A NINETEENTH-CENTURY banking hall in Austria has become one of the first heritage buildings in Europe to feature circadian lighting with variable colour temperatures.
The head office building of the General Savings Bank Upper Austria in Linz – which was completed in 1892 – now features a simulated daylight cycle in 10 large pendant luminaires in the executive foyer.
The architects’ idea was that the pendant luminaires should provide a lighting programme that complements or replaces the daylight provided by the sky-light above.
The pendant luminaires are equipped with light sources with varying colour temperatures from 2700K warm white to 6500K cool white, enabling the simulation of a daylight cycle.
They are controlled by Osram Optotronic Dali ballasts integrated into a KNX system with a KNX interface.
The plans for the building was originally designed by architect Ignaz Scheck in 1857.
Period details adorns the stairways and especially the executive foyer, which is a popular venue for receptions and celebrations.
The round arches above the cornice and the pillar reliefs on the wall are all highlighted. Additional, optionally switchable spotlights are directed downwards from the cornice in order to add a dramatic lighting effect for special events.
In one of the stairways, a bust of Austrian Emperor Franz Joseph I is permanently illuminated by a spotlight.
The entire lighting system can be operated via the KNX interface and the corresponding app on a smartphone or tablet.
The project was planned and executed by local companies. Based on the overall concept designed by the two Linz-based architects, Eva-Maria Bauer and Gerhard Stahl, the light design was developed by the independent lighting designer Christian Nopp from Austrian practice Das Licht. The electrical contractor is Linz-based Ransmayr Elektrotechnik.
Osram delivered that programming and commissioning of the eight lighting scenarios.
