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 90 91 92 93 94 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. 156 ENERGY STAR Program Requirements for Computers: Draft 2 Version 4.0 ------- L62_ ENERGY STAR Program Requirements for Computers Eligibility Criteria DRAFT 2 163 164 165 166 167 168 169 170 171 172 173 174 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 303 304 305 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. ENERGY STAR Program Requirements for Computers: Draft 2 Version 4.0 10 ------- 395 Table 1: Tier 1 Energy Efficiency Requirements Product Type Tier 1 Requirements Standby (Off Mode): < 2 W Sleep Mode: < 4 W Desktops, Integrated Computers, Gaming Consoles, and Desktop Derived Servers Idle State: Category A: < 75 W Category B: < 50 W Note: Game consoles and desktop-derived servers: (1) are exempt from the Sleep level above and (2) must meet the Category A Idle requirement. Only Game consoles that meet the required characteristics for Category A may qualify for ENERGY STAR at this time. Standby (Off Mode): < 1.75 W Notebooks Sleep Mode: < 3 W Idle State: < 20 W Standby (Off Mode): < 2 W Workstations Sleep Mode: < 7 W Idle State: < 115 W 396 Table 2: Tier 1 Capability Adders for Sleep and Standby WOL from Sleep and/or Standby .7 Watts System Memory from Sleep .2 Watts per memory module greater than two 397 398 Qualifying computers with or without WOL enabled: The following requirements should be 399 followed when determining whether models should be qualified with or without WOL: 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. 411 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 ENERGY STAR logo 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). 533 Table 3: Test Procedures for Measuring Operational Modes Specification ^.gst pr0t0C0| Source Requirement Standby (Off Mode), Sleep Mode, Idle State ENERGY STAR Computer Test Method (Version 4.0) Appendix A Power Supply Efficiency IPS: Draft Internal Power Supply Efficiency Protocol EPS: ENERGY STAR Test Method for External Power Supplies IPS: www.efficientpowersupplies.org EPS: www.energystar.gov/powersupplies 534 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. 559 560 561 562 563 564 565 ENERGY STAR Program Requirements for Computers: Draft 2 Version 4.0 17 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 1 Characteristics of approved meters taken from I EC 62301 Ed 1.0: Measurement of Standby Power 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. ENERGY STAR Program Requirements for Computers: Draft 2 Version 4.0 19 ------- 659 660 661 662 663 664 665 666 667 668 669 670 671 672 673 674 675 676 677 678 679 680 681 682 683 7. Record basic information about the computer's configuration - computer type, operating system name and version, processor type and speed, front side bus speed, L2 Cache size, and total and available physical memory.2 8. Record basic information about the video card, including video card name, resolution, amount of onboard memory, and bits per pixel.3 9. Ensure that the UUT is configured as shipped including all accessories, power management settings, WOL enabling and software shipped by default. UUTs should also be configured using 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.

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 2 Version 4.0 20 ------- 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. 713 ENERGY STAR Program Requirements for Computers: Draft 2 Version 4.0 21 ------- |
