The Empire State Building, an architectural icon in New York City and beyond, just took a giant step forward in its quest to reduce energy consumption. The ‘World’s Most Famous Office Building’ now boasts four green roof systems, totally nearly 10,000 square feet.
For its green roof upgrade, the Empire State Building chose to install the Xero Flor Green Roof System for four rooftop areas: 21st floor east (3,450 square feet), 21st floor west (3,450 square feet), 25th floor northwest (1,000 square feet) and 30th floor west (1,200 square feet). The green roofs on the 21st floor feature rooftop patios with outdoor furniture for the enjoyment of office tenants.
As we’ve reported in the past, the Empire State Building is on a quest to become the most sustainable office building in America. In 2011, the building’s owners announced that they would purchase 100 percent of its power from renewable sources and then embarked on a massive retrofit plan that would earn the Empire State Building LEED Gold.
