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.
The building’s internal configuration is largely determined by the
need of compact traffic areas and office space allowing for maximum
flexibility in organisation. 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 part function as a
