It has 2 similar wings, 2 staircases, with similarly designed flats. The net area of the building is 3824 m2.
Unsatisfied overall present energy performance: Uwall = 1.0 W/(m2K), Uroof= 1.1 W/(m2K), Ufloor = 0.6 W/(m2K)), thermal bridges, lack or insufficient ventilation, water-proofing failures on balconies and on window drip molds. Windows with plastic frames have high thermal transmittance (Uwindow = 1.8 W/(m2K)) and broken closing mechanisms and fixings. Failures and water leakages in the area of chimney-roof. Possible overheating during winter season, insufficient thermal comfort at southern part of living spaces on summer period.
