Reference Project

One World Trade Center New York (USA)

Sustainable design was a central theme to One World Trade Center’s development with strict requirements for the replacement of portland cement with recycled materials.

Soaring to a height of 1,776 feet (540-meters), the 2.6-million-squarefoot (242,000-square-meter) skyscraper known as One World Trade Center in the lower Manhattan district of New York City is a marvel of design and engineering. Construction of the building, previously called the Freedom Tower, began in April 2006 and at the time was the tallest building in the United States.
