Swedbank AB, Stockholm

Openness and transparency for the new headquarters

Building owner: Swedbank AB

Town/City: Stockholm 172 68

With some 750 branches in Sweden and 250 branches in the Baltic States, Swedbank is one of Northern Europe's largest banks. Its new headquarters opened in Sundbyberg in the spring of 2014. The town lies in the immediate proximity of Stockholm and is a district of the Swedish capital. A perfect location for a prestigious head office. The global Danish architects' firm 3XN designed a building that has a triple V-structure. This ingenious trick means that the building looks more like a building complex and not a large monolith, as suggested by the 45,000 m² gross floor area. "Openness and simplicity" is the architect's mantra for the Swedbank head office. Kampmann trench heating is part of the overall solution.

Openness: The long, high glass façade overlooking the street is the most obvious feature of transparency. The view from outside looking inside (and vice versa) remains undisturbed thanks to the Katherm NK trench heating under the floor-height windows. The natural convection trench heating effectively screens cold air. The market-leading technology with a high-output PowerKon works efficiently and virtually invisibly beneath a stylish, understated Optiline roll-up grille.

Simplicity: 731 Katherm NK were installed as a continuous run within the Swedbank head office. The trench heaters stand out on account of their low thermal mass and are therefore easy to control. Quick delivery and fast installation with Eurokonus valve connections ensured a seamless and fast installation process in Sundbyberg.
