What makes the Bank of America Tower at Bryant Park special in today's Kyoto conscious world, it's unique selling point if you will, is the fact that it is effectively a giant air filter. The air entering the building is purified and the air exhausted is even cleaner. That is on top of a host of other environmentally friendly features. The concrete used in the construction of the building is 55% cement and 45% slag, a by-product of blast furnaces. Temperature control in the tower is also environmentally friendly. Floor to ceiling insulating glass maximises natural light as well as containing heat and the tower also reuses rainwater. The building also incorporates an old technology, ice phase transition, which produces and stores ice to help cool the building in peak
periods. There is also a 4.6 mega watt onsite cogeneration plantwhich reduces the significant electrical transmission losses that are typical of central power production plants. The tower also features an underfloor air system which provides the occupants with the ability to control the temperature in their own space via multiple air column units which also improves air ventilation effectiveness. All of these features are evidence that New York is still at the forefront of world skyscraper technology with one of the most environmentally friendly towers in the world.
