The proposed project will renovate the leading school of the ‘Ivan Gundulic’ primary school which will move from the current energy class C to energy class B. In the realisation of the project, it will replace and isolate the ongoing roof of the building, the external walls, under the ground floor, ceiling towards the unheated space, will replace the external joinery and install new LED lights, and new performing radiators will be installed. In addition to the energy renovation measures, an promotion of the proposed project will be carried out and will have a wider impact, as Ivan Gundulića is one of the largest schools in Dubrovnik.
