Sumit Singhal loves modern architecture. He comes from a family of builders who have built more than 20 projects in the last ten years near Delhi in India. He has recently started writing about the architectural projects that catch his imagination. ORBI tower in Vienna, Austria by ZECHNER / ZECHNERNovember 8th, 2017 by Sumit Singhal
Article source: ZECHNER / ZECHNER After winning the 2013 architectural competition, construction started in 2015, and the office tower was completed in 2017. The project developers were Wiener Stadtwerke Holding AG, and STC – Swiss Town Consult AG.  Image Courtesy © Pierer.net

It takes seven minutes to travel from the 115 m high tower to St. Stephen’s Square (Stephansplatz) by urban transport. The airport is just a 12 minute carried away. The tower boasts 21 600 m² of office space for rent on 26 floors. The project provides for a tower rising from a trilobate, an orbiform, which together with the existing neighbouring tower forms a gate-like close to the TownTown-Piazza while at the same time also acts as a salient head in the southeast direction. One broadside of the trilobate points towards the Piazza in the direction of the entrance to the underground station thus marking the main access to the building and defining an attractive forecourt. One narrow side is oriented towards the east and acts as a curve to the motorway junction.

The building’s aerodynamic base form with its curves drawn into space through its horizontal structuring is engaged in a dialogue with the curves of the adjacent motorway section. In contrast to the crystalline structure of the neighbouring buildings the project acts as a mediating design element to this transport infrastructure object. The facade is a band double facade offering mobile, wind-protected external solar protection. The colour of the glazed parapets gradually changes from bottom to top so that the building shows a soft colour progression from dark to light grey over its entire height. This optical effect “dematerialises” the building as it rises further up.

This requires an optimised structural and installation core at the centre with a circumferential, freely usable space. Essential design criteria are related to the claim for a sustainable building, taking ecological factors into account. The building will been certified according to ÖGNI. The focus is on an efficient use of energy, water, and other resources, protection of user health, and a reduction of waste and undesired emissions. For the benefit of energy efficiency the use of passive systems is at the centre to reduce the necessary share in technical systems to a necessary extent and thus keep lifetime costs low. The activated concrete ceilings in the building parts function as a release system for heating and air conditioning.

On the ground floor public facilities and catering establishments are located next to the lobby also stretching through to the first floor. Upper floors 2 to 25 are designed as individually divisible office spaces. The selected building depth and configuration of the inner cores allow for a wide range of different forms of office organisation providing maximum flexibility. Thanks to its high flexibility the reversible office strategy has proved to be an optimised concept for investors which is easily adaptable to the wishes of individual users and as such generates high sustainability.

Rather than standard desks and office cabinets the furniture recalls flats, restaurants, or recreational premises. Chill-out zones and creative areas alternate with computer work stations. In the emergency exit staircase bright colours and posted slogans encourage stair climbing, athletic success can be verified on each floor with heart beat sensors.

As architects or general planners the firm has implemented numerous projects of different sizes and functions at home and abroad, from residential complexes to office towers, from hotels to railway stations. Projects include the airport tower in Vienna, the main railway station in Graz, the new ÖBB group headquarters, hotel and residential buildings in Viertel Zwei, and the ORBI Tower.
