Federal Buildings
The federal government set new standards for the energy-efficient construction of administrative buildings. The new buildings, constructed for the relocation of parts of the federal government to Berlin in 1999, use 20% to 50% less energy than is required by the recent Thermal Insulation Ordinance. The figures are 44% for the Federal Chancellery, 34% for the Federal Ministry of Economics and 29% for the Office of the Federal President.
