Review on building renovation passport schemes and related initiatives
The building renovation passport (BRP) is an instrument that provides a long-term, step-by-step renovation roadmap for specific buildings. Article19a of the Energy Performance of Buildings Directive (EPBD) (2010/31/EU), requires the European Commission to conduct a feasibility study clarifying the “possibilities and timeline to introduce an optional building renovation passport that is complementary to the energy performance certificates, in order to provide a long-term, step-by-step renovation roadmap for a specific building based on quality criteria, following an energy audit, and outlining relevant measures and renovations that could improve the energy performance”. The objective of the feasibility study is to explore a spectrum of policy options and to evaluate their potential impact at EU-level.
This report, the first of three deliverables, comprises a review of existing BRPs and similar initiatives. The review includes BRP schemes that largely correspond to the definition in Article 19a, including the German renovation roadmap (individueller Sanierungsfahrplan) and the Flemish renovation roadmap and logbook (EPC+ and Woningpas), as well as schemes and initiatives that share some characteristics and objectives with the BRP, like one-stop-shops, energy performance certificates, energy audit frameworks and online renovation advice tools.
The review covers 28 European and 5 non-European schemes and delivers some valuable insights. The 16 most relevant schemes were analysed in more depth and featured as “deep dives”. The most successful initiatives have combined renovation advice with financial support, legal requirements and/or communication campaigns. The review shows that to be effective the BRP should be integrated with and reinforced by other elements (e.g. simple access/use, financial support, communication).
BRPs are effective in alleviating two of the main barriers to renovation: low awareness of the benefits of energy renovation and insufficient knowledge of what measures to implement and in which order. The analysis confirms that tailored renovation advice, together with other support measures, has an impact on the decision to renovate, the number of measures to implement, the performance level of the selected measures, as well as the type of measures implemented.
The conversion rate describes the process of a potential owners actually investing in an energy renovation: first, building owners must be convinced to get a BRP and once they have it, they must decide to invest in energy renovations. The conversion rate from four different one-stop-shops analysed in this report is 10.8% (percent of building owners receiving the first contact who will go on and finally invest in an energy renovation). The conversion rate depends on several aspects, such as available subsidies, how complicated the renovation process is or is perceived, and quality of communication (user-friendly webiste, likeability of energy expert etc.).
The two most common elements among the deep dives are “tailored renovation advice” (14 out of 16) and “integrated financial possibilities” (7 out of 16). These initiatives share the belief that for building owners interested in renovation finding the right information is time-consuming and it is difficult to make informed choices about the combination of renovation measures, especially in the long-term. The second common point is that aggregating and streamlining financial support (grants and loans) is required to make long-term solutions (i.e. deep renovations) viable and attractive.
Financial constraint is the main reason for people not to renovate and the explanation to why the innovative one-stop-shops analysed in this report have not conducted more than 100-1,800 deep renovations each. Financial constraints are also the main reason why building owners choose less efficient solutions, hampering the long-term transition to a highly efficient and decarbonised building stock. The review also shows that targeted renovation advice is needed to better align the direction of private investments with the long-term vision for the building stock.
Finally, the schemes and initiatives considered in this study do not target any hard-to-reach groups (not interested, low-income etc.) and don’t include indoor environmental quality (improved air quality, noise reduction and sufficient lighting) or the environmental benefits of renovations, even if comfort is often used as a marketing point.
Analysis of the relevance, feasibility and possible scope of measures at EU level for building renovation passports
The report comprises an analysis of the relevance and feasibility of introducing optional building renovation passports, and an investigation of the possible scope for additional measures for introducing a building renovation passport at EU level. The report also outlines six policy options for the EU to consider, on which the impact analysis in the last deliverable will be based.
This report has been prepared as part of a study commissioned and supervised by the European Commission’s (EC) Directorate-General for Energy. It is intended to provide technical support about the feasibility of introducing an optional building renovation passport in the European Union (EU). This work is carried out in close consultation with stakeholders and in collaboration with leading experts in the field. As part of the consultation process, a first stakeholder meeting was organised in June 2019, and a second meeting is planned for November 2019 where the content and suggestions in this report will be discussed.
Selection of policy options for building renovation passports and analysis of related potential impacts
Six policy packages were developed and defined, ranging from leaving the BRP development and implementation fully to the Member States to introducing it as a legal requirement in the next EPBD revision. Each package outlines a potential policy approach to the BRP. Based on BPIE’s impact assessment model, a thorough analysis of the potential impacts of each policy option until 2050 was carried out. The analysis used logic models to estimate the causal links between potential policy packages and their effects in terms of number of BRPs, renovation rate and depth and other impacts. The six packages are described as follows:
- Option 1: Member States decide whether to design and implement a BRP scheme (soft)
- Option 2: Member States decide whether to design and implement a BRP scheme (stringent)
- Option 3: The EU introduces a common reference framework (soft)
- Option 4: The EU introduces a common reference framework which includes minimum energy efficiency requirements for renovation (stringent)
- Option 5: A BRP scheme is incorporated as a requirement under the EPBD (soft)
- Option 6: A BRP scheme is incorporated as a requirement under the EPBD (stringent)
The impact analysis provides an estimation of the impact of each policy package on:
All the policy packages are expected to trigger considerable energy and CO2 emission savings. Final energy demand is expected to fall by an additional 8-9% by 2050 as a result of policy packages 5 and 6, amounting to almost 300 TWh per year. The estimated final energy demand savings for non-residential buildings range between 6-8% in policy packages 4, 5 and 6, amounting to around 130 TWh per year. CO2 emissions are estimated to be reduced by between 16 and 43 million tonnes per year for all buildings.
