Kuwait Energy Efficiency Project

Performance Work Statement (PWS)

25 October 2012

1.0 Scope

This PWS describes the requirement for the Kuwait Energy Efficiency Project (KEEP).

The primary purpose of the KEEP is to improve energy efficiency within Area Support Group - Kuwait (ASG-KU), Camp Buehring. Specifically, the Army desires to leverage mature, low risk technologies to reduce the energy load and provide supplemental renewable energy sources within selected Camp Buehring billeting areas while at the same time improving the living conditions of service members currently living in tents.

This requirement is intended to reduce energy consumption and improve quality of life by replacing poorly insulated soft walled tents with modular rigid walled energy efficient shelters. Energy efficient shelters will be integrated with efficient Environmental Control Units (ECUs), Light Emitting Diode (LED) based lighting and photovoltaic arrays to supplement power during peak daytime load periods.

1.1 Background

Energy is a critical resource that must be readily available to support Army missions at fixed installations and Forward Operating Bases. The Army Energy Security Implementation Strategy dated January 13th, 2009 details the Army’s vision and goals relative to the Department’s desired energy posture. These goals include reducing energy consumption, increasing efficiency, increasing use of renewable/alternative energy sources, and assuring access to energy supplies. In-line with these goals and recent Combatant Commander operational energy requirements, LIA in partnership with ASG-KU seeks to rapidly introduce capabilities that can improve the overall operational energy posture within Camp Buehring.

Currently, Camp Buehring provides billeting for military units using soft walled tents that have little insulation, are heated and cooled by inefficient and oversized ECUs, and use standard fluorescent lighting (interior) and halogen (exterior) area lighting powered by a hydrocarbon driven electrical system. The combination of these factors leads to high energy use within base camps and a significant logistics burden. Single wall tents have thermal resistance (R values) between R-1 (temper tents) to R-5 (American Tents).

This means they have very little insulation qualities. Consequently maintaining cool temperatures inside of tents within Kuwait during the summer requires a constant high volume flow of refrigerated air.

1.2 Objective

The objective of this effort is to combine existing commercial-off-the-shelf technologies into an integrated solution for shelter efficiency and supplemental power generation.

The replacement of soft walled shelters with highly insulated rigid walled shelters that are soldier erectable, re-deployable, equipped with energy efficient ECUs, and LED lighting will greatly improve energy efficiency. This work is expected to produce many benefits, including but not limited to:

Improved efficiency

Substantial reductions in fuel/energy consumption

Reduction in fuel transportation frequency

Reduction of operation and maintenance costs

Reduction of Capital Investment for Lease/Purchase of generators

Integration of renewable power sources

Increased operational flexibility

Improved quality of life using quieter, less permeable structures

Improved environmental sustainability

An opportunity for the Army to collect before and after load profile data to help inform future planning and decision making.
