Fort Hunter Liggett & Park Reserve Training Force

Work Performed

Fort Hunter Liggett provides world class training for combat support and combat service support units of the Army Reserve, as well as offers top training opportunities to all US military components and allied nations. The base has achieved top honors for their Net Zero site efforts and is now focused on optimizing their buildings’ efficiency.

Fort Hunter Liggett, in conjunction with Pacific Gas & Electric, partnered with Southland Energy to develop and implement a $4.8 million self-funded Utility Energy Service Contract (UESC). The project supported Fort Hunter Liggett’s goal of improving overall efficiency, reducing deferred maintenance, and remaining on track to meet federally mandated energy reduction goals. Southland Energy was selected to identify energy conservation measures and help achieve the base’s goals across 27 buildings. Spanning 645,000 square feet, the design-build energy conservation measures included site-wide exterior LED lighting, high-efficiency HVAC equipment installation, expanding and upgrading energy management controls, and domestic plumbing installation. The exterior lighting measure extended to Parks Reserve Training Force Area (PRFTA) in Dublin, California, which is managed by the Fort Hunter Liggett’s Directorate of Public Works.

Southland’s turnkey services included conducting a detailed feasibility study, design and engineering services, demolition of jet propellant 8 (JP-8) and propane tanks, and installation of HVAC roof top units, ductwork, four 1000-gallon domestic hot water storage tanks, air to water heat pumps, and variable air volume. Southland also expanded and upgraded the facilities’ BACnet compatible Tridium building management systems. The upgrade greatly improved the system’s operational efficiency by enabling the staff to perform controls, energy management, and system diagnostics and troubleshooting.

Overall, the self-funded project significantly reduced deferred maintenance and energy consumption, as well as met Fort Hunter Liggett’s goals to increase energy efficiency, reduce fossil fuel reliance, and improve comfort. Although the project had a tight schedule, Southland’s collaboration with Fort Hunter Liggett and Pacific Gas & Electric led to the project being completed on time and with zero recordable injuries.
