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: 77 1. On the top/front of the product. Labeling on the top/front of product may be permanent or 78 temporary. All temporary labeling must be affixed to the top/front of product with an adhesive or 79 cling-type application; 80 Electronic Labeling Option: Manufacturers have the option of using an alternative electronic 81 labeling approach in place of this product labeling requirement, as long it meets the following 82 requirements: 83 84 85 86 87 88 89 90 91 92 EPA will consider alternative proposals for electronic labeling on a case-by-case basis. 93 94 2. In product literature (i.e., user manuals, spec sheets, etc.); 95 3. On product packaging for products sold at retail; and ENERGY STAR Program Requirements for Computers: Draft 3 Version 4.0 2 The ENERGY STAR mark in cyan, black, or white (as described in The ENERGY STAR Identity Guidelines" 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 the screen by area, may not be smaller than 76 pixels x 78 pixels, and must be legible. ------- 96 97 98 99 100 101 102 4. On the manufacturer's Internet site where information about ENERGY STAR qualified models is displayed: - If information concerning ENERGY STAR is provided on the Partner Web site, as specified by the ENERGY STAR Web Linking Policy (this document can be found in the Partner Resources section on the ENERGY STAR Web site at www.enerqvstar.gov). EPA may provide links where appropriate to the Partner Web site; 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 Note: The packaging requirement is meant to distinguish qualified products to consumers in retail settings. Thus, the labeling requirements have been changed to allow manufacturers preparing products not destined for a retail setting to choose whether they wish to label the packaging of these products. Clarifying language regarding the physical labeling of products has also been added. • provide to EPA, on an annual basis, an updated list of ENERGY STAR qualified computer models. Once the Partner submits its first list of ENERGY STAR qualified computer models, the Partner will be listed as an ENERGY STAR Partner. Partner must provide annual updates in order to remain on the list of participating product manufacturers; • provide to EPA, on an annual basis, unit shipment data or other market indicators to assist in determining the market penetration of ENERGY STAR. Specifically, Partner must submit the total number of ENERGY STAR qualified computers shipped (in units by model) or an equivalent measurement as agreed to in advance by EPA and Partner. Partner is also encouraged to provide ENERGY STAR qualified unit shipment data segmented by meaningful product characteristics (e.g., capacity, size, speed, or other as relevant), total unit shipments for each model in its product line, and percent of total unit shipments that qualify as ENERGY STAR. The data for each calendar year should be submitted to EPA, preferably in electronic format, no later than the following March and may be provided directly from the Partner or through a third party. The data will be used by EPA only for program evaluation purposes and will be closely controlled. Any information used will be masked by EPA so as to protect the confidentiality of the Partner; • notify EPA of a change in the designated responsible party or contacts for computers within 30 days. Performance for Special Distinction In order to receive additional recognition and/or support from EPA for its efforts within the Partnership, the ENERGY STAR Partner may consider the following voluntary measures and should keep EPA informed on the progress of these efforts: • consider energy efficiency improvements in company facilities and pursue the ENERGY STAR mark for buildings; • purchase ENERGY STAR qualified products. Revise the company purchasing or procurement specifications to include ENERGY STAR. Provide procurement officials' contact information to EPA for periodic updates and coordination. Circulate general ENERGY STAR qualified product information to employees for use when purchasing products for their homes; • ensure the power management feature is enabled on all ENERGY STAR qualified monitors and computers in use in company facilities, particularly upon installation and after service is performed; • provide general information about the ENERGY STAR program to employees whose jobs are relevant to the development, marketing, sales, and service of current ENERGY STAR qualified product models; • provide a simple plan to EPA outlining specific measures Partner plans to undertake beyond the ENERGY STAR Program Requirements for Computers: Draft 3 Version 4.0 ------- 146 program requirements listed above. By doing so, EPA may be able to coordinate, communicate, 147 and/or promote Partner's activities, provide an EPA representative, or include news about the event in 148 the ENERGY STAR newsletter, on the ENERGY STAR Web pages, etc. The plan may be as simple 149 as providing a list of planned activities or planned milestones that Partner would like EPA to be aware 150 of. For example, activities may include: (1) increase the availability of ENERGY STAR qualified 151 products by converting the entire product line within two years to meet ENERGY STAR guidelines; (2) 152 demonstrate the economic and environmental benefits of energy efficiency through special in-store 153 displays twice a year; (3) provide information to users (via the Web site and user's manual) about 154 energy-saving features and operating characteristics of ENERGY STAR qualified products: and (4) 155 build awareness of the ENERGY STAR Partnership and brand identity by collaborating with EPA on 156 one print advertorial and one live press event; 157 158 • provide quarterly, written updates to EPA as to the efforts undertaken by Partner to increase 159 availability of ENERGY STAR qualified products, and to promote awareness of ENERGY STAR and 160 its message. ENERGY STAR Program Requirements for Computers: Draft 3 Version 4.0 ------- ENERGY STAR Program Requirements for Computers Eligibility Criteria DRAFT 3 [££_ 167 168 Below is the DRAFT 3 Version 4.0 product specification for ENERGY STAR qualified computers. A 169 product must meet all of the identified criteria to earn the ENERGY STAR. 170 171 1) Definitions: Below are the definitions of the relevant terms in this document. 172 173 A. Computer: A device which performs logical operations and processes data. Computers are 174 composed of, at a minimum: (1) a central processing unit (CPU) to perform operations; (2) user 175 input devices such as a keyboard, mouse, digitizer or game controller; and (3) a display screen to 176 output information. For the purposes of this specification, computers include both stationary and 177 portable units, including desktop computers, gaming consoles, integrated computers, notebook 178 computers, tablet PCs, desktop-derived servers and workstations. 