10 Million Square Feet of SL Green Properties Earn Energy Star

January 25, 2013 By Linda Hardesty

Fifteen buildings in SL Green Realty’s New York portfolio are recipients of the US Environmental Protection Agency’s Energy Star Label.

Among the New York City properties are: 100 Park Avenue, 420 Lexington Avenue, 100 Church Street, 180 Maiden Lane, 521 Fifth Avenue, 673 First Avenue, 600 Lexington Avenue.

In addition, eight buildings in SL Green’s suburban New York portfolio, namely 360 Hamilton Avenue, 140 Grand Street, 150 Grand Street, 100 Summit Lake Drive, 500 Summit Lake Drive, 500 West Putnam, 750 Washington Boulevard and 1055 Washington Boulevard, boast the Energy Star Label distinction.

According to the EPA, properties with the Energy Star Label are more than 30 percent more efficient than those without, resulting in lower operating costs for both the landlord and tenants. SL Green attributes the continued growth of its properties receiving the Energy Star label to the success of its energy efficiency program, efforts of its operations team, and sustainable commitments by its tenants.

Owners of large buildings in New York City must file mandatory benchmarking reports in compliance with the Greener, Greater Buildings Plan (GGBP), which targets energy efficiency in these large existing buildings.

Jay Black, director of sustainability with SL Green, said the requirement has not been the main driver for the company. “We’ve been benchmarking for a while. I will say the local law has helped bring it much more to the forefront.”

SL Green has been benchmarking across its entire portfolio, including areas outside of Manhattan, using software from IES. The IES data is then uploaded to Energy Star’s Portfolio Manager to ascertain the Energy Star score for each building.

“There are a lot of factors that create the Energy Star score,” said Black. “Now that we have these numbers in place, we can see trends over time.”

New York City’s first Energy Benchmarking Report found some anomalies where newer buildings scored lower than some old buildings, and the city is assessing the factors that caused surprising results.
