Xero Flor America (XFA), the official distributor in the U.S. for the Xero Flor Green Roof System, announced that the system has been installed on the Empire State Building, the World’s Most Famous Office Building. The Xero Flor system was selected for four green roofs: 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.
“With its comprehensive energy-efficiency retrofit program, the Empire State Building has attracted new tenants who derive direct economic benefits from our energy efficiency program and who recognize the value of healthy workplace environments for attracting and retaining talented employees,” says Tom Durels, executive vice president of Malkin Holdings LLC, which supervises the Empire State Building. “The new green roofs further demonstrate our sustainability leadership and add appealing green space that enhances the value of office space for our tenants.”
“Xero Flor is a well-engineered system with the strength and durability required for the challenging conditions on the Empire State Building,” says Rainer Gerbatsch, RRC, LEED AP, president, Commercial Roofing Solutions Inc., Clifton, N.J., roofing and waterproofing consultant for the project. “Xero Flor has a long-standing record of reliability, and we have had success with the system in other projects, most notably on the Javits Convention Center.”
“With the completion of the green roofs on the Empire State Building and Javits Center, 85 Xero Flor green roofs will cover approximately 530,000 square feet of rooftops across New York City,” adds Clayton Rugh, Ph.D., general manager and technical director, XFA. “The green roofs decrease storm-water run-off and improve water quality in New York’s waterways, moderate the urban heat island effect, filter dust and other air pollutants, and store carbon dioxide and other forms of carbon to reduce greenhouse gases.”