179 180 Components 181 182 B. Display: A commercially-available, electronic product with a display screen and its associated 183 electronics encased in a single housing, or within the computer housing (e.g., notebook or 184 integrated computer), that is capable of displaying output information from a computer via one or 185 more inputs, such as a VGA, DVI, and/or IEEE 1394. Examples of display technologies are the 186 cathode-ray tube (CRT) and liquid crystal display (LCD). 187 188 C. External Power Supply: A component contained in a separate physical enclosure external to the 189 computer casing and designed to convert line voltage ac input from the mains to lower dc 190 voltage(s) for the purpose of powering the computer. An external power supply must connect to 191 the computer via a removable or hard-wired male/female electrical connection, cable, cord or 192 other wiring and have a nameplate output power less than or equal to 250 watts. 193 194 D. Internal Power Supply: A component internal to the computer casing and designed to convert ac 195 voltage from the mains to dc voltage(s) for the purpose of powering the computer components. 196 For the purposes of this specification, an internal power supply must be contained within the 197 computer casing but be separate from the main computer board. The power supply must connect 198 to the mains through a single cable with no intermediate circuitry between the power supply and 199 the mains power. In addition, all power connections from the power supply to the computer 200 components must be internal to the computer casing (i.e., no external cables running from the 201 power supply to the computer or individual components). Internal dc to dc converters used to 202 convert a single dc voltage from an external power supply into multiple voltages for use by the 203 computer are not considered internal power supplies. 204 205 Computer Types 206 207 E. Desktop Computer: A computer where the main unit is intended to be located in a permanent 208 location, often on a desk or on the floor. Desktops are not designed for portability and utilize an 209 external monitor, keyboard, and mouse. Desktops are designed for a broad range of home and 210 office applications including, email, web browsing, word processing, standard graphics 211 applications, gaming, etc. 212 213 ENERGY STAR Program Requirements for Computers: Draft 3 Version 4.0 ------- 214 F. Desktop-Derived Server: A desktop-derived server is a computer that typically uses desktop 215 components in a tower form factor, but is designed explicitly to be a host for other computers or 216 applications. For the purposes of this specification, a computer must be marketed as a server and 217 have the following characteristics to be considered a desktop-derived server: 218 219 • Designed and placed on the market as a Class B product per EuroNorm EN55022:1998 under 220 the EMC Directive 89/336/EEC and has no more than single processor capability (1 socket on 221 board); 222 223 • Designed in a pedestal, tower, or other form factor similar to those of desktop computers such 224 that all data processing, storage, and network interfacing is contained within one box/product; 225 226 • Designed to operate in a high-reliability, high-availability application environment where the 227 computer must be operational 24 hours/day and 7 days/week, and unscheduled downtime is 228 extremely low (on the order of hours/year); 229 230 • Capable of operating in a simultaneous multi-user environment serving several users through 231 networked client units; and 232 233 • Shipped with an industry accepted operating system for standard server applications (e.g., 234 Windows NT, Windows 2003 Server, Mac OS X Server, OS/400, OS/390, Linux, Unix and 235 Solaris). 236 237 Desktop-derived servers are designed to perform functions such as processing information for 238 other systems, providing network infrastructure services (e.g., archiving), data hosting and running 239 webservers. 240 241 This specification does not cover mid-range or large servers, defined for purposes of this 242 specification as: 243 244 • Designed and placed on the market as a Class A product per EuroNorm EN55022:1998 under 245 the EMC Directive 89/336/EEC and designed and capable of having a single or dual 246 processor capability (1 or greater sockets on board); and 247 248 • Designed and placed on the market as a Class B product per EuroNorm EN55022:1998 under 249 the EMC Directive 89/336/EEC and designed and capable of having a minimum dual 250 processor capability (2 sockets on board). 251 252 G. Game Consoles: Stand alone computers whose primary use is to play video games. For the 253 purposes of this specification, game consoles must use a hardware architecture based on typical 254 computer components (e.g., processors, system memory, video architecture, optical and/or hard 255 drives, etc.). The primary input for game consoles are special hand held controllers rather than 256 the mouse and keyboard used by conventional computer types. Game consoles are also 257 equipped with audio visual outputs for use with televisions as the primary display, rather than an 258 external monitor or integrated display. These devices do not typically use a conventional 259 operating system, but often perform a variety of multimedia functions such as: DVD/CD playback, 260 digital picture viewing, and digital music playback. 261 262 H. Integrated Computer: A desktop system in which the computer and display function as a single 263 unit which receives its ac power through a single cable. Integrated computers come in one of two 264 possible forms: (1) a system where the display and computer are physically combined into a 265 single unit; or (2) a system packaged as a single system where the display is separate but is 266 connected to the main chassis by a dc power cord and both the computer and display are 267 powered from a single power supply. As a subset of desktop computers, integrated computers 268 are typically designed to provide similar functionality as desktop systems. ENERGY STAR Program Requirements for Computers: Draft 3 Version 4.0 6 ------- 269 Note: Some stakeholders expressed concern about how to qualify computers packaged with dedicated monitors that connect to the main computer with a dc power cord. After researching this issue, EPA modified the definition of integrated computers to include computers with displays powered by a dc power cord off of the main unit's power supply. EPA believes that these products should fit the definition of integrated computers even though they do not share a single housing because these products share a single power supply and are therefore, technically equivalent to integrated computers though in a slightly different form. 271 272 I. Notebook and Tablet Computers: A computer designed specifically for portability and to be 273 operated for extended periods of time without a direct connection to an ac power source. 