Europe’s building stock, which includes both residential and commercial buildings, is responsible for nearly half of the EU's primary energy consumption and more than a third of its CO2 emissions. The EU-funded RINNO project aims to facilitate deep renovation of the building stock by addressing major technical and socio-economic barriers. It offers a portfolio of innovative technologies, improved processes supported by an on-line platform and software tools, as well as new business models. RINNO is expected to improve the EU’s inefficient building stock by capturing 0.2 % of the renovation market and deliver primary energy savings of 165 GWh/year; total cost reductions of 30 %, a time reduction of 20 % and carbon savings of 40 400 tons CO2-eq/year. RINNO’s renovation roadmap is demonstrated at four large-scale (3 386m2) pilots.
RINNO envisions delivering a framework solution that will help dramatically accelerate 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:

    ▪ Plug-n-play, modular building envelope solutions.
    ▪ 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 are 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:

   ▪ Reaching an ambitious annual renovation rate of 3.5%.
   ▪ Primary energy savings of 165 GWh/year.
   ▪ A reduction of electricity cost by at least 30%.
   ▪ A total cost / time reduction in comparison with typical renovation by more than 30% and 40% respectively.
   ▪ An estimated reduction of 40,400 tons CO2-eq/year.

RINNO optimized renovation roadmap is 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.
