55	Commitment

56	The following are the terms of the ENERGY STAR Partnership Agreement as it pertains to the

57	manufacturing of ENERGY STAR qualified computers. The ENERGY STAR Partner must adhere to the

58	following program requirements:

59

60	• comply with current ENERGY STAR Eligibility Criteria, defining the performance criteria that must be

61	met for use of the ENERGY STAR certification mark on computers and specifying the testing criteria

62	for computers. EPA may, at its discretion, conduct tests on products that are referred to as ENERGY

63	STAR qualified. These products may be obtained on the open market, or voluntarily supplied by

64	Partner at EPA's request;

65

66	• comply with current ENERGY STAR Identity Guidelines, describing how the ENERGY STAR marks

67	and name may be used. Partner is responsible for adhering to these guidelines and for ensuring that

68	its authorized representatives, such as advertising agencies, dealers, and distributors, are also in

69	compliance;

70

71	• qualify at least one ENERGY STAR computer model within one year of activating the computers

72	portion of the agreement. When Partner qualifies the product, it must meet the specification (e.g., Tier

73	1 or 2) in effect at that time;

74

75	• provide clear and consistent labeling of ENERGY STAR qualified computers. The ENERGY STAR

76	mark must be clearly displayed on the top/front of the product, in product literature (i.e., user manuals,

77	spec sheets, etc.), on product packaging, and on the manufacturer's Internet site where information

78	about ENERGY STAR qualified models is displayed;

79

80	- If information concerning ENERGY STAR is provided on the Partner Web site as specified by

81	the ENERGY STAR Web Linking Policy (this document can be found in the Partner

82	Resources section on the ENERGY STAR Web site at www.eneravstar.gov). EPA may

83	provide links where appropriate to the Partner Web site;

84

85	Electronic Labeling Option: Manufacturers have the option of using an alternative electronic labeling

86	approach in place of the product labeling requirement above, as long it meets the following

87	requirements:

88

89

95

96

97	EPA will consider alternative proposals for electronic labeling on a case-by-case basis.

98

ENERGY STAR Program Requirements for Computers: Draft 2 Version 4.0	2

The ENERGY STAR mark in cyan, black, or white (as described in The ENERGY STAR
Identity" available at www.energystar.gov/logos'). appears at system start-up. The electronic
mark will display for a minimum of 10 seconds, unless the product turn-on process does not
allow this. In this case the mark should show for as much time as possible, but for no less
than 5 seconds.

The ENERGY STAR mark must be at least 10% of screen size, may not be smaller than 76
pixels x 78 pixels, and must be legible.


-------
Note: EPA received a number of comments regarding product labeling, including making it a voluntary
requirement and eliminating the requirement. One of the purposes of including the ENERGY STAR
mark on the product is to increase ENERGY STAR brand recognition and to assure the consumer that
by purchasing this product they are taking steps to save energy and help the environment. EPA feels
that offering an electronic labeling approach meets EPA's goals while also considering manufacturer
design restraints and preferences. EPA is interested in hearing manufacturer feedback on the
proposed electronic labeling requirements.

99

100	• provide to EPA, on an annual basis, an updated list of ENERGY STAR qualified computer models.

101	Once the Partner submits its first list of ENERGY STAR qualified computer models, the Partner will be

102	listed as an ENERGY STAR Partner. Partner must provide annual updates in order to remain on the

103	list of participating product manufacturers;

104

105	• provide to EPA, on an annual basis, unit shipment data or other market indicators to assist in

106	determining the market penetration of ENERGY STAR. Specifically, Partner must submit the total

107	number of ENERGY STAR qualified computers shipped (in units by model) or an equivalent

108	measurement as agreed to in advance by EPA and Partner. Partner is also encouraged to provide

109	ENERGY STAR qualified unit shipment data segmented by meaningful product characteristics (e.g.,

110	capacity, size, speed, or other as relevant), total unit shipments for each model in its product line, and

111	percent of total unit shipments that qualify as ENERGY STAR. The data for each calendar year

112	should be submitted to EPA, preferably in electronic format, no later than the following March and may

113	be provided directly from the Partner or through a third party. The data will be used by EPA only for

114	program evaluation purposes and will be closely controlled. Any information used will be masked by

115	EPA so as to protect the confidentiality of the Partner;

116

117	• notify EPA of a change in the designated responsible party or contacts for computers within 30 days.

118

119

120	Performance for Special Distinction

121	In order to receive additional recognition and/or support from EPA for its efforts within the

122	Partnership, the ENERGY STAR Partner may consider the following voluntary measures and should keep

123	EPA informed on the progress of these efforts:

124

125	• consider energy efficiency improvements in company facilities and pursue the ENERGY STAR mark

126	for buildings;

127

128	• purchase ENERGY STAR qualified products. Revise the company purchasing or procurement

129	specifications to include ENERGY STAR. Provide procurement officials' contact information to EPA

130	for periodic updates and coordination. Circulate general ENERGY STAR qualified product information

131	to employees for use when purchasing products for their homes;

132

133	• ensure the power management feature is enabled on all ENERGY STAR qualified monitors and

134	computers in use in company facilities, particularly upon installation and after service is performed;

135

136	• provide general information about the ENERGY STAR program to employees whose jobs are relevant

137	to the development, marketing, sales, and service of current ENERGY STAR qualified product

138	models;

139

140	• provide a simple plan to EPA outlining specific measures Partner plans to undertake beyond the

141	program requirements listed above. By doing so, EPA may be able to coordinate, communicate,

142	and/or promote Partner's activities, provide an EPA representative, or include news about the event in

143	the ENERGY STAR newsletter, on the ENERGY STAR Web pages, etc. The plan may be as simple

144	as providing a list of planned activities or planned milestones that Partner would like EPA to be aware

145	of. For example, activities may include: (1) increase the availability of ENERGY STAR qualified

146	products by converting the entire product line within two years to meet ENERGY STAR guidelines; (2)

ENERGY STAR Program Requirements for Computers: Draft 2 Version 4.0	3


-------
147	demonstrate the economic and environmental benefits of energy efficiency through special in-store

148	displays twice a year; (3) provide information to users (via the Web site and user's manual) about

149	energy-saving features and operating characteristics of ENERGY STAR qualified products: and (4)

150	build awareness of the ENERGY STAR Partnership and brand identity by collaborating with EPA on

151	one print advertorial and one live press event;

152

153	• provide quarterly, written updates to EPA as to the efforts undertaken by Partner to increase

154	availability of ENERGY STAR qualified products, and to promote awareness of ENERGY STAR and

155	its message.

