Situation before the contract and client requirements

The public tender for the energy retrofit of the City of Ljubljana included 49 buildings, among which were elementary schools, kindergartens, libraries, cultural institutions, healthcare centers, sports centers and administrative buildings.

The aim of the city was to improve the energy efficiency of the buildings with minimal investment, in accordance with the environmental policies of Ljubljana and the city’s reputation of European Green Capital. In order to successfully carry out the implementation of such an ambitious project, Resalta and Petrol signed a partnership contract.
