In the Belgian capital, the EU Peers Summit 2025 (October 14–15, 2025) took place — a central gathering of experts, organizations, and public institutions working on the development and implementation of One-Stop-Shop (OSS) models that support building energy renovations across the European Union. The event brought together representatives from numerous European countries, including DOOR – Society for Sustainable Development Design (Anamari Majdandžić) and KLIK – Križevci Climate Innovation Laboratory (Martina Nemčić and Hrvoje Seleš).
The two-day, three-part event was organized by the European Climate, Infrastructure and Environment Executive Agency (CINEA) with support from the EU PEERS network. Its goal was to foster the exchange of experiences and best practices among organizations developing and implementing models to assist citizens in energy renovation and the transition to sustainable energy.
The program began on Tuesday, October 14, with the Practitioners’ Workshop. After a welcome and opening remarks by CINEA representatives, participants took part in an interactive activity titled “OSS Bingo: Find someone who…”, designed as a dynamic way for organizations to get to know each other and share experiences. In the afternoon, a workshop titled “The devil lies in the details” focused on specific challenges in implementing the One-Stop-Shop model across different EU countries. The day concluded with a cocktail networking event, encouraging further idea exchange and partnership building.
On Wednesday, October 15, KLIK and DOOR representatives participated in the session “Deep dive into Belgian One-Stop Shops.” Belgian hosts — SP Wallonia, Homegrade (Brussels), and VEKA (Flanders) — presented their OSS models and current challenges they face.
During the “World Café” session, participants rotated between three thematic tables, each led by one of the Belgian organizations. The discussions addressed several key issues: the potential introduction of paid OSS services, how regional authorities can collaborate with the private sector in developing the energy renovation market, and how to maintain OSS independence when partially financed by private sources. Participants shared examples from their own countries, compared approaches, and offered ideas for more sustainable funding and more effective outreach to end users.
The summit concluded with a public final event titled “How cities and regions are benefitting from One-Stop Shops.” Through closing presentations and networking, participants agreed that the OSS model is crucial for accelerating the energy transition — particularly at the local level, where citizens need direct support and clear information.
Croatian experience in the European context – LIFE crOss renoHome project
The participation of DOOR and KLIK at the EU Peers Summit once again confirmed the active role of Croatian stakeholders in the European network promoting a fair, inclusive, and efficient energy transition.The crOss renoHome – Croatian One Stop Shop for Integrated Home Renovation project focuses on developing and implementing an integrated model for the renovation of single-family and multi-apartment buildings through the One-Stop-Shop (OSS) system — with DOOR managing the OSS in Zagreb and KLIK in Križevci.
In collaboration with the Croatian Green Building Council, a digital tool is also being developed to connect contractors and financial mechanisms in one place for citizens. The project’s main goal is to provide a comprehensive, all-in-one energy renovation solution — from technical consulting and financial planning to implementing concrete energy efficiency measures.
This approach simplifies and integrates the renovation process, encouraging more citizens to invest in improving their homes’ energy performance. Participation in the two-day Brussels event enabled DOOR and KLIK to exchange experiences with EU partners, learn from good practices, and contribute to the further development and adaptation of the OSS model to the Croatian context — thereby strengthening Croatia’s role in the European energy transition.
