JACKSONVILLE, Fla. (NNS) -- Naval Facilities Engineering Command (NAVFAC) Southeast awarded 59 restoration and modernization energy projects totaling $40.9 million in fiscal year 2013.
The projected savings from these projects is expected to be more than 350,000 MBTU, which is a 3.3 percent reduction in energy usage from the 2003 Navy Region Southeast baseline.
A British Thermal Unit (BTU) is defined as the amount of energy needed to cool or heat one pound of water by one degree fahrenheit. An MBTU is one million BTUs and is typically used to measure medium to large scale energy consumption. Cost savings on average per MBTU for these projects is $21.
"The Department of the Navy (DoN) issued a new energy policy (OPNAV Instruction 4100.5E - Shore Energy Management) in June 2012 that is driving energy consumption reduction at all Navy installations, transforming the energy culture and seeking new or existing technical solutions for reducing energy," said NAVFAC Southeast Energy Manager Brad Clark. "The Shore Energy Management instruction is a complete revision from the 1994 version."
The instruction affirms the Navy's policy and strategy to ensure energy security as a strategic imperative. It also directs the Navy to meet or exceed federal mandates and executive orders.
Since naval forces require constant support from ashore installations, the Navy is reducing its vulnerabilities related to electrical grids by lowering consumption, integrating renewable energy sources and increasing control of energy supply and distribution. Energy reliability, resiliency and redundancy are essential components of the Navy's Critical Infrastructure Protection program.
"The instruction further directs the Navy to use the most cost effective means to meet shore energy goals including a 50 percent ashore consumption reduction by 2020, achieving a total ashore energy usage rate of 50 percent from alternative sources by 2020, and reducing the amount of petroleum used in commercial vehicle fleets by 50 percent by 2015 and other goals," explained Clark.
Some of the technology highlights instituted by NAVFAC Southeast bases in fiscal 2013 included the installation of Light Emitting Diode (LED) exterior lighting, solar water heating, high efficiency chillers and motors, Direct Digital Controls, and HVAC optimization improvements.
Naval Air Station (NAS) Jacksonville executed the most energy projects, a total of ten, while NAS Pensacola expects to save the most energy - just under 92,000 MBTU - from executed energy projects.
At NAS Pensacola, a contract for $2.8 million was awarded for upgrades to HVAC systems, lighting replacement, and water consumption upgrades in Buildings 3221, 3460, 3828 and 3465. Projected annual savings are projected to be 16,331 MBTU.
Naval Submarine Base Kings Bay awarded a contract valued at $5 million that will see the replacement of approximately 2,833 lights and fixtures with new LED lighting fixtures and save 7,860 MBTU annually.
Chillers in Buildings 126, 300/300B, 321, 484 and 485 will be modernized at Naval Support Activity Panama City. The award was valued at $1.6 million and will save approximately 4,200 MBTUs annually.
During fiscal year 2014, 10 installations throughout the Southeast are programmed to receive 27 projects totaling $30.3 million. These projects are projected to save 146,000 MBTUs and will put the Navy well on its way to meeting its energy reduction goals. Projects range from exterior lighting replacements to more complex HAVC modernization and controls optimizations.
