative governance structures. This innovative approach that links the living world with natural materials and digital computing, aims to foster sustainable urban development that dynamically and meaningfully responds to ecological shifts, thereby enhancing social sustainability and environmental resilience. Founded on an active relationship with Earth Based Materials (EBMs) our work operationalises the foundational link between organic life and inorganic matter, e.g., minerals, to establish a dynamic relationship between building materials, and ecological systems drawing on the foundational metabolisms of microbes. To enable this ambitious synthesis, our work builds upon and diverges from traditional foundations by operationalizing actor-network theory, new materialism, and regenerative design principles through the application of bioelectrical microbes to "living" materials and digital twins. We propose a novel resilience framework that not only advocates for a symbiotic relationship between human habitats and natural ecosystems but also outlines practical pathways for the creation of adaptive, self-organizing built environments that are informed by data collection and metabolic feedback loops. These environments are fundamentally regenerative, dynamic, and environmentally responsive in ways that can be understood and engaged by human engineers and designers, transcending current sustainability and resilience targets through a methodology rooted in interdisciplinary collaboration. We address challenges such as regulatory barriers, lack of standardization, and perceptions of inferiority compared to conventional materials, proposing a new standardization framework adaptable to the unique properties of these materials. Our vision is supported by advanced predictive digital modelling techniques and sensors, including the integration of biofilms that generate action potentials, enabling the development of Digital Twins that respond to metabolic signals to enhance sustainability, biodiversity, and ultimately generate environmentally positive socio-economic outcomes. This paper reviews existing methodologies to establish an overview of state-of-the-art developments and offers a clear, actionable plan and recommendations for the realization of regenerative and resilient systems in urban development. It contributes a unique perspective on sustainable urban development, emphasizing the need for a holistic approach, which integrates the foundational metabolism of microbes, assisted by big biological data and artificial intelligences that act in concert to respect both the environment and the intricate dynamics of living systems.

Implementing circular economy principles in the built environment significantly reduces raw material extraction and generated waste. A transition is essential, especially as it accounts for 40-60% of global raw material extraction and 33% of total waste in the European Union. This paper shows the methodological approach to generating a digital Building model to enable circular economy in the early design stage by coupling Generative Design methods, enabling automated variant generation of Digital building models, Building Information Modelling objects, and assessment algorithms to evaluate the environmental impact and circularity. By visualising the assessments of the generated variants of (so-called) Circular Twins in a Virtual Reality environment, including user interaction with a voice-controlled Virtual Agent, the digital Circular Twin ecosystem enables the early implementation of the goals of the circular economy and sustainability in Architecture, Engineering and Construction.

As the global community strives to address the pressing challenges of environmental degradation and social inequality, the role of architecture in promoting sustainable development has gained unprecedented significance. This paper explores the intrinsic connection between architecture and sustainable development, focusing on Egypt as a case study. The research follows theoretical and practical application methodology, where case studies and solutions are applied. Egypt, with its rich historical heritage and rapidly urbanizing cities, presents a unique context to investigate how the built environment can contribute to achieving the Sustainable Development Goals (SDGs) outlined by the United Nations. This study adopts a multidisciplinary approach, integrating architectural analysis, urban planning principles, environmental science, and social studies to examine the various ways in which architecture influences and interacts with sustainability goals. Case Studies include two locations in Egypt as future concepts to solve problems: Downtown Cairo and Nubia-Aswan, where ideas were introduced towards a better quality of life. The findings of this research underscore the importance of collaboration between various stakeholders, such as government bodies, non-governmental organizations, architects, and the public, to create a holistic approach to sustainable architectural design and urban planning towards resilient communities. The paper also emphasizes the need for education and awareness campaigns to foster a culture of sustainability within the architectural and construction sectors. Proposed projects were introduced in the International Union of Architects (UIA) World Congress of Architects in Copenhagen 2023 and published in UIA Guidebook 2030. [ABSTRACT FROM AUTHOR]

Purpose: Starting with the notion that each building has an overall life cycle, the paper uses building-based and investment-based life cycles to identify likely decision points for renovations, including sustainability enhancements, and identifies patterns in sustainability decisions. Design/methodology/approach: This real estate insights paper considers how commercial real estate and the built environment it creates, owns and manages impacts the sustainability of urban areas and the globe. By combining building-based and investment-based life cycles, it is possible to develop a unique "sustainability enhancement quotient" for individual buildings and the built environment for an urban area over a given time interval. Findings: Using two life cycles allows the identification and likelihood of sustainability decision points. The same life cycles and decision points are used to consider the likely extent of such renovations. This is in addition to continuous consideration of renovations producing economic benefits in the form of lower operating costs and quick return of capital. Research limitations/implications: Useful for investment decision-making and policy design and implementation. Practical implications: This is a useful tool for public and private decision making. It is suggested that the sustainability enhancement quotient may be used to design and implement policies and decisions maximising the likelihood of sustainability enhancement in an urban area's built environment. Social implications: Provides a framework for more effective sustainability decisions and public policy. The public-private interplay inherent in every building is emphasised throughout. Originality/value: Original combination of existing tools. [ABSTRACT FROM AUTHOR]

