"Eighty percent of the energy consumed in New York City is consumed by buildings," says Malkin, who is president of Malkin Holdings, part-owner of the Empire State Building. "Not by cars, not by buses, not by taxis, not by subways, not by trains. Even more interestingly, 20 percent of the buildings consume 80 percent of that energy. So 64 percent of all energy consumed in New York City is consumed by 20 percent of the buildings. That really took me by surprise."
