NEW YORK — The Empire State Building, New York’s 1931 signature skyscraper, is undergoing a $20 million environmental- efficiency makeover to compete in the 21st century. The project, which includes building an on-site facility to remake all 6,500 windows in the 102-story tower, aims to cut energy use by 38 percent, said Ray Quartararo, director of development and project management for renovation supervisor Jones Lang LaSalle Inc.
Buildings account for 72 percent of the nation’s electricity consumption and emit 38 percent of its manmade carbon dioxide, according to the U.S. Green Building Council, a Washington-based organization that rates properties for their effect on the environment.
Empire State Building tenants will save on heating and air-conditioning bills after the renovation, Quartararo said. Bloomberg News
