Draft Building

Burj Dubai will become a city in the city - with their own lawns, boulevards and parks. The total cost of construction - about $ 4.1 billion The author - an American architect Adrian Smith, already has experience in designing such facilities (in particular, he participated in designing a skyscraper in China Jin Mao height of 420 m). As a general contractor building construction unit was selected the South Korean company Samsung, which had previously participated in the construction of Petronas twin towers-in Kuala Lumpur.

A man tower, which will be erected above the main building will have, apart from a decorative function, and even communications, as will be equipped with the necessary telecommunications equipment.

Features of the building

The construction of a skyscraper began in 2004 and comes at a speed of 2-3 floors a week. At the moment, at its creation took about 320 thousand m³ of concrete and more than 60 thousand tons of steel fittings. Upon completion of 160 floors concrete works cease, and construction will be carried out from the metal structures. Fire system will allow the building to evacuate all its inhabitants for no more than 32 minutes.

The tower will be fully self-generate electricity for itself: it will be used 61 - metre turbine rotating wind, as well as an array of solar panels (partially located on the walls of the tower), with a total area of about 15 thousand m ². In addition, the building is equipped with special protection from the sun and reflective glass panels, which will reduce heat inside the premises (in Dubai are the temperature to 50 ° C), which reduces the need for air-conditioning systems. For air conditioning in the skyscraper used convection system, overtakes air upwards throughout the height of the tower, which will be used for cooling sea water and underground cooling modules. While that the air temperature in the building will be about +18 ° C.
