In the case of deep renovation of buildings, energy savings are usually not sufficient to repay the investment and operational cost in a time that is acceptable to Energy Performance Contracting (EPC) providers (e.g. Energy Service Companies (ESCOs)) and third-party financers. Therefore, such projects often need some grant support to make operations financially viable. Cohesion Policy funding can combine grants and financial instruments to support EPC. This factsheet summarises the key points and solutions discussed on this topic during the fi-compass workshop organised as part of the Member State specific support on 6 December 2022 in Warsaw, Poland. The takeaways from the workshop are largely applicable also in other Member States and relevant for different building types, including public, commercially used or multi-apartment residential buildings.
