Empire State Building Achieves LEED Gold for Operations

One of the largest energy-saving features of the building-wide project is a retrofit system that preserves the historic glass and window frames from the iconic building’s 6,514 windows, turning them into super-insulated glazing units that include suspended, coated film. “By earning LEED Gold, the Empire State Building has sent a powerful message that green buildings don’t have to be new,” said Rick Fedrizzi, president and CEO of the U.S. Green Building Council, in a press release.

The Empire State Building’s recent LEED Gold designation does not end with deep energyretrofit. It represents an ongoing commitment to energy and water efficiency, indoor environmental quality, waste reduction, and other measures.

The 2.85-million-square-foot building, completed in 1931, is also a National Historic Landmark. The offices of one tenant, Swedish construction company Skanska, earned LEED for Commercial Interiors certification at the Platinum level on the same day.
