SL Green Realty Corp., New York City's largest commercial property owner, has selected Seesmart Technologies’ LED lighting products to replace antiquated lightings throughout 21 commercial office properties, as part of one of the nation's largest LED lighting efficiency projects.

There are more than 16,000 Seesmart LED lamps to replace antiquated lighting technologies, including incandescent, halogen and fluorescent lights, to provide exceptional efficiency that reduces energy use by more than 50 percent. This is combined with superior lamp life of more than 8 years, which yields additional savings opportunities.

SL Green anticipates this energy efficiency project will save $750,000 through combined energy and material/labor savings, resulting in a project payback of only 3 years.

"SL Green is excited to commence with this innovative project, utilizing Seesmart LED products, to drive energy reduction throughout our portfolio," said Jay Black, Director of Sustainability at SL Green. "Lighting represents approximately 25 to 30 percent of total energy cost in the commercial real estate industry, and addressing lighting efficiency is a key 'low hanging fruit' cost savings opportunity. SL Green found that Seesmart provides the incomparable solutions necessary, including high quality products, superior efficiency, longevity, warranty and exceptional customer service required to pursue this efficiency program."

SL Green anticipates the completion of the LED lighting retrofit in August 2012. This program is expected to be a catalyst for future retrofit opportunities, including mechanical, renewable energy, and additional LED lighting retrofits at other properties within its portfolio.
