For 10 poins, name this world's tallest building, formerly known as the Burj Dubai.
This building's interior features silver travertine flooring and Venetian stucco designed by Nada Andric for the firm Skidmore, Owings, and Merrill. This building's buttressed core design eliminates the twisting inherent in its Hymenocalis-inspired Y-shaped layout, and according to designer Bill Baker, its commissioners requested a significantly overengineered foundation, to accomodate repeated increases in its designed height.  Recent financial troubles in its home city may have been the cause of its opening-day renaming in honor of the President of the UAE and emir of neighboring Abu Dhabi.  For 10 poins, name this world's tallest building, formerly known as the Burj Dubai.
