This conceptual paper aims to develop a theoretical framework for carbon trading in the built environment through theories to expand current knowledge on components of carbon trading systems.

This theoretical framework was developed and supported with existing theories and past empirical literature from built environment, economics and finance. Underlying theories used in the framework were selected due to their significance and applicability to carbon trading projects. Hypotheses set in the study summarise the propositions developed from the theories and past empirical literature.

The framework reveals four major components of carbon trading for the built environment. Six hypotheses were further proposed to unravel the resultant influence of their interactions on each component in the trading system.

This paper sought to undertake a theoretical review of classical theories and past studies on carbon trading. Even though a systematic review was undertaken, the constructs in the theoretical framework may not be exhaustive.

This study contributes and advances the body of knowledge on the components that comprise the mechanism of how carbon trading operates in the built environment. Theoretically, the framework developed serves as a multi-dimensional guide on the operations of carbon trading in the built environment.

The theoretical framework developed endeavours to consolidate multi-faceted theories from varying disciplines on the components that comprise carbon trading in the built environment.

The implementation of smart maintenance (SM) has greatly benefited facility managers, construction project managers and other stakeholders within the built environment. Unfortunately, its actualization for stakeholders in the built environment in the fourth industrial revolution (4IR) era remains a challenge. To reduce the challenge, this study aims at conducting a bibliometric analysis to unearth the critical success factors supporting SM implementation. The future direction and practice of SM in the construction industry were also explored.

A bibliometric approach was adopted for reviewing articles extracted from the Scopus database. Keywords such as (“smart maintenance“) OR (“intelligent maintenance”) OR (“technological maintenance”) OR (“automated maintenance”) OR (“computerized maintenance”) were used to extract articles from the Scopus database. The studies were restricted between 2006 and 2021 to capture the 4IR era. The initial extracted papers were 1,048; however, 288 papers were selected and analysed using VOSviewer software.

The findings revealed that the critical success factors supporting the implementation of SM in the 4IR era are collaboration, digital twin design, energy management system and decentralized data management system. Regarding the future practice of SM in the 4IR era, it was also revealed that SM is possible to evolve into maintenance 4.0. This will support the autonomous maintenance of infrastructures in the built environment.

The use of a single database contributed to the limitation of the findings from this study.

Despite the limitations, the findings of this study contributed to practice and research by providing stakeholders in the built environment with the direction of SM practice.

Stakeholders in the built environment have clamoured to implement SM in the 4IR era. This study provided the critical success factors for adopting SM, guaranteeing the 4IR era. It also provides the research trends and direction of SM practice.

In urban planning, sustainability is closely linked to the quality of urban public spaces (UPS). However, some UPS encounter issues of low attractiveness and underutilisation. Vitality serves as a crucial measure in this context. The research perspective on the vitality of UPS centres on the balance between human activities and the built environment. Therefore, this article aims to systematically review critical aspects of UPS vitality evaluation system, including research objects, vitality components and research methods, from the dimensions of crowd activity and the built environment.

A systematic literature review using PRISMA analysed English-language publications from 2008 to 2023 in Scopus and Web of Science (WOS) databases, employing keywords related to UPS and vitality, with defined inclusion and exclusion criteria.

(1) Research objects, including parks, squares, waterfronts, blocks and streets. (2) The factors contributing to crowd activity characteristics originate from five dimensions, namely spatial, temporal, visitor, activity and feedback. Environmental factors, both external (accessibility, surrounding function mix and population density) and internal (service facility mix and water presence), significantly impact vitality. (3) The study primarily relies on quantitative data, including traditional surveys and emerging significant data sources like dynamic location and traffic, social media, geospatial and point of interest (POI) data. Data analysis methods commonly used include correlation analysis and comprehensive evaluation techniques.

The findings contribute to a comprehensive understanding of the vitality evaluation system for UPS from multiple perspectives for urban planners, aiding in identifying key factors and research methods in the vitality evaluation of various types of UPS.

The purpose of this paper is to conduct a critical analysis of the commonly projected visions on the future of built environment, focusing on transformative research. The primary question is will the construction sector be able to make the projected transformative leap even if the history of technology adoption in construction suggests otherwise? And, what role can academic research play?

This paper is based on a reflective research and qualitative review of academic articles, white papers and reported projections for the future of construction. The reflections are based on discussions with colleagues and students, including thought experiments.

There is a general agreement across various sources about the key technical and social drivers for the future of construction. However, these projections seem to be emanating from industry insiders, and more diversity and creativity is needed in exploring alternative possibilities.

