The project focuses on the energy renovation of the Slavonski Brod Municipal Court building to achieve a saving of 79.95 % in the budget for heating, in primary energy 89.27 %, modernising the building’s design and improving the quality of life and working in the building with a positive impact on the environment. A renovated municipal court building in Slavonski Brod will become a paradigmatic example of the successful practices that will subsequently apply to the energy renovation of other buildings in the judiciary and the prison system characterised by high energy consumption. The target group of this project is composed of judges, prosecutors and deputy prosecutors, officials and employees within the judicial authorities of the Ministry of Justice and citizens.