Threats to the health of our environment are numerous. Much research in science and engineering is devoted to documenting, understanding, and attempting to mitigate the harm itself. The root challenge for sustainability, however, is human behavior. As such, changes to human behaviors and the internal processes that drive them are also essential. Critical to understanding sustainability‐related behaviors is the individual's conceptualization of the natural world and its components and processes. The papers in this topiCS issue address these conceptualizations by drawing from anthropological, linguistic, educational, philosophical, and social cognitive perspectives as well as traditional psychological approaches to the study of concepts and their development in children. They engage with many domains bearing on environmental sustainability including climate change, biodiversity, land and water conservation, resource use, and design of the built environment. They coalesce around four broad themes: (a) What people know (or believe) about nature broadly and about specific aspects of nature, and how they acquire and use this knowledge; (b) how knowledge is expressed and shared via language; (c) how knowledge and beliefs interact with affective, social, and motivational influences to yield attitudes and behaviors; and (d) how members of different cultures and speakers of different languages differ in these ways. The papers also point to lessons for advancing sustainability via public policy and public messaging, education, conservation and nature management, and design of the built environment. The root challenge for environmental sustainability is human behavior. Critical to understanding sustainability‐related behaviors is the individual's conceptualization of the natural world and its components and processes. The papers in this issue address these conceptualizations by drawing from anthropological, linguistic, educational, philosophical, and social cognitive perspectives as well as traditional psychological approaches to the study of concepts and their development in children.

Purpose: This paper aims to explore the intellectual structure shaping the circular economy (CE) discourse within the built environment in Africa. Design/methodology/approach: The study adopted a bibliometric analysis approach to explore the intellectual structure of CE in the built environment in Africa. The authors collected 31 papers published between 2005 and 2021 from the Scopus database and used VOSviewer for data analysis. Findings: The findings show that there are six clusters shaping the intellectual structure: demolition, material recovery and reuse; waste as a resource; cellulose and agro-based materials; resilience and low-carbon footprint; recycling materials; and the fourth industrial revolution. The two most cited scholars had three publications each, while the top journal was Resources, Conservation and Recycling. The dominant concepts included CE, sustainability, alternative materials, waste management, lifecycle, demolition and climate change. The study concludes that there is low CE research output in Africa, which implies that the concept is either novel or facing resistance. Research limitations/implications: The data were drawn from one database, Scopus; hence, adoption of alternative databases such as Web of Science, Google Scholar and Dimensions could potentially have yielded a higher number of articles for analysis which potentially would result in different conclusions on the subject understudy. Originality/value: This study made a significant contribution by articulating the CE intellectual structure in the built environment, identified prominent scholars and academic platforms responsible for promoting circularity in Africa.

This paper delves into the investigation and inventory of cob buildings within the Guérande Peninsula, employing an interdisciplinary framework merging academic inquiry, fieldwork, and digital cartographic methodologies. Against the backdrop of escalating environmental concerns within the construction sector, raw earth construction emerges as a compelling avenue for sustainable building practices due to its low embodied energy and reversible characteristics. Despite historical prevalence in regions such as northwest France, traditional earth-building techniques have experienced waning prominence with the advent of industrial materials. However, the resurgence of interest in raw earth's minimal carbon footprint has catalyzed renewed attention towards earth-building methods. Through a meticulous investigation methodology, this study identifies and analyzes 802 potentially old cob buildings, with 46 structures confirmed as cob constructions. Employing statistical analyses of building characteristics, including wall and lift heights, preservation states, and geographical distributions, this research sheds light on the significance of preserving cob heritage amidst rapid urbanization. The findings underscore the imperative for ongoing research and awareness efforts to safeguard these vernacular architectural traditions. By illuminating centuries-old building practices, this research contributes to the scholarly discourse on sustainable construction methodologies and local cultural preservation. Moreover, it underscores the necessity of integrating traditional knowledge systems with contemporary sustainability initiatives to foster resilience and longevity within the built environment.

Purpose: The Heating, Ventilation and Air Conditioning (HVAC) system is a significant energy consumer in built environments, and the building energy consumption could be minimised by optimising HVAC controls. Hence, this paper aims to investigate the applicability of Variable Refrigerant Flow (VRF) air conditioning systems for optimising the indoor comfort of buildings in Sri Lanka. Design/methodology/approach: To address the research aim, the quantitative approach following the survey research strategy was deployed. Data collected through questionnaires were analysed using descriptive statistical tools, including Mean Rating (MR), Relative Important Index (RII) and Standard Deviation (SD). Findings: The findings revealed that VRF systems are popularly used in Sri Lankan apartment buildings. Furthermore, energy efficiency and comfort were recognised as the most significant top-ranked benefits, while ventilation issues and initial cost were recognised as significant challenges. Moreover, the allocation of trained technicians and provision of proper ventilation through a Dedicated Outdoor Air System (DOAS) were highlighted as applicable mitigation strategies for the identified challenges in VRFs. Practical implications: The study recommends VRF systems as a suitable technology to ensure energy efficiency, reduce GHG emissions and achieve climate performance within the built environment. The opportunities for adopting VRF systems for developing countries could be explored based on the research findings. The identified challenges would assist the design engineers and facilities professionals to devise suitable strategies to mitigate issues of VRF systems in developing countries. Originality/value: This research provides empirical proof of the energy efficiency and comfort aspects of VRFs. The study has explored and recommended VRF technology as a beneficial application to overcome the persistent energy crisis in developing countries. [ABSTRACT FROM AUTHOR]

Corporations develop, own, operate, and direct a majority of all assets in the built environment (BE), and the development and operation of these assets is a significant component of global sustainability. In recent years corporate sustainability action for large companies has trended toward becoming embedded within corporate environmental, social, and governance (ESG) programs. However, ESG strategies and their impacts are only beginning to be understood by large corporations, with little definition for how to apply, measure, and assess the effectiveness of ESG practices. Every industry sector has some connection to the BE, and construction engineering, and management (CEM) professionals contribute to all phases of the BE life cycle, including development, design, construction, and operations. As such, CEM professionals are vital in developing and implementing sustainability practices specifically for corporations with large footprints in the BE. The purpose of this research was to assess the extent to which the BE is impacted by corporate sustainability practice through ESG programs. The research utilized a grounded theory approach to explore sustainability practices directly associated with the BE from companies within all 11 Global Industry Classification Standard (GICS) sectors. It presents a representative model that encapsulates current organizational ESG strategy, through the development of ESG action categories. A total of 24 different ESG action categories are presented and defined. The research further identifies those ESG actions commonly applied by large corporations and how these actions differ by GICS sector. This research indicates that over half of corporate ESG actions are related to the BE. Ultimately, this paper demonstrates the necessary role that CEM professionals should play in influencing sustainability practice through ESG strategy and action within the BE. Practical Applications: ESG is a rising topic in corporate sustainability and is becoming increasingly tied to financial instruments such as sustainable investment indexes or green bonds. The rise of ESG presents both a challenge and an opportunity for CEM professionals. Large entities are expected to publish ESG reports sharing their sustainability progress, including entities in which CEM professionals are key figures, such as power utilities. The advent of ESG reporting presents a challenge to CEM professionals because they need to learn to navigate ESG reporting or risk losing access to valuable funding opportunities when subject to ESG measurement and evaluation. It also presents an opportunity for CEM professionals because they are uniquely qualified to lead ESG efforts as BE experts. ESG and the BE are strongly related, with most ESG work being environmental in nature. CEM professionals have been actively involved in improving the sustainability of BE assets as they relate to the environment for many years. To leverage this experience, CEM professionals need to take an active part in recommending improvements to corporate ESG strategy. Corporations themselves must also actively seek to engage CEM professionals in their ESG decision making processes and advisory boards. [ABSTRACT FROM AUTHOR]

Environmental product declarations (EPD) to EN 15804 provide information about the embodied carbon dioxide of construction products – their life cycle greenhouse gas emissions – alongside reporting the use of renewable and non-renewable primary energy and secondary fuels, among the other environmental indicators. As the number of EPD to EN 15804 increases, they become a useful data resource to consider these impacts. In moving towards a reduction in the embodied carbon of products, it is necessary to use renewable energy resources efficiently to allow the transition to net zero; this is because of the increasing demands on renewable energy to decarbonise industry, transport and domestic energy consumption and the limited capacity to expand renewable generation. This paper reviews published EPD data for structural and reinforcing steels, cement, bricks and structural timber products, and considers, for the cradle to gate 'product' life cycle stage, exploring the relationship of embodied carbon with embodied energy (total energy used), the balance of renewable and non-renewable energy, and the efficient use of energy. It is found, for bricks and timber, that EPD show products that use a greater percentage of renewable energy have higher embodied energy, suggesting a less efficient use of renewable energy for these products.

Since the industrial revolution, the civil engineers who created a built environment for a civilisation that is based on fossil fuel have been admired. For over 250 years, engineers have been educated and trained for the 'upslope' of using ever more resources to fuel engineering needs. However, there is now an urgent requirement to enter an era that is an order of magnitude shorter, and which is on the steep 'downslope' towards net-zero carbon dioxide by 2050 or earlier. The difference between what it meant to be an engineer on the upslope and what it means to be engineer on the downslope is colossal. The first step for all educators is to realise this, to embrace it and to be part of the solution by instilling a downslope mentality in engineering students. The Joint Board of Moderators (JBM) has recently reviewed and updated its guidelines for universities. It has placed the climate emergency central to the education of future civil engineers. This paper describes the background to, and details of, the changes made by the JBM. Given that creativity is enhanced through these additional challenges, what could possibly be more exciting for today's engineering students than knowing that they will lead the profession in achieving massive reductions in emissions, to the benefit of all humanity? The JBM, and society, require of civil engineering education that this ambition is fulfilled. [ABSTRACT FROM AUTHOR]

Purpose: This viewpoint paper aims to discuss sustainable digitalisation of facilities management (FM) through the implementation of the newly recognised International Organization for Standardization (ISO) standards within the ISO 41000 series. Design/methodology/approach: This viewpoint paper provides a review of the literature of the recent ISO documents and academic study. The content is also dependent on the authors' opinions and interpretation. Findings: FM is currently shifting emphasis towards a strategic focus through the adoption of the new recognised international ISO standards that consider sustainable digitalisation in business decisions. However, the FM sector is encountering potential risks to the implementation of the new recognised international ISO standards. Digitalisation is one kind of force that has shaped the management of the built environment and FM recently and rapidly, especially in the Covid-19 period. This is impacting the FM industry. As standardisation aims at establishing a constantly evolving baseline of proven practices, standardisation can be considered a part of sustainable FM. It is believed that standardised and strategic level support is crucial for the smooth adoption of sustainable FM practices and processes. Standards such as the ISO standards, applied to the global FM industry, help in objectively quantifying the added value of FM to the core business. Advanced technology and digitalisation can contribute to the sustainability of any profession and industry, but it also requires a community to tackle the problems. Originality/value: This paper contributes to the FM industry by making recommendations for improvement in the use of digitalisation. In summary, the significant finding of this viewpoint paper is that digitalisation offers both possibilities and problems in the application of the new recognised international ISO standards within the FM industry.

