PORTSMOUTH, Va. (NNS) -- High efficiency lighting construction and compressed air repairs are underway as part of an Energy Savings Performance Contract (ESPC) encompassing more than 90 buildings at four Portsmouth, Va. sites in an effort managed by the Naval Facilities Engineering Command Mid-Atlantic.

The contract, awarded in December 2009, will see a total energy savings of 32,802 million British thermal units (MBTU) per year and an estimated annual cost savings of nearly $687,000.

"More than 90 buildings will receive the high efficiency lighting upgrades," said Ensign Andrew Bessette, assistant Public Works officer, PWD Portsmouth. "This energy conservation measure will provide for the replacement, or retrofit, of existing light fixtures with high efficiency lamps, ballasts and reflectors."

Bessette also noted that after overlit areas are de-lamped as needed and occupancy sensor controls are added to minimize lighting use during periods of non-occupancy, the estimated energy savings will be at 14, 634 MBTU per year.

Three buildings will be receiving compressed air repairs and will see an estimated energy savings of 1,740 MBTU per year.

In addition to the high efficiency lighting retrofits and the compressed air repairs now under construction, the scope of work on this contract includes direct digital controls upgrades, to begin June 21, to 14 facilities inclusive of 59 electric meters being installed through the DDC monitoring system to assist in monitoring and billing of utilities to facilities; and 2,200 linear feet of direct buried steam and condensate line replacement at Naval Medical Center Portsmouth, to begin mid-July.

Norfolk Naval Shipyard, along with the Scott Annex and St. Julian's Creek Annex sites will also receive energy saving upgrades.

An ESPC is a contract with an energy services company (ESCO) to implement energy improvements. ESPCs always provide a savings guarantee and often include operation and maintenance of the equipment over the contract term. The ESCO develops and finances the capital cost of the project, installs it and is repaid over the contract term from the energy costs savings.

"Energy Savings Performance Contracts are an extremely powerful tool to obtain energy savings and infrastructure recapitalization with no 'up front' funding. The contract is paid for entirely out of energy savings and no payments are made until the project is constructed and operational, generating energy savings," said Beverly Wade, Navy ESPC project manager.

Wade added that this type of contract allows the Navy to make significant strides in energy conservation, environmental stewardship and sustainability without impacting the current utility budget.

Expected completion date for work on this project is May 2011.
