Faits

  • Although the height from the esplanade at the main entrance is 180 meters, the tower measures 214.01 meters from ground, where a side entrance is located.
  • During renovation, 5,334 window panels will be replaced: this will improve the tower's heating performances by 50%.
  • After renovation, the tower should obtain HQE (High Environmental Quality) and BREEAM (Building Research Establishment Environmental Assessment Method) certifications.
  • Its Greek-cross shape affords an uninterrupted view to a maximum number of people inside.
  • The facade is covered with anodized aluminium breasting and tinted glass, materials that they harmonized into a single dark-green color.
  • In spring 1972 Parisian newspapers launched an anti-skyscraper campaign with the goal to shorten the height of the rising Tour Gan. Nevertheless, the building was constructed with its planned height.
  • After renovation, the tower's energy consumption should be reduced by 30%.
  • A nesting place for peregrine falcons will be installed at the top of the tower.