274 Notebooks and tablets must utilize an integrated monitor and be capable of operation off an 275 integrated battery or other portable power source. In addition, most notebooks and tablets use an 276 external power supply and have an integrated keyboard and pointing device, though tablets use 277 touch sensitive screens. Notebook and tablet computers are typically designed to provide similar 278 functionality to desktops except within a portable device. For the purposes of this specification, 279 docking stations are considered accessories and therefore, the performance levels associated 280 with notebooks presented in Table 1 of section 3, below, do not include them. 281 282 J. Workstation: For the purposes of this specification, to qualify as a workstation, a computer must: 283 • Be marketed as a workstation; 284 • Have a mean time between failures (MTBF) of at least 15,000 hours based on Bellcore TR- 285 NWT-000332, issue 6, 12/97; and 286 • Support error-correcting code (ECC) and/or buffered memory. 287 288 In addition, a workstation must meet three of the following six optional characteristics: 289 • Have supplemental power support for high end graphics (i.e., PCI-E 6-pin 12V supplemental 290 power feed); 291 • System is wired for 4x or 8x PCI-E on motherboard in addition to graphics slot(s) and/or PCI-X 292 support; 293 • Does not support Uniform Memory Access (UMA) graphics; 294 • Includes 5 or more PCI, PCIe, PCI-X slots; 295 • Capable of multi-processor support for two or more processors (must support physically 296 separate processor packages/sockets, i.e., not met with support for a single multi core 297 processor); and/or 298 • Be qualified by at least 2 Independent Software Vendor (ISV) product certifications; these 299 certifications can be in process, but must be completed within 3 months of qualification. 300 ENERGY STAR Program Requirements for Computers: Draft 3 Version 4.0 ------- 301 302 303 304 305 306 307 308 309 310 311 312 313 314 315 316 317 318 319 320 321 322 323 324 325 326 327 328 329 330 331 332 333 334 335 336 337 338 339 Notes: Definitions for the terms included in the workstation definition will be included in the Final Draft. Some stakeholders felt that EPA's proposed workstation definition relied too heavily on the specific configuration of the system, and that a simpler definition could be created that accurately differentiates a workstation based on its inherent capabilities. EPA and industry have worked through several iterations to develop this new definition which EPA believes meets these goals of accuracy and simplicity. This definition was released to stakeholders in the 6/12/06 Computer Specification Progress Update, and the Draft 3 version reflects changes based on comments received in response to that release. EPA feels that this definition is close to the definition that will be used in the final specification. However, EPA would like feedback on a few points raised just prior to the release of this draft. These points are as follows: (1) Is 5 PCI/ PCIe/PCI-X slots adequate to differentiate workstations from desktops; (2) Would substituting greater than four cores for symmetric multiprocessing (SMP) support further EPA's goal of distinguishing workstations from desktops; and (3) EPA intends for all PCIe slots to be wired for high bandwidth - are there compatibility issues associated with this line item, and would aggregated I/O simplify this optional requirement? EPA will evaluate all feedback received in the development of the Final Draft. 2) Operational Modes K. Idle State: For purposes of testing and qualifying computers under this specification, this is the state in which the operating system and other software have completed loading, the machine is not asleep, and activity is limited to those basic applications that the system starts by default. L. Sleep Mode: A low power state that the computer is capable of entering automatically after a period of inactivity or by manual selection. A computer with sleep capability can quickly "wake" in response to network connections or user interface devices. For the purposes of this specification, Sleep mode correlates to ACPI System Level S3 (suspend to RAM) state, where applicable. M. Standby Level (Off Mode): The power consumption level in the lowest power mode which cannot be switched off (influenced) by the user and that may persist for an indefinite time when the appliance is connected to the main electricity supply and used in accordance with the manufacturer's instructions. For purposes of this specification, Standby correlates to ACPI System Level S4 or S5 states, where applicable. Networking and Power Management N. Network Interface: The components (hardware and software) whose primary function is to make the computer capable of communicating over one or more network technologies. For purposes of testing to this specification, Network Interface refers to the IEEE 802.3 wired Ethernet interface. O. Wake Event: A user, programmed, or external event or stimulus that causes the computer to transition from Sleep or Standby to active mode of operation. Examples of wake events include, but are not limited to: movement of the mouse, keyboard activity, or a button press on the chassis, and in the case of external events, stimulus conveyed via a remote control, network, modem, etc. P. Wake-On LAN (WOL): Functionality which allows a computer to wake from Sleep or Standby when directed by a network request. Qualifying Products: Computers must meet the computer definition as well as one of the product type definitions provided in Section 1, above, to qualify as ENERGY STAR. Please note that EPA will explore additional computer types, such as thin clients, for potential Tier 2 requirements. The following table provides a list of the types of computers that are (and are not) eligible for ENERGY STAR. ENERGY STAR Program Requirements for Computers: Draft 3 Version 4.0 ------- 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 340 341 3) Energy Efficiency and Power Management Criteria: Computers must meet the 342 requirements below to qualify as ENERGY STAR. Proposed effective dates for Tier 1 and Tier 2 are 343 covered in Section 5 of this specification. 344 345 A) Tier 1 Requirements - Effective July 1. 2007 346 347 (1) Power Supply Efficiency Requirements 348 349 Computers Using an Internal Power Supply: 80% minimum efficiency at 20%, 50%, and 100% of 350 rated output and Power Factor > 0.9 at 100% of rated output. 351 352 Computers Using an External Power Supply: Must be ENERGY STAR qualified or meet the no- 353 load and active mode efficiency levels provided in the ENERGY STAR Program Requirements for 354 Single Voltage Ac-Ac and Ac-Dc External Power Supplies. The ENERGY STAR specification and 355 qualified product list can be found at www.enenavstar.gov/powersupplies. Note: This performance 356 requirement also applies to multiple voltage output external power supplies as tested in accordance to 357 the Internal Power Supply test method referenced in Section 4, below. 