Empire State building set for green makeover

The Empire State building is going "green" in a project that will save about $4.4 million a year on energy.

Completed in 1931, the Art Deco building immortalized in the film King Kong has been named by the American Society of Civil Engineers as one of the Seven Wonders of the Modern World. It is currently undergoing a $500 million renovation, including $100 million to go "green".

Anthony Malkin, president of W&M Properties, which owns the building, said the technology was devised as a model to retrofit other buildings.
