Taking a look into One World trade centre

It has almost 12 years since the terrorist attacks that brought down the twin towers of the World Trade centre in New York City. With the original sights of the towers now serving as a memorial to those who lost their lives, work began on the city’s newest skyscraper in 2006. Known colloquially as ‘Freedom tower’, One World Trade Centre is now the tallest building in New York, surpassing the Empire State Building to dominate the city’s famous skyline. With the process of construction coming to an end I have had a look at some of the defining features of the primary building in the newly constructed World Trade Centre complex.

Symbolic height
One World Trade centre is the tallest building in the western hemisphere and the third tallest building in the world by pinnacle height. Its spire reaches 1,776 feet, a highly symbolic reference to the year of the American declaration of independence from Britain.  The spire is in fact a broadcasting antenna that is encased in radome, a protective enclosure that is transparent to radio waves, and is also guarded by a decorative steel spire. Topping off the impressive new building is a slow rotating beacon at the peak of the spire that will flash out Morse code for the letter N, standing for New York.

Safety features
The stairwells in the building are extra wide and will be pressurised with their own air supplies. There are multiple backups for emergency lighting and there is even concrete protection for the building’s sprinklers.  The tower’s impressive communications cables will alert local authorities of any incidents with occupants being provided with collection points on each floor where they can wait for help. Fire-fighters and other emergency services will have the best possible access via a dedicated stairwell if an emergency does occur.

Sustainable design
A green approach has been central to the development of One World Trade Centre, and it will be the most environmentally sustainable building of its size in the world. It is expected to draw as much a as 70% of its power from green energy and will host to several sustainable features. Fuels cells will provide clean energy to the tower, and the waste heat output from this fuel cell system will be recycled to use for hot water and heating in the buildings podium and the entrances. Renewable energy sources such as wind and hydro power are also being utilised. Recycled rainwater will be used to cool the building, which was constructed of 75% post-industrial recycled equipment.

Fast elevators
Elevator shafts run through the centre of the building, surrounded by 1 meter thick concrete designed to withstand heavy impacts. The elevators will be the fastest in the Americas and a total of 71 will operate throughout the building’s core, taking employees and visitors to various floors at a speed of 610 metres per minute. Besides being fast, the elevators will feature an intelligent recognition system that will identify passengers and only take them to the floor for which they have authorisation!

The tower is set to open later this year and provides lower Manhattan with another building to add to its iconic skyline.
