The Duke Energy Center (A Wells Fargo Bank Property) officially received its LEED Platinum certification, recognizing it as the most sustainable skyscraper in America.
Only the Duke Energy Center in Charlotte and Bank of America’s One Bryant Park tower in New York have achieved the highest green-building rating from the U.S. Green Building Council. And the Charlotte building grades out just a bit higher on the scorecard, making it the unofficial No. 1.
Wachovia started building the 1.4 million-square-feet, 48-floor tower five years ago. It was intended to be the bank’s headquarters. But after acquiring Wachovia in 2008, Wells Fargo sold the naming rights to Duke Energy. Still, the new ownership completed the building and will continue to own the impressive structure.
Rick Fedrizzi says it has the potential to foster a wave of green building in the Charlotte area. It also forces people that encounter the building to examine their own sustainability efforts. “It’s about changing the way people think. Ultimately, we can transform a generation,” he says. “This is a great story because there’s no way you can look at the Charlotte skyline and not believe this is a wonderful, energized place to live.”
BRAE worked in partnership with Boda Plumbing and Richard Bodenheimer, PE to succcessfully integrate the rainwater and condensate recovery system from conceptual design through implementation. The system consists of multiple cast in place concrete tanks continuously monitored with level controls. The BRAE Rainset control station utilizes a combination of ozone disinfection, UV disinfection and particle filters to provide product water to:
Cooling Tower Makeup
Green Roof Irrigation
