The Corey Center in Atlanta, Georgia is a 35,000 square foot commercial property combining office and warehouse space. With high electrical demand and multiple breaker panels, it was an ideal candidate for energy optimization using Tune®.

Eight Tune® devices were installed—one for each subpanel—and monitored over four years by third-party energy analysis firm Noesis.

1. Verified Long-Term Savings

Unlike a short-term test, this case study covered four separate years of performance data. Noesis compared adjusted baseline energy use to actual usage post-installation and found consistent savings across all years.

2. Results by Year

• Year 1: 6.0% savings

• Year 2: 17.5% savings

• Year 3: 17.9% savings

• Year 4: 18.0% savings

• 4-Year Average Savings: 14.8%

Total reduction: 93,844 kWh saved across all four years.

3. Low Effort, High Return

The Corey Center installation didn’t require operational changes, software, or behavioral training. Once installed, Tune® passively filtered out harmful harmonics from the electrical system—improving efficiency and lowering demand.

Conclusion:

For commercial buildings with complex power demands, Tune® delivers long-term savings without disruption. The Corey Center case proves that even over multiple years, the device keeps doing its job—quietly improving energy performance where it counts.
