China Unveils Set-Top Box Standard

Friday, March 18, 2011

China has just published its first Set-Top Box (STB) efficiency standard, GB 25957-2010. While other government agencies (i.e., ENERGY STAR, EC Code of Conduct) have already gone through multiple generations of STB efficiency programs (settling on a methodology that limits the total typical energy consumption (TEC) in kWh that a complex STB consumes annually), China [...]

A New Lullaby for Set-top Boxes?

Monday, January 3, 2011

The US EPA got closer to finalizing the next ENERGY STAR set-top box (STB) efficiency program requirements with an addition that will allow the devices to go into a much lower power down mode than previous versions. As covered in previous blogs, reigning in STB power consumption has proven to be a little trickier than [...]

An Update on California’s New Mandatory TV Spec

Thursday, September 23, 2010

September 7, 2010 – Last fall, I wrote about the California Energy Commission (CEC) approving the first mandatory TV efficiency standard (see my blog from November 18, 2009). At the time, the CEC had just unanimously voted to amend the state’s Appliance Efficiency Regulations (Title 20) to include tighter energy efficiency standards for televisions. On [...]

China Tunes In to a New TV Efficiency Standard

Friday, August 13, 2010

China has officially joined the battle in reducing large screen flat panel TV energy consumption.  The new standard, GB 24850-2010, published in June, becomes effective on December 1, 2010. The specifications include the usual components – standby power consumption and active mode efficiency/power consumption. But while the standby power limits (see Table 1) fall in line [...]
