Expert consultation in Kranj: How can the One-Stop-Shop (OSS) model facilitate the renovation of multi-apartment buildings?
On 22 January 2025, City of Kranj hosted the expert roundtable One-Stop Shop (OSS): the state of play and support for residential renovations in Kranj, bringing together building managers active in the Gorenjska region. The aim of the event was to jointly identify concrete solutions for faster, higher-quality and better-coordinated energy renovations, and to co-create a local OSS model within the framework of the LIFE Renov-AID project.
Renovation as a necessity, not a choice
In the opening session, Jure Vetršek (IRI UL) emphasised that over the next 20–30 years, virtually the entire existing building stock will need to be renovated. Multi-apartment buildings pose a particular challenge due to decision-making procedures, financing constraints and complex administrative processes. The interactive introduction clearly highlighted the gap between awareness of the urgency of renovation and homeowners’ willingness to take action, especially in times of high energy prices, when consumption is lower but bills often remain high. Eva Romih (City of Kranj) underscored that the municipality acts as a facilitator rather than an implementer of renovations, and that through the development of the OSS, Kranj aims to provide homeowners and building managers with a clear “renovation roadmap” and better integration of existing support mechanisms.
Renovation landscape in Kranj and the role of building managers
Primož Gutman (ZRMK) presented an overview of the renovation status in Kranj: most multi-apartment buildings were constructed between 1960 and 1980; façade and roof insulation are the most common measures, while technical systems and structural safety are often overlooked. Positive examples come from the Planina district, where more than half of the apartment blocks have already undergone at least partial energy renovation. Jože Dolenc (Domplan) stressed the crucial role of building managers as proactive intermediaries between homeowners: regular communication, five-year maintenance plans, high-quality detailed design documentation (PZI), and independent site supervision are prerequisites for successful renovations. He also highlighted systemic barriers, such as the requirement for 100% homeowner consent for loans linked to the reserve fund, which is in practice almost impossible to achieve in larger buildings.
Financing and trust
Luka Petkovšek (Eko sklad) presented current and upcoming financial incentives, including higher subsidies in 2025, covering 30–50% of eligible costs for multiple measures, and new loan options via the reserve fund. The discussion showed that beyond the level of financial support, homeowner trust remains a key challenge, particularly among energy-vulnerable households, where interest often remains low despite 100% subsidy rates.
Interactive workshop: building typologies from Kranj
In the core part of the event, participants worked in groups on five typical building cases—from protected heritage buildings in the historic city centre to large multi-entrance blocks with more than 200 apartments. The joint conclusions were clear:
- Renovation is not only a technical challenge, but above all an organisational and communication one.
- “Local heroes” within buildings play a decisive role and need professional support.
- The OSS can significantly contribute through independent advice, support with decision-making and consents, clarification of financing options, and coordination of experts.
- There is a growing need for group renovations of multiple buildings or entire streets, which can reduce the costs by 20–30%.
OSS for Kranj – the next steps
The event confirmed strong local support for the development of a Kranj-specific OSS model, providing homeowners with independent, transparent and trustworthy support, while enabling building managers to more effectively lead complex renovation projects.
City of Kranj and Renov-AID project team will use the outcomes of the roundtable in further development of the OSS. Participants will receive presentation materials and a structured renovation pathway that can be directly applied in their professional practice.
