  • 30. The mixture used in the tower concrete is 55% cement and 45% slag( a byproduct of blast furnaces). The use of slag cement reduces damage to the environment (One ton of cement produced emits about one ton of carbon dioxide into the atmosphere.)

  • 31. Rain water collection
    combine roof-captured rainwater with the grey water from the building's washroom sinks, condensation from the tower's air conditioning and from the steam purchased from the utility company ConEdison used to flush the toilets and run evaporation panels that help cool the building.

  • 34. air filter for NYC
    "We will take in four times as much air as New York codes require, and the air we expel will be much cleaner than what we take in."
    The greater volumes of air make it possible to flush more VOCs (volatile organic compounds) out of the air, diminishing the likelihood of "sick building syndrome" sometimes blamed on imperfect air filtration systems.
    He says that people working in the Bank of America Tower will breathe air cleaned of 95 percent of its particulate matter instead of the 35 percent typical in office buildings.

  • 35. “Cogeneration (also combined heat and power, CHP) is the use of a heat engine or a power station to simultaneously generate both electricity and useful heat(…). By-product heat at moderate temperatures (212-356°F/100-180°C) can also be used in absorption chillers for cooling”
    (source: wikipedia.org).
    Cogeneration
    A 4.6-megawatt fuel-cell cogeneration plant provides part of the base-load energy requirements.
