Monitoring and evaluation of energy savings from domesticappliances for the EU’s Energy Service Directive

A crucial prerequisite for the successful implementation of the Energy Service Directive (ESD) is the availability of harmonised calculation methods for the energy savings achieved. Such methods will enable the Member States to prove that they attain the overall target of 9 % or more energy savings by 2016. Since 2006, the project “Evaluation and Monitoring for the EU Directive on Energy End-Use Efficiency and Energy Services EMEEES”, implemented under the European Commission’s Intelligent Energy Europe programme by 21 partners and co-ordinated by the Wuppertal Institute, has worked on a set of 20 bottom-up and 14 top-down evaluation methods. It developed (1) an integrated system of bottom-up and top-down methods for the evaluation of energy services and other energy efficiency improvement measures; and (2) a set of harmonised default values for the methods. The paper presents an overview of the final results on EMEEES’ methods for domestic space and water heating, including solar water heating, white goods, and IT equipment. It discusses the importance of measurement for the effectiveness of the ESD, looking at the quantity to be measured – all or additional energy savings – and early action. It compares the main elements of calculation needed to ensure consistent results between bottom-up and top-down methods. It also includes preliminary results from field tests of some of the developed methods. Finally, general conclusions are drawn.
