2. Background 2003: Ecma issued the world’s first environmentally conscious design standard (ECMA-341) for the ICT & CE industries • Aimed at the designer, provides pragmatic advice on how to reduce the environmental footprint of a product at design stage. ECMA-341 is incomplete when it comes to the energy efficiency section • A significant gap for the ICT & CE industry is how to measure the true energy efficient performance of a given product. • ECMA-341 now adopted by IEC TC108 as IEC 62075 (FDIS in the summer). EE part still incomplete. TC38-TG2 formed with a scope of “Energy Efficiency” • The initial focus of the Ecma work is at a system level for desktop and notebook (in AC mode) computers.

3. Measuring Energy Efficient Performance Fridge Energy Efficient Performance = Cubic Capacity Energy used to get it cold + energy use to sustain temperature over a given time Computer Energy Efficient Performance Rue du Rhône 114 - CH-1204 Geneva - T: +41 22 849 6000 - F: +41 22 849 6001 - www.ecma-international.org 3

4. Definitions Energy Efficient Performance (EEP) • The intersection of product performance, capabilities and energy efficiency Performance • Compute throughput and responsiveness at a component or system level.   Capabilities • Is a feature or set of features that enhances usability and/or experience of a Product Energy Efficiency • The AC Energy consumed while executing a duty cycle measured in KW-Hr. • Use power more efficiently during periods of activity • Use as little power as possible when not active • Components/devices should drop into low power modes as often and as deep as possible Rue du Rhône 114 - CH-1204 Geneva - T: +41 22 849 6000 - F: +41 22 849 6001 - www.ecma-international.org 4

5. Car Analogy Performance = How fast it accelerates & how fast it goes. Energy Efficiency = Litres/Kilometre Capabilities = How many seats, A/C, electric windows, heated seats etc The Information Super Highway has no speed limit. Performance is even more relevant • Classifications: • A motorbike and a Smart car are very • energy efficient, but not great for sales • people (unless selling pizzas!) or a family • of six • A 4 X 4 is great for off road, but • inefficient for the school run Rue du Rhône 114 - CH-1204 Geneva - T: +41 22 849 6000 - F: +41 22 849 6001 - www.ecma-international.org 5

6. Today’s energy regulation for computers Puts arbitrary limits on energy consumed in different power states • Sleep state • Idle mode Is this good for • Innovation? Limits technology to do more while in sleep • The environment? Does it really encourage more efficient designs and user behaviour? Fails to account for 2 out of the 3 tenets of energy efficiency. A more holistic approach is required Rue du Rhône 114 - CH-1204 Geneva - T: +41 22 849 6000 - F: +41 22 849 6001 - www.ecma-international.org 6

7. Concept Which one is more energy efficient? Hint: Add up the total area of the graphs active active Max power regulated Today Future idle Metric on the total energy consumed in all states, adjusted for performance idle Power Max power regulated sleep sleep off off Time Note: This is simplified conceptual example and represents a sum of activities in each state Rue du Rhône 114 - CH-1204 Geneva - T: +41 22 849 6000 - F: +41 22 849 6001 - www.ecma-international.org 7

TC38-TG2 Details Membership • Industry: AMD, Apple, Dell, HP, IBM, Intel, Lexmark, Microsoft, NVIDIA, Sony, Toshiba, VIA Technologies • EU Gov: AEA Technology (UK), EC consultant • EPA Consultants: ECOS, ICF, LBNL, Terra Novum Meetings • Every two weeks via teleconference • Ad hoc FTF. Next planned June 19 / 20 in Washington DC Rue du Rhône 114 - CH-1204 Geneva - T: +41 22 849 6000 - F: +41 22 849 6001 - www.ecma-international.org 8

9. TC38 – TG2 Standard • Three components to the standard • System classification • Compute performance and capability measurements • Energy consumption over a defined workload / duty cycle per classification • Overview of the Ecma Standard Rue du Rhône 114 - CH-1204 Geneva - T: +41 22 849 6000 - F: +41 22 849 6001 - www.ecma-international.org 9

10. Benchmark and Milestones BAPCo (http://www.bapco.com/) selected as vendor for Benchmark Software • EECoMark™ under development Ecma standard provides criteria for BM to comply + approval process Milestones • Standard ready for approval at December General Assembly • Energy Star Tier II January 2009 Rue du Rhône 114 - CH-1204 Geneva - T: +41 22 849 6000 - F: +41 22 849 6001 - www.ecma-international.org 10

11. Users of Methodology Ecma developing the test methodology • Standardises test process and results reporting enables comparison of results • Does not provide pass / fail criteria (e.g. limits) Users • US EPA for Energy Star (ES has partnership agreements with Asian, N. & S. American and European nations) • EU for EuP directive • Other countries: Japan Top-runner? • End users (IT managers etc) Rue du Rhône 114 - CH-1204 Geneva - T: +41 22 849 6000 - F: +41 22 849 6001 - www.ecma-international.org 11

12. Conclusions Measuring the EEP of a computer is exponentially more complicated than that of a fridge • Ecma developing test methodology supported by a benchmark (BAPCo developing EECoMark in parallel) • EPA is initially the primary target for the work, but is just one user • Broad industry and regulator (EPA and EC) support for the work Imagine: A computer that goes to sleep in-between key strokes! This may not be possible, however the Ecma methodology is designed to give the innovative power back to the designer to at least allow him to try!
