Before 1 January 2012, the Commission, in accordance with the procedure referred to in Article 16(2), shall raise the percentage of harmonised bottom-up calculations used in the harmonised calculation model referred to in point 1 of Annex IV, without prejudice to those Member State schemes that already use a higher percentage. The new harmonised calculation model with a significantly higher percentage of bottom-up calculations shall first be used as from 1 January 2012. Wherever practicable and possible, the measurement of total savings over the total period of application of the Directive shall use this harmonised calculation model, without prejudice to those Member State schemes that use a higher percentage of bottom-up calculations.
