Bank of America Tower at One Bryant Park: New York City, NY
Ventilation in Wonderland

Ventilation in Wonderland
Why does one of the greenest skyscrapers in New York City also use more energy than its peers? Efforts to improve the energy efficiency of the building after it opened led the building operations team down a “rabbit hole”— a complex journey to investigate the energy ramifications of overventilation. One lesson? The building owner incorporated sustainable design into two subsequent projects, but did not pursue LEED certification. The authors also make the case for using metrics beyond site energy use intensity (EUI), such as source EUI, economic output, and tenant energy requirements, when evaluating a building's energy performance.
