Point Loma Naval Base

When the Point Loma Naval Base energy team discovered there might be a way to reduce the energy wasted by the cooling systems in their buildings, they jumped at the chance to use the new technology.

The team chose Building 56, a 165,000 sq. ft. space, as the test building for the new LOBOS system. Along with LOBOS, they installed a new variable speed chiller and a “variable everything” chilled water pumping system.

Installing the new system has considerably reduced energy consumption and related costs, saving approximately 1.25 million kWh and $231,000 annually. Overall plant operation has also been reduced by over 1,500 hours per year, due to LOBOS “Thermal Flywheel” logic, which shuts down chillers and uses the cold water still in the pipes to meet small loads.

Efficiency has also increased; the new system is running around 0.52 kWh per ton. In its first year of installation, the system ran at an efficiency savings rate of 70% higher than before the upgrade. In subsequent years, due to plant and equipment changes, the new system has delivered a consistent energy efficiency savings rate of 58%. In addition, the LOBOS system effectively cools the building without wasting energy, creating a comfortable environment for workers.

LOBOS savings rates at Building 56 have resulted in several more ongoing projects at the Point Loma Naval Base.
