agenda and goals for today s meeting
Agenda and Goals for Today’s Meeting
  • Present and discuss changes between the Draft 1 and Draft 2 specification
  • Present an overview of the test data provided by manufacturers
  • Discuss completion of the computer monitor test methodology
  • Discuss Partner Commitments, including labeling of computer monitors

GOALS:

  • Provide EPA’s rationale for the Draft 2 specification
  • Gather industry feedback on Draft 2
  • Outline next steps and a timeline for finalizing the Version 4.0 specification
time frame for how we arrived at today s meeting
Time-Frame for How We Arrived at Today’s Meeting
  • July 1999: Monitor MOU Version 3.0 went into effect
  • April 2002: Computer monitor stakeholders meeting in California. Collected feedback on Draft 1 Version 4.0 specification
  • May 2002: European computer monitor stakeholders meeting in France
  • June 2002 – February 2003: Test methodology development phase (EPA and industry)
  • February – May 2003: Data collection and testing phase (EPA and industry)
  • May – July 2003: Data analysis phase, and development of Draft 2 Version 4.0 specification (EPA)
  • July 22, 2003: Stakeholder meeting to discuss Draft 2 specification
highlights of the draft 2 specification
Highlights of the Draft 2 Specification
  • Designed to be a performance-based specification
    • Does not differentiate based on technology (CRT, LCD, etc.)
    • Recognizes best performing monitors in the marketplace (in terms of energy-efficiency)
  • Based on test data voluntarily submitted to EPA by many manufacturers
  • Includes detailed test methodology for how to test in all three modes
  • Contains Tier 1 and Tier 2 maximum allowable power consumption for On, Sleep, and Off modes
  • Allows various screen sizes, technologies, and brand-names of computer monitors to qualify under the Tier 1 requirements
  • Establishes partner commitments (to be discussed later today)
    • Labeling
    • Grandfathering
  • Provides extended effective dates to accommodate the removal of grandfathering
overview of data 1
Overview of Data {1}
  • 2 rounds of voluntary testing
    • February - April and May - June
  • 19 manufacturers represented (15 brand-names and 4 additional OEMs)
    • 49 CRTs, 40 LCDs, 1 Plasma display
  • 87 models included in analysis (3 represented models excluded due to testing at incorrect voltage/frequency combination)
overview of data 2
Overview of Data {2}
  • For perspective: Only 265 computer monitor models in 2002 with retail sales over 100 units (data from NPD)
  • 15 top selling models from Q1 2002 represented
    • 10 out of top 20 selling CRTs
    • Top 5 selling LCDs
  • Data represents 15” to 24” models and one 30” model
  • Manufacturers encouraged to submit testing data on latest, highest resolution models
    • Many models EPA has test data for are highlighted as “NEW” on manufacturer Web sites
  • Several models from data set reviewed in June 2003 issue of Consumer Reports
several minor changes to definitions
Several Minor Changes to Definitions
  • Operational mode definitions reordered and clarified
    • Now listed from highest to lowest power consumption
    • Examples of “a request from a user” are included
  • Does Version 4.0 effectively differentiate between computer monitors and televisions?
    • “A commercially available electronic product with a display screen….capable of displaying output information from a computer via one or more inputs, such as VGA, DVI, and/or IEEE 1394.”
    • Specification attempts to differentiate TVs and computer monitors based on how they are marketed and sold
  • Is it clear as to what can and cannot qualify under Version 4.0, or is further discussion needed?

Draft 2 Version 4.0

Energy-Efficiency Requirements

energy efficiency requirements
Energy-Efficiency Requirements

Tier 1 Requirements

  • On Mode:Y=33X+30
  • Sleep Mode:  4 watts
  • Off Mode:  2 watts
  • Effective Date: November 1, 2004

Tier 2 Requirements

  • On Mode: If X<1 megapixel, then Y=20; if X>1 megapixel, then Y=26X-5
  • Sleep Mode:  2 watts
  • Off Mode:  1 watt
  • Effective Date: November 1, 2005
on mode requirement tier 1
On Mode Requirement Tier 1

