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

The CROSS project presents comprehensive guidelines for cost-effective renovation.

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.
