Due to its dynamic nature in construction, benchmarking environmental emissions of road construction projects can be a daunting task. Often stakeholders will have to prioritize the economic and environmental indicators based on the project objectives. The study presents a methodological framework to compare economic and environmental impacts to benchmark sustainable transport construction projects. Through findings, the study aims to inform focus areas and key stages of infrastructure projects to benchmark sustainable performance. Process-based emission and cost estimation models are presented with an AHP based weighting factor that enables prioritization of emissions and costs based on project scopes and objectives. Using a case study, results are represented to validate the framework and methodology. Concrete and steel are identified as the main materials that contribute to total carbon emissions, while soil and gravel are responsible for the highest costs. Electricity consumption is discovered as the major fuel type contributing to carbon emissions. Concrete and dump trucks are discovered as the top two sources of emissions and costs, respectively. Scenario analyses revealed that the choice of equipment significantly affects the project’s emissions and costs. The application of sustainable materials can significantly reduce emissions and cost. The use of the case study approach results in a lack of generalizability. However, the same methodology and process can be adopted for the sustainable benchmarking of different projects. Researchers are encouraged to investigate processes to automate sustainable benchmarking of transport infrastructure construction projects. The study is one of the first attempts to compare cost and environmental impacts using a systematic methodology of transportation infrastructure construction projects.

Energy retrofitting of existing residential buildings has a great potential to achieve a sustainable future. One important way to reach this potential is to understand homeowners’ retrofit behaviors due to their crucial roles in retrofit adoption and retrofit effects. Despite many attempts, researchers and governments still know less about the holistic profile of homeowners’ retrofit behaviors, which brought little success in trigging renovation activities and achieving expected retrofit effects. This study tries to fill this research gap by a comprehensive review of the body of existing research. A keyword-based scientometric analysis was performed based on a set of 152 journal articles. By further refining keywords, main research domains pertaining to investment-decision-energy behaviors, policy instruments, retrofit types, construction & services, and methods & methodologies were mapped to show relevant research knowledge and research topics. Based on these research results, a further integrated framework was developed, which explains homeowners’ retrofit behaviors in a systematic way of cross-disciplinary knowledge interactions. Furthermore, implications for retrofit policies in existing buildings were provided. This study is useful for facilitating future research to deepen homeowners’ retrofit behaviors, and also provides valuable references for policy makers to successfully promote home energy retrofit.

Natural disasters and human-made disasters are threatening urban areas globally. The resilience capacity of the urban system plays an important role in disaster risk response and recovery. Strengthening urban disaster resilience is also fundamental to ensuring sustainable development. Various practices and research for enhancing urban disaster resilience have been carried out worldwide but are yet to be reviewed. Accordingly, this paper gives a scientometric review of urban disaster resilience research by using CiteSpace. The time span (January 2001–January 2021) was selected and divided into three phases based on the number of publications. In addition, according to keyword statistics and clustering results, the collected articles are grouped into four hotspot topics: disaster risk reduction, specific disaster resilience research, resilience assessment, and combination research. The results show that most of the existing research is in the first two categories, and articles in the second and fourth categories both show a high growth rate and could be further research directions. The review indicates that urban disaster resilience is essential for a city’s sustainable development. Moreover, the findings provide scholars a full picture of the existing urban disaster resilience research which can help them identify promising research directions. The findings can also help urban government officials and policymakers review current urban disaster management strategies and make further improvements.

Given the ever-increasing number of aged residential buildings in Hong Kong, green retrofit provides a sustainable solution for improving existing aged residential buildings' performance instead of constructing new buildings. Studies on green retrofit technologies (GRTs) and green retrofit policies (GRPs) have received great attention globally. However, few studies have been done to understand the applicability and importance of GRTs and GRPs, and the impacts of GRPs on the application of GRTs in a particular region, such as Hong Kong. Therefore, based on a questionnaire survey conducted in Hong Kong, this study aims to further examine the GRTs and GRPs that have been identified in a previous study. The applicability of the GRTs and the importance of the GRPs for green retrofit of aged residential buildings in Hong Kong were studies, the correlations between the GRTs and GRPs were analyzed, and a priority guide was developed for promoting green retrofit of aged residential buildings in Hong Kong. The findings can help various stakeholders to have a better understanding of the GRTs and provide valuable references for the local government to develop future GRPs. Furthermore, this study also provides a fundamental guide for future green retrofit research and development in the local and global contexts.

