Duke Energy Center has been certified at the highest level of environmental certification by the U.S. Green Building Council.
The 48-story building, which opened in January, is the first and
tallest office tower to receive the certification.
The building initially was meant to be the new headquarters for
Wachovia Corp. But after Wells Fargo bought the collapsing Wachovia in
late 2008, Duke Energy Corp. took over the naming rights to the tower.
Among the center's green attributes are recycling rainwater, and a
roof that reduces heating and cooling costs. The Duke Energy Center is located in Charlotte, North Carolina.
