Concerning recent developments in the world of Advanced Power Strips (APS), Tier 2 APS
was recently added to the Michigan Energy Measures Database (MEMD)
for residential applications with a savings value of 307.1 kWh/yr. and a measure life of eight years. The MEMDi
is an online, downloadable database accessed from the Michigan Public Service Commission. Their website states, "The Michigan Energy Measures Database (MEMD) was supplied by Morgan Marketing Partners, as a basis for development of initial energy efficiency savings calculations and potential savings for energy efficiency programs.
By way of comparison, the Tier 2 APS
manages both standby power of the peripheral devices as well as active power consumption of the TV in residential applications. The Tier 2 APS
device uses an external sensor to monitor user engagement with their TV system paired with a countdown timer. When the external sensor detects a lack of user engagement, the timer starts. If there is no user engagement during the programmable length of the timer period, the Tier 2 APS
unit removes power from the TV and switched outlets. Tier 2 APS
units have a higher cost than Tier 1 units, but they deliver additional savings.
Michigan is the latest state in the nation to embrace Tier 2 APS
as a recognized savings measure for plug-load energy efficiency programs and efforts. MA, PA, OR, ID, WA, CA, and NJ have all established savings values for Tier 2 APS
. Other states such as MN, VT, and WI are also looking at Tier 2 APS
. For more information on using Tier 1 APS
