Solutions: The development of a financing scheme consisting of a combination of innovative tools for standardization, pooling, bundling and de-risking.

Multiple benefits: HousEEnvest project implies greater visibility of the progress that the region is making in the energy improvement of public and private buildings, promoting energy sustainability and driving decarbonization of rural and urban areas of the region [source].

The HousEEnvest project – formed by a consortium of nine partners – follows two years of work between key regional institutions from the energy, economic and building sectors, combined with international resources from IEB and EU cooperation programs, which have allowed designing one financing scheme made to measure of Extremadura building renovation necessities.

Objective – To demonstrate the viability of an innovative financing scheme for the full energy renovation of multifamily houses in Extremadura, which will also contribute to boosting the construction sector.

Solutions – The HousEEnvest project will develop an innovative financing scheme, with a combination of standardization solutions, with funding engineering and de-risking systems, which together breaks the current existing barriers for full energy renovation of multi-family houses in Spain and many others EU countries [source]. Moreover, the project will also focus on the implementation of a Guarantees Fund created with public investment funds, movement of non-refundable grants through the combination of EFSI funds and private participation.

Funding – The funding for this project comes from IEB and EU. In particular, the EU contribution amounts to EUR 631,305 [source].

Success factors – In order to reach a successful project implementation, HousEEnvest gathers today 9 representatives of the entire key actors: decision-makers from the Government, public financial companies, association with access to buildings, associations of the construction sector and companies providing technical, legal and economic expertise [source].

Significant outcomes:

After the completion of the project, the following significant outcomes are expected:

  • To unlock the energy investment in private buildings, using the made to measure Fund [source];
  • To captured untapped high energy efficiency potentials in the energy renovation of Extremadura buildings [source].

Synergies with local policies:

Political alignment:


  • HousEEnvest aims to be a showcase in the unlocking of investment through pooling, when supported by a proper Fund scheme, which can be applied and replicated in other geographies and even other sectors.
