DRIVE 0 aims to come to a decarbonization of the EU building stock and to accelerate deep renovation processes by enhancing a consumer centred circular renovation process in order to make deep renovation more attractive for consumers and investors, more environmental friendly.This by combining the need for a circular building industry with the identification of specific local or national drivers to trigger and to motivate end-users for deep renovation, supported by an anthropology based and environmentally friendly approach to make it costumer-centred and respectful of local geo-material areas, by following 4 steps: 1. Developing proven deep renovation products and concepts for example from several recent EU projects, further to circular renovation products and concepts based on local available materials and components, with emphasis on easy to install Plug & Play prefab solutions for envelope elements and building services. 2. Developing attractive consumer centred business models based on circular renovation concepts supported by digitalization and gamification. 3. Providing occupants with attractive and understandable information on total building performances in use. 4.Providing stakeholders evidence of performance of the developed solutions by local study and demonstration cases initiated by ‘local drivers’. The objectives are: 1: To develop proven Plug & Play prefab deep renovation solutions for building elements and building services towards circular renovation products. 2: To provide consumers and potential investors of deep renovation projects with attractive and understandable information of real total performances (energy use, indoor environment and well-being). 3: To demonstrate circular renovation solutions in combination with local drivers in live demonstration cases. 4: To foster new consumer centred business models for circular circular renovation concepts. 5: To roll out the concept on a wider EU scale by involving EU interest groups.

The innovative aspect in Pro-GET-OnE (Proactive synergy for Greater Efficiency On buildings’ Envelopes) consists in the following holistic vision: To combine in a same integrated system based on pre-assembled components the highest performances (iii) in terms of i) Energy requirements – by adding (or substituting the existing with) new prefab and plug and play high energy performing envelopes ii) Safety – by using appropriate steel structures to reduce horizontal loads and implementing the structural safety while supporting the new envelopes (timber for opaque parts/surfaces, glass, PV and solar panels) iii) Social sustainability – by ensuring tailored and customized solutions for users and increase the desirability of retrofit options. Building upon the previous experiences, Pro-GET-OnE aims at promoting a holistic optimized approach that goes beyond the results of EU and national projects and the IEA report on Prefabricated Systems for Low Energy Renovation of Residential Buildings. In fact, PRO-GET-ONE proposes the highest transformation of the existing building’s shell with volumetric increase and buffer zones (i.e. sunspace between the building and the outdoor environment, extra room, etc.). These solutions have been designed and analysed in a large set of existing buildings. Being the openings guaranteed, this solution would efficiently provide an effective zone to reduce thermal losses in the cold winter season while ensuring shadow during summer.