358 359 (2) Operational Mode Efficiency Requirements 360 361 Desktop Differentiation: 362 For the purposes of determining Idle state levels, desktops and integrated computers must qualify 363 under Categories A, B, or C as defined below: 364 365 Category A: All desktop computers that do not meet the definition of either Category B or 366 Category C below are considered under Category A for ENERGY STAR qualification. 367 368 Category B: To qualify under Category B desktops must have: 369 • Multi-core processor(s) or greater than 1 discrete processor; and 370 • Minimum of 1 gigabyte of system memory. 371 372 Category C: To qualify under Category C desktops must have: 373 • Multi-core processor(s) or greater than 1 discrete processor; and 374 • A GPU with greater than 128 megabytes of dedicated, non-shared memory. 375 376 In addition to the requirements above, models qualifying under Category C must be configured 377 with a minimum of 2 of the following three characteristics: 378 • Minimum of 2 gigabytes of system memory; 379 • TV tuner and/or video capture capability with high definition support; and/or 380 • Minimum of 2 hard disk drives. ENERGY STAR Program Requirements for Computers: Draft 3 Version 4.0 9 ------- 381 382 383 384 385 386 387 388 389 390 391 392 393 394 395 396 397 398 399 Note: After extensive discussions with stakeholders, the category system for desktops has been revised to allow for greater differentiation between desktops for the purposes of Idle allowances. This change was made to better reflect the range of capabilities of desktops currently in the marketplace. However, if data provided in August is not robust enough for EPA to set levels for each of the three categories, EPA may return to its initial two category proposal. Notebook Differentiation: A couple of stakeholders submitted comments and data indicating the need to differentiate notebooks based on performance, similar to what EPA did with desktops. This data shows that some notebooks with advanced graphics capability use additional energy in Idle. EPA continues to believe that notebooks with advanced graphics occupy a relatively small niche market. EPA also believes that the advanced power management available for these products makes a flat line Idle requirement achievable for all notebooks, an approach supported by EPA's initial data collection efforts. EPA may consider a differentiation for notebooks based solely on discrete graphics if the data provided in August supports this conclusion. Absent data from industry, EPA will continue to move forward with a single Idle level for notebooks. Workstation Levels: Workstation levels will be determined using a simplified Typical Electricity Consumption (TEC) approach to allow manufacturers energy trade offs between different operating modes, based on a given weighting factor for each mode. The final level will be based on the TEC power level (Ptec) which will be determined by the following formula: Ptfc= A * P0ff + B * P; Sleep + c*p Idle where, P0ff is the power measured in Off, PSieeP is the power measured in Sleep and in P|die is the power measured in Idle (Note - A, B and C represent the weighting factor for each operational mode and are TBD based on industry submitted data). This simplified TEC approach will be used in combination with a scalable classifier to scale the power allowance according to the capability of the system. Workstation Scalable Classifier: TBD Note: EPA has included the simplified TEC approach as discussed with stakeholders at the May stakeholder meeting. This approach has been added to give manufacturers the ability to use alternative approaches to energy savings in workstations, since workstations often use advanced technology which warrants special consideration. Though EPA has not gone in this direction for desktops and notebooks, EPA is willing to try this approach for workstations because of their unique characteristics and relatively small market share. EPA also agreed in concept to a scalable classifier for workstations, and has been working with stakeholders to gather the necessary information and data to determine the effectiveness of such an approach. EPA appreciates all data submitted to support this effort, but due to a low volume of data and gaps in the data initially submitted, EPA has not been able to properly assess if a scalable classifier based on percentage of maximum power is achievable. In email communications dated June 23 and 26, 2006, EPA provided feedback on what further data is needed to continue to pursue this approach. In a revised timeline shared on June 23, 2006 EPA asked that all appropriate data be submitted by July 10, 2006. After the data is collected, EPA will conduct a call on July 13, 2006 to discuss the proposed approach followed by an announcement of the final approach on July 17, 2006. Although EPA remains committed to these approaches for workstations, without an adequate data set EPA will return to the Draft 2 approach. ENERGY STAR Program Requirements for Computers: Draft 3 Version 4.0 10 ------- 400 401 402 403 404 405 406 407 408 Power Level Requirements: The following tables indicate the required power allowances for the Tier 1 specification. Table 1 gives the baseline requirements, while Table 2 gives additional power allowances for WOL and increased system memory. For those products that meet the WOL and memory requirements, a model must meet the energy level provided in Table 1 summed with the appropriate allowances from Table 2. Note: Products whose Sleep levels meet the Standby power requirements do not need to have a distinct Off mode, and may qualify for this specification using only Sleep mode. Table 1: Tier 1 Energy Efficiency Requirements Product Type Tier 1 Requirements Desktops, Integrated Computers and Gaming Consoles Standby (Off Mode): < TBD W Sleep Mode: < TBD W Idle State: Category A: < TBD W Category B: < TBD W Category C: < TBD W Desktop-Derived Servers Standby (Off Mode): < TBD W Sleep Mode: N/A Idle State: < TBD W Notebooks Standby (Off Mode): < TBD W Sleep Mode: < TBD W Idle State: < TBD W Workstations TEC Power (PTEC): ^ TBD W 409 Table 2: Tier 1 Ca abilit Adders for Slee and Standb 410 411 WOL TBD watts for Sleep and/or Standby System Memory TBD watts for Sleep per memory module greater than two ENERGY STAR Program Requirements for Computers: Draft 3 Version 4.0 11 ------- Note: There was industry concern that the data used to inform the proposed performance levels reflected in Draft 2 of the Computer Specification were not representative of new technologies and platforms that would be in production when the specification is finalized. According to some manufacturers, these new technologies could require additional energy