Below is the DRAFT 2 Version 4.0 product specification for ENERGY STAR qualified computers. A
product must meet all of the identified criteria to earn the ENERGY STAR.

1) Definitions: Below are the definitions of the relevant terms in this document.

A. Computer: A device which performs logical operations and processes data. Computers are
composed of, at a minimum: (1) a central processing unit (CPU) to perform operations; (2) user
input devices such as a keyboard, mouse, digitizer or game controller; and (3) a display screen to
output information. For the purposes of this specification, computers include both stationary and
portable units, including desktop computers, gaming consoles, integrated computers, notebook
computers, tablet PCs, desktop-derived servers and workstations.

Note: The definition for "computer" has been rewritten to be more specific to functionality and capability in
addition to form factor and product types.

175

176	Components

177

178	B. Display: A commercially-available, electronic product with a display screen and its associated

179	electronics encased in a single housing, or within the computer housing (e.g., notebook or

180	integrated computer), that is capable of displaying output information from a computer via one or

181	more inputs, such as a VGA, DVI, and/or IEEE 1394. Examples of display technologies are the

182	cathode-ray tube (CRT) and liquid crystal display (LCD).

183

184	C. External Power Supply: A component contained in a separate physical enclosure external to the

185	computer casing and designed to convert line voltage ac input from the mains to lower voltage dc

186	output for the purpose of powering the computer. An external power supply must connect to the

187	computer via a removable or hard-wired male/female electrical connection, cable, cord or other

188	wiring and have a nameplate output power less than or equal to 250 watts.

189

190	D. Internal Power Supply: A component internal to the computer casing and designed to convert ac

191	voltage from the mains to dc voltage(s) for the purpose of powering the computer components.

192	For the purposes of this specification, an internal power supply must be contained within the

193	computer casing but be separate from the main computer board. The power supply must connect

194	to the mains through a single cable with no intermediate circuitry between the power supply and

195	the mains power. In addition, all power connections from the power supply to the computer

196	components must be internal to the computer casing (i.e., no external cables running from the

197	power supply to the computer or individual components). Internal dc to dc converters used to

198	convert a single dc voltage from an external power supply into multiple voltages for use by the

199	computer are not considered internal power supplies.

Note: The external power supply definition has been expanded to provide further clarification and to be
consistent with the ENERGY STAR external power supply specification. Unlike the external power supply
specification, both single voltage and multiple voltage power supplies are covered by this computer
specification. In the case where a computer comes with a multiple voltage external power supply,
manufacturers will be required to use the loading requirements provided in the internal power supply test
procedure for ENERGY STAR qualification (refer to Section 4, Testing). Finally, an internal power supply is
further defined as "separate from the main computer board" to support the requirements of the Internal Power
Supply Test Protocol.

ENERGY STAR Program Requirements for Computers: Draft 2 Version 4.0	5


-------
200	Computer Types

201

202	E. Desktop Computer: A computer where the main unit is intended to be located in a permanent

203	location often on a desk or on the floor. Desktops are not designed for portability and utilize an

204	external monitor, keyboard, and mouse. Desktops are designed for a broad range of home and

205	office applications including, email, web browsing, word processing, standard graphics

206	applications, gaming, etc.

207

208	F. Desktop-Derived Server: A desktop-derived server is a computer that typically uses desktop

209	components in a tower form factor, but is designed explicitly to be a host for other computers or

210	applications. For the purposes of this specification, a computer must be marketed as a server and

211	have the following characteristics to be considered a desktop-derived server:

212

213	• Designed and placed on the market as a Class B product per EuroNorm EN55022:1998 under

214	the EMC Directive 89/336/EEC and has no more than single processor capability (1 socket on

215	board).

216

217	• Designed in a pedestal, tower, or other form factor similar to those of desktop computers such

218	that all data processing, storage, and network interfacing is contained within one box/product.

219

220	• Designed to operate in a high-reliability, high-availability application environment where the

221	computer must be operational 24 hours/day and 7 days/week, and unscheduled downtime is

222	extremely low (on the order of hours/year).

223

224	• Capable of operating in a simultaneous multi-user environment serving several users through

225	networked client units.

226

227	• Shipped with an industry accepted operating system for standard server applications (e.g.,

228	Windows NT, Windows 2003 Server, Mac OS X Server, OS/400, OS/390, Linux, Unix and

229	Solaris).

230

231	Desktop-derived servers are designed to perform functions such as processing information for

232	other systems, providing network infrastructure services (e.g., archiving), data hosting and running

233	webservers.

234

235	This specification does not cover mid-range or large servers, defined for purposes of this

236	specification as:

237

238	• Designed and placed on the market as a Class A product per EuroNorm EN55022:1998 under

239	the EMC Directive 89/336/EEC and designed and capable of having a single or dual

240	processor capability (1 or greater sockets on board).

241

242	• Designed and placed on the market as a Class B product per EuroNorm EN55022:1998 under

243	the EMC Directive 89/336/EEC and designed and capable of having a minimum dual

244	processor capability (2 sockets on board).

245

246	G. Game Consoles: Stand alone computers whose primary use is to play video games. For the

247	purposes of this specification, game consoles must use a hardware architecture based on typical

248	computer components (e.g., processors, system memory, video architecture, optical and/or hard

249	drives, etc.). The primary input for game consoles are special hand held controllers rather than

250	the mouse and keyboard used by conventional computer types. Game consoles are also

251	equipped with audio visual outputs for use with televisions as the primary display, rather than an

252	external monitor or integrated display. These devices do not typically use a conventional

253	operating system, but often perform a variety of multimedia functions such as: DVD/CD playback,

254	digital picture viewing, and digital music playback.