For many decades, safety has been a challenge in the construction sector. Despite extensive efforts to improve overall safety, the sector’s casualty rate still remains high. In practice, dynamic and complex construction processes may lead to on-site risks and safety plans being overlooked, likely leading to a variety of safety accidents. Nowadays, under the guidance of the digital twins (DT) concept, the advent of state-of-the-art sensing and visualisation technologies has offered the possibility to improve construction health and safety in the workplace. To understand the research advances of these technologies, identify their gaps and challenges, and propose solutions to further advance the industry’s safety, we conducted and report a thorough review on the state-of-the-art technological studies, and elaborate upon the key findings in detail. For instance, despite DT being proven to be effective in improving construction workforce safety, the construction industry has yet to fully exploit and streamline these innovations in practice. Overall, this review provides insights into technological clustering, improvement strategies, as well as workforce safety, which can benefit from formulating effective digital technology paradigms.

The World Health Organisation has been working for more than a decade to guide global cities and communities to consider, plan and implement age-friendly places in response to the rapid ageing. In China, promoting age-friendly communities (AFCs) is critical due to the fact of both rapid demographic change and people’s increasing awareness of making preparations to deal with their ageing issues. Although many efforts have been made to promote AFCs in urban China, challenges remain during the construction process. The engagement of stakeholders, budget and policy issues always challenge communities’ pathways to become age-friendly. Simulation as a tool of analysis and prediction can be applied to propose constructing strategies and explore solutions regarding the above concerns. For a multi-agent system that contains several agents, an agent itself may lack resources, information and capabilities in solving the whole problem; however, interactions between each identifiable agent provide aggregated attributes, which can facilitate decision-making procedures afterwards. Therefore, this paper aims to design a multi-agent platform to simulate the briefing stage and explore strategies for promoting AFCs in urban China. The theory and process to develop the platform according to a case study are described; The simulation results and how the platform can help are discussed. This research will serve as a reference for researchers and practitioners to further explore the briefing stage and efficient strategies for promoting AFCs.

The construction industry faces the challenges of balancing environmental concerns with the construction of new buildings. Although the government has identified the promotion of prefabricated construction as an important strategy for tackling this challenge, little attention has been paid by the government to the practical schemes to be used. To fill this gap, a systematic review was conducted of policies related to prefabricated construction in China. In this study, a policy reviewed framework for the prefabricated construction was established. A total of 133 prefabricated construction policies issued from 1956 to 2018 were reviewed by mixed content analysis. The results reveal a closely integrated policy network, the evolution of ambitious policy objectives, and the development of a combination of various policy instruments over the different stages. The most often employed prefabricated construction policy instrument was the standard. Initiatives and guidance were moderately used. The establishment of regulations has been largely ignored in China. In addition, although a diverse range of incentives has been offered, incentives were found to be the least frequently used due to their associated fiscal burdens on governments. Based on our results, a roadmap is proposed for optimizing the existing prefabricated construction policies. The findings of this study increase our understanding of construction policies and how to optimize the existing policies to promote prefabricated construction in China. The study also provides a valuable reference for the large-scale promotion of prefabricated construction in other countries and regions.

Population ageing, together with urbanisation, has become one of the greatest challenges throughout the world in the 21st century. Approximately one million people turn 60 each month worldwide. By 2050, more than 20 per cent of the global population is predicted to be 60 years old or above. Thus, an increasing need is evident for age-friendly communities, services and structures. Numerous studies on age-friendly cities and communities (AFCCs) have been conducted over the past decade. The large volume literature makes it necessary to figure out key areas and the evolution trends of studies on AFCCs. Therefore, this paper aims to provide a comprehensive review of existing literature pertaining to AFCCs. A total of 231 collected publications are analysed and visualised by CiteSpace. According to the keywords and document co-citation networks that are generated, the foundation, hot topics and domains of AFCC research are grouped. Three major themes, namely the characteristics of AFCCs, the application of the World Health Organization's framework in urban and rural areas worldwide, and the measurement of cities’ and communities’ age-friendliness, are identified. In addition, a roadmap of AFCC research is developed. The results of this research will therefore benefit researchers and practitioners.

