MAKING THE RESULTS OF BOTTOM-UP ENERGY SAVINGS COMPARABLE

The Energy Service Directive has pushed forward the issue of energy savings calculations without clarifying the methodological basis. Savings achieved in the Member States are calculated with rather non-transparent and hardly compara- ble Bottom-up methods. This paper develops the idea of parallel evaluation tracks separating the Member States' issue of Energy Service Directive verifica- tion and comparable savings calculations. Comparability is ensured by develop- ing a standardised Bottom-up calculation kernel for different energy efficiency improvement actions which simultaneously depicts the different calculation op- tions in a structured way (e. g. baseline definition, system boundaries, double counting). Due to the heterogeneity of Bottom-up calculations the approach re- quires a central database where Member States feed in input data on Bottom-up actions according to a predefined structure. The paper demonstrates the pro- posed approach including a concrete example of application.
