Information for the project:

Renovation of a five-storey building, built in 1980, with a basement and a sloping roof with an intermediate uninhabited space above the last residential floor. The structure is frameless, prefabricated, panel, reinforced concrete (large-panel residential buildings).

During the construction process the following activities were performed:

  • Dismantling of the existing wooden and metal joinery and installation of new PVC joinery with double glazing;
  • Replacing the entrance door with new aluminium joinery;
  • Laying of façade thermal insulation – plates of polystyrene foam (EPS and XPS) and structural external plaster;
  • Making a sloping wooden structure covered with concrete riles;
  • Laying of PVC foil vapour insulation, thermal insulation of stone wool and waterproofing membrane;
  • Making a sheet metal plating with polyester coating on boards, eave faces, dormer-windows and around chimneys, installation of drainpipes and gutters of sheet metal with polyester coating;
  • Painting of the walls and ceilings of the staircase with latex;
  • Installation of fire-resistant, self-closing doors;
  • Making of protective grounding.

In the course of construction, the design solutions were met, as well as the energy-saving measures planned for the building in the energy audit were implemented.

As a result of the implemented energy efficiency measures, the following was achieved:

  • higher level of energy efficiency of the multi-family residential building and lower energy costs;
  • improved performance to extend the lifecycle of the building;
  • providing conditions for a living environment in accordance with the criteria for sustainable development.
