After Superstorm Sandy, when most of lower Manhattan was dark, NYU stayed warm and lighted from its cogeneration plant. We learned then the value of building resilience. Combining sustainability with resiliency brings in many more benefits. Insulating and air sealing buildings keeps them warm longer if a power outage occurs in freezing weather. Energy efficient lighting and appliances extend the runtime of generators’ fuel tanks. And reducing our carbon footprint helps mitigate global climate change that makes natural disasters more common to begin with.
