The concept of the individual building renovation roadmap

An in-depth case study of four frontrunner projects

28 Feb 2018
Description

Roughly 97% of the European Union (EU)’s building stock, amounting to over 30 billion m2, is not considered energy efficient, and 75 to 85% of it will still be in use in 2050. Defining a pathway towards a ‘highly efficient and decarbonised building stock by 2050’ is a fundamental pillar of the revised Energy Performance of Buildings Directive (EPBD), requiring the transformation of the majority of buildings from highly inefficient to, at least, nearly zero-energy buildings.

This is an opportunity to significantly improve the quality of the building stock and the living conditions of all Europeans. However, to achieve this goal, the multiple barriers building owners face when planning a renovation must be overcome. One of the main barriers to renovation is the lack of knowledge about what measures to implement and in which order. Building renovation is often considered a burden that many associate with time-consuming planning, uncertainty about the value of the planned measures, dust and unreliable professionals.

The iBRoad EU-funded project works on eliminating these barriers by developing an Individual Building Renovation Roadmap for single-family houses by providing a customised renovation plan over a long-term period (10-20 years).

This report offers an overview of the process behind the creation of an Individual Building Renovation Roadmap and covers the key issues that need to be addressed to allow its development and implementation. Real-life examples based on four existing initiatives revolving around the concept of individual building roadmaps and passports are used in this report to demonstrate how the different elements can be designed and implemented: Denmark (BetterHome), Flanders (Woningpas and EPC+), France (Passeport Efficacité Énergétique) and Germany (Individueller Sanierungsfahrplan).

The overview of the processes behind the creation of an Individual Building Renovation Roadmap in the four real-life examples offers valuable lessons about the route that leads to a successful development and implementation. Regardless of the nature of the originator (private, public or a combination of both) or its geographical coverage (municipal, regional or national), creating the conditions for a successful implementation of a Building Renovation Passport requires careful planning. The process can be summarised in four main blocks: exploration, concept design, implementation and evaluation. The key success factors are summarised in Page 47 and 48.
