REuse and REcycling of CDW materials and structures in energy efficient pREfabricated elements for building REfurbishment and construction

RE4 is a collaborative research project of 13 partner institutions from science and industry funded under the European Union’s Horizon 2020 research and innovation programme.

The main purpose of project is to develop a RE4 prefabricated energy-efficient building concept that can be easily assembled and disassembled for future reuse, containing up to 65% in weight of recycled materials from CDW (ranging from 50% for the medium replacement of the mineral fraction, up to 65%). The reusable structures will range from 15-20% for existing buildings to 80-90% for the RE4 prefabricated building concept.

The ACCIONA demopark have been busy recently and we are very happy to share with you that the precast concrete elements and the timber-based facade panel are both safely at the RE4 demo site in Spain! We cannot wait for the mock-up to be finished for everyone to see.

Stay in touch!