ENERGY STAR Program Requirements for Computers: Draft 2 Version 4.0	6


-------
255

256	H. Integrated Computer System: A desktop system in which the computer and display are combined

257	into a single unit. Integrated computers must meet all of the following criteria: (1) it is not possible

258	to measure the power consumption of the two components separately by disconnecting external

259	cables or using mechanical switches; and (2) the system receives its ac power through a single

260	cable. As a subset of desktop computers, integrated computers are typically designed to provide

261	similar functionality as desktop systems.

262

263	I. Notebook and Tablet Computers: A computer designed specifically for portability and to be

264	operated for extended periods of time without a direct connection to an ac power source.

265	Notebooks and tablets must utilize an integrated monitor and be capable of operation off an

266	integrated battery or other portable power source. In addition, most notebooks and tablets use an

267	external power supply and have an integrated keyboard and pointing device, though tablets use

268	touch sensitive screens. Notebook and tablet computers are typically designed to provide similar

269	functionality to desktops except within a portable device. For the purposes of this specification,

270	docking stations are considered accessories and, therefore, the performance levels associated

271	with notebooks presented in Table 1, below, do not include them.

272

273	J. Workstation: For the purposes of this specification, to qualify as a workstation, a computer must:

274	(1) ship with Error-Correcting Code (ECC) memory; (2) ship with buffered or registered DIMMs; (3)

275	be marketed as a workstation; (4) be equipped with multiple graphics cards or at least 256 MB of

276	video RAM; and (5) meet the minimum number of criteria indicated in the categories listed below:

277

278	Performance (must meet minimum of 3)

279

280	Ships with:

281	• 2 or more qualified Independent Software Vendor (ISV) products on the system

282	• A striped RAID configuration

283	• SCSI or SAS disks and controllers

284	• 3 or more serial IDE/SATA drives

285	• Stereoscopic video output (e.g., 3-dimensional display)

286	• Multi-graphical processing unit (GPU) (ex: SLI or CrossFire)

287	• Dual Gigabit Ethernet

288	• Capable of shipping with 2 or more processor packages, or 4 or more cores

289

290	Reliability (must meet minimum of 1)

291

292	Ships with:

293	• Configurations with calculated system Mean Time Between Failures (MTBF) of 25,000 hours

294	or more

295	• A mirrored RAID hard drive configuration

296

297	Availability (must meet minimum of 1)

298

299	Ships with:

300	• Grid resource management software

301

302	• Remote management clients like SNMP, SRS, etc., installed

303

ENERGY STAR Program Requirements for Computers: Draft 2 Version 4.0	7


-------
Note: In response to concerns regarding the blurred line between high capability desktops and workstations,
the definition for workstations has been tightened to include the following required, instead of optional,
characteristics as proposed in the previous draft version: Error-Correcting Code memory; buffered or
registered DIMMs; marketed as a workstation; and equipped with advanced graphics. Availability
requirements were also added in response to industry comments that this feature is important and unique to
workstations.

EPA also received a suggestion to include the use of a minimum 450 rated watts power supply in the
workstation definition. Recognizing that computers overall are becoming more powerful and that power supply
oversizing is a concern in desktop designs, EPA is reluctant to include this as a characteristic of a workstation.

306

307	Operational Modes

308

309	K. Idle State: For purposes of testing and qualifying computers under this specification, this is the

310	state in which the operating system and other software have completed loading, the machine is

311	not asleep, and activity is limited to those basic applications that the system starts by default.

312

313	L. Sleep Mode: A low power state that the computer is capable of entering automatically after a

314	period of inactivity or by manual selection. A computer with sleep capability can quickly "wake" in

315	response to network connections or user interface devices. For the purposes of this specification,

316	Sleep mode correlates to ACPI System Level S3 (suspend to RAM) state, where applicable.

317

318	M. Standby Level (Off Mode): The power consumption level in the lowest power mode which cannot

319	be switched off (influenced) by the user and that may persist for an indefinite time when the

320	appliance is connected to the main electricity supply and used in accordance with the

321	manufacturer's instructions. For purposes of this specification, Standby correlates to ACPI

322	System Level S4 or S5 states, where applicable.

323

324	Networking and Power Management

325

326	N. Network Interface: The components (hardware and software) whose primary function is to make

327	the computer capable of communicating over one or more network technologies. For purposes of

328	testing to this specification, Network Interface refers to the IEEE 802.3 wired Ethernet interface.

329

330	O. Wake Event: A user, programmed, or external event or stimulus that causes the computer to

331	transition from Sleep or Standby to active mode of operation. Examples of wake events include,

332	but are not limited to, movement of the mouse, keyboard activity, or a button press on the chassis,

333	and in the case of external events, stimulus conveyed via a remote control, network, modem, etc.

334

335	P. Wake-On LAN (WOL): Functionality which allows a computer to wake from Sleep or Standby

336	when directed by a network request.

Note: The definition for network interface was modified to indicate that this refers to a wired Ethernet
connection as specified by IEEE 802.3. In addition, a definition for WOL was added to clarify that, for the
purposes of this specification, this term is used for both Sleep and Standby. The wake event definition was
also modified to reflect this clarification.

337

338	2) Qualifying Products: Computers must meet the computer definition as well as one of the

339	product type definitions provided in Section 1, above, to qualify as ENERGY STAR. Please note that

340	EPA will explore additional computer types, such as thin clients, for potential Tier 2

341	requirements. The following table provides a list of the types of computers that are (and are not)

342	eligible for ENERGY STAR.

