W35 - House of the European Union & Refurbishment of Schottenring 14
Renovation, building within the existing
As an in-fill project in a Gründerzeit city block and the revitalization of a listed building, the project responds to the contextual constraints of the UNESCO world heritage site. The design‘s facades adapt to the demands of neighboring buildings as well as the varying solar exposure.
A frame-in-solid construction, the south-western façade’s perforated aluminum louvers strike a self-contained appearance along Hohenstaufengasse. The reason for this is twofold: it is subject to extensive solar gain and the location prohibited a glass facade. In contrast, the north-eastern facade emphasizes transparency as it faces the historic Vienna Stock Exchange. The design decision opted for an elegant glass facade with sun shades, lamella screens integrated into the insulated glass panels.
The building’s structural system of diagonal stays has been pushed to the perimeter, expressing the design’s flexibility in its open floor-plan. The building’s transparency reflect the democratic ideals of the European Union, which utilizes the building’s first three floors as the “House of Europe“ and hosts events on the ground floor and in the glass roofed courtyard. The facades along the courtyard are slightly inclined by 6.5° to open the building towards the sky, ensuring optimal daylight conditions in the adjoining offices. The rooftop terraces feature extended views towards the city centre.