Green retrofit is an effective way of improving the performance of existing buildings to achieve low energy consumption and low carbon emission. To realize a successful building green retrofit, it is important to understand the barriers and to develop relevant policies for retrofitting existing buildings, especially in developing countries. As a typical developing country, China has a large number of aged buildings with high green retrofit potential. In terms of its government structure, economic development, and building stocks, China is unique in that it poses a unique set of barriers and policy strategies on the promotion of building green retrofit. Based on a critical review, existing retrofit policies in China were reviewed. Then, the barriers to building green retrofit within the context of China were identified. Based on the study of existing policies and barriers, relevant policies for addressing these barriers are recommended. The findings provide a valuable reference for policy makers in China to review current building green retrofit policies or to develop new policies that address the barriers. This study also provides a useful reference for other countries aiming to review their building green retrofit policies.

With an increasing global need for sustainable development, numerous world‐leading construction corporations have devoted significant efforts to implementing sustainable practices. However, few previous studies have shared these valuable experiences in a systematic and quantitative way. RobecoSAM has published The Sustainability Yearbook annually since 2004, which lists the sustainability leaders in various industries, including the construction industry. Learning from those sustainability leaders in the construction industry can provide useful references for construction‐related companies when developing their sustainable development strategies. Based on a comprehensive literature review, this paper identified 51 methods used for improving sustainability performance and 34 outcomes achieved via these methods. These methods and outcomes are used for coding the sustainable practices of sustainability leaders in the construction sector. Using the coding system, 133 annual sustainability reports issued by 22 sustainability leaders (The Sustainability Yearbook, RobecoSAM 2010–2016) in the construction sector were analyzed using content analysis. Social network analysis was then employed to identify the key adopted methods and achieved outcomes (KAMAO) of these leaders. The dynamic trend and regional analysis of KAMAO are also presented. These KAMAO findings provide valuable guidance for international contractors to develop a better understanding of the primary sustainable methods adopted by sustainability leaders in the construction sector and the top outcomes achieved by these leaders. The findings also provide a useful reference for international contractors to evaluate their current sustainability‐related strategies and make improvements.

Green retrofit in existing buildings is of great significance in achieving a sustainable environment. Various policies have been introduced around the world to promote building green retrofit, whereas the uptake is rare for policy ineffectiveness. To improve policy effectiveness, it has been emphasized that a systematic review of existing retrofit policies has a key priority. In this study, a comprehensive review on retrofit policies in China was conducted because there are great application potential for green retrofit in China's existing buildings. This study examined the state-of-the-art development of retrofit policies during 1996–2019 and explored policy characteristics based on content analysis. The ambitious retrofit objectives and multiple retrofit instruments were identified. The relevant policy instruments can be grouped into six categories, including command and control, economic incentives, technology, information, certification, organization & professional. The most cited policy was the command and control instrument, followed by the certification-based instrument. Moreover, policy instruments related to economic incentives, technology and information were also valued by the China government, while the government attempted to reduce the adoption of economic incentives and technology measures since 2010. In addition, organization & professional instruments are largely ignored in China. In the light of these findings, a roadmap was proposed to enhance the effectiveness of building retrofit policies. This study sheds lights on the effectiveness of China's building policies to accelerate the popularity of green retrofit, and provides valuable references for other countries and regions to shape their own policy pathways towards the large-scale promotion of building green retrofit.