ENERGY STAR Program Requirements for Computers: Draft 2 Version 4.0


-------
343

Products Covered by Version 4.0
Specification

Products Not Covered by Version 4.0
Specification

•	Desktop Computers

•	Game Consoles

•	Integrated Computer Systems

•	Notebook Computers/Tablet PCs

•	Desktop-Derived Servers

•	Workstations

•	Mid-Range and Large Servers (as
defined in Section 1F)

•	Thin Clients/Blade PCs

•	Handhelds and PDAs

344 	

Note: EPA has removed specific references to clamshell and multimedia computers from this draft. In
order to qualify for ENERGY STAR, these product types will be required to meet the definitions provided
in Section 1, which are now more heavily weighted by functionality and capability as opposed to product
type and form factor. EPA may revisit multimedia computers based on growth of this product category
and sufficient evidence provided by manufacturers that these computers possess unique characteristics
that require further separation from the desktop computer category.

EPA has not included power allowances for thin clients for Tier 1 for the following reasons: (1) limited data
and/or interest on behalf of manufacturers for these products; (2) small market penetration within the U.S.;
and (3) dependency on a central server system for computing power. This product category continues to
be of interest to international partners of the ENERGY STAR program, such as the European Union, and
therefore, EPA will continue to monitor market growth and begin researching thin clients for consideration
under Tier 2.

345

346	3) Energy Efficiency and Power Management Criteria: Computers must meet the

347	requirements below to qualify as ENERGY STAR. Proposed effective dates for Tier 1 and Tier 2 are

348	covered in Section 5 of this specification.

349

350	A) Tier 1 Requirements - Effective July 1. 2007

351

352	(1) Power Supply Efficiency Requirements

353

354	Computers Using an Internal Power Supply: 80% minimum efficiency at 20%, 50%, and 100% of

355	rated output and Power Factor > 0.9 at 100% of rated output.

356

357	Computers Using an External Power Supply: Must be ENERGY STAR qualified or meet the no-

358	load and active mode efficiency levels provided in the ENERGY STAR Program Requirements for

359	Single Voltage Ac-Ac and Ac-Dc External Power Supplies. The ENERGY STAR specification and

360	qualified product list can be found at www.enerqvstar.gov/powersupplies. Note: This performance

361	requirement also applies to multiple voltage output external power supplies as tested in accordance to

362	the Internal Power Supply test method referenced in Section 4, below.

363

Note: EPA is proposing that all computers (i.e., desktop-derived servers and workstations) meet the Tier 1 80%
efficient internal power supply requirement. Manufacturers of desktop-derived servers and workstations that
have concerns regarding the inclusion of these product categories under this requirement are encouraged to
provide comments and data that supports the need to separate out their requirements.

It was brought to EPA's attention that some computers may be designed with a multi-voltage external power
supply. To address these product types, EPA is requiring that computers equipped with multi-voltage external
power supplies meet the ENERGY STAR external power supply performance levels at no-load and active
mode, using the load requirements provided in the Internal Power Supply Test Procedure.

ENERGY STAR Program Requirements for Computers: Draft 2 Version 4.0


-------
364	(2) Operational Mode Efficiency Requirements

365

366	For the purposes of determining Idle state levels, desktops and integrated computers must qualify

367	under Category A or Category B as defined below:

368

369	Category A: Category A represents desktops with a significant level of increased capability. In

370	order to qualify as Category A, a desktop must meet at least 4 of the following characteristics:

371	• Multiple processors installed

372	• 4 or more cores on a single processor

373	• 2 or more graphics processing units (GPUs) or a single GPU with > 128 MB RAM

374	• HDTV capable video outputs

375	• TV tuner

376	• 2 or more internal hard disk drive

377	• 2 GB or more of installed RAM

378

379	Category B: Category B is the default category for all desktops. All desktop computers that do

380	not meet the requirements of Category A above will be considered under Category B for ENERGY

381	STAR qualification. Desktops in Category B often share the following set of common features:

382	• One processor with one or two cores

383	• One hard drive

384	• Maximum of one optical drive

385	• 1 GB of RAM or less

386	• A GPU with a single monitor output and < 128 MB dedicated video memory, often integrated

387	on the motherboard

Note: In an attempt to further delineate desktop computers based on capability, EPA has developed two
categories of products: Category A, which is meant to cover computers designed specifically for increased
capabilities and Category B, which is meant to cover all other desktop computers. Further justification and data
supporting the proposed Idle power allowances associated with these categories of products are provided in the
rationale document titled "Rationale for Data Analysis of Idle Power Levels for the Draft 2 ENERGY STAR
(Version 4.0) Computer Specification".

EPA is continuing to have discussions with the Standard Performance Evaluation Corporation (SPEC) to
determine if an existing or future benchmark can be used to delineate desktops for purposes of Idle. However,
at the time of the completion of this draft specification, EPA and SPEC are still exploring means for resolving
concerns related to access to the tool by all wishing to qualify products for ENERGY STAR. As such, EPA has
included the much more refined product delineation approach noted above which reflects the input of numerous
manufacturers. EPA will update stakeholders on discussions with SPEC, as appropriate.

388

389	The following tables indicate the required power allowances for the Tier 1 specification. Table 1 gives

390	the baseline requirements, while Table 2 gives additional power allowances for WOL and increased

391	system memory. For those products that meet the WOL and memory requirements, a model must

392	meet the energy level provided in Table 1 summed with the appropriate allowances from Table 2.

393	Note: Products whose Sleep levels meet the Standby power requirements do not need to have

394	a distinct Off mode, and may qualify for this specification using only Sleep mode.

400

401	Standby: Computers should be tested and reported as shipped for Standby. Models which will be

402	shipped with WOL enabled should be tested with WOL enabled and will qualify using the extra

403	allowance for Standby found in Table 2.

404

405	Sleep: Computers should be tested and reported as shipped for Sleep. Models sold through

406	enterprise channels, as defined in the Tier 1 Power Management Requirements (Section 3.A.3),

407	shall be tested, qualified, and shipped WOL enabled, while products going directly to consumers

408	through normal retail channels may be tested, qualified, and shipped with WOL disabled. Those

409	models sold both through enterprise channels and directly to consumers must test and meet both

410	the levels with and without WOL.

