2 Session 1b: IEC 62623, test methodology for measuring energy consumption of PC products Paul W Robinson (IBM Australia) paulrob@au1.ibm.com The need for standards : Australia saw Energy Star reduced ICT energy use : AIIA hosted an ICT sustainable futures forum Australian stakeholder consultation Equipment Energy Efficiency (E3) report explores potential energy and greenhouse savings: from 3.18 to 3.52 Mt CO2 (Australia savings) from 0.37 to 0.41 Mt CO2 (New Zealand savings) : Supplementary Regulatory Impact Statement (RIS) recommends mandatory regulation for specific computers and monitors, utilising a joint A/NZ Standard based upon US ENERGY STAR 5 test method Other economies were also doing their own investigations 2 1

3 Critical elements of test methodology Need for an international standards base Needs to be widely used globally Reproducible results between test laboratories Portability of test results between economies No retesting where intent of regulations have been met Permit manufacturers to self test and certify Flexibility for a range of families of models 3 A/NZ Standards adoption/adaptation : 10 21: circulated public draft AS/NZS 5813: Part 1: Energy performance of computers, methods of measurement Part 2: minimum energy performance standards (MEPS) for computers Based on IEC post CD Rev 2, and Energy Star V5.2 Computer Specification consensus achieved in standards committee Available to the public for purchase on Plan to mandate Part 2 by

4 IEC Ed. 1 History Four years under development: 108/314/NP: IEC TC 108 project proposed on Considered ECMA 383, Energy Star 5, IEC (ICT consumption measurement) and IEC (AV consumption measurement) 108/401/CD available (Australian draft was based on documents after this point, before CDV) 108/446/CDV available Approval to circulate FDIS 108/478/RQ, Approval to include uncirculated amended short idle test procedure in FDIS TC 108 plans to circulate FDIS by Plan to publish by end of 2012 TC 108 will then hand over maintenance to another TC 5 Implementation concerns Local standards should mirror and track track international standards d A/NZ domestic standards are organised quite differently, but technically equivalent The IEC standard isn t finalised. Approval not guaranteed, as lastminute technical changes to be inserted in the FDIS without review Harmonised test methodology is vital but it should also consider other internationally or regionally harmonised frameworks: Compliance limits Test report portability Acceptability of test laboratories Exemptions for very low volume production and other factors where regulation would not save significant emissions Cross economies mutual recognition of approvals and registrations 6 3

5 Other related issues AS/NZS ITE Energy performance of internal power supplies Part 1: Methods of measurement of energy performance This recently published document draws on the following: The test method for Energy Star (computers) V5.0 and V5.2, and Similar to the test method in The Generalized Internal Power Supply Efficiency Test Protocol Rev 6.5 There are no minimum performance limits / no Part 2 AS/NZS and AS/NZS for computer monitors are under advanced development. Not explicitly based on Energy Star Displays specification Under consideration: high volume low end servers, based on Energy Star Test Method for Computer Servers 7 8 4
