SEAL BEACH, Calif. (NNS) -- Paving the way for greater energy efficiency, Naval Weapons Station Seal Beach announced the completion of comprehensive energy audits for its Seal Beach, Detachment Corona and Detachment Fallbrook installations, Oct 3.

"The audits take a detailed look at everything that impacts energy and water consumption including motors, lighting, boilers, air conditioning, and building envelope," said resource efficiency manager Matt Duke. "The requirement is to do a comprehensive energy and water audit of the top 75 percent of energy consuming facilities on a four-year cycle."

The reports included assessments on existing building and equipment conditions as well as specific energy conservation measures supported by an economic analysis.

As the Navy heads into the future, energy and resource conservation are increasingly important factors in creating energy security for the Navy. These ideas are laid out in the Energy Independence and Security Act of 2007, said Duke.

"The audits are intended to assist with meeting the Navy's aggressive energy reduction and alternative energy objectives," stated Public Works Officer Lt. Cmdr. Chad Lorenzana. "These reports examine how Seal Beach and detachment facilities are performing from an energy standpoint and present opportunities for future energy projects."

Existing conditions revealed during the Seal Beach audit include several buildings found utilizing old manual controls or pneumatic controls. According to the report, these types of systems are inefficient, and do not have the capacity for occupancy controls which allow for heating and cooling systems to stop when the building is unoccupied.

Seal Beach's report also includes water conservation opportunities which were found during the survey walkthrough. Such improvements would include typical domestic plumbing enhancements such as low-flow restroom retrofits and shower-head replacements.

During Detachment Corona's audit, the report revealed that the installation's primary tenant, Naval Surface Warfare Center (NSWC) Corona Division, should look into installing building automation. Along with energy savings, significant labor savings could also be achieved, the report noted.

The audit for Detachment Fallbrook includes recommendations for expansion of Direct Digital Controls (DDC) for air conditioning systems.

"Energy efficient programming strategies would be included into all phases of this DDC energy conservation measure, including start/stop or run time optimization and unoccupied temperature controls," said Duke.

"All of the findings during the audit will contribute to the Navy's overall goal of maintaining energy efficient facilities to better save and reduce unnecessary usage, both domestically and worldwide," said Lorenzana.

In August, the Navy announced that the Seal Beach command had won a 2011 Secretary of the Navy Energy and Water Award, Platinum level of Achievement, while NSWC Corona Division picked up a Gold Level of Achievement award.

Secretary of the Navy Ray Mabus laid out five aggressive energy goals in October 2009 to improve energy security and efficiency, increase energy independence, and help lead the nation toward a clean energy economy. This initiative assists in achieving the energy goal of increasing alternative energy afloat and ashore where by 2020, the Department of the Navy (DON) will produce at least 50 percent of shore-based energy requirements from alternative sources and 50 percent of DON installations will be net-zero.
