Robust and Reliable technology concepts and business models for triggering deep Renovation of Residential buildings in EU

4RinEU is a Horizon 2020 EU-funded project involving 13 partners that seeks to provide new tools and strategies to encourage large scale renovation of existing buildings, fostering the use of renewable energies, and providing reliable business models to support their applications. 4RinEU has the aim to define robust, cost-effective, tailorable deep renovation technology packages supported by usable methodologies, feeding into reliable business models. The project will minimize failures in design and implementation, manage different stages of the deep renovation process, from the preliminary audit up to the end-of-life, and provide information on energy, comfort, users’ impact, and investment performance.
