111 South Wacker Drive in Chicago receives second LEED Gold certification

The spectacular 52-storey landmark building 111 South Wacker Drive in downtown Chicago is the world’s first-ever speculatively built high-rise office building to be certified LEED-CS (Core and Shell) Gold for its sustainable construction. 111 South Wacker has now also become one of the first office buildings to receive LEED-EB (Existing Building) Gold certification, which is awarded by the U.S. Green Building Council in recognition of an existing property’s sustainable operation. Developed by the John Buck Company, the office tower was acquired by Union Investment in 2005 for its open-ended real estate fund UniImmo: Europa. It offers some 96,000 square metres of office space, which is fully let.


“This rare double certification underlines the extremely high quality of the building, which pays off for users and for us as investors through stable cashflows and value appreciation,” says Dr. Karl-Joseph Hermanns-Engel, member of the management board of Union Investment Real Estate GmbH. Union Investment currently holds 15 properties and projects in its open-ended real estate funds that are certified according to LEED, BREEAM, DGNB or other established systems for their sustainable construction.
