A number of levels halfway up and off the main axis are what make up the striking cubature of the Omniturm. Designed by Danish architect Bjarke Ingels, behind the architectural accent the special mix of uses of the high-rise: the “hip curve” arching out of the façade characterizes the living area from the 15 th to the 22 nd floor, which stands out visually from the linearly stacked floors with offices and public uses. The Omniturm is the first skyscraper in Germany to combine work, living and public areas in its spatial program. The 45 levels accommodate 44,000 m 2 of offices, 8,200 m 2 of rental apartments and a further 1,700 m 2 of restaurants and shops. Based on the Latin «omnia» - «everything» - this is what the name of the tower expresses. The shifting of the axes on the residential floors also has a positive effect on the floor plans: This is how the offset balconies of the apartments were created. From a static point of view, however, the “hip swing” was a challenge - which the planners solved with elegantly inclined supports. The high-strength steel reinforcement connected to the building core ensures maximum stability. Sun protection, daylight and filigree corners A surprising amount of daylight gets into the interior of the high-rise building through the 15,000 m 2 of solar control glass. The COOL-LITE ® XTREME 70/33 from SAINT-GOBAIN used for all office floors is a triple solar control glass with an excellent selectivity of 2.12. With its light transmission of 66–70% (depending on the glass structure), it brings plenty of natural light into the building and protects the user with its solar factor of 0.32–0.33 (also depending on the glass structure) and its Ug value of 1.0 W/m 2 K from too much solar heat.
