Millions of people pass through the doors of Manhattan’s glassy Jacob Javits Center each year, but most have no idea what lies right above their heads. While it might not be obvious from below, the sprawling convention center is home to the second largest green roof on a single, free-standing building in the United States. Durham-based company Xero Flor was responsible for transforming 292,000 square feet of the urban rooftop into an energy-saving green haven using sedum grown on a farm in Upstate New York.

Xero Flor’s green roofs support local and independent farmers all over the country, and grow their grassy greenery to maturity for 9 to 12 months before installing them on clients’ rooftops. Founded by Dr. Clayton Rugh, Xero Flor is a multi-layer system that combines sod, dirt, seed and fertilizer with energy-saving technology.

In addition to looking pretty, the green roof system saves the Javits Center heaps in energy costs each year. Since the sod system acts like a giant sponge, it absorbs and diverts a whopping 6.8 million gallons of water per year, helping to prevent flooding along the West Side.  The green roof also insulates the massive convention center, keeping heat out in the summer and cold out in the winter.

Aside from all the climate control and energy benefits, the planted surface also helps the roof of the Javits Center last much longer, safeguarding it from weather-related wear and tear – and also serve as inspiration for other buildings in Manhattan!
