Promoting building retrofits in the private residential sector through One-Stop-Shops in Germany

Periodic Reporting for period 1 - ProRetro (Promoting building retrofits in the private residential sector through One-Stop-Shops in Germany)

Reporting period: 2020-06-01 to 2021-11-30

The EU-funded ProRetro project will offer new One-Stop-Shop services in five German cities or regions, where homeowners show a reluctance to retrofit. The project aims to overcome barriers to residential energy efficiency renovations with One-Stop-Shops designed to meet the needs of German customers. One-Stop-Shops facilitate (energy efficiency) renovations by being a single point of contact. ProRetro will draw from best practice examples in other EU Member States and tailor these to fit the German reality. These new One-Stop-Shops will cover the customer’s entire journey of a building renovation, starting from the initial energy audit and planning to the contracting of construction work, implementation, monitoring, quality control and approval. ProRetro supports owners of residential buildings and condominium owners' associations who want to renovate their house. The One-Stop-Shops developed in the project will be put to test in five German cities and regions. One-Stop-Shops shall reduce non-financial cost (information and search costs, administrative costs) incurred by building owners and increase the quality of energy efficiency renovations. This will be due to the experience and knowledge the One-Stop-Shop has gained from organising a large number of renovations.

The German project partners are regional energy agencies and small and medium enterprises. Organisations from other European countries that have experimented with and implemented successful One-Stop-Shop business models already will support the German project partners. Peer-to-peer learning will make the project's success more probable.

Thereby the ProRetro project aims to
- Overcome barriers to residential building refurbishment by offering new One-Stop-Shop services to customers in five German cities/regions
- base the One-Stop-Shop design on the needs of customers so that they are attractive to customers,
- conceptualise, plan, implement and monitor and evaluate the new One-Stop-Shops,
- prepare their continuation beyond the project lifetime,
- cover the whole customer journey of a building renovation from audit/advice, planning, contracting, implementation and monitoring, quality control and approval – and involve respective stakeholders/experts in the service offer,
- build on information and experiences in designing and implementing One-Stop-Shops from best practice examples in other European countries and establish peer-learning structures with those organisations.
Work peformed in reporting period 1 encompassed research on existing experience with One-Stop-Shops in Europe (literature review) and generating new data by surveying potential customers on their thoughts on the idea of a One-Stop-Shop and wishes for such a service. Research activities also included compiling a list of different strategies to activate and motivate homeowners. A large share of work in this reporting period was dedicated to developing five business models for One-Stop-Shops for five German cities/regions and different target groups (homeowner associations and owners of single- and two-family homes). These business models were evaluated during individual focus group discussions. Focus group discussion participants gave feedback on the business models developed by the implementing partners. Another task was to learn about other One-Stop-Shops in Europe and get feedback on German business models from functioning One-Stop-Shops in Europe during two peer workshops. Work was also performed to set up a monitoring system for the impact's of the German One-Stop-Shops. Other foci were devising and implementing communication activities to make the project and approach well-known (e.g. website, blog, newsletter) and networking with other projects with similar goals (both Horizon 2020 and national projects).
During reporting period 1 progress was made towards services that cover the complete customer journey of an energy renovation and, consequently, fulfill the criteria of a One-Stop-Shop for five German cities and region. These One-Stop-Shops are supposed to ease energy renovations for homeowners by reducing many barriers (e.g. information and search costs, time needed) of an energy renovation. Thereby, they should facilitate an increase of renvovation rates and, consequently, lead to higher energy savings, less GHG emission, less air pollutant emissions, additional investments into the building stock and generate demand the local economy profits from.
