Corporate Identity Set In The Right Light
The Architects Ingenhoven and Partner (Düsseldorf) and the statistics office of Werner Sobek Engineers have uniquely achieved the three-dimensional implementation of the aviation company.
The architecture of the Lufthansa Aviation Center (LAC) is support by large concrete surfaces whose appearance was made possible with high-quality casing. The LAC is situated on a narrow strip between the Motorway 3 and the aiport site, with a view of the take-off and landing runways. The large untreated exposed concrete surfaces within the interior of the building play a dominant role in the visual concept. The shell form of the LAC roofing has been designed according to the signet of the Lufthansa AG, the wing of a crane. The doubly-curved, 42m long and 28ch thick reinforced concrete shells above the office areas taper from 16 to 12m towards their periphary. They rest laterally on beams or walls of the central construction. A further highlight are the filigrane hollow concrete support pillars in the transparent atriums. The atriums with theme-oriented, planted inner courtyards serve as acoustic and immission buffers. The inner courtyards are designed with landscapes from the five continents. They symbolise the worlwide connections of Lufthansa.
The air-handling was implemented according to calculations by Klaus Daniels (HL-Technik), and creates a comfortable atmosphere and high quality work spaces for the 1,800 office workers. The energy used is two thirds less than a conventional building, and is due to the modular structure of the 'Low Energy Building'. Up to 1,800 workspaces will be available.
The demands stemming from the Tropp Lighting Design was to find a solution that uses daylight to a maximum, with avoidance of glare. And especially with respect to the theme-oriented inner courtyards, a dynamic, natural ambience should predominate the interior design.
Further requirements were: maximum energy efficiency, a high light output ratio and consideration of demands for VDU (computer screen) work.
Siteco installed a daylight system with micro sun shielding louvre in parts of the glazed roofing as a directionally-dependent sun and glare prevention system. BAP pendant luminaires with direct/indirect beam distribution (equipped with ELDACON® lighting technology, without louvres) were installed parallel to the facade. The luminaires come with high frequency gear and 2x1x54W T16 fluorescent lamping. Within the luminaire body further technical elements are incorporated such as fire detectors.
In transfer areas and special zones diverse downlights with various designs give light for orientation and for the optimal presentation of the interior design. Siteco Mirrortec® 400 double projectors illuminate the inner courtyards and serve as additional accent lighting.
