Standardization of 7D BIM models for LCA studies: a methodology based on the Level of Information Need

This article proposes a methodology for standardising building information models in Life Cycle Assessment (LCA) studies, leveraging the concept of Level of Information Need. Current integrated BIM-LCA studies often lack robust modelling and information management practices for accurate data extraction. This proposed approach emphasises the model's purpose, translating it into specific information requirements that must be implemented for conducting integrated BIM-LCA studies.
