ARRA Project Goes High Tech to Conserve Energy at Camp Lejeune

CAMP LEJEUNE, N.C. (NNS) -- Photovoltaic (PV) panel installation wrapped up April 29 at one of two buildings at Camp Lejeune receiving the solar panels.

This project will help with energy conservation on the installation.

The buildings, a pair of 1940s era warehouses, are receiving this upgrade with funding from the American Recovery and Reinvestment Act (ARRA).

The officer in charge of Construction Marine Corps Installations East (OICC MCI East) awarded a $3.5 million contract last June to replace mechanical, electrical and roofing systems, at buildings 1316 and 1317 at Camp Lejeune, N.C., to North State Mechanical, Inc., a local small business construction firm from Jacksonville, N.C.

This contract provides for the replacement of existing built up roofs with cool white-reflective, Leadership in Energy and Environmental Design (LEED) certified roofing systems with installed solar panels, and replacement of HVAC, plumbing, water heating and steam/condensate systems with more energy efficient systems.

"This project will provide for increased cooling and heating efficiencies while reducing heat infiltration through the roof along with solar power generation," said Cmdr. Cheryl Hansen, commanding officer, OICC MCI East, Naval Facilities Engineering Command (NAVFAC) Mid-Atlantic. "Because of this ARRA project, the Marines will receive the benefits of better interior temperature control and quality of life at a lower cost."

A cool roof is one that reflects more and absorbs less of the sun's radiant energy while emitting its absorbed (non-reflected) energy more quickly. LEED is a building rating system that is used as a guide in environmental design. It uses a point system to establish an overall building performance rating. Cool roofing technology greatly reduces heat transfer to a building's interior and can result in savings of 20 to 30 percent in annual cooling energy consumption.

PV solar panels have embedded semi-conductor cells that transform the sun's radiant energy into electrical power. This power offsets electrical demand to the local utility at a substantial savings. PV technology is gaining much popularity as an alternative energy source because it is simple in concept and the basic materials are abundant and inexpensive.

PV panel installation at building 1316 has just finished. Building 1317 will receive PV panels after its roof replacement phase. Other mechanical and electrical work is ongoing in both facilities. Construction is approximately 35 percent completed and the entire project is scheduled to be finished by June 21.

NAVFAC manages the planning, design, construction, contingency engineering, real estate, environmental, and public works support for U.S. Navy shore facilities around the world. It provides the Navy's forces with the operating, expeditionary, support and training bases they need. NAVFAC is a global organization with an annual volume of business in excess of $18 billion. As a major Navy Systems Command and an integral member of the Navy and Marine Corps team, NAVFAC delivers timely and effective facilities engineering solutions worldwide.