Set at Y=33X+30

  • Y = watts (rounded up to nearest whole number)
  • X = number of megapixels (in decimal form)
  • 60% of all monitors in EPA’s data set meet Tier 1 in On Mode

Example:

A computer monitor with 1,920,000 pixels

(resolution of 1600 x 1200) has maximum power

consumption allowance of 94 watts

33(1.92)+30=93.36 or 94 watts

sample tier 1 on mode values
Sample Tier 1 On Mode Values

* CRT = Preferred pixel format with highest resolution intended to be driven at 75 Hz

LCD = Native Resolution

sleep and off mode requirements tier 1
Sleep and Off Mode Requirements Tier 1
  • Sleep Mode:  4 watts
    • One Sleep Mode requirement
    • References to Sleep Mode Default Time have been removed from the computer monitor specification
    • 30-minute default time for Sleep Mode defined in computer agreement
      • 60-minute default time for Deep Sleep Mode not applicable
    • 87% of all monitors in EPA’s data set meet Tier 1 in Sleep Mode
  • Off Mode:  2 watts
    • 78% of all monitors in EPA’s data set meet Tier 1 in Off Mode
tier 1 line of qualification
Tier 1 Line of Qualification

17% of all CRTs qualify

90% of all LCDs qualify

49 of models meet tier 1 levels
49% of Models Meet Tier 1 Levels
  • Allows approximately 49% of all monitors from EPA’s data set to qualify for ENERGY STAR under Tier 1
    • (17% of 47 CRTs and 90% of 39 LCDs)

on mode requirement
On Mode Requirement

Set at: If X<1 megapixel, then Y=20; if X>1 megapixel,

then Y=26X-5

    • Y = watts (rounded up to nearest whole number)
    • X = number of megapixels (in decimal form)
    • 22% of all monitors in EPA’s current data set meet Tier 2 in On Mode

Example:

  • A computer monitor with 786,432 pixels (resolution of 1024 x 768) has maximum power consumption allowance of 20 watts
  • A computer monitor with 1,920,000 pixels (resolution of 1600 x 1200) has maximum power consumption allowance of 45 watts

26(1.92)-5=44.92 or 45 watts

sleep and off mode requirements
Sleep and Off Mode Requirements
  • Sleep Mode:  2 watts
    • 63% of all monitors in EPA’s current data set meet Tier 2 in Sleep Mode
  • Off Mode:  1 watt
    • 57% of all monitors in EPA’s current data set meet Tier 2 in Off Mode
    • Will harmonize with FEMP
    • Will follow 1-watt level that many ENERGY STAR specifications are moving towards
tier 2 line of qualification
Tier 2 Line of Qualification

31% of all LCDs qualify now

31% of all LCDs qualify

tier 2 qualifying models all operating modes
Tier 2 Qualifying Models: All Operating Modes
  • 14% of all monitors from EPA’s current data set qualify for ENERGY STAR
    • Tier 2 provided as an “energy-efficiency roadmap” for manufacturers – will be revisited prior to taking effect, to ensure it is still applicable to the marketplace at that time
big picture potential savings
Big Picture: Potential Savings

Projected Savings by 2010 =

  • Energy: approximately 246.7 billion kWh
  • Dollars: approximately $14 billion
  • CO2: approximately 37.6 billion lbs, or equivalent to taking approximately 2.9 million cars off the road

Per Unit Savings =

  • Energy: Up to 147 kWh annually
  • Dollars: Up to $12 - 24 annually

Notes: Savings (1) Include On, Sleep, and Off Modes, and (2) Assume CRTs are replaced

with a mix of ENERGY STAR qualified LCDs and CRTs, with increases in market penetration

going to LCDs.

removal of grandfathering language
Removal of Grandfathering Language
  • EPA has removed grandfathering language from ENERGY STAR specifications
    • Delivers on consumer expectations of high efficiency performance and energy savings
    • Ensures that ENERGY STAR's ability to differentiate more efficient products is not undermined by high percentages of labeled products qualifying at less stringent performance levels
  • EPA plans to accommodate manufacturers by extending effective dates of the Version 4.0 specification
