The Personnel Associated with Significant Energy Uses (SEUs) resource is available within the U.S. Department of Energy’s 50001 Ready Navigator tool. It provides guidance on identifying personnel responsible for areas of major consumption and opportunity for improvement. Identifying key personnel associated with SEUs is one way to greatly impact energy efficiency. This resource outlines the significant energy used, person(s) responsible and energy related actions to take specific to an SEU. Program administrators could use this resource in waste reduction and energy savings opportunity workshops or employee engagement activity, or to determine how people are using SEUs. This tool also helps customers project future energy consumption of each SEU and develop a plan for regularly updating the SEUs.
