Duke Energy Center
With a major, mid-project shift, WB Moore still delivered an international headquarters that is quieter than the average public library.
The Duke Energy Center didn’t start out as the Duke Energy Center. When WB Moore began the project, it was called Four Wachovia Place, what would have been the largest uptown facility for the Top 10 financial institution then based in Charlotte, North Carolina.
Before completion, tenant rights to the building were transferred to Duke Energy, requiring major, mid-project changes.
Since the finished project was to be LEED-Certified, extra care had to be given to several areas, not the least of which was to keep the noise generated by the building to under 65db, about the noise level you’ll find in the inside of a public library. (Did you know buildings make noise?)
On the surface, that may not sound like a huge challenge but when you consider that WB Moore had to install six 2,250kW generators producing over 18,000 combined horsepower in the facility and, that residential property is directly across the street, the challenge becomes evident. To accomplish such a low target sound level, these generators were fitted with three silencers each – with only one similar installation of its kind in the world!
unique challenges overcome:
Mandatory 65db at the property line (less than a ringing telephone, a violin five feet away, or the ambient noise in a library)
Multiple generators with thousands of horsepower in code compliance despite being directly adjacent to residential properties
Largest United States installation of the GE Intellisys system at the time.
The proof? An international headquarters for a company responsible for delivering electricity to more than 4 million households.
