Burj Khalifa is officially the World's Tallest Building at 828mts

Burj Khalifa has been officially declared as the world's tallest building at a height of 828.00 meters by the Chicago-based The Council on Tall Buildings and Urban Habitat (CTBUH).

The non-profit organization, in its statement, revealed that CTBUH has received and examined detailed drawings of the Burj Khalifa submitted by Emaar Properties, and can now confirm the official building height at 828 meters, and the title of The Worlds Tallest Building.

When the building was officially announced completion on 4th January 2010, Burj Khalifa surpassed the World's Tallest (Taipei 101) by 320 meters, an unprecedented increase of 61 percent.

The Burj Khalifa represents four major trends, with respect to location, function, structural material and height, in the current tall building construction category.

The trend of the world’s tallest buildings was dominated by the North American continent until the 1990s. But two decades later, the trend moved to Middle East and Asia, due to the dramatic increase in tall building construction in these regions. The Burj Khalifa is the third successive World's Tallest located outside North America.

As for the function of the building, the Burj Khalifa is the first mixed-use building to hold the World's Tallest title and is inline with the current tall building trends. At present only 20 percent of the world's 100 tallest buildings are for mixed-use.

For several years in a row, steel was the material of choice for tall buildings. However, at present composite, concrete and mixed-structure construction is more prevalent in tall buildings. Only 24 percent of the world's 100 tallest buildings at present have a purely steel structural system.

The height of super-tall structures keeps increasing. The number of completed super-tall now stands at 44, up from 11 in the year 1990. The figure is hoped to increase considerably over the next decade, with 70 projects 300 meters or taller under construction internationally.

Burj Khalifa has also been rated as World's Tallest in the primary height category of Height of Architectural Top the Council confirms. Burj Khalifa has also surpassed previous record heights in the Height to Tip category and Highest Occupied Floor category at 829.84 meters and 584.50 meters respectively.

Apart from this, the Burj Khalifa also contains record-breaking number of floors, at 163. The observation deck also becomes the second highest in the world at 452.1 meters.
