Installation Energy Successes

These installations are just a few of the many that are going above and beyond to prioritize energy. Learn from these Installation Energy Managers (IEM) and Installation leaders on how energy conservation is done.

Federal Energy Management Program Award Winner

All Installations, and the region as a whole, greatly exceeded the Energy Independence and Security Act (EISA) 2007 goal of a 30% reduction in energy intensity by 2015 and are ahead of their water intensity reduction goals.  The region totaled a 39% reduction in energy intensity from the 2003 baseline and 47% water intensity reduction from the 2007 baseline. A few notable projects include:

  • Energy conservation competitions between commands and similar buildings brought awareness and motivated tenants to reduce their consumption
  • Replacing compressed air agitators with mechanical systems, insulating welding rod storage, installing cooling water controls for rectifier power supplies, and implementing freeze protection control devices and exterior LED lighting
  • Consolidating personnel into fewer bachelor quarters so some buildings can be secured until ships return
  • Installing new software that points out potential HVAC issues in connected buildings
  • Nearly $15M in projects completed during FY 15 (from various years)

Naval Base Ventura County, California (NBVC)

Federal Energy Management Program Award Winner

NBVC saved a total of $457,000 in fiscal year (FY) 2014 from the prior FY, totaling 9,236 MBTU in energy savings, or a 2.7% reduction in consumption due to several project initiatives.

  • The Triton Unmanned Aircraft Systems Training Command required a facility that could accommodate its operational demands and mission.  The successful completion of the major renovation project resulted in 279,740 MBTU savings with cost avoidance of $11,000 annually.
  • Construction of the Fleet Readiness Center (FRC) Aircraft Engine Test Facility: brand new test facility that incorporates efficient features with the lowest practical lifecycle cost solutions saving an estimated 44,783 MBTU per year realizing cost avoidance of $2,000 dollars annually.
  • Lighting upgrades have continued to be a low cost, fast payback effort to improve efficiency and reduce overall consumption. During this period, LED investments in 17 buildings cost $619,934, with rebate savings of $110,000, and energy savings of 3,586 MBTU per year realizing cost avoidance of $136,688.The simple payback was 4.5 years.

 

Naval Base San Diego (NBSD)

Energy Audits and Daylighting

By simply collecting data from a Navy Exchange building, and then showing it to the management, lighting and equipment operating times were modified. A review of time of use energy load profiles led to a shift in start time for lighting and air handlers. As a result of these changes, the Navy Exchange used roughly 500 kilo-watt hours per day less, or 180,000 kilo-watt hours (less) for the entire year.  This resulted in roughly $20,000 in annual savings.

NBSD also completed an energy analysis of the Fleet and Family Support Center (FFSC) complex consolidation project and determined that demolishing five WWII structures and constructing a 57K SF facility would reduce net energy consumption through intelligent site planning, variable air volume HVAC systems, and photovoltaic panels.

Process Modification or Improvement

NBSD developed a pilot computer energy reduction initiative with Navy Marine Corps Intranet (NMCI) to shut down computers remotely during non-duty hours. A 65% reduction in utility usage ($49) per computer was realized. Once fully implemented, annual savings are expected to be over $402K. Annual Regional savings are anticipated to be greater than $1M.

    
Naval Support Activity (NSA) Mid-South

Night Audits of Base Buildings

NSA Mid-South identified a number of appliances and pieces of equipment that were left on at night including TV’s, fish tanks, and space heaters. After elimination of these un-authorized plug loads, a 10% reduction of consumption was achieved.  This resulted in $100,000 in savings for the base over the fiscal year.

    
Naval Air Station (NAS) Whidbey Island

Tenant Energy Efficiency Competition Winner

The Naval Ocean Processing Facility (NOPF) reduced its energy consumption by 121,000 kilowatt hours, a 12% reduction over last year and water consumption by 107,000 gallons, a 21% savings. Their efforts included matching heating and cooling loads to building needs, increased use of outside air cooling water systems instead of mechanical compressors; repairs to Turbo-Core chilled water systems, repairs to building heat recovery systems, installation of new LED lighting, reduction of transformer loads, and more efficient water filtering systems.

   
Naval Air Station (NAS) Lemoore

https://www.cnic.navy.mil/regions/cnrsw/installations/nas_lemoore.html

NAS Lemoore has been striving to improve energy security by transforming the way they use water and by reducing their reliance on fossil fuels. They are actively developing and participating in energy and environmental initiatives to increase the use of alternative energy. Over the past 25 years, they have reduced their water requirements by 43 percent through alternative crops and land uses. They have also installed reduced-flow faucets and showerheads and upgraded the installation’s gym toilets and urinals. With these changes alone, there is an estimated water savings of 20-25 million gallons per year.

   
Portsmouth Naval Shipyard

Energy Efficient Upgrades to Historic Building

This project incorporated several renewable energy technologies such as a solar wall that preheats air by solar radiation, fans that feed the preheated air into the building, and hot water coils that supplement the solar heat. The building's automated heating system manages the operation of the fans so they only run when it is efficient to do so. A new lighting management system also adjusts interior lighting accordingly to maximize natural daylight use from the new window wall.

     
Naval Air Weapons Station (NAWS) China Lake

World-Class Power Generating project

NAWS China Lake has hosted the Coso Geothermal Field for the past 15 years. It is located on their test and evaluation ranges, which is the Navy’s premier research and development facility for air-to-air and air-to-ground ordnance. At its peak, the project produced more than 270 megawatts (MW) of electricity.

  
Joint Base Pearl Harbor-Hickam

http://www.cnic.navy.mil/regions/cnrh/installations/jb_pearl_harbor_hickam.html

Ford Island’s rooftop photovoltaic (PV) array is made up of 1,545 solar panels, designed to provide both power for the facility and added insulation and protection for the roof. It is estimated that over the 30-year lifetime of the photovoltaic system, the solar generated electricity will reduce carbon dioxide emissions by 4,600 tons. This reduction will be equivalent to planting 1,300 acres of trees, removing 1,000 cars, or not driving 11.5 million miles on the island of Oahu.
