The subject of the project is the implementation of a low-carbon project consisting of the exchange of traditional sources of thermal energy (mainly coal furnaces) with modern, ecological heat sources in 70 single-family residential buildings in Dąbrowa Górnicza, characterised by a minimum standard of energy efficiency. As part of the exchange of heat sources for residents, 70 air-water heat pumps are planned for the needs of central heating and domestic hot water. The project aims to improve air quality, promote energy from renewable sources and improve energy security.
