The Department of Energy's (DOE) Federal Energy Management Program (FEMP) requested an update of the original market assessment done by Pacific Northwest National Laboratory (PNNL) in 2001. This original analysis evaluated water conservation opportunities and answered key questions necessary for FEMP to make recommendations on whether or not to proceed with strategies for water conservation in the Federal sector, primarily through the development of water conservation Energy Savings Performance Contracts (ESPC). The update's intent is to reevaluate the cost-effective water savings potential in the Federal sector, which incorporates new technologies and recent available data on Federal water use, and also to make recommendations on strategies that will assist FEMP in developing a path forward to assist Federal agencies in effective water management. This updated assessment is based on a new analytical approach that utilizes newly available data and technologies. The new approach fine-tunes the original assessment by using actual Federal water use, which is now tracked by DOE (as compared to using estimated water use). Federal building inventory data is also used to disseminate water use by end-use technology in the Federal sector. In addition, this analysis also examines the current issues and obstacles that face performance contracting of water efficiency projects at Federal sites. A summary table of the cost-effective savings potential results of this updated evaluation is provided in this paper, along with bulleted points of key findings and recommendations of the update. Includes table.
