NREL Validates Low-Cost Circuit-Level Submetering for Federal Facilities
This case study, prepared for the U.S. General Services Administration by the National Renewable Energy Laboratory (NREL), presents a field evaluation of a low-cost circuit-level electrical submetering system.
Key Findings
The study evaluates wireless, self-powered sensor technology for its accuracy, reliability, and cost-effectiveness in federal facility applications. The evaluation assessed the system's ability to provide granular energy consumption data at the circuit level, enabling facility managers to identify waste, optimize operations, and verify energy savings from efficiency measures.
The findings support the business case for deploying low-cost submetering solutions in federal and commercial buildings as a practical approach to achieving energy management goals and meeting federal energy reduction mandates.
