Achieving cost-effective deep renovation: Key considerations for local and regional authorities

Local and regional authorities are crucial in ensuring deep renovation aligns with economic and environmental goals. Beyond reducing energy consumption, it enhances resilience, optimises investment, and supports long-term sustainability.

In this report produced by the CROSS project, you will find:

🔹 A holistic approach – At least 75% of a building’s energy should come from renewables, integrating solar panels, district heating, and smart monitoring.
🔹 Long-term financial planning – A 20-year assessment helps account for operational costs, ensuring the best return on investment.
🔹 Sustainable materials – Prioritising reusable, non-toxic materials supports a circular economy and healthy indoor environments.
🔹 Structural resilience – In seismic areas, reinforcement techniques ensure energy renovation enhances building stability.
🔹 Smart digitalisation – Tools like BIM improve planning, integration of efficiency measures, and post-renovation performance tracking.
🔹 Funding opportunities – EU schemes such as InvestEU, ERDF, and RRF support large-scale renovation, requiring alignment with sustainability criteria.

About CROSSS

The CROSS project, coordinated by REGEA, establishes and operates a regional one stop-shop (OSS) in order to accelerate the renovation wave in the public sector covering a territory of four regional and 88 local authorities in Croatia and offering a comprehensive, all inclusive service from technical, financial to legal advice, procurement and quality assurance of works. The long-term objective is to replicate this concept to a wider area covering Croatia and beyond as well as to ensure the long term sustainability of the OSS.
