VDI 3807 Blatt 2:2014-11

This standard applies to the use of characteristic energy and water consumption values for buildings supplied with heating energy, electrical energy and water, especially where values for individual buildings are compared to the averages and standard values given in this standard. The values given in this standard are based on measurements of consumption during the years 2004 and 2005 in Germany. Where characteristic energy and water consumptions of buildings in other countries are compared to the standard values given in this standard, the boundary conditions to be applied in those countries (standards for thermal insulation, climate, typical use) must be taken into consideration.
