Residential buildings are buildings that serve residential purposes for at least half of the total usable floor space (Destatis 2022). Various aspects can be used to differentiate between residential buildings (Destatis 2014). Here, residential buildings are subdivided according to use and size into single-family houses (SFH; with one or two flats) and multi-family houses (MFH; with three or more flats). A further subdivision is made on the basis of the age of the building. The selected building age groups correspond to those of the housing stock statistics (Destatis 2020).
The single-family and multi-family buildings shown here are so-called synthetic buildings. They are aggregated, respectively, from a certain number of buildings with similar characteristics. Their composition is documented.
Material contents are calculated for the buildings differentiated according to building elements, material groups, raw materials; waste categories as well as grey emissions. The calculated material composition indicators can be used and downloaded to answer a wide range of questions related to resource conservation and climate protection.
