The main problem identified in buildings is, above all, low energy efficiency, resulting in high operating costs and significant emissions of environmentally harmful substances. The main objective of the project is to increase energy efficiency through thermal modernisation of the buildings covered by the project.The project is implemented for the period from 01 January 2017 to 31 October 2018.
