“…Her collaborative publications with Jaime Solís-Guzmán and Alba-Rodríguez, who also make the top list of authors, might have contributed to her high impact record [26,27]. Vivian Tam and Guomin Zhang are the other two top authors who have made significant research contributions since 2019 to the environmental impacts at the construction stage of buildings [28][29][30][31][32][33][34][35][36]. This includes both construction materials and impacts on the construction-activity level.…”

The building-and-construction industry has been researched extensively over its life cycle regarding green and sustainable processes and techniques due to its major contributions towards energy consumption and its environmental impacts. Over the past decade, the construction stage of a building is often criticized for overlooking or approximating the environmental impacts as compared to other life-cycle stages of a building. This is evident through strong research findings regarding other building life-cycle stages in building-emission-assessment studies. With the drive towards digitization, the construction industry is receiving significant research attention in order to minimize environmental impacts at the construction stage. Despite these research initiatives, only a handful of recent review studies have systematically furnished current advances, gaps and future directions in environmentally sustainable building-construction techniques. The current study represents a systematic literature review of the environmental impacts at the building-construction stage with the objective of identifying the current findings, gaps and future research scopes. A bibliometric assessment revealed key author contributions, key research areas and collaboration aspects of research works related to environmental impacts of construction in building projects. Four major barriers and knowledge gaps in conducting a comprehensive assessment at the construction stage of a building were identified, including the lack of definition of a generic system boundary, difficulties in data collection, complex modeling issues and complications in the classification and analysis of emissions. The findings would provide key knowledge for passionate construction-industry stakeholders who are keen to benchmark green and sustainable construction practices in the building industry.

“…According to the promotion effect of different policies on green retrofit technology, Tan et al (2021) further divided the six green retrofit policies into three priorities. Among them, direction-based policies, financial support policies and knowledge and information policies are policies at tier one.…”

The carbon-intensive economy has dramatically caused global climate changes and profoundly impacted humankind. As one of the largest energy consumers, carbon emissions in the construction industry (CECI) play a crucial role in achieving the carbon neutrality goal. Government behaviors could significantly affect CECI. However, few studies have comprehensively reviewed existing literature regarding the effect of government instruments on triggering carbon reduction. A total of 1,082 papers about CECI from 51 countries/regions were retrieved in this study, while 296 relevant articles on the government behaviors in CECI were collected to conduct further analysis. Based on the bibliometric analysis with CiteSpace, the co-occurrence networks of countries/regions, institutions, keywords and cluster analysis are applied to illustrate the characteristics of previous studies. Furthermore, a research framework has been formulated to review the impact of government behaviors on CECI during the life cycle of buildings. The result indicated that government behaviors could affect CECI through three stages, i.e., material production, construction and operation, which is considered the transmission path of government behaviors towards CECI. Moreover, the findings revealed that government behaviors present the most significant impact on CECI in the following sectors: 1) the green supply chain management and waste recycling in the material production stage; 2) the green building decisions and the adoption of off-site construction in the construction stage; 3) energy conservation behaviors and green retrofit decisions in the operation stage. Finally, this study discusses prior study gaps and provides potential directions for future research.

“…The official energy efficiency departments in the surveyed nations have made great efforts to enforce a mix of different RPIs. These instruments can assist in improving stakeholders' retrofit awareness, knowledge, and skills and provide retrofit guidelines and supports for them [22,40].…”

“…Retrofit policies vary significantly since political structures, social milieu, economic and environmental factors, and existing building stocks are heterogeneous in different countries. In addition, the benefits of retrofit policies, such as carbon emission reductions, are quite subjective, depending on policy implementation pathways [40]. Despite a number of studies on retrofit policies, there are still several research gaps, which can be summarized as following: (1) ambiguous relationship between different kinds of RPIs and stakeholders; (2) unclear common obstacles observed in multiple countries to the uptake of retrofit schemes; (3) a lack of a roadmap for the penetration of retrofit schemes in the residential sector.…”
