SL Green Realty Corp.’s 100 Park Avenue, the 1950s completely redeveloped trophy tower across from Grand Central Terminal, has officially achieved LEED silver certification from the U.S. Green Building Council.

“Since completion of its redevelopment, [100 Park Avenue] has experienced unprecedented success and recognition as a trophy property within the SL Green portfolio,” says Edward Piccinich, executive vice president of SL Green. “There's no doubt that our recent renovation of the property certainly served as a vehicle for renewed interest and public attention.”

The recipient of a comprehensive $72 million capital program, the 36-story, 825,815 sq. ft. tower’s makeover features significant infrastructure upgrades including new a cooling plant, increased electric capacity, and state-of-the-art security systems.

LEED certification is based on the building’s aggressive enhanced recycling capabilities and energy management program, including the installation of low-flow plumbing fixtures that reduce water consumption by an estimated 50% or almost 1 million gallons of water per year.

“The building redevelopment successfully balanced a very attractive aesthetic together with a commitment to environmental sustainability,” says Steve Durels, vice president and director of leasing for SL Green. “Just as important are the real savings that we have achieved through our green initiatives, the operational efficiencies as well as the enhancement to the value of the property.”
