The site is of a very urban character, thus the
influences of the surrounding have great effect on the design.
Especially the emissions from the Karl-Marx Strasse, Bahnstrasse and the
noise of airplanes is to be eliminated. At the same time, a
representative plaza for the people shall be generated, delivering a
quality space, where people can stay, wait, talk and meet. This urban
place should also give a representative surrounding to the building. The
light and transparent elevation from the Karl Marx Strasse fits the
building with a positive presence and unique adress.The street as well as the urban space are guided
by the building, with its curved shape. The roof shades the offices and
collects rain water and solar energy. The creation of an attractive vis a
vis to the carpark will be continued in the 2nd building stage,
connecting at the northern part of the site. South of the building a
green park is arranged, giving possibility for wedding photos, resting
and a footwalk connection to the Brandenburger Platz.The building presents itself with a transparent
and welcoming architecture. All public offices are located at the
groundfloor and thus easy to access.The extraordinary low energy demand of the building (43%
below applicable german law) easily fulfills the requirements of the
EnEV 2012 and the EEWärmeG and results in an outstanding „Carbon
Footprint“ of only 26 kg CO2/m²a,
which is equal to a saving of 1/3 CO2, being about 45 tons per year in comparison to a modern
reference building. Consequently this forward thinking design creates
an enormous chance to receive a top rated building certificate.
