Social Energy Renovations (SER) project stimulates sustainable renovation in the third sector. SER intends to design, set up, and implement an innovative de-risking financing mechanism that entails financing and technical standardisation, project aggregation, social impact assessment and credit enhancement. Under SER’s financing scheme, an ESCO raises low-cost long-term capital via a financing instrument integrated with a de-risking mechanism. The investment is repaid via long-term service contracts signed between an ESCO and a building owner. As a result of SER, social enterprises gain access to affordable sustainable renovations, coupled with technical assistance, while investors gain access to secure, high impact investments aligned with ESG and impact investment criteria.
