Set-Top Box Trial Uses Onset Plug Load Monitors

onset energy manageAlternative Energy Systems Consulting (AESC) will use 25 Onset HOBO Plug Load loggers to identify the energy savings potential of cable set-top box (STB) optimization.

The monitoring project will investigate the energy consumption of cable television STBs in active and passive states at 25 California locations. To identify the energy savings potential of STB optimization, AESC will monitor both power and IR remote-control activity. Using these two data streams, AESC will isolate times of active and inactive use and their respective energy consumption.

The results from the study will inform progress toward California’s energy efficiency goals.

Onset’s HOBO Plug Load data logger measures and records the power and energy consumption of 120V plug loads. It provides 0.5 percent measurement accuracy with a measurement resolution of 1 watt. More than 1,500,000 measurements will be taken over the monitoring period.

Earlier this year, the Society of Cable Telecommunications Engineers (SCTE) announced a multi-year campaign within its Energy Management Program – Energy 2020 – with the goals of reducing power consumption by 20 percent on a unit basis and reducing energy costs by 25 percent on a unit basis, all by 2020.