Recently, there has been an increasing effort to promote energy efficiency, using renewable energies and electric mobility to achieve a more sustainable future and even carbon neutrality by 2050. This paper aims to understand if combining these technologies leads to a win–win solution. For that, the system's characteristics that will be used for the simulation were defined as a residential community consumption scenario with and without electric vehicles charging overnight. The simulation was completed in software, and eight scenarios were tested: high population density/low population density with/without electric mobility and hourly tariff/simple tariff. After these scenarios had been tested, the conclusion was that the low population density and hourly tariff without and with electric mobility were the best two cases economically (in terms of levelized cost of energy, net present costs, and savings) and environmentally, and the worst was high population density with hourly tariff and electric mobility. Other scenarios were then tested, including changes in the load curve, namely a commercial load curve, and changes in the load curve of electric vehicle chargers, mainly daytime charging. The conclusion was that even though the initial hypothesis did not lead to a win–win solution, with changes in the hypothesis, the integration of electric mobility in energy communities might lead to that.

The impact of global climate change on the built environment emphasizes the need for sustainable development goals (SDGs) using technological solutions, such as the Internet of Things (IoT). The significance of innovative building assessment (BA) tools plays a pivotal role in bridging the existing gap between the theoretical and actual operational performance of buildings. The main research question is how can a new generation of BA tools leverage the IoT to optimize occupant well-being and achieve SDGs' targets. This article delves into the pivotal role played by the IoT and occupant-centric concepts in advancing sustainability initiatives and facilitating the achievement of SDGs. The novelty of this paper lies in its exploration of the current state of IoT integration as a strategic imperative for SDGs' achievement and climate change mitigation. Consequently, a paradigm shift is evident in this work, showcasing a comprehensive comparison between conventional and IoT occupant-centric BA tools and introducing a correlation study between IoT occupant-centric systems and future SDGs' targets. Lastly, current gaps and valuable insights into future research possibilities are offered. [ABSTRACT FROM AUTHOR]

The "City in a Park" (CIP) is a new concept of urban transformation and development proposed in China in recent years, guiding the construction of healthy and sustainable living environments. This paper analyzes urban planning based on the CIP concept from a synergetic perspective, aiming to explore how the integrated planning of ecological spaces and built environments can promote systematic sustainable development in ecology, economy, and society. This research employs methods including document collection, unstructured interviews, field observations, and participatory observation, focusing on a case study of the Sichuan Tianfu New Area (STNA), a demonstration zone for the CIP. The study finds that the planning of the STNA extends the planning scope of urban ecological spaces beyond the traditional urban construction boundaries, not only preserving the natural resources but also enhancing the city's overall sustainability through regional ecological services. By designing ecological spaces as green infrastructure that connects urban and rural areas, the primary sector is more readily integrated with the secondary and tertiary sectors, facilitating the integration of the urban and rural infrastructure and industries. The STNA integrates urban and rural administrative divisions, builds a cross-departmental collaborative management platform, and guides public participation in the planning process, ensuring the efficiency and effectiveness of planning implementation and enhancing the equitable sharing of social services. This research provides new insights into comprehensive, cross-disciplinary, and ecology-oriented urban planning. It offers evidence for an understanding of the application pathways and effects of the CIP concept in urban planning practice and provides valuable experience for other cities to promote harmonious coexistence between the city and nature.

Indoor environmental quality (IEQ) significantly impacts human health, well-being, and productivity. However, a comprehensive and in-depth review of the combined effects of IAQ and other multi-domain factors on human productivity is lacking. There has not been any prior review that encapsulates the impact of multi-domain factors on productivity and physiological responses of occupants. To address this gap, this review paper investigates and highlights the impact of IAQ and multi-domain factors (thermal, visual, and acoustic) on human productivity and occupant well-being in the built environment. The review explores various research methods, including evaluation of human productivity and creativity, data collection, and physiological signal analysis. We also examined the interactions between IAQ and multi-domain factors, as well as strategies for optimizing productivity through integrated building design and smart systems. The key findings from this review reveal that IAQ significantly impacts human productivity and occupant well-being, with interactions between IAQ and other IEQ factors further impacting these effects. Despite advances in the field, there are several limitations and gaps in the current research methods and study designs, including small sample sizes, limited and insufficient experimental design and control, reliance on laboratory or simulated environments, lack of follow-up and long-term data, and lack of robust performance metrics. The review proposes future research directions, including specific applications, and follow-up work to address these limitations and further advance the understanding of IAQ and multi-domain factors in the built environment. The implications of this review for policy and practice include the need for holistic and integrated approaches to IAQ and IEQ management, with a focus on creating healthy and productive indoor environments. This review emphasizes the importance of considering the complex interplay between IAQ and multi-domain factors, as well as the potentials of adopting smart control systems and sustainable design strategies to optimize productivity and occupant well-being in the built environment. By addressing these critical issues, we can enhance the overall quality of life for building occupants and contribute to a more sustainable future. [ABSTRACT FROM AUTHOR]

There is a need within society to manage its impacts on the environment. The International Organization for Standardization (ISO) ISO 14001 tool, based on the original BS 7750 standard, was created in 1996 and subsequently updated in 2004 and 2015; it has become the most prevalent type of environmental management system (EMS) adopted worldwide. Engineering and construction organisations wanting to implement ISO 14001 should be fully acquainted with the advantages and disadvantages of adopting an EMS. Using the Scopus academic database, this study used the Preferred Reporting Items for Systematic Reviews and Meta-analyses method to identify and select publications (since 1999) for systematic review. Examination of the chosen articles (n = 46) revealed a limited number of works per annum, with a peak in 2011 (n = 6). The most frequently reported benefits are 'enrichment of green corporate and public image', 'improved environmental performance' and 'regulation compliance', while the barriers are 'costs', 'lack of experience, expertise or knowledge' and 'lack of training'. Further analysis, using the VOSviewer software, shows the network relationships between article keywords, notably that sustainability is increasingly listed (since 2011) and links with most other keywords. This suggests that the engineering and construction sectors may be seeing beyond the cost barrier and are realising the positive difference that ISO 14001 can contribute to their operations, their local/national communities and the UN Sustainable Development Goals.

