Building renovation passports: Customised roadmaps towards deep renovation and better homes

01 Nov 2016

The European Union is facing a double challenge: increasing building renovation rates while aiming at achieving “deep renovations”. Increasing the current EU renovation rate from 1.2% per annum to 2-3% is essential to meet both the EU 2020 targets and the commitment undertaken in Paris in December 2015. About 75% of the EU's 210 million buildings are not energy efficient, and 75% to 85% of them will still be in use in 2050. Ensuring a highly-efficient and fully decarbonised building stock by 2050 is a major challenge. The quality of the energy renovation of our building stock is, therefore, of paramount importance. Despite the proven economic and technical feasibility of building renovation, and despite the societal and environmental benefits it could bring, renovation rates are still low and considerably below the expected level. Building owners and potential investors face multiple barriers to improve the energy performance of their buildings. Together with difficulty to access finance, one of the most often quoted barriers is the lack of knowledge about what to do, where to start, and which measures to implement in which order.
The aim of this report is to provide an overview of initiatives currently developed: three of them were selected, in Flanders, France and Germany, all revolving around the concept of “building renovation roadmap or passport”. These initiatives were chosen for their advanced phase of development (they will soon enter the implementation phase), as they provide a good overview of the process supporting the creation of a Building Renovation Passport and as they cover the main issues that need to be addressed for its development and implementation. In the three cases, public authorities have shown interest for this concept (France) and have supported or driven (Flanders and Germany) its development.
