Details

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 2100000 square feet (195,096 m²) of office space, three escalators and a total of 51 elevators manufactured by Schindler Group

Environmental features

The design of the building makes it environmentally friendly, using technologies such as floor-to-ceiling insulating glass to contain heat and maximize natural light, and an automatic daylight dimming system. The tower also features a greywater

 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

A greenhouse gas is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect. The primary greenhouse gases in the Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone...

 produced through the normal cement manufacturing process. Each ton of regular cement produced creates about one ton of carbon dioxide in the atmosphere.

Temperature control and the production of some of its energy are accomplished in an environmentally friendly manner for the tower. Insulating glass reduces thermal loss, lowering energy consumption and increasing transparency. Carbon dioxide sensors signal increased fresh air ventilation when elevated levels of carbon dioxide are detected in the building.
Conditioned air for the occupants is provided by multiple air column units located in the tenant space that deliver 62 degree air into a raised access floor plenum. This underfloor air system provides users with the ability to control their own space temperature as well as improving the ventilation effectiveness. When building churn occurs, workstation moves can be performed easier with lower cost and less product waste.

The cooling system produces and stores ice during off-peak hours, and allows the ice to melt to help cool the building during peak load, similar to the ice batteries in the 1995 Hotel New Otani in Tokyo, Japan. Ice batteries have been used since absorption chillers first made ice commercially available 150 years ago, before the invention of the electric light bulb.

Water conservation features in the tower include waterless urinals, which are estimated to save 8000000 gal of water per year and reduce CO2 emissions by 144000 lb (65,317.3 kg) per year (as calculated with the Pacific Institute

Construction incidents

Since 2006, materials have fallen from the building on at least six occasions.
  • August 12, 2008: A 1500 pounds (680.4 kg) glass panel fell onto a sidewalk. Two people suffered minor injuries.

  • September 17, 2008: A debris container fell, shattered a panel of glass facade, and caused several pieces of glass to fall from the 50th floor to the sidewalk/street (West 42nd and Sixth Avenue) around 3PM. No one was injured.