Aerogels, with their exceptional properties such as high insulation performance, lightness, and eco-friendliness, present immense potential for use in the construction industry. This paper reviews the progress in research and application of various types of aerogels in construction, highlighting notable case studies demonstrating energy efficiency gains and sustainability impacts. It delves into the lifecycle of aerogels, discussing environmental implications at each stage. Despite their potential, aerogels face certain limitations including production complexity, brittleness, and high cost which hinder their widespread adoption. The paper further discusses these challenges and highlights the need for continuous research and development efforts to overcome them, with a view to achieving more scalable production, enhanced mechanical properties, and cost reduction. Looking forward, the paper discusses the expansive horizon of aerogel research, emphasizing the potential of smart aerogels, their integration with renewable energy systems, and exploring the possibility of recycling or creating bio-based aerogels to enhance their overall sustainability. While still in early stages, aerogels promise to be a major contributor to the future of construction, leading to more sustainable and efficient built environments. [ABSTRACT FROM AUTHOR]

It is a well-known issue that the 2050 target of carbon emissions neutrality will be reached only with the co-operation of all the interested sectors, and the construction sector could be one of the main contributors to this change. With the built environment globally responsible for about 40% of annual global energy-related CO2 emissions, the construction sector offers an important opportunity to drive transformative change and presents the most challenging mitigation potential among all industrial sectors, which also brings opportunities for adopting sustainability practices and increasing resilience. This paper presents a systematic literature review of those two pivotal concepts to reach the decarbonization goal: sustainability and resilience. Starting from an extensive literature review (2536 scientific documents) based on the PRISMA statement, the definitions and assessment methodologies of those concepts for the construction sector have been studied. The methodological approach followed for their analysis has been conducted on a first selection of 42 documents, further reduced to 12 by using clear inclusion criteria to identify the integrated assessment procedures. The main goal of this study is to clarify the correlation between sustainability and resilience concepts for constructions and their integrated assessment, in line with the latest regulations and market needs. The results show that, currently, sustainability and resilience are mainly evaluated in a distinct way to obtain building energy performance certificates, as well as to quantify the building market value and its complementary contribution to the 'energy efficiency first' principle and energy-saving targets towards the emergent issue of climate change. Few works focus on the integrated assessment of both concepts considering the construction industries' point of view about materials and/or systems for buildings. The novelty of this study is the critical review of the current sustainability and resilience integrated assessment methods used for the construction value chain, declined for four main target groups. Researchers, policymakers, industries, and professionals could gain dedicated insights and practical suggestions to put in practice the elements of circular economy, ecological innovation, and cleaner production, which are essential in order to drive the decarbonization of the built environment.

The built environment is subject to various defects as it ages. A well-maintained built environment depends on surveying activities to inspect, document, and rehabilitate the defects that occurred. The advancement of digital technologies paves the pathway towards (1) comprehensive defect inspection by systematic mapping, (2) their consistent documentation by digital modeling, and (3) timely retrofitting by proactive management. However, the three steps of defect mapping, modeling, and management (D3M) remain largely fragmented and have yet to be synergized. Exploiting the pivotal role of building information modeling (BIM) in built asset management, this paper puts forward a cohesive framework for integrated D3M. It leverages the rich geometric-semantic information in BIM to assist defect mapping and enriches the BIM by industry foundation classes (IFCs)-represented defect information. The defect-enriched BIM facilitates defect management in a data-driven manner. The framework was applied in multiple real-life infrastructure and civil works projects. It demonstrates how the BIM-based D3M framework can enhance the maintenance of those that have been built, and ultimately contribute to a safe and sustainable built environment. Future studies are called for to substantiate each of the 3Ms by leveraging BIM as both an enabler and a beneficiary. [ABSTRACT FROM AUTHOR]

Biomimicry is an interdisciplinary approach to study and transfer principles or mechanisms from nature to solve design challenges, frequently differentiated from other design disciplines by its particular focus on and promise of sustainability. However, in the biomimicry and biologically inspired design literature, there are varying interpretations of how and whether biomimetic designs lead to sustainable outcomes and how sustainability, nature, and mimesis are conceptualised and engaged in practice. This paper takes a particular focus on the built environment and presents a theoretical overview of biomimicry literature spanning across specific fields, namely architecture, philosophy, sustainability and design. We develop upon conceptual considerations in an effort to contribute to the growing calls in the literature for more reflective discussions about the nuanced relationship between biomimicry and sustainability. We further develop a 'Biomimicry for Sustainability' framework that synthesises recent reflective deliberations, as a possible direction for further theorisation of biomimicry, aiming to elaborate on the role of biomimicry as a sustainable design methodology and its potential to cultivate more sustainable human-nature relations. The framework is used as a tool for retrospective analysis, based on literature of completed designs, and as a catalyst for biomimetic design thinking. The objective of this paper is to serve as a point of departure for more active and deeper discussions regarding future biomimetic practice in the context of sustainability and transformational change, particularly within the built environment.

