High upfront costs that district energy retrofitting entails, implies long-term financing schemes. Moreover, multi-private ownership in Spanish residential sector hinders the decision-making process. In the case of CITyFiED project, an innovative business model has been developed between an Energy Services Company and a Building company for Torrelago district renovation. This paper addresses this demo case from a global perspective, identifying the elements of the business case using the Canvas methodology approach and analysing the financing scheme. After a total investment of 16.5 M€, the energy savings achieved enable the payback without increasing the Community fees to the dwellings’ owners.
