Influence of climate on the consumption per dwelling

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