Built in 1930–1931, the original construction of the Empire State Building (ESB) in New York, New York, took 1 year and 45 days, the equivalent of 7-million man hours, to complete. When it came time to renovate one of the world’s most famous skyscrapers, Armacell was part of the team. The $20 million renovation to modernize energy conditions, guided by a partnership between the Clinton Climate Initiative (CCI), Johnson Controls Inc. (JCI), Jones Lang LaSalle (JLL), and Rocky Mountain Institute, has delivered a 38% energy savings and earned this historic icon a LEED® Gold certification for Existing Buildings: Operation & Maintenance.
Renovations include everything from triple-glazed windows to occupancy sensors and involved the installation of more than 6,000 insulated reflective barriers behind radiator units located on the perimeter of the building. For the ducts, “AP-Armaflex self-adhering duct liner was written into the Empire State Building’s specifications several years ago—[and was chosen again] without any substitution,” said Bob Dizel, retired Northeast Sales & Market Manager for Armacell. Properly installed, Armaflex should last as long as the duct itself, said Mr. Dizel, adding that it is a solution for insulation, condensate control, and noise attenuation, which is a large job for a 1,250-foot building that has 102 stories and features observatories on the 86th and 102nd floors.

The project has been successful. According to www.esbnyc.com, ESB also received the 2011 Green Power Leadership Award from the U.S. Environmental Protection Agency (EPA), and USGBC monitoring and verification proved ESB’s retrofit project exceeded projected energy savings for the consecutive years and reduced costs by millions of dollars each year.
