Interim ICTSB response |
|---|---|
| 1. Standardised definitionsDefinitions for power consumption should be standardised. All definitions must be reasonable, easy to apply and easy to understand. Different ICT services and devices, however, have to be treated in different ways. There must be clear definitions of different operating modes for all systems for the following modes: |
|
| a. In use/ operation (e.g. fulfilling task); | Between ON and OFF there are a number of different states not only for the purpose of power consumption. In the field of radio, these states are defined and applied to reduce radio emission.Common definitions should be sought.CENELEC??? |
| b. Waiting (e.g. for an input, action starts immediately after request); | |
| c. Sleeping (e.g. can be activated by an input signal after a certain period); | |
| d. Stand-by (e.g. can be activated by control signal); | |
| e. Off (switched off); | |
| f. Clear definitions of the following time-based performances: Average time of operation per year/ Standard use time cycle/ Start-up-time, recovery-time. | Definitions may be standardized but the purpose is not clear as these parameters are not subject for specification. |
| 2. Standard method for testing power consumptionBased on the definition of measuring conditions (e.g. voltages, temperature, input and output signals, load), a benchmark can be standardised which aims for reproducible, comparable values describing the behaviour of the device under test in an accurate and reasonable way. | Power consumption test methods are being standardized by CENELEC. This is done in the interest of public interest in the field of sustainability. |
| 3. Standardised information to the consumerBased on the definitions given above, there should be a standardised way to inform the buyer about the power consumption of a product (e.g. a standardised label). In addition, advice has to be given to the consumer on how to reduce or minimise power consumption (e.g. switching off over-night). | Standardization will not go beyond definitions and measurement methods. Limits will not be fixed by standardization. How parameter values will be presented to the consumer may be stated in a code of practice (guidance to the manufacture/operator). |
| 4. Standards for energy saving systemsDue to the tendency of ICT equipment to become integrated into systems or networks the aim of saving energy can be achieved by improving network performance. This would normally require minimal additional hardware, if any. This process should be enforced actively by: | |
| a. Standards for more energy-efficient systems (e.g. fax machine switched on by telephone system if an incoming call is detected); | These functions are widely used without having been standardized. The example may mean that the fax machine wakes-up when receiving a call. A switched-off machine may not react (see #1 for definitions) |
| b. Definition of connections and timing (e.g. minimal waiting times) for master devices (e.g. telephone systems, computers) and slave devices (e.g. fax machines, printers); | |
| c. Standard performance goals should be defined for specific pieces of apparatus or systems defining maximum permitted or recommended power consumption in stand-by or idle mode; | |
| d. Standards for defining intelligent energy management systems (e.g. auto power reduction or shut-off if a device has been idle for a specific time). Such systems are application- or device specific, and standards should define the appropriate energy management objectives. |
