SL Green Realty Corp. is expanding its LED lighting retrofit program, installing more than 8,000 LED lamps across nine Manhattan commercial office properties. The project is projected to save $370,000 annually in operating expenses, according to the Jay Black, SL Green director of sustainability.
The buildings receiving lighting upgrades are: 1350 Avenue of the Americas, 100 Park Avenue, 810 7th Avenue, 461 5th Avenue, 220 East 42nd Street, 100 Church Street, 180 Maiden Lane, 120 West 45th Street and 555 West 57th Street.
“SL Green is excited to continue its third consecutive year installing cutting edge LED lighting technology, contributing toward best-in-class work environments for our tenants,” said Black. “This program will address 24/7 lighting within common areas including lobby, stairs, basement, and mechanical areas to yield significant cost savings, and quick paybacks in less than three years.”
In 2012 and 2013, the company completed the first two phases, establishing one of the nation’s largest LED portfolio lighting retrofits totaling twenty-four commercial office properties, comprising more than fourteen million square feet. More than 24,000 units were installed, replacing antiquated lighting technologies including incandescent, halogen and fluorescent lamps in order to save approximately $950,000 annually.
This next phase, to be completed in August 2014, will retrofit 6.2 million square feet of commercial office space, providing superior efficiency while significantly improving lamp life, often greater than eight years, which is three to four times longer than other lighting technologies. SL Green’s success is already evident, having achieved a fixture failure rate of less than 0.3% of the LED lamps installed.
“SL Green has selected LED products that achieve the greatest efficiency, payback, warranty, access to incentives and quality customer service to significantly impact 90% of lighting lifecycle costs: energy,” said Black, who added the ongoing success of this program continues to strengthen the foundation for future efficiency projects throughout SL Green’s Class A commercial office portfolio.
