Supporting Europe’s renovation transition
Across Europe, buildings account for a significant share of energy consumption and greenhouse gas emissions. Achieving the EU’s climate objectives therefore requires a large-scale renovation of the existing building stock.
However, building renovation is rarely a straightforward process. Owners often face fragmented information, complex technical decisions, and uncertainty about how to prioritise renovation measures over time. Renovations are frequently carried out in isolated steps rather than following a long-term strategy.
OneClickRENO addresses this challenge by advancing the development and implementation of Building Renovation Passports (BRPs): structured roadmaps that guide building renovation in a staged and strategic way.
The OneClickRENO approach
The project focuses on making Building Renovation Passports practical, usable and scalable across Europe.
To achieve this, OneClickRENO combines technical development, stakeholder collaboration and real-world testing. The project works to define the key elements required to implement renovation passports in practice, including data structures, tools and governance approaches.
A central element of this work is the development of a Building Renovation Passport data model aligned with the revised Energy Performance of Buildings Directive (EPBD). This model supports the consistent generation of renovation passports and facilitates their integration with existing building information systems.
From concept to implementation
Beyond technical development, OneClickRENO explores how renovation passports can function in real contexts. The project tests and refines its approach through pilot activities in Spain, Ireland, the Netherlands, Italy and Greece.
These pilots help examine how Building Renovation Passports interact with national regulatory frameworks, digital tools, building registries and stakeholder ecosystems. The lessons generated provide valuable insights for applying the concept across diverse European contexts.
A collaborative European initiative
OneClickRENO brings together a multidisciplinary consortium including research institutions, technical organisations, digital solution providers and innovation experts.
By combining expertise in building renovation, digital modelling, policy analysis and stakeholder engagement, the consortium works to advance renovation passports as a practical instrument supporting Europe’s transition towards zero-emission buildings.