In this paper, we argue that the theory of cultural niche construction provides a cogent and fruitful framework for studying and managing human−environment relationships, including our conceptualizations of them. We first review the development of the ideas of niche construction from evolutionary to social contexts. We then discuss how various human cognitive and affective goals are achieved through our engagement and interaction with the environment, as cognitive and affective niche construction. We extend this analysis to the built environment, as urban niche construction, and provide two examples of urban design for which niche construction provides useful theoretical and practical insights. We also discuss how different urban policy initiatives are related through the lens of cultural niche construction. This paper proposes the theory of cultural niche construction as a framework to conceptualise, model and manage human‐environment relationships towards sustainability. It illustrates how to do these with two cases of urban niche construction. [ABSTRACT FROM AUTHOR]

As the focus on embodied carbon within the built environment has grown in the U.S., local jurisdictional codes have increasingly proposed and implemented code language that requires the use of concrete mixtures that have reduced environmental impacts. This paper provides details about the various ways that localized sustainable concrete provisions have been proposed and implemented in the U.S., including limits on cement content and Global Warming Potential (GWP). These laws and code revisions vary in their measurement of low-carbon concrete and their exemptions and incentives. While the current version of the ACI Building Code, ACI 318-19, does allow for the consideration of sustainability in concrete design, specifics about how the relative sustainability of concrete mixtures and systems are to be measured and compared are not included. This paper addresses how the changing landscape of local jurisdictional codes is driving the development of future ACI 318 provisions to play a part in providing more consistency in the application of sustainable design practices in the United States.

Purpose: This paper aims to draw on an in-depth qualitative case study of an undergraduate sustainability education course to show the extent of pedagogical reflection and teaching capability demonstrated in lived practice to support transformative, systemic and capability building learning processes, as advocated in the literature, for effective sustainability education. Design/methodology/approach: Transformative learning and capability building are an essential part of sustainability education according to the growing body of literature. This approach to education, however, necessitates critical, learner-centred pedagogies which challenge traditional transmissive modes of teaching. Findings: This paper finds that pedagogy which supports the learning experiences and outcomes advocated in sustainability education literature requires significant reflection on behalf of the educator and also motivation, capability and experience to do this, thus more research and academic support is needed which focusses on pedagogical development within sustainability education. Originality/value: Literature on sustainability education often assumes that teachers are capable of reflecting on and transforming their pedagogical practice, and therefore, the pedagogical implications of sustainability education are often understated in research findings. This paper highlights why pedagogical reflection plays a crucial role in the effective implementation of sustainability education. [ABSTRACT FROM AUTHOR]

Multifunctional nature-based solutions (NBS) can help urban areas become more climate proof and adaptable and provide a range of societal goals. Alongside chronic impacts from climate change, the Covid-19 pandemic has illustrated the disruption that unexpected and acute shocks can bring to society. Measures such as NBS can help reduce the vulnerability of urban areas and increase resilience. Traditional infrastructure planning relies on strong business cases to demonstrate the economic value of a scheme. Numerous approaches assign economic value to the benefits from using NBS. However, this value is more than what can be accounted for by traditional finance methods, as there are many different perspectives on 'value'. Decision making processes for selection of NBS measures require stronger integration of these value perspectives. This paper considers these perspectives in the business models that are being used in the decision processes regarding use and selection of NBS. Examples are drawn from case studies in the EU Begin project and also from the Living with Water partnership in the UK, which illustrate how value perspectives can be included in business cases for NBS, also signposting the need to account for potential future changes using scenario planning.

The parametric design applied to the built environment is critical to creating sustainable and resilient spaces. However, this research field involves a vast and complex amount of disconnected information. Therefore, this paper aims to analyse research trends in applying parametric design to optimise sustainability and environmental ergonomics parameters in built environments. The following specific objectives are identified to meet this objective: (i) a quantitative analysis based on a systematic literature review; (ii) a qualitative review based on a performance analysis and scientific mapping; and (iii) a comparative analysis of case studies applying parametric language for the optimisation of sustainability and environmental ergonomics parameters. The 1045 research records covering 1974 to 2021 illustrate a field in development that evolves from early digital advances to climate change adaptations, the circular economy and resilience. It highlights the importance of applying bioclimatic techniques in the built environment, identifying the most optimised measures and encouraging the creation of guidelines to serve as a protocol for future studies, contributing to the existing body of knowledge by highlighting trends, establishing research themes, outlining research networks and suggesting areas for further studies.

The search for new methods and tools to successfully address sustainability challenges is gaining momentum, due to the growing awareness of sustainability issues. Over the past two decades, design thinking (DT) has become a phenomenon in a wide range of contexts, and has recently drawn research attention as an innovative approach for handling complex socioecological problems. This review paper analyzes DT processes covered in sustainable built environment (SBE) articles that focus specifically on DT and innovation, with a view to suggesting/developing an affective new model for sustainability research. The research design was developed following Denyer and Tranfield's method. The author reviewed documents using the evidence from all open access English language articles related to this issue between 2000 and 2022 identified using a Scopus database search in order to clearly identify and analyze the challenges and opportunities for innovation growth in SBE using a DT and innovation framework, 50 articles were selected based on the PRISMA statement and plotted on a modified Ansoff Matrix. This systematic literature review indicates that research regarding DT for innovation in SBE is challenged by the matter of how to identify new contexts and new solutions for future-oriented sustainability. It is also proposed that a wider range of stakeholders are required to help optimize the solutions being generated. The results reveal research gaps in integrating foresight and DT into sustainability research. A model of inclusive foresight design thinking (FDT) is proposed to guide future research to support the practical application and enhance the viability of DT in sustainability.

