The subject of the project is a deep thermomodernisation of the public building, which is a fire station which also serves as a common room located in the Municipality of Ogrodzieniec. The building was erected in the 1960s and was built in traditional technology. At present, it requires thermomodernisation and replacement of the heat source. As part of the implementation of the project, the following works are foreseen, which will consequently lead to a decarbonisation of the building and primary energy savings consisting of: insulation of external walls, warming of the roof, replacement of window and door joinery, replacement of boiler, replacement of the c.c. installation together with radiators, preparation of as-built documentation.
