The annual supervision of larger buildings (more than 1,500 square metres) is carried out by between 500 and 700 specially trained consultants. About 25,000 buildings are concerned. Every month all buildings, except industrial buildings, and those with very low energy consumption, with a surface of more than 1,500 square metres must register their consumption of heat, electricity and water. Once a year, a consultant makes an audit comprising an Energy Label and an Energy Plan. The Energy Label evaluates the consumption of heat, electricity and water on scales from A to M (A is best) in comparison with average figures for comparable buildings. The Energy Plan informs the building owner about relevant measures for energy saving in the short and long run.
