Freedom Tower’s Design • The building is to both mark the site of the old towers and be a beacon for the

future, like a lighthouse. Also it has to function well• The Wedge of Light is created by ''the effect of the facades of the building

reflecting the light back into the plaza.'' The effect is not linear, he said, but ''a three-dimensional phenomenon'' that is ''about the ambience of light and the reflections of light between the buildings.''

The final design consisted of simple symmetries and a more traditional profile, intended to bear comparison with selected elements of the contemporary New York skyline. The tower's central spire draws from precedents such as the Empire State Building and the Chrysler Building, and is also visually reminiscent of the original World Trade Center twin towers, rather than being an off-center spire intended to echo the Statue of Liberty.

The ultra-modern design of One World Trade Center is an innovative mix of architecture, safety and sustainability. The building's simplicity and clarity of form are timeless, extending the long tradition of American ingenuity in high-rise construction. One World Trade Center will be a new visual landmark for New York and the United States.Its structure is designed around a strong, redundant steel frame, consisting of beams and columns.

Americas tallest building- a glass and steel symbol of resiliency, as well as scientific and architectural triumph.

1. BOMB PROOF BASE :The building's footprint is a 200-foot (61 m) square with an area of 40,000 square feet (3,700 m2).The tower rises from a 185-foot (56 m) windowless concrete base till 19th floor.

2. Bunkerlike base known as podium can withstand force of 680 kg truck bomb and covered with prisimatic glass. Made of Icrete, can withstand 14,000 sq ft. Walls are now covered in "hundreds of pairs of 13-foot vertical glass fins set against horizontal bands of eight-inch-wide stainless-steel slats.

3. From the 20th floor upwards, the square edges of the tower's cubic base are chamfered back, transforming the building's shape into eight tall isosceles triangles, or an elongated square antiprism. Near its middle, the tower forms a perfect octagon in-plan, and then culminates in a glass parapet whose shape is a square oriented 45 degrees from the base.

4. A 408-foot (124 m) sculpted mast containing the broadcasting antenna –At night, an intense beam of light will be projected above the spire, being visible over 1,000 feet (300 m) into the air above the tower.

5. LED lights behind the panels will illuminate the base at night.6. ELEVATORS:A total of 71 elevators will operate in the core, go up

and down at 2000 ft per minute. The concrete surrounding the shaft is 3 feet thick. Buildings perimeter is formed by steel girder.

Also with the help of card one has to be floor specific and chose.

1. SAFETY SPECS:BOMB PROOF BASE: The stairwells will get their share of formidable concrete along with all the buildings safety systems, including exhaust, ventilation shaft, electrical and plumbing columns. Even the sprinklers will have concrete guards.

2. THE GLASS GLOWN OUTSIDE: The glass that will wrap around 1 WTC is made up of Teflon, The special glass is blast resistant.

3. SUSTAINABILITY:. Much of the building's structure and interior is made from recycled materials, including gypsum boards & ceiling tiles, about 80 percent of its waste products are also being recycled.

4. The building will implement a rainwater collection The building's PureCell phosphoric acid fuel cells will generate 4.8 Megawatts (MW) of power, and its waste steam will also help generate electricity.The tower will also make use of off-site hydroelectric and wind power.[157] The windows are made of an ultra-clear glass which allows maximum daylight to pass through, while interior lighting is equipped with dimmers that automatically lower the lights on sunny days, thereby reducing energy costs.Like all of the new facilities at the World Trade Center site, One World Trade Center will be heated by steam, with limited oil or natural gas utilities located on-site.

5. It is expected to receiveLeadership in Energy and Environmental Design (LEED)Gold Certification, making it one of the most environmentally sustainable buildings of its size in the world.

SPIRE- The most attractive feature of the building

ONE WORLD OBSERVATORY:This ultimate observation deck, to be called One World Observatory, will take visitors on an inspirational journey about the history of this iconic structure.The spectacular sight-seeing venue is projected to draw an estimated 3.8 million annual visitors to the top of the tallest structure in the Western Hemisphere. The 120,000 square foot facility is scheduled to open in early 2015 and will occupy floors 100 through 102, approximately 1,250 feet above street level.Visitors will board one of five dedicated state-of-the-art elevators that will be among the fastest lifts in the world to ascend to the top of the building in approximately 60 seconds. The venue will feature cutting-edge digital technology, dining options, a gift shop, special events space and a theater where visitors will learn about the building of One World Trade Center.
