. The Burj Dubai has officially completed as the World’s Tallest Building. After years of speculation, the building’s owner –developer, Emaar Properties, has finally revealed to the public the building’s total height, which had previously been a tightly kept secret.

Announced during the building’s opening celebration on Monday January 4th, 2010, the height was revealed on a digital projection amidst a spectacular fireworks and water show. The height of 828 meters (2,717 feet) still has to be ratified by the CTBUH upon receipt of official architectural drawings. The 828 meter height reflects the Council’s recently changed height criteria, which now measures the height of a building from the lowest, significant, open-air, pedestrian entrance. For the Burj this means that the height is measured from the office entrance and adds about 10 additional meters to the height.

Also announced at the opening ceremony was the building’s official name change. Previously known as the Burj Dubai, the tower has now been renamed as the Burj Khalifa. A mixed use development, the Burj Khalifa will house residential apartments, offices, and an Armani hotel. It was recently announced that the tower’s first tenants will be moving in as early as February 2010.