It is well established that the existing building environmental assessment methods and sustainability assessment methods are intended to foster detailed design stage while there is a need to support early design stages. This research intends to develop a framework that actively supports design development at the formative design stages. The paper reviews the well-established building environmental assessment methods: CASBEE, LEED, BREEAM and GRIHA, and the existing sustainability assessment methods: iiSBE's Sustainable Building Tool (SB Tool), German Sustainable Building Council's Certificate Program (DGNB), Living Building Challenge (LBC) and ARUP's Sustainable Project Assessment Routine SPeAR®. Further, well-known theories of ecological Sustainability are reviewed. The critical points of convergence and divergence of anthropocentric and biocentric approaches are identified to articulate the parameters of sustainability assessment. Specialists in the sustainable built environment assigned weights for assessment parameters (criteria) by applying the analytical hierarchy process (AHP). Their specialist opinions manifest the particular features of the Indian context. The paper delineates the Biocenosis, a novel framework for sustainability assessment of the built environment rooted in the concept of the synergy of nature with social, economic, environmental and cultural benefits for the context of India. It is intended to aid building professionals in the formative design phases as it enables an integrated and comprehensive assessment of the level to which the requirement of a sustainable built environment is satisfied.

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. [ABSTRACT FROM AUTHOR]

This study aims at modelling long-term weather parameters (1955 to 2020), recorded in Bahrain, and at investigating which parameters have strong correlation coefficients with such data to account for mitigation and achieve sustainability. Eight forms of fitting methods were utilized to calculate the correlation coefficient between each parameter versus each given year. These parameters (Average and Anomalies) are the average temperature, maximum temperature, minimum temperature, humidity, wind speed, dust and precipitation. The forms of correlations used are as follows: Linear regression, Quadratic regression, Cubic regression, Power regression, ab-Exponential regression, Logarithmic regression, Hyperbolic regression and Exponential regression. Among all forms of regressions, the Exponential (cubic) regression is found to have the highest correlation coefficient for such data, both Average and Anomalies data; the highest is for humidity versus year (r = 0.900, strong relation), and the least is for precipitation (r = 0.1647, poor relation) for Average data. As for the Anomalies data, the highest is for humidity versus year (r = 0.9019) and the least is for precipitation versus (r = 0.1647, no relation). The novelty of this paper lies in concluding that the exponential (cubic) regression is the most accurate correlation (among 8 correlation coefficients) to predict all the recorded long-term (65 years) weather parameters in Bahrain eight correlation. This regression fit is the most useful one in projecting the weather trend by 2050 in Bahrain to account for the future built environment to become more resilient, sustainable and tolerant with the environment due to the anticipated damage resulting from climate change. More investigation is to be made for other data set in the Gulf Cooperation Countries, and worldwide, to explore whether this Exponential (cubic) regression will still have the highest correlation coefficient among the others.

Featured Application: The Louisiana State University (LSU) Windstorm Impact, Science, and Engineering (WISE) Open-Jet Testing facility is instrumental in enhancing structural resilience under windstorms. The facility represents a Mid-Scale Research Infrastructure to address grand challenges and the need for experimental capabilities in the mid-scale range. Its unique capabilities enable the comprehensive testing and evaluation of critical infrastructure components, encompassing low- and high-rise buildings, photovoltaic (PV) solar panels, wind turbines, bridges, vegetation (nature-based solutions), power transmission lines, and more. Through controlled wind conditions, researchers can gain invaluable insights into the behaviour and performance of these critical infrastructures. The facility is pivotal in advancing the design and engineering of robust, climate-resilient systems capable of withstanding the challenges posed by dynamic environmental conditions. The potential impact of this wind testing facility extends far beyond the boundaries of conventional engineering, offering a pathway towards a more sustainable and resilient built environment on a global scale. Experimental wind engineering is crucial for global structural design. This paper addresses limitations in aerodynamic testing, particularly in wall-bounded and small-scale scenarios. Open-jet testing, introduced as an advanced tool, overcomes turbulence modelling constraints, providing a more accurate representation of real-world conditions. The LSU WISE open-jet facility produces complete turbulence at a large scale, eliminating the need for corrections accompanied by partial turbulence simulation. This discovery holds significant implications in wind engineering and unsteady aerodynamics. Integrating photovoltaic panels with gable-roofed buildings may not require additional structural reinforcement, with a reduction in wind uplift forces by 45–63%. Building-integrated photovoltaics (BIPV) offer design flexibility and aesthetic appeal despite potential higher upfront costs. Strategic interventions, such as design optimization and cost-effective installation methods, can enhance the economic viability of BIPV systems. Contrary to long-held beliefs, the findings challenge the notion that wind loads on structures with sharp corners are insensitive to Reynolds number. Open-jet testing produces higher peak pressures, providing real-world justification for actual damage in high-rise buildings. These results validate the author's hypothesis regarding the underestimation of peak loads (in small-scale testing) leading to cladding failure in high-rise buildings. They emphasize the superiority of large-scale open-jet testing, underscoring its critical role in designing resilient structures. The LSU WISE open-jet facility's unique capabilities hold immense promise for revolutionizing wind engineering, addressing grand challenges, and creating more resilient and sustainable infrastructure. Its applications span critical infrastructure, promising significant economic, societal, and educational impacts in STEM fields. [ABSTRACT FROM AUTHOR]

