A BIM-based approach for multi-objective optimization of sustainable materials selection through life cycle analysis

Abstract Given the increasing need for design coupled with constrained financial resources, a comprehensive approach that combines life cycle assessment (LCA), life cycle cost analysis (LCCA), and multi-dimensional optimization was suggested to develop a decision-making framework for cost-effective buildings. The proposed framework considers various aspects such as performance, economic considerations, and environmental factors. Integrating environmental and economic analysis into building construction and design was explored, emphasizing the use of Building Information Modeling (BIM) to manage building data and conduct cost and environmental assessments. Finally, a framework was suggested for selecting optimal materials for pre-construction activities. The study also highlights the importance of considering sustainability and long-term costs in decision-making. In addition, the integration of economic aspects into sustainability assessments was discussed, and challenges and areas for future research were identified. The research methodology included creating a comprehensive database, utilizing life cycle assessment software, and employing optimization techniques to select the most suitable materials for different regions. The results showed significant differences with more than 50% reduction in cost evaluation between generic and optimal materials in the life cycle assessment. In the doors category in North America, greenhouse gas production was reduced by 47%, which was observed between the United States and Australia.