ENERGY STAR Program Requirements for Computers: Draft 2 Version 4.0	11


-------
Note:

Capability Adders: In response to stakeholder comments about Sleep and Standby levels, EPA has included
two increased power allowances for WOL functionality and installed system memory. Enabling of WOL
functionality is no longer universally required for Sleep or Standby, but rather is now required for S3 or Sleep for
units destined for enterprise settings. WOL enabling is not required for units being shipped directly to
residential customers. In revising the requirement as reflected in this draft, EPA believes that the specification
will further power management in the most efficient manner. After further testing and the analysis of data
submitted by manufacturers, EPA has determined the above level as an appropriate additional power allowance
for WOL functionality.

Stakeholders also commented that the power consumption in Sleep is heavily dependant on the amount of
RAM installed in the system. For this reason, EPA studied the available data and found that the increase in
power is related to the number of RAM modules. Thus, EPA has included a capability adder for extra memory
modules over two installed in the system.

Power Levels: EPA has carefully analyzed available data, including additional data provided by manufacturers,
and has proposed modified power levels for Sleep and Standby. This analysis included the removal of
platforms which will no longer be available once the specification becomes effective. Where feasible, EPA has
consolidated and rounded power levels to help simplify the requirements proposed by this specification. Wth
the addition of the capability adders for WOL and additional memory, EPA believes that these new levels are
reasonable and achievable based on presently available data.

Further analysis, using the new desktop delineation and industry supplied data, supported the inclusion in this
draft of previous Idle levels for notebooks and desktops. Though a 75 watt idle level appears to be defensible
for Category A systems, more data are needed on the Idle power consumption of systems that include those
features. EPA asks that stakeholders share data with EPA relevant to products with Category A features as
soon as possible.

Desktop-Derived Servers: EPA has received limited data on this product type and, as such, this specification
treats them as advanced capability computers with special functionality. Desktop-derived servers are now
required to meet the same power supply, Idle, and Standby requirements as desktops under the Category A
designation. Since desktop-derived servers are intended for a high-availability application environment, a Sleep
level requirement is not applicable. EPA may reconsider these levels if stakeholders provide additional data to
show alternate levels that are more appropriate for these product types.

Game Consoles: Over the last several weeks, EPA has tested previous and current generation gaming
systems to determine which operational modes and efficiency levels to propose for these products. Component
specifications for current generation game consoles are most similar to those found in advanced capability
systems (Category A), as defined by this specification. EPA may consider delineating game consoles similar to
desktops if sufficient data and information supporting this need is submitted for consideration. Only game
consoles that meet the required characteristics for Category A products may qualify for ENERGY STAR at this
time. This proposed Tier 1 requirement is based on data for the newest products available at the time of the
development of this draft. EPA would like feedback on the treatment of these products reflected in this draft.
EPA also expects to include a more refined approach to this product category in Tier 2 of this computer
specification.

Integrated Computers: After further testing and review, EPA has determined that additional power allowances
for integrated computers are unnecessary. EPA believes that these products can meet the appropriate levels
for desktops for the following reasons: (1) the monitor remains asleep during all testing and data collection; (2)
integrated computers often use a single power supply for both the computer and display; and (3) because their
typically closed form factor eliminates the need to account for future upgrades (e.g., increased memory,
aftermarket GPU, etc.); and 4) limited data shared by stakeholders does not support additional allowances.
EPA is open to considering additional power allowances if sufficient data is provided to show the need for such
allowances.

ENERGY STAR Program Requirements for Computers: Draft 2 Version 4.0	12


-------
Notebook Computers and Tablets: Some stakeholders expressed a need for notebooks to be categorized by
performance in a similar manner to desktops. EPA's current data set shows that notebook Idle levels are much
more consistent than desktop levels, as manufacturers use the most advanced technology to reduce energy
consumption and extend the battery life of portable units. For this reason, EPA believes it is appropriate to
maintain this single level which is achievable for models at a variety of capability levels.

Workstations: Some manufacturers had initial concerns with the levels proposed in the previous version being
too stringent and responded with data supporting their claims. Upon closer review, and the elimination from the
data set of platforms that likely will no longer be available once the specification becomes effective, the data
supports the previously proposed Standby levels and the modestly increased Sleep levels proposed above.

WOL Enabling for Qualification: EPA's intent is to have products tested in a way that is consistent with their
use in the market. To this end, all computers must be tested "as shipped". With WOL no longer required for
Standby and only required for enterprise channels for Sleep, as defined in the Tier 1 Power Management
Requirements found in section 3.A.3 below, EPA feels the above requirements give manufacturers the required
flexibility to test and report units as they are intended to be configured in their particular market. For those
computers that are targeted and shipped to enterprise customers, manufacturers will be required to test and
qualify the models with WOL enabled. In those cases where a particular model is shipped to both the consumer
and enterprise channels, EPA is requiring that it be tested and qualified with and without WOL enabled. For
Standby power, manufacturers are not required to enable WOL and may elect to test with or without WOL
enabled, as determined by how the product is shipped. EPA seeks feedback on the viability of above the
proposed testing approach.

412

413	(3) Power Management Requirements

414

415	Shipment Requirement:

416	Products must be shipped with the display's Sleep mode set to activate within 15 minutes of user

417	inactivity. Products must be shipped with the computer's Sleep mode set to activate within 30 minutes

418	of user inactivity. Products may have more than one low power mode but these proposed criteria

419	address Sleep mode as defined in this specification. Computers shall reduce the speed of any active

420	Ethernet network links to the lowest speed supported by both ends of the link when transitioning to

421	Sleep or Standby.

422

423	All computers, regardless of distribution channel, shall have the ability to enable and disable WOL for

424	Sleep mode. Systems shipped through enterprise channels must have Wake On LAN (WOL) enabled

425	from the Sleep mode. For the purpose of this specification, "enterprise channels" are defined as sales

426	channels normally used by large and medium-sized business, government organizations, and

427	educational institutions, with the intent of identifying machines that will be used in managed client/

428	server environments. With WOL enabled, any directed packet filters shall be enabled and set to an

429	industry standard default configuration.

