This report has been conducted by the European Commission’s Joint Research Centre on behalf of DG Energy with the objective to evaluate the practices in place in the different EU Member States regarding the provisions to collect, store and assess the information arising from Energy Audits and how these are being used to track performance. The report is also looking into how Member States are assuring the monitoring and verification in the period after the realization of the mandatory energy audits. The report gives an overview of the different practices in place by the Member and an outline of the barriers identified by Member States both when collecting the information of Audits and in the monitoring and verification stages. This report was put together by sending a survey to energy efficiency experts in the Member States, from Energy Agencies, Ministries responsible for the implementation and regulation of energy policies, academia and ESCO representatives during the period from June to October 2017. It was possible to gather contributions from contact points from the great majority of the EU 28 Member States except from the cases of Luxembourg and Poland. The main findings of the report are that, overall, Member States are, in its bigger part, collecting and storing the information from audits in databases, being through web templates or functional mailboxes, receiving the totality of the audits reports. Some of the barriers being pointed out by experts are the difficulty to evaluate the great amount of data from audits and the lack of dedicated templates for companies to fill out with audits information. There are already several Member States performing verification and monitoring activities built on the first audits received, but the majority of them are still not using the data available in monitoring and verification activities.
