This report is the summary of the Policy meeting held on the 5th of November in Barcelona (Spain), with the support of the Diputació de Barcelona. Spanish and French policymakers of their respective governments had the opportunity to contrast their initiatives, together with experts of the academia and the third sector.

The report offers theoretical and practical guidance to existing or future one-stop shops (OSS) related communities. These OSS communities are to be understood in a broad sense and thus include either candidate organisations or already established one-stop shop. It offers advice on how to build a sustainable business model through a use case approach and which tooling could support these ‘candidate OSS’

The paper offers an ex-ante (pre-implementation) and ex-post (post-implementation) evaluation of 37 OSS business models currently operating in the EU renovation market. The evaluation was performed using eight indicators that evaluate key factors in a business model. The study also provides suggestions for future OSS development, which include comprehensive competitor analysis, enhanced communication strategies, and strategic partnerships to ensure long-term sustainability and success.

The second edition of the EU Peers summit gathered more than 100 participants, including many one-stop shop (OSS) practitioners from across the EU, for two days of peer learning, practical exchanges and strategic reflections on the future of OSS. Read more about it in the report.

The Guideline for OSS Service Providers developed within the RenoWave project is a practical and comprehensive resource for organisations that already operate, plan to establish, or support an Energy One-Stop-Shop (OSS) for home-owned multi-apartment buildings (HOMABs). The guide explains why energy efficiency is essential for the Baltic Sea Region, outlines the policy framework shaped by the revised Energy Performance of Buildings Directive (EPBD), and describes the diverse renovation challenges across different ownership models. At its core, the document presents a step-by-step approach for building an effective OSS: analysing market gaps, choosing the appropriate organisational model, defining target groups, designing a viable business model, and launching services in cooperation with local stakeholders. It details the key pillars of a successful OSS—overview and detection of building stock, marketing and communication, training, collaboration forums, and technical assistance—providing actionable recommendations for each. The guide emphasises the value of OSSs as neutral, trusted facilitators that simplify renovation journeys for homeowners by offering a single access point for information, financial guidance, supplier coordination, and technical expertise. Through best practice examples from across the Baltic Sea Region, it showcases how data-driven tools, targeted communication, and collaborative networks can accelerate energy-efficient renovations and strengthen local market capacity.
