The aim of the project is to improve energy efficiency in 14 multi-family residential buildings owned by the City of Siemianowice Śląskie, located at ul. Deji, Żwirki and Wigura, Michałkowicka, Wiejska and Wróblewski. The existing partitions of buildings do not meet the current requirements for thermal insulation of partitions, so that the facade warming (to the depth of the foundations, min. 1 m below the ground level), the roof of buildings, and additionally warming of the ceiling between the attic and residential premises are foreseen. In addition, the replacement of used wooden carpentry in the attic and cellars, entrance doors to buildings, new roof coverings from heat-heated papa, replacement of lighting for energy-saving and vertical insulation of the foundation walls to the height of the plinth are planned. The project results from the Local Regeneration Programme for the City of Siemianowice Śląskie for the years 2016-2022.