Urban infrastructures commonly include four types of functional infrastructures: traditional infrastructures, greenspace infrastructures, water infrastructures, and connective infrastructures. They work as an integrated system for supporting sustainable urban development. It is therefore important for having a proper method to help understand whether there is a balance between functional urban infrastructures' carrying capacities (FUICC). This paper introduces an alternative model named FUICC Catastrophe Model (FCM) to evaluate the balance of carrying capacity between various urban infrastructures. The development of the model FCM adopts Mean-Variance Analysis (MVA) technique and Catastrophe Progression Method (CPM) collectively. The application of FCM is demonstrated by using the empirical data collected from 35 cities in China. The research findings suggest that: 1) the difference in carrying capacity of each functional infrastructure between the sample cities is significant; 2) the difference in the degree of balance between FUICC is also significant between the sample cities; 3) the sample cities are classified into four categories, namely, acceptably balanced, less balanced, poorly balanced, and unbalanced. 4) the balance performance between FUICC among Chinese cities is characterized with polarization; 5) the balance performance of carrying capacity between functional urban infrastructures is generally poor in China, 40% of the sample cities achieving acceptable performance.

Purpose This study aims to identify senior citizens’ requirements related to “embedded retirement facilities (ERFs)”, which are small-scale, multi-functional and community-based care facilities for senior citizens in mainland China, and to discuss whether senior citizens’ perceptions are influenced by their backgrounds. Design/methodology/approach A questionnaire type of research was administrated to gain senior citizens’ rankings of services that should be provided by ERFs. Non-parametric statistical models were applied to analyse the collected data. Findings Results reveal that health care services for senior citizens are considered the most important. Requirements regarding rehabilitation and entertainment and daily life assistance are ranked second and third, respectively. Culture-related activities are the least important. Differences in the senior citizens’ background also influence their choices. Research limitations/implications This research is based on a questionnaire survey completed in northeast China. Opinions from other areas of mainland China will be collected in the future study. Furthermore, the key items identified in this research, which was completed by participants from the built environment discipline, can be further elaborated by combining interdisciplinary feedback. Practical implications This study explores services that are supposedly provided by ERFs. Findings will provide useful perceptions from senior citizens and will enable decision makers to prioritise services for senior citizens. Social implications Although senior citizens are the end users of ERFs, their needs are easily overlooked. This study calls attention to their needs from ERFs, and the results are likely to serve as references for stakeholders in building improved facilities. Originality/value ERFs have been provided in mainland China to cater to senior citizens’ needs since 2014. However, few studies have identified senior citizens’ requirements for provided services. The survey-based results of this work will serve as references for various stakeholders in making enhanced decisions.

Public–private partnerships (PPPs) have been increasingly adopted in China. Sustainability of PPPs has become a priority for a sustainable development of PPPs. Most prior studies focus on sustainable implementation of PPP projects. Few research efforts have been done to examine the impacts of PPPs to sustainability from an external perspective and a more macro geographical scale. Meanwhile, the social aspect of the sustainability of PPPs has not been widely studied. Therefore, this study aims to propose a social sustainability contribution evaluation system (SSCES) for PPPs to evaluate PPPs' contribution to regional social sustainability at the institutional level. An indicator system of the SSCES for PPPs was developed, which included 8 requirements for socially sustainable development and 33 social sustainability indicators. The weights of indicators were determined by using the analytic hierarchy process method. The results indicate that, in the context of China, promoting people‐oriented urbanization in PPPs can help enhance regional social sustainability. This study provides a useful evaluation tool for various stakeholders to evaluate the sustainability of PPPs from an institutional level, especially for local governments to review current PPP polices and make improvements.

Building green retrofit is considered as an effective means of energy saving and achieving sustainable development goals. The success of a building retrofit is highly dependent on the retrofit strategies used. However, it remains challenging to select appropriate retrofit strategies for a specific retrofit building. There are numerous cases of building retrofit around the world, which can be collected, stored, and analysed. The knowledge gained from these cases could provide a useful reference for making decisions on new retrofitting projects. This study presents a case-based reasoning (CBR) approach to support building green retrofit decisions. A total of 71 retrofit cases in China were collected. The attributes of the retrofitting buildings were identified, including the general building information, component information, and energy and cost information. A synthetic optimisation weighting method was adopted based on both expert opinion and the attribute characteristics. A real retrofit case located in Shanghai was used as a case study to demonstrate the application of the CBR approach. The results indicate that the CBR approach can aid in identifying similar cases from the case database, and extracting valuable information from these. The experience and lessons learned from past cases can guide decision makers in making improved decisions on new green retrofit projects.

