Towards Standardised Environmental Product Data Integration in IFC

Abstract: Whole Building Life Cycle Assessments are currently hindered by manual, labour-intensive workflows and fragmented BIM and LCA data, making iterative use impractical. Existing automated workflows often lack adherence to standards, undermine data quality, or introduce data migration burdens. This study investigates integrating WBLCA data within IFC, focusing on the Danish context, by formalising Danish LCA requirements on bSDD. We propose a data model for implementing EPDs as PDTs, according to ISO 22057, in IFC using the IfcProjectLibrary exchange format defined in ISO 17549-2 and ISO 16757-5. A prototype implementation of PDT-to-IFC conversion tool demonstrates and evaluates the data model’s feasibility.