budgets and would be more representative of products available when the specification takes effect on July 1, 2007. In response to this concern, EPA is allowing manufacturers additional time to test and report all models available when this specification is finalized. Therefore, all levels in this Draft 3 specification are denoted as "TBD" and will be based on data submitted by industry in August. EPA is taking this approach to ensure that the levels included in this specification are representative of the products that will actually be available when the specification is finalized in September, 2006. The attached final data sheet must be completed and returned to EPA no later than August 4, 2006, to have data considered in this final analysis. It is important that the data points submitted are reflective of both varied configurations of the same model as well as a range of different models, so that EPA has a solid data set on which to base the specification lines. Absent a sufficiently robust and varied data set, EPA will use data collected to date to set all levels. Integrated Computers: Some stakeholders commented that integrated computers should be allowed additional power over desktops. EPA believes there is no technical justification for why these systems need additional power, most notably because they only have losses through a single power supply for low power modes. Furthermore, the power used by the monitor is not accounted for under the Idle test procedure since the monitor remains off during testing. Lastly, the data collected by EPA to date supports the conclusion that additional power allowances are not needed for integrated computers. Thus, EPA plans to keep these requirements unless data submitted in August justifies a higher power allowance. Game Consoles: Game consoles will now be treated as desktops for the purposes of this specification. To earn the ENERGY STAR mark, game consoles will now have to meet all the same definitions and levels as desktops, which will include the necessity of a low power sleep requirement. This change was made because EPA has received very little feedback on game console systems, and with the new differentiation approach for desktops it is difficult to classify these products in a single category, as was proposed in the Draft 2 specification. Game consoles may now qualify in any desktop category for which they meet the definition. The Sleep mode requirement was added, because many of these systems use a substantial amount of energy in Idle and are often left on and unused for long periods of time. EPA believes there is large savings potential for game consoles automatically entering low power modes and hopes that this requirement will encourage manufacturers to include low power modes in future designs. Desktop-Derived Servers: EPA received feedback from a number of stakeholders and has concluded that the definition for desktop-derived servers is sufficient and therefore, plans to provide these products with levels separate from desktops in the final specification. EPA needs to receive data by the August 4th deadline that supports a separate category with separate levels for these products. Absent a robust data set, EPA will fold these systems back in with desktops and the definition will be removed. 413 414 Qualifying Computers With or Without WOL Enabled: 415 The following requirements should be followed when determining whether models should be qualified 416 with or without WOL: 417 418 Standby: Computers should be tested and reported as shipped for Standby. Models which will be 419 shipped with WOL enabled should be tested with WOL enabled and will qualify using the extra 420 allowance for Standby found in Table 2. 421 422 Sleep: Computers should be tested and reported as shipped for Sleep. Models sold through 423 enterprise channels, as defined in the Tier 1 Power Management Requirements (Section 3.A.3), 424 shall be tested, qualified, and shipped WOL enabled. Products going directly to consumers 425 through normal retail channels may be tested, qualified, and shipped with WOL disabled. Those 426 models sold both through enterprise channels and directly to consumers must test and meet both 427 the levels with and without WOL. 428 ENERGY STAR Program Requirements for Computers: Draft 3 Version 4.0 12 ------- 429 (3) Power Management Requirements 430 431 Shipment Requirement: 432 Products must be shipped with the display's Sleep mode set to activate within 15 minutes of user 433 inactivity. Products must be shipped with the computer's Sleep mode set to activate within 30 minutes 434 of user inactivity. Products may have more than one low power mode but these proposed criteria 435 address Sleep mode as defined in this specification. Computers shall reduce the speed of any active 436 Ethernet network links to the lowest speed supported by both ends of the link when transitioning to 437 Sleep or Standby. 438 439 All computers, regardless of distribution channel, shall have the ability to enable and disable WOL for 440 Sleep mode. Systems shipped through enterprise channels must have Wake On LAN (WOL) enabled 441 from the Sleep mode. For the purpose of this specification, "enterprise channels" are defined as sales 442 channels normally used by large and medium-sized business, government organizations, and 443 educational institutions, with the intent of identifying machines that will be used in managed client/ 444 server environments. Wth WOL enabled, any directed packet filters shall be enabled and set to an 445 industry standard default configuration. 446 447 All machines shipped to enterprise customers shall be capable of both remote and scheduled wake 448 events from Sleep mode and manufacturers shall ensure that these settings, where the manufacturer 449 has control (i.e., configured through hardware settings rather than software settings), can be managed 450 centrally with tools provided by the manufacturer. 451 452 User Education Requirement: 453 In order to ensure that purchasers/users are properly educated on the benefits of power management, 454 the manufacturer will include with each computer, one of the following: 455 456 • Information on ENERGY STAR and the benefits of power management in either a hard copy or 457 electronic copy of the user manual. This information should be near the front of the user guide; or 458 • A package or box insert on ENERGY STAR and the benefits of power management. 459 460 Either option must include the following information: 461 462 • Notice that the computer has been shipped enabled for power management and what the time 463 settings are; 464 • How to properly wake the computer from Sleep mode; 465 • Energy saving benefits; 466 • Money saving benefits; 467 • Environmental benefits 468 • Some information on ENERGY STAR and a link to www.enerqvstar.gov; and 469 • ENERGY STAR logo (used in accordance with "The ENERGY STAR Identity Guidelines" 470 available at www.enerqvstar.qov/loqos). 