PORT HUENEME, Calif. (NNS) -- Two Naval Facilities Engineering and Expeditionary Warfare Center (NAVFAC EXWC) engineers received the Society of American Military Engineers (SAME) project of the year award at a ceremony in Oxnard, Calif., Feb. 20.

David Chavez and Bruce Holden were recognized for their work on Energy and Environmental Sustainability at Camp Lemonnier, Djibouti.

"David and Bruce developed and led several teams to support Camp Lemonnier in reducing energy need in containerized living units (CLUs)," said NAVFAC EXWC Commanding Officer Capt. Mark. K. Edelson. "Their work in improving energy usage is invaluable and has direct benefits to our warfighters in Djibouti and in locations around the world."

The energy improvements were largely based on modified environmental control units within existing CLUs (also referred to as "Super CLUs"); power grid revisions; reducing water needs through improved facilities and increased re-use water; and the reduction of solid waste burned in the camp incinerator.

"I was happy to accept this award as part of a great EXWC team effort," said Chavez, EXWC environmental engineer. "Multiple departments were used to provide excellent support to Camp Lemonnier to reduce energy use, reduce water consumption, and reduce solid waste."

The Super CLUs save thousands in energy usage, increase living space and privacy for individuals, reduce noise and allow more personnel to be comfortably housed in a given unit than current CLU configurations.

The project also reduced fuel burned in camp generators by 500,000 gallons while increasing total energy output by 2 million kWh. Water use was also reduced by 50,000 gallons per day through the use of low water use washing machines and low flow shower heads.

The team's successful demonstration of variable, split load HVAC (Heating, Ventilation and Air Conditioning) units led the camp to purchase and replace all CLUs and environmental control units (ECUs), with 900 of 1500 units replaced and the remainder changed out by the end of FY14.

The improvements are being adapted across NAVFAC, with one facilities engineering command incorporating EXWC ECU recommendations into future CLU purchases.

NAVFAC EXWC is the Navy's premier activity for facilities and expeditionary technology solutions, engineering services, equipment logistics and products needed to equip the fleet and meet warfighter requirements. EXWC also delivers specialized engineering and technology solutions that support sustainable facilities and provides logistics and expeditionary systems support for Navy combat force capabilities.