Due to global climate change, carbon reduction has become a critical issue for the construction industry. Low carbon building has been adopted as a strategic objective, and its implementation demonstrates the enormous potential of reducing carbon emissions. Despite much research, some important research areas or gaps have not been identified, while simultaneously, few studies describe the knowledge roadmap for low carbon building research necessary to guide scholars and practitioners. The purpose in this paper is to provide a comprehensive and objective analysis of research areas regarding low carbon building using the scientometrics method. A total of 378 low carbon building-related publications were reviewed. Based on the keyword co-word analysis, document co-citation analysis and clustering analysis, the results show that 100 research keywords, 3 research hotspots and 5 research domains are extremely important for the advancement of low carbon building. Based on the in-depth analysis of the findings, the knowledge structure with different prominences was developed, which grouped LCB research into five themes and various sub-topics. Significantly, this paper provides the knowledge roadmap needed to facilitate further research and applications for both academia and industry stakeholders to improve low carbon building.

Environmental quality in public rail transit has recently raised great concern, with more attention paid to underground subway microenvironment. This research aimed to provide guidance for healthy urban subway microenvironments (sub-MEs) according to comprehensive micro-environmental categories, including thermal environment, air quality, lighting environment, and acoustic environment from both practical and regulation perspectives. Field sampling experiments were conducted in Nanjing Metro Line X (NMLX). Descriptive analysis, correlation analysis and one-way analysis of variance were used to investigate the status quo of urban sub-MEs. A paired samples t-test was then performed to compare among subway station halls, platforms, and in-cabin trains based on integrated sub-MEs. Results show that relative humidity, air velocity, respirable particulate matter (PM10) concentration, and illuminance dissatisfy the requirements in relevant national standards. Significant difference was observed in lighting environment between station hall and platform. It was detected platforms are warmer and more polluted than train cabins. Additionally, subway trains generate main noise on platform which is much louder when leaving than arriving. Protective strategies for sub-ME improvement as well as principles for updating standards were proposed from a proactive point of view. The findings are beneficial for moving towards healthy urban sub-MEs and more sustainable operation of subway systems.

In the past decades, unprecedented dramatic economic development in the Chinese cities has also brought serious environmental problems. In line with this, the Chinese government has been investing great efforts and resources in addressing environmental problems. However, little previous studies have been conducted in examining whether this development is efficient from a win-win perspective balance between economic growth and environmental protection. This paper presents a comprehensive analysis on the environmental efficiency (EE) in the process of dramatic economic development in the Chinese cities. The Super-slack-based measure (Super-SBM) model is adopted to analyze the EE performance. Data used for analysis are collected from 283 sample cities in China. The research results indicate that the overall EE performance across the Chinese cities is relatively low, and the differences in EE performance among the 283 cities are significant. The top three EE performers are Shenzhen, Sanya and Erdos, and Baiyin, Xinzhou and Liupanshui are the bottom three performers. The results also suggest that the EE performance in the Eastern area, where most first-tier cities are located in, is significantly higher than that in the Central and Western areas (aggregated with fourth and fifth tier-cities). From the dynamic perspective, the results show that China has achieved significant improvement in environmental efficiency across the surveyed period of 2003–2016. The research findings provide valuable references not only for the Chinese policy-makers and practitioners to adopt measures for promoting a win-win balance between environmental protection and economic development in the Chinese context, but also for further studies on environmental efficiency in the international context.

Despite great efforts being devoted to, and substantial resources being consumed by low‐carbon economy (LCE) development globally, it appears that little is known about whether LCE development is efficient. This paper measures low‐carbon economy efficiency (LCEE) performance from a global perspective. The Super‐slack‐based measure model is adopted to analyse the LCEE performance of 115 sample countries during 1999–2013. The Malmquist Productivity Index is used to evaluate the dynamic change of LCEE between sample countries. The results indicate that overall worldwide LCEE performance is at low levels, and the differences in LCEE performance among the 115 sample countries are significant. It also indicates that LCEE performance is generally better in developed countries. From the dynamic perspective, a significant improvement in LCEE performance was achieved globally during the survey period, with an overall annual increase of 0.75%. These results provide a valuable reference to policy‐makers and practitioners for adopting measures to promote LCE development effectively at a global level.
