Austro Tower

Austria’s fifth highest building is putting its faith in “energy from the river”

Vienna, 27th January 2021 – With 38 stories and a height of 136 meters, Vienna’s latest tower is attracting attention not only for its glazed façade, but also for its good timing. Because, despite any interim delays caused by the pandemic, the topping-out ceremony happened right on time. The approximately 43,400 m² of above-ground gross floor area include 28,000 m² of office space and a conference center, a canteen that is open to the public, and a café. The services commissioned from ATP Vienna include the architectural execution design and the integration of the tenant planning, the building physics, the LEED and ÖGNI platinum certification, and the design of the external areas.

ATP’s planning work is based on an existing design, which it has also developed further: “Thanks to the optimization – by SORAVIA together with ATP – we were able to transform half of the projected plant area on the 35th story into an elegant public space,” says ATP lead project manager Angelika Welkovits. The reorganization enabled this technical area, which was originally planned as a cooling plant room, to be given a more high-quality function. One success factor here was the switch from the conventional in-situ generation of cooling to “energy from the river”: Heating and cooling is provided by heat pumps that operate much more efficiently than usual due to the proximity of the Danube Canal and, hence, optimally benefit from the advantages of the location. As a result, the consumption of energy for cooling and heating can be kept very low. The space freed up on the 35th story is now used as a “lounge area” for employees and for meetings and includes an external area that is protected from the wind and enjoys a fantastic view.

Austro Control, ASFINAG, and SORAVIA plan to move their headquarters into the new landmark on the Danube Canal at the end of 2021.
