Hồ Hải Phong Soaring 828 meters above the
metropolis of Dubai, the Burj Khalifa is the world’s tallest building. The
design for the 162-story tower combines local cultural influences with
cutting-edge technology to achieve high performance in an extreme desert
climate.
The centerpiece of a large
mixed-use development, the Burj Khalifa contains offices, retail space,
residential units, and a Giorgio Armani hotel. A Y-shaped floor plan maximizes
views of the Arabian Gulf. At ground level, the skyscraper is surrounded by
green space, water features, and pedestrian-friendly boulevards.
The tower’s overall design
was inspired by the geometries of a regional desert flower and the patterning
systems embodied in Islamic architecture. Built of reinforced concrete and clad
in glass, the tower is composed of sculpted volumes arranged around a central
buttressed core. As the tower rises from a flat base, setbacks occur in an
upward spiraling pattern, reducing the building’s mass as it reaches skyward.
At the pinnacle, the central core emerges and forms a spire.
Beyond its record-breaking
height, the Burj Khalifa incorporates new structural and construction
efficiencies to reduce material usage and waste. These include a “sky-sourced”
ventilation system, in which cool, less humid air is drawn in through the top
of the building. The tower also has one of the largest condensate recovery
systems in the world.
