Formalizing Information for Disassembly Potenttial of Buildings Using BIM and Labeled Property Graphs

Abstract: Building circularity assessments aim to reduce waste and primary material demand. Indicators like the disassembly potential (DP) assess the detachability of elements and layers, but Building Information Modeling (BIM) lacks sufficiently detailed DP information in early design stages. Key information, such as connection types between elements and components, is missing in open BIM formats such as Industry Foundation Classes (IFC). To address this, we propose a new method using labeled property graphs to represent component-specific archetypes based on BIM. Tested in a case study, this approach enhances assessments of DP, providing designers with improved insights for early-stage circularity decisions.
