Burj Al Khalifa Sheikh Zayed Road Flyovers 2011

 

Sheikh Zayed Raod and Burj Al Khalifa

There are unconfirmed reports of several planned height increases since its inception. Originally proposed as a virtual clone of the 560 m (1,837 ft) Grollo Tower proposal for Melbourne, Australia’s Docklands waterfront development, the tower was redesigned by Skidmore, Owings and Merrill (SOM).Marshall Strabala, an SOM architect who worked on the project until 2006, in late 2008 said that Burj Khalifa was designed to be 808 m (2,651 ft) tall.

The design architect, Adrian Smith, felt that the uppermost section of the building did not culminate elegantly with the rest of the structure, so he sought and received approval to increase it to the current height.It has been explicitly stated that this change did not include any added floors, which is fitting with Smith’s attempts to make the crown more slender.

The air conditioning system draws air from the upper floors where the air is cooler and cleaner than on the ground. At peak cooling times, the tower’s cooling is equivalent to that provided by 13,000 t (29,000,000 lb) of melting ice in one day. The condensate collection system, which uses the hot and humid outside air, combined with the cooling requirements of the building, results in a significant amount of condensation of moisture from the air. The condensed water is collected and drained into a holding tank located in the basement car park; this water is then pumped into the site irrigation system for use on the Burj Khalifa park.
