Digital one‑stop‑shops, such as HORIS, reduce barriers to renovation by providing clear information, regulatory guidance and access to verified professionals. User‑centred design and hybrid support models are identified as key elements for effective scaling.
One‑stop‑shops for home renovation, recognised in the Energy Performance of Buildings Directive, consolidate technical guidance, financial information and regulatory support in a single access point. This model enables citizen‑led renovation and combines digital tools with in‑person assistance to ensure accessibility and trust.
The HORIS project demonstrates how a digital platform can simplify renovation choices through a structured repository of energy‑efficiency measures, regulatory guidance and interactive tools that estimate savings and investment needs. Its adaptation to Portugal, Italy and Spain confirms the transferability of this approach across different national and local contexts.
Operational experience highlights the importance of regulatory alignment, professional verification and targeted training. HORIS also shows the role of consumer organisations as trusted intermediaries and the need for sustainable funding models to scale these solutions.
