Emerging results

At the submission of its second interim report, the EEFIG working group collecting and monitoring data on energy efficiency investments and financing across EU Member States and targeted economic sectors finds itself on-track, and yet still grappling with an imperfect and complex environment. The Working Group has 23 members from 18 institutions and counts on an additional 41 observers. 

Having passed the midpoint of its work, the working group has identified most of the EU data sources which provide either insights into energy efficiency or investment data in the target sectors (Buildings, Industry and SMEs). It has also identified a 12-point set of principles used by The Basel Committee on Banking Supervision (BCBS - paper number 239) for the sound aggregation of risk data in banks. While BCBS 239 was introduced after the financial crisis in 2009 to deal with severe data-related shortcomings within financial institutions, the WG feels that its frame can be adapted to energy efficiency investment data challenges and in its interim report provides the Commission a sense of how this might work. 

In a huge effort to identify and review against BCBS 239 a significant amount of relevant data sets across on Energy Efficiency data were assessed, the WG believes that there is no single data set that could immediately be adapted for the purpose of measuring energy efficiency investments. However, this second interim report outlines the general framework to use for the final methodology recommendations.  

In addition, the WG has identified the appropriate use of modelling, estimation, AI and machine learning to fill the many gaps identified, as well as incoherence between the multiple datasets reviewed with respect of providing a full picture. IEA and EIB methods to develop and backtest different ways to use surveys and experts to hypothecate and bridge data gaps is highly educational and over seven years these distinct and complementary methods have been continuously developed.
