iBRoad intended to explore, design, develop and demonstrate the concept of individual building renovation roadmaps (iBRoad), as a tool outlining deep step-by-step renovation plans with customised recommendations for individual buildings (iBRoad-Plan), combined with a repository of building-related information (logbook, iBRoad- Log). The iBRoad approach is an evolution of EPC and energy audit systems, aiming to become a real driver for renovation. The project analysed and built upon relevant examples in Germany, France, and Flanders, to identify the elements, develop an integrated concept, and produce modular tools, suitable for differing national conditions. The iBRoad innovative concept and tools were tested in Bulgaria, Poland, Portugal, and Germany. Field testing followed auditor training and provided auditor and user experience feedback as input to the feasibility and replicability analysis of the model to other building typologies and EU MS. Stakeholder engagement was sought from the start at national (Austria, Belgium, Bulgaria, Germany, Greece, Poland, Portugal, and Sweden) and EU levels, for maximum impact. Throughout the project, communication activities will ensure the concept’s broad dissemination and awareness. iBRoad targeted residential buildings, with a focus on single-family and small multifamily houses.
iBRoad’s implementation, beyond the project duration, will strongly support building owners in step-by-step deep renovation, while avoiding lock-in effects. iBRoad-Plan and iBRoad-Log are expected to empower energy auditors and end-users with knowledge and experience of deep renovation in individual buildings, and to provide public authorities with real-life studies and analysis supporting deep renovation, both for individual buildings and as a long-term national strategy, increasing the renovation rate and depth across the EU.
