The Bank of America Tower at One Bryant Park is a 1,200 ft (366 m) skyscraper located on Sixth Avenue, between 42nd and 43rd Street, opposite Bryant Park in midtown Manhattan. The building was designed by Cook+Fox Architects to be one of the most efficient and ecologically friendly buildings in the world. It uses technologies such as floor-to-ceiling insulating glass to contain heat and maximize natural light, and an automatic daylight dimming system. The tower features a graywater system, which captures rainwater and reuses it. The green building is made largely of recycled and recyclable materials such as steel and drywall, and low-VOC products. Air entering the building will be filtered, as is common, but the exhausted air will be cleaned as well. The building includes a five-megawatt cogeneration plant, ice storage plant, green roof areas and waterless urinals. It is the third tallest building in New York City, after One World Trade Center and the Empire State Building, and the fourth tallest building in the United States. Construction was completed in 2009.
