The Upper Saucon Township maker of dimmers has been charged with installing technology such as vacancy sensors that turn lights off when a space is unoccupied and daylight dimming controls that adjust light levels based on daylight in the tenant space of the 1,454-foot-tall skyscraper, officials said.
The changes are expected to provide total lighting energy savings of up to 65 percent, Lutron said.
Lutron's efforts are part of an ongoing program to reduce the Empire State Building's energy use by 38 percent and energy bill by $4.4 million a year, preventing 105,000 metric tons of greenhouse gas emissions over the next 15 years, officials said.
Melissa Andresko, a Lutron spokeswoman, said the company has been involved in other projects in the Empire State Building, including installation of its products in the building's main lobby, management office and the 80th floor exhibit.
Lutron has also installed dimmers and shades to lower the electric consumption by two-thirds at the 52-story New York Times building in Manhattan.
