WASHINGTON, DC-The Sierra Club has signed a new lease for 27,238 square feet at 50 F St., NW, where it will build out new LEED certified offices, boosting its own efficiency and demonstrating its commitment to its broad energy efficiency initiatives.

Newmark Knight Frank managing principals Bill Zonghetti and Larry Bank represented Sierra Club in identifying the new location after residing at 408 C St. since its purchase of the property in the mid-1980s. The 216,000-square-foot, class A building is owned by Normandy Real Estate, which was represented by CB Richard Ellis. Sierra Club will be consolidating its offices from 408 C St. and 555 11th St. into the 50 F street location this year.

“We are fortunate to have experienced significant growth over the years and are so happy to be able to house all our employees in one space,” says Sierra Club executive director Michael Brune. “We look forward to occupying our new green space at 50 F, which is conveniently located near Capitol Hill as well as the transportation hubs of the city.”