According to the Global Status report for Buildings and Construction, the building and construction sector accounts for 36% of global energy consumption and 39% of energy-related carbon dioxide (CO2) emissions. Specifically, the construction site represents one of the most significant sources of environmental impact, making it a pivotal element in achieving sustainability within the construction industry. The construction process and maintenance activities on buildings are, therefore, critical phases in which the construction industry is tasked with finding a balance between economic development, social well-being, and environmental protection to ensure a sustainable future for both current and future generations. To promote a construction model focused on environmental, economic, and social sustainability, this paper introduces a Performance Protocol. This protocol serves as an operational tool that allows both the construction company and the contracting authority to manage these aspects throughout the entire construction process. Digital technologies such as BIM and Digital Twin can take advantage of such model to integrate and develop sustainability analysis and simulation during the entire life cycle of a building. The use of digital tools is one of the challenges for the future of the built environment that needs to address not only the issues related to costs and management but also considering the social and environmental aspects of sustainable development.

Housing companies create, maintain and develop an important part of the built environment. Besides their core activity of providing housing, they can increasingly also mitigate societal problems and contribute to social, environmental and financial sustainability. One contribution to sustainability by housing companies is to create meaningful activities for tenants that benefit their employability, skills, careers, and physical and mental wellbeing. These 'activity interventions' are used as a vehicle to create social value. However, it is unclear what sort of impact these interventions have, and how they affect housing companies' financial value. This paper investigates: (1) Swedish housing companies' initiatives to provide meaningful 'activity interventions' for tenants; (2) what value these interventions create; and (3) how social value creation relates to financial value. Observations and interviews (n = 23) with Swedish housing companies are mapped onto a social value creation framework. The findings reveal several types of employment, educational and leisure activities that have been created for tenants, and the areas in which these initiatives create the most social value. Social value creation is often used as risk management to mitigate issues related to criminality, welfaredependent tenants and decreased property values. [ABSTRACT FROM AUTHOR]

Collaboration from multiple stakeholders is a prerequisite to achieve the different goals of a circular economy in the built environment. Gaining the trust of passive householders is a critical factor in housing retrofit at the neighbourhood level, given the aims of the circular economy related to sustainable supply chains, production processes and consumption patterns. Building on notions of trust in expert systems, this paper explores the active roles of providers and householders in personal, technological and institutional trust and whether this can help to implement user-centred circular design approaches in housing retrofit. This study draws on empirical data from Beijing (China) and Amsterdam (the Netherlands). The paper suggests that the active use of providers' and householders' interacting roles at so-called access points in the housing retrofit process could link the practices of households to the different goals of a circular built environment. Building personal trust between constructors, installers, and policymakers as retrofit providers and active householders can contribute to the shared ownership of retrofit housing projects. Enhancing trust in the principles of retrofit packages supports technology optimization through joined product validation via social interactions. Maintaining trust relations that last beyond the retrofit project duration will contribute to future-proof communities. [ABSTRACT FROM AUTHOR]

The urban built environment has a significant role in leading individuals to outdoor spaces, socializing, and being together. Despite the Egyptian Government's efforts to provide more housing for people in different forms, they ignore the social life in the new residential neighborhood when designing the neighborhood's urban form. This paper examines the quantitative connection between the Urban Form Aspects and Social Sustainability in residential communities. The research selects Salam New City in Port Said Governorate as a case study and applies different scenarios for the most important urban aspects. The research uses the simulation method to investigate the effects of the different urban form scenarios on the social aspects by using Urban Modeling Interference (Umi) and DepthmapX simulation software. Finally, the paper concludes that social interaction and activities improve by 48% and social integration will improve by 74% from the base case for Salam New City case study when using the Urban Form Aspects (Green percentage 35%, Mixed land use 40%, Street network 7% with D/H Ratio 4/1), which leads to improving the social life in the selected area.

AbstractWalking, as a transportation mode, not only promotes individual well-being but also contributes to environmental sustainability. Though often neglected in the transport planning process that focuses primarily on motorized transport, the benefits of walking have recently renewed interests to enhance walkability. With the thematic focus on transport planning and network design, this paper first introduces a conceptual bi-level network design framework for enhancing walkability. Following the framework, we then conduct a thematic review focusing on modeling and enhancing walkability through transport planning and design elements. The identified studies are synthesized by answering the systematic classification scheme (SCS) questions. While recognizing the progress that has been achieved by previous studies, we conclude by exposing the challenges that remain and thereafter identifying potential directions for transportation research.

This paper outlines a research project on the use of wood tar as adhesive for architectural stone repairs. Tar was identified as having been used in medieval repair techniques on Stavanger cathedral in Norway, as well as on several other medieval cathedrals in England and Germany. The hypothesis is that a complex adhesive mixture based on wood tar was manufactured and strategically employed by medieval artisans in northern Europe as stone repair material. Given that such repairs have withstood centuries of wear, there must have been extensive material knowledge and awareness of the complex requirements of structural adhesives. These historic tar repairs created the impetus for a research project, the aim of which is to rediscover the lost medieval art of traditional stone repair using wood tar adhesives, recreate the historic adhesive and repurpose it for modern conservation practice. By reintroducing traditional wood tar adhesives based on natural renewable source materials, we could potentially reduce dependence on synthetically manufactured adhesives. Thus, newly-discovered medieval techniques which have successfully lasted centuries will be drawn on to help solve the limited selection of suitable adhesives for stone conservation, contributing to future preservation of stone architecture and the built heritage environment.