430

431	All machines shipped to enterprise customers shall be capable of both remote and scheduled wake

432	events from Sleep mode and manufacturers shall ensure that these settings, where the manufacturer

433	has control (i.e., configured through hardware settings rather than software settings), can be managed

434	centrally with tools provided by the manufacturer.

Note: Network card speed scaling is already present in the market and should be readily accomplished by
simple coordination with the BIOS. The most common example of this will be to drop 1 Gb/s NICs (operating
at 1 Gb/s or 100 Mb/s) to 10 Mb/s. Systems will generally revert to full speed when returning from Sleep or
Standby. While present Ethernet standards lead to a several second transition time for these link rate
changes, this should be masked by system transition time and so should not impair user experience.

EPA recognizes that there are emerging technologies such as Out-Of-Bound (OOB) client management
tools that are more sophisticated than WOL. These emerging technologies are expected to aid in power
management but are also expected to increase power consumption when turned on. EPA further
understands that many such technologies are and will continue to be disabled when shipped. It is EPA's
intent to require products be tested as shipped for purposes of qualifying for ENERGY STAR. Due to a lack
of data and information on these emerging technologies, EPA has chosen not to specifically address these
technologies under Tier 1 of this specification. EPA will reinvestigate these capabilities in development of
Tier 2 of this specification, if needed.

ENERGY STAR Program Requirements for Computers: Draft 2 Version 4.0	13


-------
435	User Education Requirement: In order to ensure that purchasers/users are properly educated on the

436	benefits of power management, the manufacturer will include with each computer, one of the

437	following:

438

439	• Information on ENERGY STAR and the benefits of power management in either a hard copy or

440	electronic copy of the user manual. This information should be near the front of the user guide.

441	• A package or box insert on ENERGY STAR and the benefits of power management.

442

443	Either option must include the following information:

444

445	• Notice that the computer has been shipped enabled for power management and what the time

446	settings are
How to properly wake the computer from Sleep mode
Energy saving benefits
Money saving benefits
Environmental benefits

Some information on ENERGY STAR and a link to www.enerqvstar.gov

447

448

449

450

451

452

453

454	In addition, the manufacturer will have similar information with a link to

455	www.enerqvstar.gov/powermanaqement on the company Web site, readily accessible from computer

456	product pages, product specifications, and related content pages.

457

458	At the manufacturer's request, EPA will supply suggested facts and figures related to the above

459	criteria, template elements, or a complete template suitable for use in user guides or box inserts.

460

461	EPA's goal is to achieve a 40% enabling rate nationally by 2010; 60% by 2012; and > 80% by 2014.

462	EPA recognizes the importance of documenting enabling rates and encourages industry to develop a

463	collective strategy for securing and funding this research, and sharing findings with EPA and the

464	public.

465

466

467	(B) Tier 2 Requirements - Effective January 1. 2009

468

469	(1a) Tier 2 Capability Benchmark: All computers will be required to meet the following minimum

470	performance per unit energy metric.

471

472	Performance Benchmarking Software and Associated Levels: TBD

473	- OR -

474

475	(1 b) Provisional Tier 2 Idle State Requirements: If an energy efficiency performance or capability

476	benchmark, and associated performance levels, are not ready to go into effect by January 1, 2009, a

477	provisional Tier 2 specification will automatically go into effect and will remain in effect until such a

478	benchmark is established. This provisional Tier 2 will include revised Idle state levels for all computer

479	types (those included in Tier 1 as well as others as appropriate [e.g., thin clients]) with the intention of

480	capturing the top 25% energy performers.

481

482	Additional topics, including the following, will also be re-examined under a provisional Tier 2:

483

484	• Idle levels for notebooks and integrated computers that incorporate the energy use of the displays.

485

486	• Quantitative distinctions between desktop categories (e.g., Mb of video memory, number of

487	processor cores, Mb of system memory) to make sure these distinctions remain current.

488

489	• Sleep levels for game consoles and desktop-derived servers.

ENERGY STAR Program Requirements for Computers: Draft 2 Version 4.0	14


-------
490

491	• Allowances for Out-Of-Bound (OOB) client management tools in Sleep and Standby that may aid

492	in the adoption of computer power management.

493

494	In the case of the implementation of a provisional Tier 2, EPA will re-examine these new topics and

495	finalize new levels at least six months prior to the effective date for Tier 2.

496

Note: EPA will be sharing with stakeholders additional information on the planned process and timing for
the development of a Tier 2 Capability Benchmark in the coming weeks.

497

498	(2) Power Management Requirements: In addition to the requirements provided under Tier 1,

499	above, ENERGY STAR qualified computers must retain full network connectivity while in Sleep mode,

500	according to a platform-independent industry standard. All computers shall reduce their network link

501	speeds during times of low data traffic levels in accordance with any industry standards that provides

502	for quick transitions among link rates.

Note: Proposed levels for the provisional Tier 2 Idle requirements have been removed so that EPA can
review performance data that is representative of products found in the marketplace prior to Tier 2 taking
effect. It is EPA's intention to achieve significant power savings from Tier 2, thus levels established in a
provisional Tier 2 will represent the top 25% of computers across all product types.

A dynamic link scaling requirement has been added because the great majority of network links are used
at low percentages of their data transmission capability. There is discussion in the Ethernet community
about developing the ability to seamlessly switch link rates quickly to assure no impairment of user
experience. With such capabilities in place, reduced link rates are expected to be heavily used on Tier 2
computers, and have the potential for significant savings.

503

504	C) Voluntary Requirements

505

506	User Interface: Although not mandatory, manufacturers are strongly recommended to design

507	products in accordance with the Power Control User Interface Standard — IEEE 1621 (formally known

508	as "Standard for User Interface Elements in Power Control of Electronic Devices Employed in

509	Office/Consumer Environments"). Compliance with IEEE 1621 will make power controls more

510	consistent and intuitive across all electronic devices. For more information on the standard see

511	http://eetd.LBL.gov/Controls.

512

513

514	4) Test Procedures: Manufacturers are required to perform tests and self-certify those models that

515	meet the ENERGY STAR guidelines.