471 472 In addition, the manufacturer will have similar information with a link to 473 www.enerqvstar.gov/powermanaqement on the company Web site, readily accessible from computer 474 product pages, product specifications, and related content pages. 475 476 At the manufacturer's request, EPA will supply suggested facts and figures related to the above 477 criteria, template elements, or a complete template suitable for use in user guides or box inserts. 478 479 EPA's goal is to achieve a 40% enabling rate nationally by 2010; 60% by 2012; and > 80% by 2014. 480 EPA recognizes the importance of documenting enabling rates and encourages industry to develop a 481 collective strategy for securing and funding this research, and sharing findings with EPA and the 482 public. 483 ENERGY STAR Program Requirements for Computers: Draft 3 Version 4.0 13 ------- 484 485 (B) Tier 2 Requirements - Effective January 1. 2009 486 487 (1a) Tier 2 Capability Benchmark: All computers will be required to meet the following minimum 488 performance per unit energy metric. 489 490 Performance Benchmarking Software and Associated Levels: TBD 491 -OR- 492 493 (1 b) Provisional Tier 2 Idle State Requirements: If an energy efficiency performance or capability 494 benchmark, and associated performance levels, are not ready to go into effect by January 1, 2009, a 495 provisional Tier 2 specification will automatically go into effect and will remain in effect until such a 496 benchmark is established. This provisional Tier 2 will include revised Idle state levels for all computer 497 types (those included in Tier 1 as well as others as appropriate [e.g., thin clients]) with the intention of 498 capturing the top 25% performers in energy efficiency. 499 500 Additional topics, including the following, will also be re-examined under a provisional Tier 2: 501 502 • Idle levels for notebooks and integrated computers that incorporate the energy use of the displays; 503 504 • Quantitative distinctions between desktop categories (e.g., Mb of video memory, number of 505 processor cores, Mb of system memory) to make sure these distinctions remain current; 506 507 • Sleep levels for desktop-derived servers; and 508 509 • Allowances for Out-Of-Bound (OOB) client management tools, such as service processors in 510 Sleep and Standby, which may aid in the adoption of computer power management. 511 512 In the case of the implementation of a provisional Tier 2, EPA will re-examine these new topics and 513 finalize new levels at least six months prior to the effective date for Tier 2. 514 515 (2) Power Management Requirements: In addition to the requirements provided under Tier 1, 516 above, ENERGY STAR qualified computers must retain full network connectivity while in Sleep mode, 517 according to a platform-independent industry standard. All computers shall reduce their network link 518 speeds during times of low data traffic levels in accordance with any industry standards that provides 519 for quick transitions among link rates. 520 521 C) Voluntary Requirements 522 523 User Interface: Although not mandatory, manufacturers are strongly recommended to design 524 products in accordance with the Power Control User Interface Standard — IEEE 1621 (formally known 525 as "Standard for User Interface Elements in Power Control of Electronic Devices Employed in 526 Office/Consumer Environments"). Compliance with IEEE 1621 will make power controls more 527 consistent and intuitive across all electronic devices. For more information on the standard see 528 http://eetd.LBL.gov/Controls. 529 530 531 4) Test Procedures: Manufacturers are required to perform tests and self-certify those models that 532 meet the ENERGY STAR guidelines. 533 534 • In performing these tests, partner agrees to use the test procedures provided in Table 3, below. 535 536 • The test results must be reported to EPA using the Computer Version 4.0 Qualifying Product 537 Information (QPI) Form. 538 ENERGY STAR Program Requirements for Computers: Draft 3 Version 4.0 14 ------- 539 Models Capable of Operating at Multiple Voltage/Frequency Combinations: Manufacturers shall 540 test their products based on the market(s) in which the models will be sold and promoted as ENERGY 541 STAR qualified. For products that are sold as ENERGY STAR in multiple international markets and, 542 therefore, rated at multiple input voltages, the manufacturer must test at and report the required power 543 consumption or efficiency values at all relevant voltage/frequency combinations. For example, a 544 manufacturer that is shipping the same model to the United States and Europe must measure, meet 545 the specification, and report test values at both 115 Volts/60 Hz and 230 Volts/50 Hz in order to qualify 546 the model as ENERGY STAR in both markets. If a model qualifies as ENERGY STAR at only one 547 voltage/frequency combination (e.g., 115 Volts/60 Hz), then it may only be qualified and promoted as 548 ENERGY STAR in those regions that support the tested voltage/frequency combination (e.g., North 549 America and Taiwan). 550 Table 3: Test Procedures for Measuring Operational Modes Specification T . * , r. „ .

If a product model is offered in the market in multiple configurations or styles, as a product "family" or series, the partner may report and qualify the product under a single model number, as long as all of the models within that family or series meet either of the following requirements: • Computers that are built on the same platform and are identical in every respect except for housing and color may be qualified through submission of test data for a single, representative model. • If a product model is offered in the market in multiple configurations, the partner may report and qualify the product under a single model number that represents the highest power configuration available in the family, rather than reporting each and every individual model in the family. In this case, the highest configuration would consist of: the highest power processor, the maximum memory configuration, the most advanced GPU, etc. For desktop systems which meet the definition for multiple desktop categories (as defined in section 3.A.2) depending on the specific configuration, manufacturers will have to submit the highest power configuration for each category under which they would like the system to qualify. For example, a system that could be configured either as a Category A or a Category B desktop would require a submittal of the highest power configuration for both categories in order to qualify as ENERGY STAR. If a product could be configured to meet all three categories, it would then have to submit data for the highest power configuration in all categories. When submitting model families, manufacturers must confirm that every tested configuration meets ENERGY STAR Program Requirements for Computers: Draft 3 Version 4.0 15 ------- 577 the specification, but also will be held accountable for any efficiency claims made about all other 578 models in the family, including those not tested or for which data was not reported. 