Material passport

A digital tool that provides information about the material composition of buildings and the quality and quantity of the materials they contain. This has multiple uses and benefits: as a planning and optimization tool to support efficient use of materials in the construction and later disassembly of buildings, to document details of the materials for later recycling and recovery at the end of the building’s useful life, and as a basis for the creation of a material inventory at the municipal level (cf. urban mining). In addition, new digital planning tools such as Building Information Modeling (BIM) can be used to create a digital material passport and manage the data over the entire lifecycle of a building.
