This report evaluates the performance and development needs of Integrated Home Renovation Services (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.
The analysis combines multiple data sources, including document reviews, observations, co-creation workshops, and in-depth interviews with co-owners, board members, IHRS actors, and public stakeholders involved in energy renovations across eight condominium associations (CAs) in both Flanders and the Netherlands. This qualitative research was further complemented by two questionnaire surveys, one targeted at CA co-owners in Flanders and the Netherlands, and another at a broader group of property owners across the EU. The EU-wide survey revealed consistent patterns in motivations, barriers, and support needs, highlighting the relevance of the findings beyond the immediate case studies.
Both IHRS models aim to simplify the complex renovation journey for CAs by offering advisory, coordination, and technical support. However, each model faces specific challenges: The public-led model benefits from neutrality and policy alignment, but often lacks long-term engagement beyond the masterplan phase and struggles with resource intensity. The private-led model shows strengths in flexibility, phased planning, and client-centric service, but must overcome barriers related to trust, financing accessibility, and coordination with public actors such as municipalities and housing corporations.
The report provides detailed business model recommendations for improving service delivery across nine Business Model Canvas components. These are supported by policy recommendations targeting national and local governments.
Limitations of the Study: While this report offers rich insights, it is based on a limited number of in-depth IHRS providers, three in Flanders and one in the Netherlands. The findings are therefore not statistically generalizable but reflect qualitative depth. The co-owner interviews may also reflect the views of more engaged or vocal residents, potentially underrepresenting passive or non-participating co-owners. Finally, the long-term outcomes of renovation processes were not yet fully observable at the time of this analysis. Despite these limitations, the study provides robust evidence for informing business model optimization and targeted policy support for IHRS models across varying governance contexts. The developed evaluation framework also offers a transferable tool for assessing similar renovation service models in other European contexts.

The primary objective of the CondoReno project is to create and replicate Integrated Home Renovation Services (IHRS) in Flanders and the Netherlands to achieve label A condominium renovations with condominium associations. The project addresses the challenge of coordinating multiple stakeholders involved in the renovation of co-owned condominiums, including co-owners, condominium associations (CAs), condominium managers, contractors, financial institutions, and government bodies. The report outlines the steps taken to build and multiply IHRS, focusing on stakeholder mapping, co-creation with internal and external stakeholders, digital support, and quality assurance. Subsequently, we describe the initiatives that WNR and the energy houses of Antwerp, Ostend and Mechelen took to develop an IHRS through co-creation processes with local stakeholders from the demand and the supply side. These initiatives concern local stakeholder groups in The Netherlands and Flanders, various training and knowledge exchange initiatives, a digital resource center, the creation of two IHRS originating from the supply side. The report demonstrates that co-creation processes can significantly enhance the demand and supply of IHRS for condominiums. Key recommendations include strengthening collaboration between authorities, aligning renovation incentives with CA needs, and exploring long term and innovative financing models. The development of a standardized IHRS model and stronger public-private partnerships are also emphasized. The CondoReno partners will focus on further refining their IHRS models, implementing and disseminating the CRM system, expanding training programs, and exploring new financing options.

This CondoReno Deliverable is a comprehensive document designed to aid Condominium Associations (CAs) in the Netherlands and Flanders with energy renovations. Spearheaded by WNR with collaboration from experts at TU Delft and other institutions, the deliverable introduces a Renovation Roadmap and a Financial Calculation Tool. These are intended to streamline the renovation process by providing a structured approach and simplifying financial decisions for CAs. The Renovation Roadmap serves as a strategic guide, helping CAs understand the entire renovation journey, including the necessary decisions and the roles of different stakeholders. This step-by-step plan (investment proposal method) provides guidance on when which decisions should be made, linked to a decision by the GM. In addition to the widely supported start of a renovation process, the most important decisions are the decision to invest and the final assignment to renovate. Alongside this, the Financial Calculation Tool offers a preliminary financial overview, enabling CAs to assess the economic feasibility of renovations before committing. This tool is particularly designed to present a simplified comparison of costs before and after renovations, incorporating variables like potential subsidies and energy savings, though it does not account for inflation to maintain a consistent comparison basis. The investments and energy savings come from the advisory reports or master plan studies of various types of consultants, such as architects or engineering firms. The primary aim of this deliverable is to facilitate the decision-making process for CAs, reducing barriers to undertaking deep renovations. By providing a clear financial picture and potentially demonstrating cost savings and benefits over time, the tool encourages more CAs to commit to substantial energy efficiency improvements. Future plans for the deliverable include a series of reviews and updates to refine the tool, with considerations for developing it into an app or interactive web tool based on the outcomes of these reviews and available budget. This progression is aimed at enhancing accessibility and user interaction, further supporting CAs in their renovation endeavours. The ultimate goal is to accelerate energy renovations across condominiums by equipping CAs with necessary insights and tools for informed decision-making.
