2226 ROBIN
Seestadt Aspern, Vienna

Mixed use


The ensemble contributes substantially to life in the new city quarter. It incorporates the urban space and its traffic flows. It is highly flexible in its use, forward-looking in its energy efficiency.


Currently under construction, Seestadt Aspern is a Vienna quarter that combines sustainability, quality of life and economic dynamism. Plans include multifunction structures designed with the 2226 concept in mind – that is, buildings that dispense with air conditioning technology and highlight energy solutions in these ambitious surroundings


The project continues Aspern’s ideas with a site-specific interpretation, wherein precise spatial transitions lend transparency to the superordinate block structure. The ensemble’s layout is designed for accessibility – open to the urban environment, closed to the main traffic arteries. The approx. 3,600-m2 site will comprise three buildings containing mainly office space along with areas for commercial use, restaurants and studios.

Varied integration into overall context
The structures take formal cues from urban development: a row of columns connects the two buildings towards the wide road; trees will be planted behind them. The result is a spatial continuum of façades with an added element of surprise, thanks to the juxtaposition of columns with an unexpected a glimpse of green trees beyond them. The design consciously relativizes a hermetic insularity.

“The building concept manifests in use-neutral areas and energy efficiency without the use of building services – derived from the possibilities of architecture.”

Jakob Pesendorfer


Besides 2226, the distinctive building concept manifests in use-neutral areas that highlight a further aspect of sustainability. These open plan areas extend from the load-bearing exterior walls to the service core at the centre of the structures. Free of further load-bearing elements, they can be flexibly adapted meet different needs and accommodate changes in the market. 

2226 construction: a new quality in sustainability
The buildings make do without heating, cooling and ventilation systems, significantly reducing energy consumption. The name “2226” stands for the target temperature range inside a building – the universally accepted perfect temperature between 22 and 26º C. This is achieved through the means of architecture: through the high thermal storage mass that comes with solid, plastered brick walls, balanced room proportions and window surfaces. Heat comes courtesy of the people themselves, IT equipment and lighting, whilst sensor-controlled ventilation panels provide cooling and ventilation.


The ensemble has a striking aesthetic energy as well, with a timeless beauty that contributes to its longevity.


The project emphasises sustainability in a way that will have a long-term impact: conceptually, aesthetically and in day-to-day life.
