The goal of this project, “Aggregation and improved governance for untapping residential energy efficiency potential in the Basque Country-AGREE”, is to drive investments in modernising energy efficiency of private residential buildings in the Basque Country, by means of developing and deploying innovative mechanisms to trigger demand and aggregation, better governance and tailored financing solutions. The Basque Government’s Housing Ministry, working closely with three Basque cities (Donostia-San Sebastián, Vitoria-Gasteiz and Basauri), IHOBE (Technical Secretariat of the Basque Network of Sustainable Municipalities – Udalsarea 2030) and Tecnalia will co-design and implement innovative solutions to modernise residential buildings dating from 1940-80, both from the perspective of energy efficiency (façade) and of accessibility (installing lifts) in 3 pilot projects. This will involve an investment of approximately €8.5 million and will lead to a reduction of 250 tons of CO2e/year from now until 2022.
