The aim of the project is to increase energy efficiency in the public sector by modernising two buildings belonging to the Municipality Office in Wisła- City Hall and the Voluntary Fire Service. Material scope of the project for the UM building: thermomodernisation by replacement of window and door joinery, warming, insulation of the roof, replacement of junctions and replacement of central heating installations, installation of a heat pump. In the TSO Jawornik:termomodernizacja through replacement of joinery and warming, replacement of central heating installations, installation of a heat pump. The implementation of the project will contribute to improving air quality, reducing emissions of pollutants into the air by replacing old heating systems with low energy efficiency. A lower demand for heat will be achieved, resulting in a reduction in the amount of gases from the combustion process into the atmosphere.
