RINNO envisions to deliver a framework solution that will help drastically accelerating the rate of deep renovation in EU building stock reaching an ambitious annual renovation rate of 3.5%. Its ultimate goal is to develop, validate and demonstrate an operational interface with augmented intelligence and an occupant-centered approach that will streamline and facilitate the whole lifecycle of building renovation (planning-design, retrofitting, monitoring). This concept has at its foundation, a set of cost-attractive, environmentally friendly, multi-functional and easily applicable building-related innovations, grouped into: a) plug-n-play, modular building envelope solutions and b) RES, hybrid and storage solutions. RINNO couples the above with innovative retrofitting processes, methods and tools, characterized by low tenants’ disruption. These comprise: efficient (off/on-site) construction strategies, on-the-job AR facilitating environment and multi-stakeholder collaboration, which are expected to shrink the time and cost required for deep renovation, while improving buildings’ performance; all with a short payback period of <4 years on average. The above will be supported businesswise with novel business models aligned with the circular economy principles, enriched with investment de-risking tools and advanced crowd-equity/crowd-lending schemes. RINNO is expected to impact the EU inefficient building stock by a) reaching an ambitious annual renovation rate of 3.5%; b) primary energy savings of 165 GWh/year; c) a reduction of electricity cost by at least 30%; d) a total cost / time reduction in comparison with typical renovation by more than 30% and 40% respectively, and e) an estimated reduction of 40,400 tons CO2-eq/year. RINNO optimized renovation roadmap will be demonstrated at 4 large scale (3,386m2) pilot use cases after being pre-piloted, covering different EU climatic zones and markets of diverse maturity in the renovation sector.