579 580 581 582 583 584 585 586 587 588 589 590 591 592 593 594 595 596 597 598 599 600 601 602 603 604 605 606 607 608 609 610 611 Note: EPA has included language that explains how models with multiple configurations may qualify for ENERGY STAR. The proposed approach is intended to reduce manufacturer reporting while ensuring all configurations of a given model meet the specification. Similarly, EPA is also asking manufacturers qualifying Imaging Products to submit the highest power configuration as well in response to partners' requests. For desktops, to ensure that products meet the specification under all configurations, EPA proposes that manufacturers submit data for the highest configuration for each category (e.g., A, B, and/or C) in which they want to qualify in the desktop space. EPA intends to collaborate with partners on revising the Online Product Submittal (OPS) tool to accommodate revisions to the computer specification in a way that is acceptable to both partners and EPA. 5) Effective Date: The date that manufacturers may begin to qualify products as ENERGY STAR, under this Version 4.0 specification, will be defined as the effective date of the agreement. Any previously executed agreement on the subject of ENERGY STAR qualified computers shall be terminated effective June 30, 2007. 1. Qualifying Products Under Tier 1 of the Version 4.0 Specification: The first phase of this specification will commence on July 1, 2007. All products, including models originally qualified under Version 3.0, with a date of manufacture on or after July 1, 2007, must meet the new (Version 4.0) requirements in order to qualify for ENERGY STAR. The date of manufacture is specific to each unit and is the date (e.g., month and year) of which a unit is considered to be completely assembled. 2. Qualifying Products Under Tier 2 of the Version 4.0 Specification: The second phase of this specification, Tier 2, will commence on January 1, 2009. All products, including models originally qualified under Tier 1, with a date of manufacture on or after January 1, 2009, must meet the Tier 2 requirements in order to qualify for ENERGY STAR. 3. Elimination of Grandfathering: EPA will not allow grandfathering under this Version 4.0 ENERGY STAR specification. ENERGY STAR qualification under previous versions is not automatically granted for the life of the product model. Therefore, any product sold, marketed, or identified by the manufacturing partner as ENERGY STAR must meet the current specification in effect at the time of manufacture of the product. 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. ENERGY STAR Program Requirements for Computers: Draft 3 Version 4.0 16 ------- 612 APPENDIX A 613 ENERGY STAR Test Procedure for Determining the 614 Power Use of Computers in Standby, Sleep, and Idle 615 616 The following protocol should be followed when measuring power consumption levels of computers for 617 compliance with the Standby, Sleep, and Idle levels provided in the ENERGY STAR Version 4.0 618 Computer Specification. Partners must measure a representative sample of the configuration as shipped 619 to the customer. However, the Partner does not need to consider power consumption changes that may 620 result from component additions made by the computer user after sale of product. This procedure is 621 intended to be followed in order and the mode being tested is labeled where appropriate. 622 623 I. Definitions 624 625 Unless otherwise specified, all terms used in this document are consistent with the definitions 626 contained in the Version 4.0 ENERGY STAR Eligibility Criteria for Computers. 627 628 UUT 629 UUT is an acronym for "unit under test," which in this case refers to the computer being tested. 630 631 UPS 632 UPS is an acronym for "Uninterruptible Power System," which refers to a combination of converters, 633 switches and energy storage means, for example batteries, constituting a power system for 634 maintaining continuity of load power in case of input power failure. 635 636 637 II. Testing Requirements 638 639 Approved Meter 640 Approved meters will include the following attributes1: 641 642 • Power resolution of 1 mW or better; 643 • An available current crest factor of 3 or more at its rated range value; and 644 • Lower bound on the current range of 10mA or less. 645 646 EPA also suggests the following attributes in addition to those above: 647 648 • Frequency response of at least 3 kHz; and 649 • Calibration with a standard that is traceable to the U.S. National Institute of Standards and 650 Technology (NIST). 651 652 It is also desirable for measurement instruments to be able to average power accurately over any user 653 selected time interval (this is usually done with an internal math's calculation dividing accumulated 654 energy by time within the meter, which is the most accurate approach). As an alternative, the 655 measurement instrument would have to be capable of integrating energy over any user selected time 656 interval with an energy resolution of less than or equal to 0.1 mWh and integrating time displayed with 657 a resolution of 1 second or less. 658 659 Accuracy 660 Measurements of power of 0.5 W or greater shall be made with an uncertainty of less than or equal to 661 2% at the 95% confidence level. Measurements of power of less than 0.5 W shall be made with an 662 uncertainty of less than or equal to 0.01 W at the 95% confidence level. The power measurement 663 instrument shall have a resolution of: 1 Characteristics of approved meters taken from IEC 62301 Ed 1.0: Measurement of Standby Power ENERGY STAR Program Requirements for Computers: Draft 3 Version 4.0 17 ------- 664 665 • 0.01 W or better for power measurements of 10 W or less; 666 • 0.1 Wor better for power measurements of greater than 10 W up to 100 W; and 667 • 1 W or better for power measurements of greater than 100 W. 668 669 All power figures should be in watts and rounded to the second decimal place. For loads greater than 670 or equal to 10 W, three significant figures shall be reported. 671 672 Test Conditions 673 • Line Impedance: < 0.25 ohm 674 • Total Harmonic Distortion: < 5% 675 • Ambiant Temperature: 25 degrees C +/- 3 degrees C 676 • For products to be qualified in markets using 100V / 120V input: 677 - Input AC Voltage: 115 VAC RMS +/- 5 V RMS 678 - Input AC Frequency: 60 Hz +/- 3 Hz 679 • For products to be qualified in markets using 230 V input: 680 - Input AC Voltage: 230 VAC RMS +/- 5V RMS 681 - Input AC Frequency: 50 Hz +/- 3 Hz 682 683 Test Configuration 684 Power consumption of a computer shall be measured and tested from an ac source to the UUT. 685 686 The UUT must be connected to an Ethernet network switch capable of the UUT's highest and lowest 687 network speeds. The network connection must be live during all tests. 