The Buildings Performance Institute Europe has recently published a report that reviews the plans of three regions in Europe to introduce buildings renovation passports (BRP). To meet long-term energy savings objectives, policymakers are actively trying to do two things: increase the percentage of buildings being renovated annually and to increase the level of ambition of those renovations. Will the BRP succeed where other instruments have failed? Will the BRP fill the gap that an Energy Performance Certificate leaves? Is there sufficient advice to the consumer from a BPR to take the decision to renovate? It is too early to say but there are some interesting pilots and planning that will try to make a difference.
The BPIE explores the plans (since none is fully implemented yet) in one region of France, in the Flanders region of Belgium and in Germany. There is no single definition of a building “passport” (well, there is no common definition of a deep renovation either) but the BPIE study looks at some of the common elements. The report defines the passport: “A Building Renovation Passport is defined as a document – in electronic or paper format – outlining a long-term (up to 15 or 20 years) step-by-step renovation roadmap for a specific building, resulting from an on-site energy audit fulfilling specific quality criteria and indicators established during the design phase and in dialogue with building owners.” Thus, importantly, the passport follows a staged renovation plan for a specific building in a comprehensive manner.
The following diagram shows the elements for the development of a building renovation passport.
The report details the three case studies, showing the approaches they are taking. This is well developed and will help readers follow the design process to better understand why certain approaches were taken.
The report comes to some important conclusions and recommendations for developing a BRP. It outlines five guiding principles: long-term perspective needed; timing and sequencing of actions developed; customer engagement and consideration of the individual renovation context; attractiveness and motivation; and automation. This will help other countries as they explore the options for such a passport. Having the details of three case studies is vitally important. This is a relatively new concept and it is encouraging that there are organisations experimenting with this passport concept.
The full report is available here. It is definitely worth reading.