The paper should be useful for researchers in assessing their research strategy, especially those aiming to focus on the future of construction and transformative research. The findings of this paper suggest the need for collaboration and explorations with diverse disciplines, including those that may not appear immediately connected to digital construction.

The paper should be useful for individuals and organizations, especially start-ups that are seeking novel opportunities to disrupt the future of construction.

The originality and value of this research lies in a timely critique of the commonly projected trends in the future of digital construction. The use of reflective research and thought experiments emphasizes the need for divergent thinking and creative research methods in construction research.

This study aims to review the status quo, current state of research, research hot themes and research gaps in sustainable facilities management (SFM) in the built environment (BE) through an extant literature review.

To map and analyze knowledge paths in the context of SFM research, a sequential explanatory mixed-method review involving bibliometric and content analysis was used to help identify current research trends, research hot themes and knowledge gaps. The Scopus search engine was used to find 169 relevant articles. For a better understanding of the literature accumulated, a bibliometric analysis was carried out by using VOSviewer to reveal current research themes, the status quo and current state of research as well as research gaps.

Through the literature review and content analysis, the current research themes on SFM revealed from the study include green building technologies, assessment methods of SFM, smart buildings and building information modeling. The research hot themes in SFM include smart buildings and green building technologies, green buildings (GB), architectural and building designs in the university sector, assessment methods in buildings and decision-making and the adoption of asset and facility management in the university sector. Indoor air pollution, intelligent buildings, climate change, maintenance, environmental management, facilities, historic preservation, environmental performance, energy management, etc. are the research gaps identified from the study, and these serve as potential areas for future research studies under SFM. It was recognized that facilities managers are increasingly involved with sustainability policies within their organizations and are developing sustainability agendas to keep up with the changing nature of the facilities management (FM) profession.

The findings of this study hold relevance to the FM practice, as the integration of SFM by facilities managers can lead to waste reduction, decreased operating expenses and reduced energy consumption. In addition, occupants of sustainable buildings experience improved conditions that contribute to better health and productivity, thus boosting their overall well-being. Consistent with the themes of smart buildings and green technologies, revealed to be the hot themes in the SFM research scope, properties with sustainable features can command higher rental rates and property values, appealing to a broader range of stakeholders. SFM practices in universities can aid in saving money from reduced facility operational costs and improve the image of institutions while creating better indoor environments for students and staff. The analyses of countries involved in research can open doors for the establishment of research groups and the development of collaboration between universities in different countries researching similar topics of interest.

The geographical scope of this study is not limited and, therefore, encourages broad applicability of the findings to the global sustainable BE.

Circular building adaptability (CBA) in adaptive reuse – building transformation – projects can facilitate a resource-efficient and futureproof redevelopment of the built environment. However, there has been a lack of practical tools that guide practitioners on how to foster CBA in adaptive reuse. Therefore, this study aims to collaboratively develop a guiding framework for CBA in adaptive reuse (CBA-AR) projects in general. The CBA-AR framework is a descriptive and content-oriented synthesis mapping a series of strategies to the CBA determinants alongside their enablers and inhibitors.

A participatory research-oriented approach was followed. First, an archival research was conducted to develop the CBA-AR framework based on literature review and case studies. Second, two co-creation workshops, triangulated with structured interviews, were conducted to validate and expand the framework.

The first version of the CBA-AR framework comprises 30 CBA strategies. It also brings seven enablers and six inhibitors together with the 30 CBA strategies. The outcomes of the participatory approach contributed to refining and expanding the framework. The final of the CBA-AR framework version comprises CBA 33 strategies. This version brings 10 enablers and 7 inhibitors together with the 33 strategies.

This framework can be used as a guiding and reporting instrument by designers and property developers while transforming vacant or obsolete properties in the Netherlands. Policy makers can refer to this framework and amend adaptive reuse legislation.

The CBA-AR framework can introduce a transformative change in theory and practice, as it is based on theoretical, empirical and participatory research.

Facilities management (FM) organizations are pivotal in enhancing the resilience of buildings against climate change impacts. While existing research delves into the adoption of digital technologies by FM organizations, there exists a gap regarding the specific utilization of artificial intelligence (AI) to address climate challenges. This study aims to investigate the drivers and barriers influencing the adoption and utilization of AI by South African FM organizations in mitigating climate change challenges.

This study focuses on South Africa, a developing nation grappling with climate change’s ramifications on its infrastructure. Through a combination of systematic literature review and an online questionnaire survey, data was collected from representatives of 85 professionally registered FM organizations in South Africa. Analysis methods employed include content analysis, Relative Importance Index (RII), and Total Interpretative Structural Modeling (TISM).

