    abstract = {{A} major fraction of building materials is transformed into waste at the end of a building's life cycle. {F}or sustainability reasons, it is of importance to maintain or recycle urban stocks, and in consequence to minimise the use of primary resources, wherefore a {M}aterial {P}assport ({M}{P}) represents an important support-tool. {A} {M}{P} acts as a design optimisation tool, as well as an inventory of all materials embedded in a building and displays the recycling potential and environmental impact of buildings. {I}n this paper, the proof of concept for a {M}{P} is demonstrated on a use case, which is a residential building, whereby a variant in timber and a variant in concrete construction are evaluated. {R}esults show that the recycling potential of the concrete variant is better; however, concrete leads to more waste, due to its significantly higher mass in comparison with timber. {T}he comparison of the environmental impact of the variants shows, that the variant in timber has a significantly lower impact to the environment, than the variant in concrete. {R}esults also show that the {M}{P}-methodology has large potentials for improving the recyclability of new buildings as well as for making assumptions for upcoming materials through displaying embedded materials of existing buildings.},
