Started in 2016, this project arises from the need to have effective design tools that are easy to access and use, which make it possible to implement energy saving measures, use of renewable energies and clean, safe and efficient heating and cooling sources in the different Autonomous Communities of Spain and of the companies that make up this “RehabilitaGeoSol”, and to obtain a “marketable end product” that can be exported to other Autonomous Communities, as well as to different countries, making the internationalization of the companies and organizations involved viable, allowing a great technological and business development for this Consortium, and consequently for the economy of the regions and the country. The Project “REHABILITAGEOSOL. Energy efficiency through rehabilitation, sun and geothermal energy” (RTC-2016-5004-3) is a project financed by the State Programme for Research, Development and Innovation geared to the Challenges of Society, within the framework of the State Plan for Scientific and Technical Research and Innovation 2013-2016 of the State Research Agency (Ministry of Economy, Industry and Competitiveness), co-financed with ERDF funds.
