BUILD UPON2 proposes to address one of the main barriers stopping proper public management, and consequent upscaling of Deep Energy Efficiency Renovation: the lack of an adequate, widely shared Impact Framework. Buildings are one of the biggest contributors to climate change in Europe and account for over 40% of the EU’s final energy demand and 36% of CO2 emissions. To meet EU’s energy efficiency targets for 2020 and 2030 and long-term goal under the revised EPBD to decarbonise it’s building stock by 2050, renovation becomes crucial, and its rate needs to increase to at least 2-3% per annum. National Renovation Strategies under the EED aimed to accelerate the rate of renovation, however these have not proved effective. The 2018 recast of the EPBD strengthens the role of these Strategies and obliges MS to set out a roadmap to decarbonised building stock by 2050, supported by a suite of measurable progress indicators and milestones. BUILD UPON2 proposes to work with local, national and European stakeholders to create a Multi-Level Renovation Impact Framework that contains a suite of milestones and measurable progress indicators for building renovation strategies, integrating data and insights from the city level. This Framework will serve as a tool for Cities in delivering the EPBD and ensure that local initiatives are aligned with national and European policies. A methodology will be developed to indicate how the Framework reporting system can be integrated into Sustainable Energy Actions Plans (SECAPs), how to use the Framework and how data to support the indicators will be collected and used. The Framework will be tested with 8 pilot cities and the results of this testing phase will be used to update the Framework and create policy recommendations, ensuring that the Framework can be replicated across Europe and help local, regional and national authorities deliver on European energy efficiency goals. The Project Consortium ascertains a successful delivery.
