Integrating Environmental and Circularity Criteria for Construction Product Selection: A TOPSIS-Based Approach Using the French INIES Database

In a context marked by the transition toward circular economy (CE) strategies and increasingly stringent environmental regulations, selecting appropriate construction products during the design phase remains a major challenge. Despite advances in life-cycle assessment (LCA) studies and multicriteria decision analysis (MCDA) methods for sustainable construction material selection, the systematic screening and ranking of construction products based on national environmental databases and product-level circularity attributes remain insufficiently explored. This study proposes a data-driven framework based on French Environmental Product Declarations (EPDs) from the INIES database, structured according to RE2020 construction categories. The methodology combines circularity-related and environmental impact criteria within a TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) model. Two case studies are analyzed under several weighting scenarios reflecting different decision priorities. The results show that some alternatives maintain relatively stable rankings across different scenarios, while others exhibit variations depending on criterion weights. These findings highlight the influence of decision-makers’ preferences on product selection processes and the importance of considering both environmental and circularity dimensions in assessments. Overall, the proposed framework provides a structured approach to support construction product selection in the French context and contributes to integrating circularity considerations at the product level.
