MAYPORT, Fla. – Naval Facilities Engineering Command (NAVFAC) Southeast and their
Utilities Energy partner - TECO Energy of Tampa, Fla. completed a $13.4 million Utility
Energy Service Contract (UESC) project at Naval Station (NS) Mayport in Jacksonville,
Florida, October 27. The project will result in approximately $600,000 annually in combined
energy and water savings base-wide.
A UESC is a limited-source contract between a federal agency and its serving utility for
energy- and water-efficiency improvements and demand-reduction services.
“This project brings NS Mayport closer to meeting its Navy shore energy reduction
goal,” said NS Mayport Installation Energy Manager Warren White. “This was a holistic
installation facilities approach; which included all types of facilities, such as, training,
administration, warehousing, single sailor quarters, child care and paid lodging.”
The scope of the project called for the design and installation of interior and exterior lighting
upgrades, water conservation measures, and expansion/upgrades to Mayport’s energy
management and control system (EMCS) and impacted more than 50 facilities aboard the
base. The project also included transformer replacements to improve energy security and
mechanical upgrades to modernize the heating, ventilation and cooling (HVAC) systems in
many of the base facilities. All the EMCS improvements were carefully analyzed for
compatibility with Department of the Navy cybersecurity and ‘Smart Grid’ future goals.
“This was a very difficult construction project to coordinate as work was done in over 50
buildings and impacted every Mayport Command,” said NS Mayport Construction Manager
Bruce Pastorini. “The project was completed safely, on budget and 30 days early.”
The installation of high efficiency lighting upgrades, lighting controls systems upgrades,
HVAC system upgrades and electrical systems upgrades, will allow the installation to
save enough energy to power more than 600 average homes for a year.
“This was not only an energy project, but also an environmental sustainability endeavor
with Florida Fish and Wildlife Conservation Commission and United States Fish and
Wildlife Service, all new exterior lighting will be an amber color meeting the turtle wildlife
lighting requirements and guidelines,” said White.
Many of the electrical savings built into this contract utilize modern as well as emerging
building technologies. Lighting upgrades consisted of converting and retrofitting interior lights
in buildings with light-emitting diode (LED) light sources. The high-efficiency exterior lighting
improvement upgrades were specially choosen to ensure against any conflict endangering
the indigineous turtle habitations found base-wide. The project also brought a host of HVAC
advances to NS Mayport, including the installation of variable frequency drives and variable
volume air handling units. In addition, sub-metering capabilities were added to Mayport’s
existing EMCS system. Sub-metering will allow energy managers and facility managers to
track and monitor real-time energy consumption of different building loads (HVAC, lighting,
office equipment), and provides a clear and accurate picture of how and when energy is
being consumed inside a facility.
“We need to manage energy in the coming years,” said White. “This will be the future home
of six Littoral Combat Ships (LCS) which may bring more Sailors and supporting personnel to
the installation. We’ve focused on the human aspect of energy conservation, lighting, water
and HVAC in this project, to position the installation for continuous energy reduction in the
The project falls under the Energy Independence and Security Act of 2007, which authorizes
agencies to use appropriations, private financing, or a combination of both to comply with its
requirements for Utility Energy Service Contracts (UESC) for evaluations/project
implementation. It also supports former President Barack Obama's announcement,
December 2011, of a $4 billion investment in energy upgrades to combined federal and
private sector buildings. When announced, the investments were intended to save billions in
energy costs, promote energy independence and, according to independent estimates,
create tens of thousands of jobs in the hard-hit construction sector. The $4 billion investment
in 2011 included a $2 billion commitment, made through the issuance of a Presidential
Memorandum, to energy upgrades of federal buildings using long term energy savings to pay
for up-front costs, at no cost to taxpayers.
