The ProRetro project
In contrast to Germany, One-Stop-Shops are already operating successfully in the building renovation market in other European countries such as France, the Netherlands and Sweden. The ProRetro project, funded by the European Commission, is therefore developing and testing comparable services in five German cities and regions. The project aims to overcome barriers to residential energy efficiency renovations with One-Stop-Shops designed to meet the needs of German customers. ProRetro supports both owners of residential buildings and condominium owners’ associations who want to renovate their house. The German project partners are regional energy agencies and small and medium enterprises located in different regions of Germany. Moreover, five peer partners from other European countries that have experimented with and implemented successful One-Stop-Shop business models support the German project partners. The structure of the ProRetro project is illustrated in the figure in the below paragraph.
French-German cooperation within I-Heros and ProRetro
The German partner in the I-Heros project, ZEBAU GmbH from Hamburg, is working closely with the partners from ProRetro to determine the transfer potential of the solutions developed in the One-Stop-Shop in Toulouse to Germany. The knowledge from ProRetro on German One-Stop-Shops and specific challenges of the German market are included in the replication analysis. A joint workshop has already been held in June 2022 with the German climate protection and energy agencies to present the concept of One-Stop-Shops with reference to the Toulouse model within I-Heros and the model from Hanover within ProRetro (Read more about the workshop here). In the final phase of the two projects, the Wuppertal Institute and ZEBAU will exchange recommendations for the establishment and further development of One-Stop-Shops.
