Submeters and Analytics: Wireless CTs

Integrated sensors and analytics are simplifying submetering and driving costs down. Wireless CT sensors clip onto circuit-panel electric wires and draw power from them. Researchers from the National Renewable Energy Laboratory (NREL) found that the technology was easy to install and is a good option for fault detection and diagnostics. View full-size infographic.

GPG Findings 003, September 2012, Advanced Power Strips for Plug Load Control. Opportunity: How much energy is lost to plug loads in U.S. commercial buildings? 25% of electricity is lost to phantom power. In efficient buildings this can increase to 50%. Technology: How do Advanced Power Strips save energy? De-energize circuits based on a timer, load-sensing, or both. Measurement and Verification: Where did M and V occur? National Renewable Energy Laboratory tested the effectiveness of 3 plug load reduction strategies in buildings throughout GSA’s Mid-Atlantic Region. Results: How did Advanced Power Strips perform in M and V? Simple timer controls most cost-effective.26% energy savings at workstations with advanced computer management in place. 48% in kitchens and printer rooms. Less than 8 years payback in all applications. Less than 1 year in kitchens and printer rooms. Deployment: Where does M and V recommend deploying Advanced Power Strips? Deploy broadly. Energy savings and low payback support deployment throughout GSA’s portfolio. [PDF - 388 KB]
