This report presents a roadmap for decarbonising public buildings on the island of Korčula, Croatia. Based on energy certificates and audits, energy consumption data was analysed for 15 buildings. The findings indicate that heating energy consumption varies between 55.97 and 253.5 kWh/m² per year, with an average of approximately 116.6 kWh/m² per year.
Two buildings, Gradska Uprava Grad and Djećji vrtić Korčula, underwent a comprehensive analysis to identify opportunities for improvement and enhance their operational efficiency and sustainability. Proposed measures include the installation of energy-efficient lighting, upgrades to the heating system and improvements in thermal insulation to reduce electricity consumption. These interventions are expected to generate total energy savings of 242,313 kWh, representing a reduction of over 75.2% in energy consumption, with estimated financial savings of 37,732 Euros per year. Implementing these measures would require an initial investment of approximately 554,006 Euros.
The report also outlines a detailed roadmap to enhance energy efficiency and integrate renewable energy solutions in public buildings.
Finally, the successful implementation of these initiatives relies on a strong regulatory framework and adequate financial support, both of which are addressed in the report.
