In Bank of America's report on the construction of the building, it cited that the design of the building will make 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 system, which captures rainwater and reuses it. Bank of America also states that the building will be made largely of recycled and recyclable materials.
Another interesting innovation is that not only is air entering the building purified to an impressive degree, but the air exhausted is also cleaner, thus effectively making the tower a giant air filter for Midtown Manhattan. via Wikipedia
