Evaluating the development of Integrated Home Renovation Services for condominiums

This report evaluates the development needs of IHRS tailored for condominiums in Flanders and the Netherlands. It focuses on two complementary models: a public-led approach piloted in Flanders through the Flemish Climate and Energy Agency (VEKA) and local Energy Houses, and a private-led approach represented by the Dutch service provider WNR. 

To support this evaluation, we developed a conceptual framework based on tailored evaluation criteria designed to assess the viability of the business models. These criteria were informed by a review of relevant literature, project deliverables, and practical observations, and are used to assess key aspects such as financial stability, adaptability, customer focus, and operational efficiency. It examines the viability of the tested business models, the effectiveness of stakeholder engagement activities, and the conditions required for the long-term operation and replication of IHRS for condominium renovations.  

The findings show that the main barriers to renovation are not technical but organisational, financial, and social. CAs often struggle with fragmented ownership structures, lengthy collective decision-making processes, limited technical knowledge, uncertainty about costs and benefits, and difficulties in coordinating multiple stakeholders. These challenges frequently delay renovation projects even when technical solutions and financial support mechanisms are available. 

Across the Belgian and Dutch pilot experiences, the evaluation demonstrates that IHRS can significantly improve renovation readiness by providing a structured process, independent advice, technical assessments, financial guidance, and continuous support throughout the renovation journey. In particular, the role of process coaching and stakeholder facilitation proved essential in helping co-owners understand renovation options, build consensus, and move from initial awareness towards concrete investment decisions. 

The evaluation also assessed the broader ecosystem required to support condominium renovations. The results highlight the importance of collaboration between municipalities, Energy Houses, contractors, financial institutions, condominium managers, homeowner organisations, and public authorities. National Advisory Boards and international workshops contributed to validating project results, identifying barriers and opportunities, and facilitating the transfer of knowledge to stakeholders across Europe. 

The analysis of the different IHRS models shows that both public-led and market-driven approaches can support condominium renovation, provided that they are embedded within a supportive ecosystem and have access to sustainable funding and business models. However, challenges remain regarding long-term financing, affordability for homeowners, legal and governance barriers, and the capacity required to provide intensive process support. 

Overall, the evaluation concludes that IHRS provide an effective framework for addressing the specific challenges of condominium renovation. By combining technical expertise, financial guidance, stakeholder coordination, and process facilitation, IHRS can accelerate renovation decision-making and improve project readiness, while creating the conditions for broader market uptake and replication across Europe.
