Saving energy requires an initial investment, but the savings mount quickly.
A study by the Rocky Mountain Institute and the U.S. General Services Administration (PDF) entitled Deep Energy Retrofits Using Energy Savings Performance Contracts: Success Stories outlines how the U.S. Navy plans to save $6.07 million annually. Through a 15-year retrofit scheduled for completion in 2017, Naval Air Station (NAS) Oceana in Virginia Beach, Va., is expected to see its 110 builds spread across 5.38 million square feet have their energy consumption reduced by 40 percent.
The $89.6 million project includes upgrades like steam and chiller plant decentralization, energy-efficient HVAC equipment, renewable energy sources that include solar, thermal ground-sourced heat pumps, digital controls that measure more than 18,000 facility metrics, lighting retrofits of more than 40,000 fixtures, and water retrofits of more than 10,000 fixtures.
The project is centered around the base’s outdated steam plant, which was decommissioned after it became too corroded to repair. The four-phase project has been recognized for its success thus far, receiving the 2011 VSBN Green Innovation Award, the 2009 Presidential Award for Leadership in Federal Energy Management, and the 2009 Platts Green Energy Initiative of the Year award.
