Material Cadastre of Buildings in Germany 2022 (matcad2022, adm2022)

EN: The dataset provides building material indicators for the German building stock in 2022. This includes the quantities of building materials and their global warming potential for 44 and 11 material groups, respectively. The results are provided as geodata (GeoPackage) on the level of buildings, administrative units (time status: 2022), and geogrid.

The data were calculated at building polygon level using the "3D Building Metrics Germany 2022" (3DBM-DE). This data set is derived from the official "3D building models for Germany in Level of Detail 2" (LoD2-DE) and provides building footprint geometries with geometric attributes.

Methodical background is a building typology approach that is used for a characterization of the building stock in order to summarize buildings with comparable geometric patterns, building constructions, and structural characteristics, providing the interlinkage to the type-related building material indicators. For this purpose, we use the building function, derived by the 3D building dataset (LoD2-DE), to differentiate the non-residential building stock and a complex geometric approach to differentiate residential buildings in single-/two-family and multi-family houses.

When using the data, it should be noted that ––due to the type-based approach–– the information provided on the individual buildings will differ significantly from the materials actually used in the building. Targeted data aggregation of the building-related dataset is essential for a meaningful and appropriate interpretation of the data.
