Siemens Real Estate

New Office Building

GreenBuilding and Geothermics

Siemens is seeking the GreenBuilding Certificate for the building. This means that the primary energy needs of the building must be at least 25% below the values of the Energy Saving Ordinance 2007. All rational alternatives were examined (e.g. geothermal, heat storage, solar-thermal, use of utility water and daylight) and rated in terms of their economic viability. The building was equipped with five suction and four recharging image wells for use of groundwater for heating and cooling. In addition, 30 geothermal sensors were installed. The entire system runs via a plate heat exchanger and a heat pump.


In addition to earlier work (2001) for Siemens in Mülheim an der Ruhr, aib was engaged for the planning of a medium-load hall and further expansion of the office capacities for around 1,000 employees.


Urban Planning

aib’s urban planning concept provides for the medium-load hall to take up the alignment of the existing heavy-load hall and to be arranged axial-symmetrically to the closing axis. The office building is aligned to the medium-load hall and forms a forecourt to receive visitors.
