WTC milestone: 100 floors and counting

One World Trade Center hit a milestone this month as the 100th floor was completed. When finished, the building and its antenna will rise a symbolic 1,776 feet.


Facts about One World Trade Center:

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.
