Who says you can’t learn new tricks in your golden years? At 80 years old, the Empire State Building is already one of the world’s tallest buildings, and now reinventing itself to be one of the world’s most energy efficient. By 2013, changes to the landmark are expected to cut energy use by 38% a year – saving nearly $4.5 million annually.

In fact, while people are often scared off by the cost of retrofitting older buildings – with the new savings, supervisors expect to pay back those costs in only 3 years. Our specialist, Anthony Malkin, president of Malkin Holdings, one of the owners of the Empire State Building, says cost-savings is just one of the benefits. (We officially appoint him a community hero for sustainable energy!)
