Using Metered Data for Energy and Water Evaluations

Abstract

Federal agencies are required by law to install energy meters and conduct energy and water evaluations at their facilities. Per Section 103 of the Energy Policy Act of 2005, agencies are required to collect at least hourly energy data, incorporate metered energy data into data management systems, and provide the data to energy managers. Comprehensive energy and water evaluations of federal facilities are required by Section 432 of the Energy Independence and Security Act of 2007, which states that "covered facilities" which constitute at least 75 percent of facility energy use at each agency must be evaluated every 4 years for cost-effective energy and water savings opportunities. Energy and water metered data can help energy managers make informed operations and investment decisions throughout the energy and water evaluation process. Metered data can be used to identify the facilities with the highest energy use, benchmark facility performance, track facility energy and water use, set energy and water use goals, and prioritize facility investments.
