According to the European Climate Neutrality Observatory, “progress on buildings has been far too slow” and achieving the zero-emission building stock by 2050 target means Member States have no time to lose. The recent adoption of two major directives for the European Green Deal (the Energy Efficiency Directive and the Energy Performance of Buildings Directive) has given Member States a framework for reducing emissions and energy use in buildings across the EU, together with new targets, policies and tools. Among other things, both Directives recognise one-stop shops (OSS) as a major tool for boosting home energy renovation. OSS offer an integrated service package that makes the complex renovation process more attractive, simpler and accessible to all homeowners. They all pursue a common objective: boost home energy renovation by supporting homeowners in their renovation journey. Building on the experience and lessons learned ‘in the field’ by the five French Third-Party Financing companies (a specific local OSS model), SERAFIN association drafted key recommendations for Member States wishing to create a dream country for OSS. Here is what Member States should do!
