This 22-story tower in Dubai is not just a beautiful building boasting an unconventional design. It is also a very sustainable building, thanks to its innovative lace-like facade. The perforated concrete façade acts as a solar screen, while also allowing plenty of natural light to illuminate the office areas inside. Another role it has is that of a structural exoskeleton that absorbs the tower’s lateral forces and which also creates very efficient column-free interiors.
What’s even more important, is the fact that this unique façade contributes to achieving a lower energy consumption (a 30% reduction). This is possible thanks to the chimney-effect that is created by the 1-meter gap between the façade and the building’s glass surface. Here hot air can easily rise and thus reduce the need of supplementary cooling systems.
