The integration of BIM in the application of green building materials in construction projects

In recent years, with the growing call for sustainable development, green building materials, which are of great meaning for reducing resource and environmental impacts, have attracted more and more attention. However, in China, a country with frequent construction activities and high resource consumption, the application of green building materials in construction projects still faces challenges. Building Information Modelling (BIM) as an emerging technology in the construction industry can increase the adoption rate of green building materials in construction projects. The aim of this study is to identify the barriers encountered in the application of green building materials in Chinese construction projects, and to propose corresponding improvement measures by integrating BIM in the decision making. This study adapted a qualitative research method, using semi-structured interviews as a research tool. A total of 6 respondents (including project managers, architects, engineers, and researchers) from Chinese construction companies and research institutions collected interview data, and used Nvivo software to analyze and summarize. The results of this study show that although the application of green building materials in construction projects in China still faces challenges, including market acceptance and supply chain issues, cost and economic feasibility issues, and lack of relevant technology and knowledge. In addition, the study found that BIM technology made a great contribution in promoting the application of green building materials. Through BIM technology, the whole life cycle information management such as material selection, engineering simulation and performance evaluation of construction projects can be carried out, so as to improve the application of green building materials. By exploring the obstacles to the application of green building materials in China’s construction projects and combining with the promotion of BIM technology, this study puts forward a series of specific suggestions and solutions to foster the application of green building materials. This research has made certain theoretical and practical contributions to foster the application of green building materials for the sustainable development of China's construction industry.
