Submeters and Analytics: Full Panel

New systems that integrate sensors and analytics are simplifying the submetering process and driving costs down. Researchers found that a new full-panel system was an effective solution for improving tenant billing practices and optimizing building operations via fault detection and diagnostics (FDD) and energy conservation measures (ECMs). At the testbed, comparing potential savings to installed costs yields payback under one year. View full-size infographic. [PDF - 254 KB]

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 - 254 KB]
