The iconic One World Trade Center – forged from ArcelorMittal steel – has been named 2015’s best tall building in the Americas.
Constructed using more than 12,500 tonnes of HISTAR® beams and columns produced in Luxembourg, the skyscraper has been named the best tall building on the American continent by the Council on Tall Buildings and Urban Habitat (CTBUH).
With strong sustainability and aesthetic credentials, One World Trade Center scored highly in four judgement criteria, which included impact on in habitants and their quality of life, relevance to the needs of the community, and economic vitality to the occupants, owner, and community.
An overall winner for CTBUH’s “Best Tall Building Worldwide” accolade will be selected on November 12 in Chicago. One World Trade Center will be in competition with the three other regional winners, including CapitaGreen in Asia and Australasia, Bosco Verticale in Europe, and Burj Mohammed Bin Rashid Tower in the Middle East and Africa region.
Safe, sustainable steel
The presence of ArcelorMittal’s HISTAR® beams in the tower’s structure significantly contributes to One World Trade Center’s sustainability credentials. Structural steels offer high material efficiency, and hot-rolled sections constitute the most recycled building material in the world.
In addition to meeting the Trade Center’s rigorous safety and sustainability criteria, HISTAR® also met designers’ requirement for lightweighted and economical structures. Hot-rolled H-beams in HISTAR® grades enable the construction of innovative and competitive structures and are highly-suited for high-rise buildings.
One World Trade Center’s so-called “Freedom beams” are made out of HISTAR® grade 65 steel and measure 9-17 metres, weighing up to 1.1 tonnes per metre. They were produced at ArcelorMittal Differdange – the only steel mill in the world able to produce these beams.
Burj Khalifa – another building made with ArcelorMittal steel beams – was awarded “Best Tall Building Middle East & Africa” in 2010, and went onto receive CTBUH’s “Global Icon” award.
