Building:
Kista Science Tower, Kista (Stockholm)
Year of construction:
Size:
32 storeys, m2 double skin façade, floor area 700 m2/storey i.e. appr m2
Use:
Office non-public, cell-type or open-plan office
Architect:
White arkitekter (participated during the entire building process)
Contractor:
NCC
Facade contractor
FFT – Feldhaus, Flexfasader, Trosa Glas
Motive:
Image, commercial property development project, fully glazed façade to give a feeling of volume
Principle of façade construction:
Two of the three facades are double skin facades, the third (to the north) is a single skin facade. The double skin facades are of the type corridor façade with diagonal ventilation. In the cavity there are gangways on each floor and automatically controlled (2.7 m sections) perforated Venetian blind. Internal Venetian blinds will be installed on the north facade. The windows are non-openable.
Façade construction, material:
Prefabricate one-storey high aluminium construction
Outer skin: 8/10 mm H, non-coloured
Inner skin: double-pane sealed glazing units with LE glass, non-coloured, 1.35 m on centre
HVAC:
Balanced ventilation with heat recovery, indoor design temperature in winter 22 ± 1,5 ºC, in summer 24 ºC at design outdoor temperature + 26 ºC. Cooling from active cooling beams 2.7 m on centre. Cooling energy source is district cooling. Heating provided by radiators. Heating energy source is district heating.
Light:
No daylight control system, HF fluorescent lighting
Fire:
Every fourth storey is fire sectioned. The office areas are equipped with a sprinkler system.
Energy use: 2004
Electricity 93 kWh/m²year, heating 111 kWh/m²year, cooling 42 kWh/m²year i.e. total energy use 246 kWh/m²year
