Future-oriented expansion of an established “City within the city”
The new buildings on the Mediencampus are a key component of the journalistic infrastructure, bringing together media production and the offices in one place, thus creating the technological and spatial conditions for the ORF's ongoing development going forward. The three-part complex echoes the horizontal lines of the surrounding buildings and is thus harmoniously integrated into the existing urban structure.

Transparency and openness for the working world of tomorrow
A central theme of the architectural design by Riepl Kaufmann Bammer Architektur is openness. The new buildings are designed as steel structures with the greatest possible proportion of transparent surfaces to allow for a flowing transition between inside and outside. The architect in charge, Paul Jung, explains: “Openness and transparency are seen as essential qualities for the work of a media company and are reflected throughout the entire architecture of the building. Our concept makes the space come alive and creates a positive atmosphere. The structural mass is relegated to the background, leaving open areas to define the image.” In this way, the new production and office buildings enjoy a lot of daylight, generous open spaces and areas that offer flexible use. In addition, they offer the possibility of going from the workplace directly to the media campus outdoors at any time – a future-oriented environment for all employees.
USED HYDRO CIRCAL 75R
OF CO2 SAVED
The chosen façade solution from WICONA is also outstanding because all elements are made from Hydro CIRCAL aluminium, which is produced with an end-of-life (EoL) recycling rate of at least 75%. This means that the aluminium used has already been utilised in construction elements such as windows, doors or façades and has been brought back into the loop. As Jörg Meiche, Sales Manager of Hydro Building Systems Austria, explains: “Hydro CIRCAL requires only 5% of the energy that would be required for primary aluminium production - while maintaining the same high quality. In addition, with 2.3 kg of CO2 per kg of aluminium, Hydro CIRCAL has one of the lowest CO2 footprints in the world.”
Innovative and sustainable building shell
In order to meet the high requirements for a productive indoor climate and maximum visual comfort in the workplaces, the architects decided in favour of the WICTEC Modul air curtain-type closed cavity façade. Measuring 2.5 x 3.5 m, the double-shell panel construction has an exterior baffle disc and an insulated interior façade. The façade panels have a cavity that is sealed off from the environment and continuously flushed with clean dry air, all of which is controlled from a central technical room and monitored 24 hours a day. This ensures that absolutely no condensation occurs in the space between the panels.
The sun protection, which is also built into the cavity, allows light to be directed individually and as required, and is also protected from weathering and dirt, thereby significantly reducing the time and effort required for cleaning. The closed cavity façade constructed by MBM Metallbau Mörtl (Carinthia) in close coordination with WICONA also excels in terms of energy efficiency and comfort. It achieves an outstanding thermal insulation of Ucw < 0,75 W/m²K and a very good sound insulation value of Rw > 45 dB. The elements are glazed with high-quality white glass, allowing plenty of natural and neutral daylight to penetrate deep into the rooms.
