    Sustainable Skyscraper!

    The Bank of America Tower at One Bryant Park (42nd Street and 6th Avenue) represents the cutting edge in sustainable commercial construction. Completed in 2010, this LEED Platinum 2.1 million square-foot 51-story skyscraper utilized sustainable construction practices and the building’s design boasts a number of sustainable elements worth highlighting:

    • State-of-the-art 4.6 Megawatt on-site co-generation power generation facility. By having the power-plant on site the building reduces efficiency losses that would occur over long-distance electricity transmission; in addition, it utilizes the waste heat from combustion of natural gas to generate electricity for heating and cooling! This facility is ~3x as efficient as a traditional coal plant!!
    • ~4,545 square foot green roof that helps mitigate storm-water run-off (i.e., on very rainy days excess rain water ends up in sewerage treatment plants and can cause a spill-over of untreated rain / sewerage into the rivers and the harbor. Green roofs and storage tanks help to mitigate this overflow effect by reducing the amount of water flowing through the system).
    • Four storage tanks collect 69,000 gallons of rain water which is filtered and used as “gray water” for cooling the building and flushing the toilets.
    • Recycling of all sink water from the building for use in the building’s toilets, reducing the building’s water demands.
    • Waterless urinals conserve 3.4 million gallons of water each year.
    • Ice storage to reduce peak demand energy! The building makes ice every night when electricity prices are low (i.e., because there is less competition for electricity during hours when not as many people are using it) and utilizes this ice to cool the building during the day, thereby reducing strain on the electric grid during peak demand hours.
    • 35% of the construction materials utilized were recycled materials.
    • 85% of construction debris was recycled.
    • 20% of construction materials were sourced from withing a 500-mile radius (i.e., reducing the transportation distance of the construction materials reduces their carbon footprint).
