The building, which dates back to the early 1980s, was brought up to date in terms of design and technology. The main focus of the renovation was the renewal of the building services and the design and technical modernisation of the office environment as well as the central rooms: reception, break rooms and cafeteria. Another focal point was the complete renovation of the façade, which gives the building a new, distinctive and unmistakable appearance. The glass slats are equipped with photovoltaic cells on the south-facing facades and are motor-controlled to adjust according to the position of the sun. They represent an innovative design element and simultaneously serve to provide shade and energy.
In terms of urban planning, the façade concept with the louvres creates a calming effect on the building, which is already relatively complex due to its shape. These vertically positioned lamellas adjust to the position of the sun. The thin-film cells are semi-transparent, so that there is sufficient shading, but a certain amount of transparency remains between the slats and even through the slats.