The findings reveal that regulatory compliance and a responsible supply chain serve as critical drivers for AI adoption among South African FM organizations. Conversely, policy constraints and South Africa’s energy crisis emerge as major barriers to AI adoption in combating climate change challenges within the FM sector.

This study contributes to existing knowledge by bridging the gap in understanding how AI technologies are utilized by FM organizations to address climate challenges, particularly in the context of a developing nation like South Africa. The research findings aim to inform policymakers on fostering a conducive environment for FM organizations to harness AI in fostering climate resilience in built assets.

Studies show that the twenty-first-century construction industry needs reskilling and upskilling tools to train large numbers of the workforce for better-integrated project delivery. Evidence shows that digitisation via the fourth industrial revolution (4IR) technology can play a critical role in reskilling and competency demand. Attempting to use digital technology may have had some challenges. Studies about the perceived hindrances facing Nigeria's built environment professionals (BEP) reskilling and upskilling needs in the workplace via 4IR technologies are scarce. Thus, the study investigated the perceived encumbrances facing Nigeria's BEP training needs and proffered measures to improve their performance in the workplace via 4IR technologies.

The researchers engaged BEP in Lagos and Abuja, Nigeria. Regarding the data collection, a qualitative research design was adopted. The study achieved saturation after 32 virtual interviews. A thematic analysis was adopted for the collected data.

The study shows that using 4IR for reskilling and upskilling will enhance integrated project delivery. But the level of usage in training needs is low. Findings identified the various ways reskilling and upskilling could be achieved. Also identified are the major built environment areas that require 4IR training. Findings highlighted possible encumbrances facing the use of 4IR technologies by Nigerian BEP for reskilling and upskilling needs in the workplace and proffered feasible measures to improve 4IR usage for training needs.

The study is restricted to the perceived encumbrances and proffers measures to improve BEP reskilling and upskilling needs via 4IR technologies via a qualitative method. Future research is required to validate the findings and test the proposed framework that emerged from the study.

The study confirms that reskilling and upskilling measures are required at all skill levels and may lead to economic growth. The paper would advance Nigerian higher educational accreditation agencies and various BEP regulatory bodies to review the curriculum and incorporate 4IR as a component or module.

The thematic network analysis and proposed framework could be utilised to stimulate Nigeria's BEP reskilling and upskilling needs in the workplace via 4IR technologies. It would stir main stakeholders, especially government policymakers, to facilitate programmes to improve 4IR technologies usage.

In order to determine whether the factors affecting office worker well-being are location dependent, this exploratory study analyses the relative importance of different “building well-being” factors for prime office workers in two leading but environmentally contrastive real estate markets: London and Hong Kong.

This paper adopts a mixed methods sequential explanatory design (follow-up explanations model), consisting of three phases: an exploratory phase to refine the building well-being factors, a quantitative phase utilising a questionnaire to assess the relative importance of these building well-being factors (N = 281: London = 171; Hong Kong = 110), followed by a final phase of follow-up interviews with respondents to explore the reasons behind the significant differences observed in the quantitative phase (N = 13: London = 7; Hong Kong = 6).

While London and Hong Kong share some highly-ranking factors in common, significant differences in importance are observed for 17 of the 31 identified factors as a result of contrasting physical, economic, and cultural environments.

Despite growing recognition of the importance of the built environment on well-being, to the authors’ knowledge there has been no previous research investigating how building well-being demands may vary systematically across geographies. Understanding these differences has important implications for interpreting building well-being research, effective business operations, real estate investment, building certification scheme design, and governance of the built environment.

This study aims to support the global initiatives that advocate for ensuring healthy lives and promoting well-being for everyone, regardless of age, while allowing people to stay at their homes as long as they desire. The built environment (BE) plays a crucial role in achieving this, but in some countries, such as the UK, the housing stock has been found to require extensive adaptations to support resident’s health and well-being. While much research has been done on care provisions and later living housing, these solutions are unsuitable for low-population density areas (LPDAs).

The study is encompassed by investigations around a systematic product development guided by the Double-Diamond Design Framework. This research focused on the “Discovery” phase, which involved online in-depth interviews, incorporating elements from the Human-Activity-Space-Technology Model, supplemented by an interactive board to discover key activities, elements and actors involved in supporting strategies for ageing in place.

This paper presents strategies to help people age in place, focusing on LPDAs. The interventions identified in this paper encompass fundamental elements such as layout design and smart home technologies.

The results provide contextualised BE interventions applicable to creating age-friendly communities, focusing on house design and service delivery from a product design approach.
