Cushman & Wakefield’s Asset Services and Sustainability Services divisions collaborated to achieve a LEED® Gold certification for Heron Tower, an asset owned by client Takenaka International. This is the first U.S. LEED project to acquire certification undertaken by Takenaka.
“Takenaka’s target at Heron Tower was LEED Silver, and we are beyond pleased to have exceeded the expectation,” said Joseph McCausland, property manager. “The building team worked hard to find sustainability savings and areas of improvement, and our vendors and general contractors demonstrated their ability to meet the strict requirements set forth by the U.S. Green Building Council.”
Built in 1987, Heron Tower is a 154,000-square-foot office building located in the Plaza District of New York City. Cushman & Wakefield has managed Heron Tower since 1991.
Takenaka International wanted Heron Tower to become the first building in their portfolio to pursue and achieve a LEED designation, specifically targeting LEED Silver.
Over a two-year period beginning in 2016, the following building improvements were made with strict adherence to Cushman & Wakefield’s sustainability policies:
