Building Understanding
for a Shared Renovation Plan
RenoVisor is an EU-funded Horizon Europe project supporting citizens,
homeowners and energy communities in making informed renovation decisions.
By combining social science, advanced building simulation and participatory advisory tools, RenoVisor aims to increase the building renovation rate and contribute to Europe’s decarbonisation goals.
The Challenge
Meeting EU climate and energy efficiency targets requires a major increase in building renovations. However, renovation decisions are often slowed down by limited access to clear and comparable information, complex technical and financial trade-offs, and difficulties in collective decision-making, especially in condominiums.
The RenoVisor Approach
RenoVisor addresses these barriers by developing three user-friendly tools that combine building simulations with behavioural and social insights, support individual and collective decision processes, and make renovation impacts, costs and benefits understandable to non-experts.
Tools that will be developed within the project
Single-Family House: support for homeowners
Multi-Family House: support for condominium decision-making
Energy Communities: support for districts and neighbourhoods
All tools consider technical, financial and social aspects and support multi-stage renovation planning following the efficiency-first principle.
Key Features
- Co-created with citizens and energy communities
- Accessible to non-experts and useful for professionals
- Cost, financing and payback estimates
- Climate-resilience and comfort insights
- Support for consensus-building and energy communities
- Focus on inclusion and reduction of energy and mobility poverty

RenoVisor partners gather in Thurles for an interactive third project meeting
From co-creating digital tools to preparing for real-world testing, during 29 September to 1 October 2026, the RenoVisor consortium held its third project meeting in Thurles, Ireland, to review progress, exchange ideas and define strategic planning.
Co-creating in RenoVisor: Putting Participation at the Heart of Design
Renovating a home is not only a technical or financial decision. It is a process shaped by people’s priorities, knowledge, concerns, expectations and everyday lives.
Overcoming NIMBY for a Fair Energy Transition
As Europe accelerates its clean energy shift, local opposition - often called NIMBY ("Not In My Backyard") - frequently halts vital green developments. Within RenoVisor, our team is studying why local resistance occurs and how to solve it and here, in particular, how...
Where does an energy community begin? Not with technology, but with a shared story
You have lived here for years. You know your neighbours, greet each other in the street and feel at home in this neighbourhood. But your energy bills keep rising, and you find yourself wondering: how can we create an affordable and sustainable future together? This...
Citizen-led renovation: the missing link to Europe’s renovation goals
Across Europe, millions of homes need to become more energy efficient to meet the EU's climate and energy objectives. Yet many households still struggle to start renovating due to uncertainty, a lack of reliable information and the complexity of the process. Why...
Digital Help for Scaling Citizen-Led Renovation: the RenoVisor Tools may Help RenoCOOP Partners in Achieving their Goals, and vice versa
At a consortium meeting held in Lisbon at the end of June, members of Goiener–a partner in both projects–presented the RenoVisor Single-Family House (SFH) tool mock-up to the rest of the RenoCOOP consortium.
Citizens Help Shape the RenoVisor Renovation Tool
As part of the RenoVisor project’s co-creation process, EcoVision recently completed a series of engagement activities aimed at ensuring the RenoVisor Single Family Home (SFH) tool is designed around the real needs of its future users.
FEBEA presents financing options for building renovation in Ireland
The RenoVisor partner has carried out a mapping of the subsidies and loan schemes available in the Irish pilot to contribute to the development of the RenoVisor Single Family Home tool, which will be first launched in Ireland.
How communication helps turn RenoVisor’s Research into real impact
When discussing European research and innovation projects, attention is often focused on technological developments, scientific findings or innovative digital tools. However, another element is equally important for ensuring long-term impact: communication and dissemination.
A Visual-thinking workshop explores how to integrate vulnerable groups in RenoVisor
Organised by COMILLAS within the Vulnerability Task Force, the session explored how vulnerable people can be better identified, engaged and supported through RenoVisor’s renovation tools and pilot activities.
Pilots and Impact
The tools will be tested in over 10,000 households in Ireland, Spain and the Netherlands, generating practical insights for scalable renovation solutions across Europe.