688 Note: Based on stakeholder comments, the Ethernet network switch is now specified to be capable of the highest and lowest network speed of the UUT. This will allow for increased repeatability as all systems will be able to drop to the lowest link speed during the tests. 689 690 691 III. Test Procedure 692 Measurement of ac power consumption of a computer should be conducted as follows: 693 694 UUT Preparation 695 1. Record the manufacturer and model name of the UUT. 696 2. Ensure that the UUT is connected to a live Ethernet (IEEE 802.3) network switch as specified in 697 Section II., "Test Configuration," above, and that the connection is live. The computer must 698 maintain this live connection to the switch for the duration of testing, disregarding brief lapses 699 when transitioning between link speeds. 700 3. Connect an approved meter capable of measuring true power to an ac line voltage source set to 701 the appropriate voltage/frequency combination for the test. 702 4. Plug the UUT into the measurement power outlet on the meter. No power strips or UPS units 703 should be connected between the meter and the UUT. For a valid test to take place the meter 704 should remain in place until all Standby, Sleep, and Idle power data is recorded. 705 5. Record the ac voltage. 706 6. Boot computer and wait until the operating system has fully loaded. 707 7. Record basic information about the computer's configuration - computer type, operating system 708 name and version, processor type and speed, and total and available physical memory, etc.2 709 8. Record basic information about the video card - video card name, resolution, amount of onboard 710 memory, and bits per pixel.3 2 On Windows-based machines, much of this can be found by selecting the following window: Start / Programs / Accessories / System Tools / System Information. ENERGY STAR Program Requirements for Computers: Draft 3 Version 4.0 ------- 711 9. Ensure that the UUT is configured as shipped including all accessories, power management 712 settings, WOL enabling and software shipped by default. UUT should also be configured using 713 the following requirements for all tests: 714 a. Desktop systems (including workstations and desktop-derived servers) shipped without 715 accessories should be configured with a standard mouse, keyboard and external monitor. 716 b. Notebooks and tablets should include all accessories shipped with the system, and need 717 not include a separate keyboard or mouse when equipped with an integrated pointing 718 device or digitizer. 719 c. Notebooks and tablets should have the batteries removed for all tests. 720 d. Power to wireless radios should remain configured as shipped. Systems shipped with 721 wireless radios enabled should ensure that the adapters remain enabled, but the system 722 should not be connected to an active wireless link for testing. This requirement applies to 723 wireless network adapters (e.g., 802.11) or device to device wireless protocols. 724 10. For computers with integrated monitors (notebooks, tablets and integrated systems), use the 725 power management settings to set the monitor to power down after 1 minute (adjust no other 726 power management settings). 727 11. Shut down the computer. 728 745 746 747 748 Note: Some stakeholders commented that the test procedure should explicitly state that wireless adapters should be turned off for all tests. EPA believes it is important to capture the power consumption of these devices, but has specified that these wireless devices should not be actively connected to a network or device during testing. 729 730 731 Standby (Off Mode) Testing 732 12. With the UUT shut down and in Standby, set the meter to begin accumulating true power values at 733 an interval of 1 reading per second. Accumulate power values for 5 additional minutes and record 734 the average (arithmetic mean) value observed during that 5 minute period.4 735 736 Idle Mode Testing 737 13. Switch on the computer and begin recording elapsed time, starting either when the computer is 738 initially switched on, or after completing any log in activity necessary to fully boot the system. 739 Once logged in with the operating system fully loaded and ready, close any open windows so that 740 the standard operational desktop screen or equivalent ready screen is displayed. Exactly 10 741 minutes after the initial boot or log in, set the meter to begin accumulating true power values at an 742 interval of 1 reading per second. Accumulate power values for 5 additional minutes and record 743 the average (arithmetic mean) value observed during that 5 minute period. 744 Note: Based on stakeholder comment, the Idle test procedure has been modified to begin Idle measurements from either the initial switching on of the UUT or from the completion of any necessary log in procedures. This change was made to increase repeatability for computers with required log in. To minimize the impact of the difference between these two start points, and to ensure all computers have fully loaded and settled into the Idle state, measurement will now begin after a 10 minute wait interval. The language has also been clarified to indicate more clearly that all windows must be closed after the user has logged in, to display the standard desktop screen or ready screen. 3 On Windows-based machines, this can be found by selecting the following window: Start / Programs /Accessories / System Tools / Components / Display. 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. ENERGY STAR Program Requirements for Computers: Draft 3 Version 4.0 19 ------- 749 Sleep Mode Testing 750 14. After completing the Idle measurements, place the computer in Sleep mode. Reset the meter (if 751 necessary) and begin accumulating true power values at an interval of 1 reading per second. 752 Accumulate power values for 5 additional minutes and record the average (arithmetic mean) value 753 observed during that 5 minute period. 754 15. If testing both WOL enabled and WOL disabled for Sleep, wake the computer and change the 755 WOL from Sleep setting through the operating system settings or by other means. Place the 756 computer back in Sleep mode and repeat step 14, recording Standby power for this alternate 757 configuration. 758 759 Reporting Test Results 760 16. The test results must be reported to EPA using the Online Product Submittal (OPS) Tool, taking 761 care to ensure that all required information has been included. 762 763 IV. Continuing Verification 764 765 This testing procedure describes the method by which a single unit may be tested for compliance. An 766 ongoing testing process is highly recommended to ensure that products from different production runs 767 are in compliance with ENERGY STAR. 768 ENERGY STAR Program Requirements for Computers: Draft 3 Version 4.0 20 ------- |
