Methodology:
For households, the ODEX is carried out at the level of 3 end-uses (heating, water heating, cooking) and 5 large appliances (refrigerators, freezers, washing machines, dishwashers and TVs)
For each end-use, the following indicators are considered to measure efficiency progress:
- Heating: unit consumption per m2 at normal climate (toe/m2)
- Water heating: unit consumption per dwelling with water heating
- Cooking: unit consumption per dwelling
- Large electrical appliances: specific electricity consumption, in kWh/year /appliance
The variation of the weighted index of the unit consumption between t-1 and t is defined as follows:
It – 1/It
with UC i: unit consumption index of end uses i
and ECi: share of each end-use i in total consumption.
The value at year t can be derived from the value at the previous year by reversing the calculation: It /It -1= 1/( It -1/It),
ODEX is set at 100 for a reference year and successive values are then derived for each year t by the value of ODEX at year t-1 multiplied by It /It -1.
