"Structural Design of the World s Tallest Building: The Burj - page 2 / 2





2 / 2

The 280,000m2 (3,000,000ft2) Tower and 185,000m2 (2,000,000 ft2) Podium structures are currently under construction and the project is scheduled for topping out in 2008. The Burj Dubai, currently the world’s tallest building, is the centerpiece of a large scale mixed use development comprised of residential, commercial, hotel, entertainment, shopping and leisure outlets with open green spaces, water features, pedestrian boulevards, a shopping mall, and a tourist-oriented old town.

The design for the 270,000m2 tower combines historical and cultural influences with cutting edge technology to achieve a high-performance building that, which will set the new standard for development in the Middle East and become the model for the future of Dubai.

When designing the Burj Dubai, the design team looked to the sky for sustainable elements. In the extreme hot and humid climate of Dubai, the temperature between the ground (46.1ºC or 115ºF) and the top of the building (38ºC or 100ºF) can vary up to 8ºC (or 15ºF). Satellite data was used to predict the humidity drop with altitude (up to 30 percent reduction in humidity between the top and bottom of the building), and analysis was performed to study the air density drop up the building (up to 10 percent). SOM’s “sky sourced” sustainability innovations will result in substantial energy savings.

The Burj Dubai also has one of the largest condensate recovery systems in the world, capturing up to fourteen Olympic-size swimming pools of water per year, and one of the highest chilled water pressures ever used in a building to maximize efficiency. The tower is one of the first to utilize an active stack effect control in a super tall building to minimize energy loss.