516

517	-In performing these tests, partner agrees to use the test procedures provided in Table 2, below.

518

519	¦ The test results must be reported to EPA using the Computer Version 4.0 Qualifying Product

520	Information (QPI) Form.

521

522	Models Capable of Operating at Multiple Voltage/Frequency Combinations: Manufacturers shall

523	test their products based on the market(s) in which the models will be sold and promoted as ENERGY

524	STAR qualified. For products that are sold as ENERGY STAR in multiple international markets and,

525	therefore, rated at multiple input voltages, the manufacturer must test at and report the required power

526	consumption or efficiency values at all relevant voltage/frequency combinations. For example, a

527	manufacturer that is shipping the same model to the United States and Europe must measure, meet

528	the specification, and report test values at both 115 Volts/60 Hz and 230 Volts/50 Hz in order to qualify

529	the model as ENERGY STAR in both markets. If a model qualifies as ENERGY STAR at only one

ENERGY STAR Program Requirements for Computers: Draft 2 Version 4.0	15


-------
530	voltage/frequency combination (e.g., 115 Volts/60 Hz), then it may only be qualified and promoted as

531	ENERGY STAR in those regions that support the tested voltage/frequency combination (e.g., North

532	America and Taiwan).

Note: In response to a number of industry requests that the test procedures be streamlined, EPA has
consolidated the Standby, Sleep, and Idle test procedures into one document. It is EPA's hope that
this will facilitate and expedite the ENERGY STAR testing process. Stakeholders are encouraged to
review this new test procedure in Appendix A of this specification.

535

536	5) Effective Date: The date that manufacturers may begin to qualify products as ENERGY STAR,

537	under this Version 4.0 specification, will be defined as the effective date of the agreement. Any

538	previously executed agreement on the subject of ENERGY STAR qualified computers shall be

539	terminated effective June 30, 2007.

540

541	1. Qualifying Products Under Tier 1 of the Version 4.0 Specification: The first phase of this

542	specification is proposed to commence on July 1, 2007. All products, including models originally

543	qualified under Version 3.0, with a date of manufacture on or after July 1, 2007, must meet the

544	new (Version 4.0) requirements in order to qualify for ENERGY STAR. The date of manufacture

545	is specific to each unit and is the date (e.g., month and year) of which a unit is considered to be

546	completely assembled.

547

548	2. Qualifying Products Under Tier 2 of the Version 4.0 Specification: The second phase of this

549	specification, Tier 2, is proposed to commence on January 1, 2009. All products, including

550	models originally qualified under Tier 1, with a date of manufacture on or after January 1, 2009,

551	must meet the Tier 2 requirements in order to qualify for ENERGY STAR.

552

553	3. Elimination of Grandfathering: EPA will not allow grandfathering under this Version 4.0 ENERGY

554	STAR specification. ENERGY STAR qualification under previous Versions is not

555	automatically granted for the life of the product model. Therefore, any product sold,

556	marketed, or identified by the manufacturing partner as ENERGY STAR must meet the current

557	specification in effect at the time of manufacture of the product.

558

ENERGY STAR Program Requirements for Computers: Draft 2 Version 4.0	16


-------
Note: On February 24, 2006, EPA announced a new Tier I effective date of July 1, 2007. This
extension is intended to allow manufacturers time to meet the proposed Tier 1 80% internal power
supply requirement. Based on discussions with both computer manufacturers and suppliers of efficient
power supplies, EPA feels confident that an 80% efficiency requirement is achievable on or before July
1, 2007. Additionally, EPA appreciates that numerous manufacturers seek finality on this matter for
product planning purposes. Thus, this draft specification is intended to forecast clearly that EPA intends
to include this requirement, as stated in Draft 2, in the Final Computer Specification. In conjunction with
the new Tier 1 effective date, EPA is now proposing a new Tier 2 effective date of January 1, 2009.

6) Future Specification Revisions: EPA reserves the right to revise the specification should
technological and/or market changes affect its usefulness to consumers or industry or its impact on
the environment. In keeping with current policy, revisions to the specification will be discussed with
stakeholders. In the event of a specification revision, please note that ENERGY STAR qualification is
not automatically granted for the life of a product model. To qualify as ENERGY STAR, a product
model must meet the ENERGY STAR specification in effect on the model's date of manufacture.


-------
566	APPENDIX A

567	ENERGY STAR Test Procedure for Determining the

568	Power Use of Computers in Standby, Sleep, and Idle

569

570	The following protocol should be followed when measuring power consumption levels of computers for

571	compliance with the Standby, Sleep, and Idle levels provided in the ENERGY STAR Version 4.0

572	Computer Specification. Partners must measure a representative sample of the configuration that it ships

573	to the customer. However, the Partner does not need to consider power consumption changes that may

574	result from component additions made by the computer user after sale of product. This procedure is

575	intended to be followed in order and the mode being tested is labeled where appropriate.

Note: In response to stakeholder comments, EPA has created a consolidated test method for this draft
specification. The creation of this consolidated test method involved the following major changes:

•	Appendices A and B were combined into a single Test Procedure appendix to include a unified test
method for all three power modes.

•	The technical details related to selecting a power meter have been removed. The Approved meter
requirements remain unchanged and have mostly been harmonized with 62301 Ed 1.0:
Measurement of Standby power.

•	Power mode definitions removed in favor of those used in the specification.

•	Test procedure now clearly allows for testing at multiple voltages based on intended market.

Stakeholders are encouraged to provide feedback on this proposed test method.

576

577	I. Definitions

578

579	Unless otherwise specified, all terms used in this document are consistent with the definitions

580	contained in the Version 4.0 ENERGY STAR Eligibility Criteria for Computers.

581

582	UUT

583	UUT is an acronym for "unit under test," which in this case refers to the computer being tested.

584

585	UPS

586	UPS is an acronym for "Uninterruptible Power System," which refers to a combination of converters,

587	switches and energy storage means, for example batteries, constituting a power system for

588	maintaining continuity of load power in case of input power failure.

