The Energy Efficiency Directive (EED) (Directive 2012/27/EU) and the revised Energy Performance Building Directive (EPBD) (Directive 2018/844) both contain technical prescriptions for increasing Europe’s building stock energy performance. However, the greatest challenge to reducing total energy use in buildings lies increasing the renovation rate from the current 1.2 % per year to 3 %, without compromising on quality and effectiveness of technical upgrade measures. One of the main barrier that prevents massive market uptake of renovations is the lack of confidence due the unknown technical and financial risks associated with the process. The perception of risk surrounding building renovation operations is an important driver in most of energy efficiency related financing operations and thus requires through investigation. The EEnvest project (Risk Reduction for Building Energy Efficiency investments), funded under the European Commission Horizon 2020 framework, proposes a combined risk evaluation framework to close the risk awareness and financial gap in the building renovation value chain, providing verified and standardized technical-financial information on a large set of cost and revenue sources related to energy efficiency renovation operations. The main objective of EEnvest project is to secure investors’ trust in energy efficiency actions for existing buildings in commercial sectors, mainstreaming energy efficiency financing thanks to a structured framework for technical and financial risk evaluation. The paper will frame the overall project presenting the preliminary studies regarding the development of a sound and replicable technical risk evaluation framework for energy efficiency actions focusing on the renovation of commercial office buildings.
