Research Database Nonresidential Buildings


For the first time in Germany the nonresidential building sector will be object of a representative sample survey on status and dynamics of structural parameters, energetic quality and decision making processes in refurbishment. Geoinformatic methods will be applied to define the sampling frame for the so far unknown population of nonresidential buildings. The ground would methodologically be prepared for a periodic and cost-efficient monitoring of the building sector.

Work plan

  • Provision of the sampling frame for a sampling survey by geoinformatic methods based on a national database of official building footprints supplemented by secondary attributes (IÖR)
  • Screening of basic building characteristics of up to 100.000 buildings (BUW-ÖPB), derivation of basic structures of the German nonresidential building sector
  • Interviews in up to 10.000 nonresidential buildings on structural data, status and dynamics of thermal insulation measures, technical installations of buildings as well as on proprietors and their facility management habits (professional market research institution)
  • In-depth-interviews in up to 1.000 buildings on energy consumption, simplified energy demand calculations (by specialized energy consultants), derivation of significant partial characteristic energy values, calibration of calculated demand and measured consumption
  • a) Analysis and scenarios on the building stock’s development towards the energy and climate protection goals and its relevance to the economy in Germany
  • b) Further development of geoinformatic methods towards morphological typologies of nonresidential buildings
