1 Rue du Rhône 114- CH-1204 Geneva - T: F: Ecma TC38 – TG2 May 2007 Kevin Fisher – Intel Corp TC38 – TG2 Convenor Ecma/TC38-TG2/2007/024 Ecma/TC38/2007/034

2 Rue du Rhône CH-1204 Geneva - T: F: Background 2003: Ecma issued the worlds 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 (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 Rue du Rhône CH-1204 Geneva - T: F: 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

4 Rue du Rhône CH-1204 Geneva - T: F: 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

5 Rue du Rhône CH-1204 Geneva - T: F: Car Analogy Energy Efficiency = Litres/Kilometre Capabilities = How many seats, A/C, electric windows, heated seats etc 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 Performance = How fast it accelerates & how fast it goes. The Information Super Highway has no speed limit. Performance is even more relevant

6 Rue du Rhône CH-1204 Geneva - T: F: Todays 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

7 Rue du Rhône CH-1204 Geneva - T: F: Concept Power Time off sleep idle active off sleep idle active Which one is more energy efficient? Hint: Add up the total area of the graphs Note: This is simplified conceptual example and represents a sum of activities in each state TodayFuture Max power regulated Metric on the total energy consumed in all states, adjusted for performance

8 Rue du Rhône CH-1204 Geneva - T: F: 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

9 Rue du Rhône CH-1204 Geneva - T: F: 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

10 Rue du Rhône CH-1204 Geneva - T: F: 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

11 Rue du Rhône CH-1204 Geneva - T: F: 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)

12 Rue du Rhône CH-1204 Geneva - T: F: 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!