589

590

591 II. Testing Requirements

592

593	Approved Meter

594	Approved meters will include the following attributes1:

595

596	• Power resolution of 1 mW or better;

597	• An available current crest factor of 3 (or more) at its rated range value;

598	• Minimum current range of 10mA (or less).

599

600	EPA also suggests the following attributes in addition to those above:

601

602	• Frequency response of at least 3 kHz;

603	• Calibrated with a standard that is traceable to the U.S. National Bureau of Standards (NBS).

604

ENERGY STAR Program Requirements for Computers: Draft 2 Version 4.0	18


-------
605	It is also desirable for measurement instruments to be able to average power accurately over any user

606	selected time interval (this is usually done with an internal math's calculation dividing accumulated

607	energy by time within the meter, which is the most accurate approach). As an alternative, the

608	measurement instrument would have to be capable of integrating energy over any user selected time

609	interval with an energy resolution of less than or equal to 0.1 mWh and integrating time displayed with

610	a resolution of 1 second or less.

611

612	Accuracy

613	Measurements of power of 0.5 W or greater shall be made with an uncertainty of less than or equal to

614	2 % at the 95 % confidence level. Measurements of power of less than 0.5 W shall be made with an

615	uncertainty of less than or equal to 0.01 W at the 95 % confidence level. The power measurement

616	instrument shall have a resolution of:

617

618	• 0.01 W or better for power measurements of 10 W or less;

619	• 0.1 W or better for power measurements of greater than 10 W up to 100 W;

620	• 1 W or better for power measurements of greater than 100 W.

621

622	All power figures should be in watts and rounded to the second decimal place. For loads greater than

623	or equal to 10 W, three significant figures shall be reported.

624

625	Test Conditions

626	• Line Impedance: < 0.25 ohm

627	• Total Harmonic Distortion: < 5%

628	• Ambiant Temperature: 25 degrees C +/- 3 degrees C

629	• For products to be qualified in markets using 100V / 120V input:

630	- Input AC Voltage: 115 VAC RMS +/- 5V RMS

631	- Input AC Frequency: 60 Hz +/- 3 Hz

632	• For products to be qualified in markets using 230V input:

633	- Input AC Voltage: 230 VAC RMS +/- 5V RMS

634	- Input AC Frequency: 50 Hz +/- 3 Hz

635

636	Test Configuration

637	Power consumption of a computer shall be measured and tested from an AC source to the UUT.

638

639	The UUT must be connected to an Ethernet network switch capable of the UUT's maximum network

640	speed. The network connection must be live during all tests.

641

642

643	III. Test Procedure

644	Measurement of ac power consumption of a computer should be conducted as follows:

645

646	UUT Preparation

647	1. Record the manufacturer and model name of the UUT.

648	2. Ensure that the UUT is connected to a live Ethernet (IEEE 802.3) network switch as specified in

649	Section II., "Test Configuration," above, and that the connection is live. The computer must

650	maintain this live connection to the switch for the duration of testing, disregarding brief lapses

651	when transitioning between link speeds

652	3. Connect an approved meter capable of measuring true power to an ac line voltage source set to

653	the appropriate voltage/frequency combination for the test.

654	4. Plug the UUT into the measurement power outlet on the meter. No power strips or UPS units

655	should be connected between the meter and the UUT. For a valid test to take place the meter

656	should remain in place until all Standby, Sleep, and Idle power data is recorded.

657	5. Record the ac voltage.

658	6. Boot computer and wait until the operating system has fully loaded.

the following requirements for all tests:

a.	Desktop systems (including workstations and desktop-derived servers) shipped without
accessories should be configured with a standard mouse, keyboard and external monitor.

b.	Notebooks and tablets should include all accessories shipped with the system, and need
not include a separate keyboard or mouse when equipped with an integrated pointing
device or digitizer.

c.	Notebooks and tablets should have the batteries removed for all tests.

10.	For computers with integrated monitors (notebooks, tablets and integrated systems), use the
power management settings to set the monitor to power down after 1 minute (adjust no other
power management settings).

11.	Shut down the computer.

Standby (Off Mode) Testing

12.	With the UUT shut down and in Standby, set the meter to begin accumulating true power values at
an interval of 1 reading per second. Accumulate power values for 5 additional minutes and record
the average (arithmetic mean) value observed during that 5 minute period.4 Record the Standby
power.

4	Laboratory-grade, full-function meters can integrate values over time and report the average value automatically.
Other meters would require the user to capture a series of changing values every 5 seconds for a five minute period
and then compute the average manually.

684	Idle Mode Testing

685	13. Switch on the computer and begin recording elapsed time. After the operating system has fully

686	loaded, close any windows that may be open. Exactly 5 minutes after the computer was switched

687	on, set meter to begin accumulating true power values at an interval of 1 reading per second.

688	Accumulate power values for 5 additional minutes and record the average (arithmetic mean) value

689	observed during that 5 minute period. The data-recording period should not be more than 5

690	minutes so as to prevent potential data collection after additional power management settings

691	have taken effect.

692

693	Sleep Mode Testing

694	14. After completing the Idle measurements, place the computer in Sleep mode. Reset the meter (if

695	necessary) and begin accumulating true power values at an interval of 1 reading per second.

696	Accumulate power values for 5 additional minutes and record the average (arithmetic mean) value

697	observed during that 5 minute period. Record the Sleep power.

698	15. If testing both WOL enabled and WOL disabled for Sleep, reboot the computer and change the

699	WOL from Sleep setting through the operating system settings or by other means. Place the

700	computer back in Sleep mode and repeat step 16, recording Standby power for this alternate

701	configuration.

702

703	Reporting Test Results

704	16. The test results must be reported to EPA using the Computer Version 4.0 Qualifying Product

705	Information (QPI) Form, taking care to ensure that all required information has been included.

706

707

708	IV. Continuing Verification

709

710	This testing procedure describes the method by which a single unit may be tested for compliance. An

711	ongoing testing process is highly recommended to ensure that products from different production runs

712	are in compliance with ENERGY STAR.
