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