The object of the planned project is the modernisation of the building in Żmigród, according to the developed energy audit. The main objective of the project is to increase the energy efficiency of the building at ul. Poznańska 8 in Żmigród. The building being the subject of the project consists of a complex of 3 segments with mixed functions. In part A there is a multi-family residential area and it is a communal apartment, while part of the ground floor there are office spaces and two private flats with separate entrances.Segments B and C are non-usable rooms that used to serve as a dining room and common room for the Workers’ Hotel. Within the framework of the project, the applicant plans to carry out such tasks: 1.Development of project documentation with energy audit. 2.Works related to thermal modernisation of the building. They concern, among others, warming of the building, modernisation of hot water installations and heating installations. 3.Building works related to the reconstruction of the building. As part of this task, apartments in the building will be adapted to the needs of people with disabilities. 4.Investment supervision. 5.Project management. 6.Promotion measures. The project will improve air quality by reducing CO2 emissions through thermal modernisation of the facility and will increase energy savings. These goals will be achieved, among others, by warming the ceiling of buildings, replacing leaky windows and doors, modernising the hot water system or modernising the heating system. The implementation of planned renovation works is necessary in the framework of the project, as it would be useless and financially unprofitable to carry them out after the thermo-modernisation. The project will reduce the annual energy demand for heating and water heating by 72.81 %, while the annual energy cost savings are estimated at 52.21 %. In addition, the implementation of the project lawsuits
