Influence of climate on the consumption per dwelling

  • Large variations in climate from one winter to another can influence energy consumption: higher consumption in cold winters and vice versa in mild winters, all other things being equal.
  • Climate corrections provide a measure of consumption that is independent of annual climate variations. These corrections are based on the ratio of actual to normal degree days (i.e. reference degree days*).
  • Energy efficiency indicators should be climate corrected and measured at normal climate.
