Energy Savings of Tier 2 Advanced Power Strips in Residential AV Systems

In this study, two Tier 2 APS models with similar control strategies were studied in 98 residential homes in SDG&E territory. The project goals were to measure and quantify the energy savings and demand reduction associated with Tier 2 APS devices, their usability, and customer acceptance. Both models eliminate standby loads of controlled AV devices and save additional energy by cutting power when no user activity is detected for a default timer setting.
