Although the new glass façade of the ARZ was already able to counteract overheating of the building, the client opted to fit the window fronts with external venetian blinds. Our office was commissioned to design the colour scheme of the solar shading and chose a gradation in five different shades of grey, intended to reflect the acceleration and braking of the vehicles on the Südring, where 50,000 cars pass by every day. In this way our office accompanied the conversion of the headquarters of the Allgemeines Rechenzentrum in Innsbruck and, together with the clients, developed a new façade including climate concept, solar shading and glare protection. Since the merger of RZW and VDG in 1993, the ARZ, with its two sites in Innsbruck and Vienna, has made a well-known and respected name for itself in Austria as a centre of competence for IT services in the banking sector, but also for hospitals and public administration.
