In order to ensure the broad applicability, 4RinEU approach and technologies will be completely implemented in 3 Demo-Cases and tested with 3 Early Adopter Buildings.

The 3 Demo-Cases owners are both private and public agencies managing an important social housing building stock in three EU-countries:


Even though these agencies renovate buildings with an annual rates around 2%, usually the renovation targets are quite low and far from current best practices, mainly because lack of affordable renovation strategies compatible with the available economic resources.

In addition, the strategy for renovation is driven by maintenance, safety and accessibility issues, level of satisfaction of the users without taking into account the cost-effectiveness of the solutions. In this regards, the technology renovation packages, the methodologies and the business models developed within 4RinEU have the great potential to define more effective deep renovation strategies increasing the cost-effectiveness of the solutions allowing to enhance the annual renovation rate of the building stock managed by the involved agencies.

Spain - Agència de l’Habitatge de Catalunya


The spanish Demo-Case is a multi-family building with four floors and 24 dwellings (average surface around 45 m2).

Although the building is quite new, it presents high primary energy consumption. In fact, it was built during the construction bubble with poor standards and low quality. Accordingly, it represents a strategic case study for the renovation with a high replication potential for the social housing building stock in Spain.

The building belongs to the Catalan Government and it is managed by AHC, Agència de l’Habitatge de Catalunya (Housing Agency of Catalonia).
