Thermomodernization of multi-family residential buildings located in Przemyśl at ul. Lelewela 8 and 10
The aim of the project was to perform a deep, comprehensive thermal modernization of the buildings of the Housing Community “Lelewela 8 and 10” in Przemyśl, increasing their energy efficiency and reducing the costs of heat energy consumed by them.
The project covered:
- Multi-family building at ul. Lelewela 8 in Przemyśl, 37-700 Przemyśl (Przemyśl city commune, Przemyśl poviat, Podkarpackie voivodship) – located on the plot, possibly 1056 (plot ID: 186201_1.0205.1056), registration unit: 186201_1 M.PRZEMYŚL, precinct 205, plot area: 0.5515 ha, land and mortgage register number: PR1P / 00054797/6
- Multi-family building at ul. Lelewela 10 in Przemyśl, 37-700 Przemyśl (Przemyśl city commune, Przemyśl poviat, Podkarpackie voivodship) – located on the plot, possibly 1056 (plot ID: 186201_1.0205.1056), registration unit: 186201_1 M.PRZEMYŚL, precinct 205, plot area: 0.5515 ha, land and mortgage register number: PR1P / 00054797/6
The condition of the building’s structural elements, both in the building at ul. Lelewela 8 and at ul. Lelewel 10 was satisfactory, however, the external partitions (walls, flat roof) and the basement ceiling were characterized by low thermal insulation, i.e. low thermal resistance values, which contributed to excessive heat losses.
The scope of works performed in each of the buildings was consistent with the optimal variant of the developed energy audits and included:
- The building at ul. Lelewela 8:
- insulation of all non-insulated walls of the building with the use of 15 cm thick foamed polystyrene and mineral wool boards, execution of the building’s flashings and insulation of the plinth with 10 cm thick polystyrene boards.
- insulation of the flat roof by blowing in granules made of mineral wool with a thickness of 22 cm
- insulation of the basement ceiling by spraying thermal insulation with a thickness of 8 cm
- The building at ul. Lelewela 10:
- insulation of all non-insulated walls of the building with the use of 15 cm thick foamed polystyrene and mineral wool boards, execution of the building’s flashings and insulation of the plinth with 10 cm thick polystyrene boards.
- insulation of the flat roof with the method of blowing in granulated mineral wool with a thickness of 22 cm
- insulation of the basement ceiling by spraying thermal insulation with a thickness of 8 cm
The project is managed by the Housing Community “Lelewela 8 i 10” in Przemyśl.
