Sosnowiec, Poland Construction and Development, Environment and Resource efficiency
EU funded project



The Investment Programme will be carried out in the Municipality of Sosnowiec, located in the Silesian Voivodeship, as well as in the whole area of the Silesian Voivodeship and in the neighbouring Voivodeships in Poland (Opole voivodeship, Lower Silesian Voivodeship and Lesser Poland Voivodeship).

The investments will address the renovations of the existing multi-apartment residential building.

More than 150 buildings (representing around 5 000 apartments) will be renovated (equivalent to around 255 000 m²).

The total estimated contributions are:
• Energy Efficiency – Annual total energy saved 25.54 GWh representing a reduction of 45% compared to the baseline.
• Renewable Energy – Annual total 0.75 GWh RE electricity generation.
• CO2 reductions – Annual total reductions of 9 141 CO2eq t representing a reduction of 47% compared to the baseline.

Why it works

The project is developed with the help of the ELENA programme which is providing 90 % grant assistance.

ELENA provide an OSS implementation support to around 150 multi-apartment residential building owners located in the Silesian Voivodeship with possible extension to the: Opole Voivodeship, the Lower Silesian Voivodeship, and the Lesser Poland Voivodeship.

MZBM-TBS Sosnowiec creates the Project Implementation Unit (PIU) that consist of MZBM-TBS Sosnowiec existing internal staff (Project Coordinator and seven other staff members, experts working part-time for the ELENA project).

The PIU will be supported by external technical consultants, contributing to achieving the ambitious objective of renovating more than 150 multi-apartment residential buildings, targeting a reduction of the final energy consumption of around 45% and achieving annual CO2 emissions reduction of about 9 141 tons.
