【Mr. Green] California begins to develop energy saving roadmap for low power mode of electronic equipment

by:MOSO     2019-12-26

California Energy Commission (CEC) Start to develop electronic equipment standby, idle or generally low power mode (LPM)Energy-saving roadmap. Although the standby power consumption of electronic equipment seems to be very small compared with active power, the penetration rate of such equipment in California residential buildings is getting higher and higher, and such equipment is idle for a long time, resulting in an increase in total energy consumption, this will not bring real value to users. On January 24, 2019, CEC held a webinar to outline the LPM roadmap, explore the scope of the proposal, review the comments received from relevant parties, and summarize the follow-up action steps.

low power mode refers to any mode other than the on-load mode in which the device performs its main functions. Road map refers to a more new energy-saving implementation method than traditional rule-making. The road map norm is voluntary and is not limited by the priority principle of federal law. Therefore, it can develop more quickly and flexibly. Although it has no regulatory effect, if the stage task is not fulfilled or there is retrogression, the road map may be transformed into a mandatory standard. The low power mode power consumption limit takes into account energy saving, cost-effectiveness and technical feasibility.

at present, this process is in the stage of data collection. In essence, this concept is used to measure the power consumption of equipment in idle state and measure the energy consumption level of secondary functions through conventional test procedures. The next step is to perform data collection on the actual product. After evaluating such data, the coverage can be modified as needed and whether the objectives defined by the specification and phase tasks have been evaluated. If the target is not reached, the coverage will be readjusted and may be converted into a formal standard.

The initial coverage of the low power roadmap includes all electrical and electronic products. It is intended to set the coverage to be broad in order to achieve greater energy conservation. However, products that have been covered by the low power mode standards of state or federal regulations, or products that have been included in other CEC roadmaps, are excluded from coverage. For example, computers, monitors, electronic displays, Furnace fans, boilers and microwave ovens are exceptional products. The horizontal method will have similar secondary functions ( For example: Display, networking, sensors, etc) The products are grouped into one group, and then the benchmark energy is established.

On June 20, 2018, CEC released a discussion document on the low power mode test program. At this seminar, feedback from relevant parties has been received and summarized, covering many topics, for example, existing test procedures, product offerings, Test status, networking traffic content, configuration requirements, sensors, wired and wireless charging, DC power supply, and shutdown mode definitions. For detailed feedback, please refer to the webinar notes posted on the CEC website.

follow-up actions include developing a data collection procedure, collecting raw data according to the procedure, and publishing analysis reports on coverage and potential opportunities.
