The OSR-Coop Project aims to gain a comprehensive understanding of the concept of One-Stop Shop (OSS) in the context of citizen-led renovations (CLR), which have been focal points of's (the European federation of citizen energy cooperatives) endeavors for quite some time.

The CLR concept, viewed through the lens of energy cooperatives and energy communities, has evolved from the diligent efforts of's citizen-led renovation working group and other related projects. Therefore, the OSR-Coop project not only benefits from the valuable insights of partner cooperatives, which form an integral part of the project, but also draws upon the extensive groundwork and foundations that were laid even before its inception.

The concept

Citizen-led renovation can encompass different renovation and energy efficiency activities, ranging from performing energy audits and providing information to taking care of the complete renovation process from planning and financing to delivery (a 'one-stop shop' service). Although the offered services differ between cooperatives, they all share a few common traits:

  • Citizens are involved in the renovation process and governance of the initiative;
  • Cooperatives act as a trusted partner;
  • The development of local businesses and the skills of the people involved is supported;
  • Solutions are adapted to local conditions.

In doing so, local networks and partnerships are created, bringing together both government and relevant actors – from contractors to community groups – driving the development of a sustainable renovation strategy for the community.
