Climate conditions are taken into account only at local level. Since these climate conditions vary in one particular geographic location over the years, the consumption data have to be corrected. This correction concerns energy consumption for space heating. To apply the correction, the amount of final energy consumption for space heating is multiplied by the weather correction factor.
The weather correction factor does not take into account climatic differences between two different climatic zones. If we want to do this we have to introduce a "climate zone correction factor" which calculates the different indicators on the same number of Degree Days.
Pay attention that no European Benchmarks exist. Benchmarks are always given on a national (or climate zone) level!
