Although under construction, this skyscaper IS listed already on Emporis, See (visit link
When it is completed, this building will be the tallest in the US at standing at a height of 1,776 feet. Construction is expected to be completed in 2013.
The design includes 2,600,000 square feet (242,000 m2) of office space, as well as an observation deck, parking and broadcast and antenna facilities. David Childs is the architect.
The site will include a 911 Memorial and Museum.

" ONE WORLD TRADE CENTER NO. 1 IN N.Y.
Unfinished monolith built to replace the twin towers rises to claim title of city’s tallest skyscraper
One World Trade Center, the monolith being built to replace the twin towers destroyed in the Sept. 11 attacks, claimed the title of New York City’s tallest skyscraper on Monday, as workers erected steel columns that made its unfinished skeleton a little over 1,250 feet high, just enough to peek over the roof of the observation deck on the Empire State Building.
City officials and iron workers applauded as the first 12-ton column was hoisted onto the tower’s top deck.
“This project is much more than steel and concrete. It is a symbol of success for the nation,” said David Samson, chairman of the Port Authority, the agency that owns the World Trade Center.
Clear skies afforded an immaculate 360-degree view from the top, although it wasn’t easy getting up there. After riding an elevator to the 90th floor, a small group of officials and journalists had to climb three steep ladders to reach the top platform, which was encircled by blue netting along the perimeter.
The milestone is a preliminary one. Workers are still adding floors to the building once called the Freedom Tower. It isn’t expected to reach its full height for at least another year, at which point it is likely to be declared the tallest building in the U.S., and third tallest in the world.
Those bragging rights, though, will carry an asterisk.
Crowning the world’s tallest buildings is a little like picking the heavyweight champion in boxing. There is often disagreement about who deserves the belt.
In this case, the issue involves the 408-foot-tall needle that will sit on the tower’s roof.
Count it, and the World Trade Center is back on top. Otherwise, it will have to settle for No. 2, after the Willis Tower in Chicago.
“Height is complicated,” said Nathaniel Hollister, a spokesman for The Council on Tall Buildings and Urban Habitats, a Chicago-based organization considered an authority on such records.
Experts and architects have long disagreed about where to stop measuring super-tall buildings outfitted with masts, spires and antennas that extend far above the roof.
Consider the case of the Empire State Building: Measured from the sidewalk to the tip of its needlelike antenna, the granddaddy of all skyscrapers actually stands 1,454 feet high, well above the mark reached by One World Trade Center on Monday.
Purists, though, say antennas shouldn’t count when determining building height.
An antenna, they say, is more like furniture than a piece of architecture. Like a chair sitting on a rooftop, an antenna can be attached or removed. The Empire State Building didn’t even get its distinctive antenna until 1952. The record books, as the argument goes, shouldn’t change every time someone installs a new satellite dish.
Excluding the antenna brings the Empire State Building’s total height to 1,250 feet. That was still high enough to make the skyscraper the world’s tallest from 1931 until 1972."
