The DRIVE 0 project deals with the promotion of strategies for the decarbonisation of the existing building stock through the implementation of deep renovation interventions. The project aims at promoting the adoption of a circular approach in renovation processes that, in order to be attractive and effective, must be based on the customer’s actual needs. According to the DRIVE 0 approach, circular retrofitting is based on the use of energy from renewable sources and the use of materials from biological or technical cycles, in which waste production is minimised and end-of-life strategies with a positive impact on the environment are envisaged.
