Bank of America Tower at One Bryant Park is a 1,200 ft (366 m) skyscraper in the Midtown district of Manhattan in New York City, in the United States. It is located on Sixth Avenue, between 42nd and 43rd Streets, opposite Bryant Park. The US$1 billion project was designed by COOKFOX Architects, and advertised to be one of the most efficient and ecologically friendly buildings in the World.
It is the third tallest building in New York City, after One World Trade Center and the Empire State Building, and the fifth tallest building in the United States. Construction was completed in 2009. In October 2009, the building featured on episode 100 of the National Geographic Channel television series MegaStructures. In June 2010, the Bank of America Tower was the recipient of the 2010 Best Tall Building Americas award by the Council on Tall Buildings and Urban Habitat.
The tower's architectural spire is 255.5 ft (77.9 m) tall and was placed on December 15, 2007. The building is 55 stories high and contains 2,100,000 square feet (195,096 m2) of office space, three escalators and a total of 52 elevators manufactured by Schindler Group - 50 to serve the offices and one leading to the transit mezzanine below ground. Several buildings were demolished to make way for the tower. Among them was the Hotel Diplomat, a 13-story structure which occupied the site at 108 West 43rd Street since 1911, and Henry Miller's Theatre, which was rebuilt and reopened under its previous location. The building's tenants include Bank of America as the anchor tenant and Marathon Asset Management, and the tower's platinum LEED rating and modern column-free office space has helped to entice tenants from all over the city. The Bank of America Tower is considered a worldwide model for green architecture in skyscrapers. The building is sometimes referred to as The BOAT. (Bank Of America Tower)
The design of the building makes it environmentally friendly, using technologies such as floor-to-ceiling insulated glazing to contain heat and maximize natural light, and an automatic daylight dimming system. The tower also features a greywater system, which captures rainwater for reuse. Bank of America states that the building is made largely of recycled and recyclable materials. Air entering the building is filtered, as is common, but the air exhausted is cleaned as well. Bank of America Tower is the first skyscraper designed to attain a Platinum LEED Certification.
The Bank of America tower is constructed using a concrete manufactured with slag, a byproduct of blast furnaces. The mixture used in the tower concrete is 55% cement and 45% slag. The use of slag cement reduces damage to the environment by decreasing the amount of cement needed for the building, which in turn lowers the amount of carbon dioxide greenhouse gas produced through the normal cement manufacturing process. Each ton of regular cement produced creates about one ton of carbon dioxide in the atmosphere.
When comparing building height, only the structural height is used according to rules and regulations of the World Council on Tall Buildings. Currently, The New York Times Building and the Chrysler Building are tied for the position of the third tallest buildings in New York City. With the architectural spire included, the structural height of the Bank of America Tower is 1,200 ft (370 m), making it the third tallest building in New York City (after One World Trade Center and the Empire State Building).
