What we learn is what we earn from sustainable and circular construction

Sustainable and circular construction entails emissions and wastes reduction through the reuse and recycling of materials to achieve economic gains and save resources for future generations. This work aims to map the academic research on sustainable and circular construction from different imperative angles on the Web of Science (WoS) database. In this line, we classified and reviewed the existing research using a bibliometric and network analysis approach into the following themes: life cycle assessment (LCA), green assessment tools, technologies and methods, quantification of recycling of waste and energy, building information modeling (BIM), greenhouse gas emissions in construction, and greenhouse gas emissions in the specific case of novel construction types. The study provides a bird-eye-view of existing qualitative and quantitative research findings within the themes above. Subsequently, the study highlights the future research avenues within each theme to develop the domain further. The work will assist practitioners and policy-makers in understanding the current status of sustainable and circular construction and suggest necessary actions to attain environmental sustainability.
