Retrofitting the World's Most Iconic Office Building


The Empire State Building announced today that its energy efficiency program is saving $2.3 million for the second year in a row – beyond expectations.    Thanks to the program, the building has been saving money on energy costs since 2011. In addition, the building – which set records in 1931 when it was built as the tallest building in the world and is the world’s most famous office building – is proving that even historic, commercial buildings ­can become energy-efficient and economically sustainable.  

The Empire State Building’s energy-efficiency retrofit program launched in 2009 and was developed by the Clinton Climate Initiative in partnership with the C40 Cities Climate Leadership Group, Johnson Controls, Jones Lang LaSalle, Rocky Mountain Institute, and the Empire State Building. While the core of the building’s retrofit has been completed, some tenant spaces are still being retrofitted with high-performance workspaces. When they’re done, the building is expected to save $4.4 million a year on energy costs, which is a 38 percent reduction in energy use that will also mean a reduction carbon emissions by 105,000 metric tons over the next 15 years.

What’s more, this retrofit model has been replicated throughout the United States at properties including the One Worldwide Plaza in New York, the Port Authority of New York and New Jersey, the Port of San Francisco’s Pier 1, Prologis Inc.’s corporate headquarters, the Moscone Center in San Francisco and Chicago’s Union Station, among others. From coast to coast, the program continues to show that even in dense urban centers like New York and San Francisco, where commercial buildings account for up to 75 percent of energy used, sustainable solutions exist that are also cost-effective. In fact, if every commercial building in New York City replicated this program model, carbon emissions would be reduced by 4 million tons. The record-setting building has become a trendsetter!
