Structural Data: Non-domestic building
Non-domestic buildings are used more than half for non-domestic purposes (StaBu IV C5).
One important tool to help categorise non-domestic buildings is the Bauwerkszuordnungskatalog (Bogenstätter 2007). This catalogue classifies residential and non-domestic buildings as well as service/technical buildings according to their type of use. Nine different types of usage form the basic classification. Other levels of categorisation are subdivided into primary and secondary groups (see illustration below).
In official statistical reports on the building sector (standard evaluation, StaBu o. J.), non-domestic buildings are classified into eight types. These are: institutional buildings, office and administrative buildings, agricultural service buildings, factories and workshops, retail and storage buildings, hotels and restaurants, other non-agricultural service buildings as well as other non-domestic buildings (see illustration below).
This classification is adopted here. Eight different types of non-domestic building form the basic level of classification. They are specified according to the type of usage. These non-domestic buildings are generated in two different ways. On the one hand, so-called synthetic average buildings are determined using data on objects of the same usage in the BKI building databank (Gruhler, Deilmann 2015; Deilmann et al. 2015; Gruhler, Deilmann 2017; Schiller et al. 2015; Schiller et al. 2016). On the other hand, concrete representative buildings are calculated using construction documentation. The generated non-domestic buildings can be employed in diverse studies to represent our built physical environment (Ortlepp, Gruhler, Schiller 2016a; Ortlepp et al. 2017; Schiller, Gruhler, Ortlepp 2017; Schiller, Müller, Ortlepp 2016).
Non-domestic buildings classified by form of use
Institutional buildings are those whose primary purpose is not as dwellings. They are used to accommodate and cater for certain person for non-residential purposes (for example medical treatment or convalescence) (StaBu IV V5, StaBu 1978).
Institutional buildings include: hospitals, care homes (institutional buildings for the integration and care of the disabled; nursing homes for the elderly and the ill); homes for infants, young children and teenagers; children’s homes; convalescent homes for young mothers; holiday and recreation homes; homes belonging to educational institutions, barracks and emergency services as well as other institutional buildings (StaBu IV V5, StaBu 1978).

Agricultural service buildings are non-domestic buildings primarily dedicated to the following sectors: market gardening, farming, forestry, animal husbandry and fisheries. They are used, for example, for storage or to house animals, machines, tools as well as intermediate and end products of agricultural and forestry enterprises (StaBu IV V5, StaBu 1978). Such buildings can be agricultural halls, cattle/pig sheds, barns or greenhouses.

Factory and workshop buildings are non-domestic buildings directly related to the extraction and distribution of energy and water, or to the production and repair of goods, or to the removal of waste (StaBu IV V5, StaBu 1978).
Factory and workshop buildings include: workshop buildings belonging to the police, to border protection agencies, fire brigades and civil protection agencies; buildings for energy production and distribution; buildings for water collection and distribution; buildings for sewage removal; buildings for waste removal; abattoirs as well as other factory and workshop buildings (StaBu IV V5, StaBu 1978). These are, for example, workshop buildings, machine or pump houses, factory buildings, production halls or assembly halls.
