For Organizations

By joining the Initiative, our members commit to specifying systems that meet or exceed the latest ENERGY STAR specification for a majority of their corporate personal computer and volume server purchases. In addition to fulfilling purchase requirements, members also commit to use computer power management features whenever possible.

Because changing your organization’s purchasing requirements and implementing power management can be a significant undertaking, Climate Savers Computing offer new members a one-year grace period for compliance with the program criteria. The first-year ‘on-boarding’ period gives new members an opportunity to ramp up to the criteria requirements of the following year.

The tables below lists the minimum percentage of total procurements requested from Climate Savers Computing Initiative participants at each efficiency level in a given year.

*Specifications are for volume servers that are 1S, 2S, 4S and blade servers.

Example:
A member who joins in December 2009 will need to ensure 50% of their Personal Computer purchases meet or exceed the ENERGY STAR specification. Once the one-year grace period is complete in December 2010, the member would be required to meet the existing criteria for the July’10-June’11 program year. If the member planned to buy 1,000 new desktop computers and 10 new servers in January 2011, they would break down as follows:

  • All 1,000 of the desktop computers should be Energy Star 5.0 qualified
  • Of the 1,000 desktop computers, 800 or more should have a power supply that is at least 85% energy-efficient (in addition to being Energy Star 5.0 qualified)
  • Of those 800 desktop computers, 200 or more should have a power supply that is at least 88% energy-efficient (in addition to being Energy Star 5.0 qualified)
  • Eight or more of the 10 new servers purchased should have a power supply that is at least 85% energy-efficient and be Energy Star Tier 1 Server Specification qualified.
  • Four or more of the 10 new servers should have a power supply that is at least 89% energy-efficient and be Energy Star Tier 1 Server Specification qualified.

Power Management Requirements

In addition to efficiency specifications, members must use power management features such as the "sleep" or "hibernate" settings on client computers, whenever possible. The Initiative’s power management policies recommend computers turn off the display and hard drive after 15 minutes of inactivity, and put the system into "sleep" mode after 30 minutes of inactivity. Members are given a one-year grace period for planning and piloting power management before broad deployment. At the conclusion of the one-year grace period, members are expected to meet the full requirements for power management deployment.

For Computer and Server Manufacturers

The baseline requirement for all Climate Savers Computing qualified PCs, laptops, and workstations is meeting the current effective ENERGY STAR specification.  Bronze, Silver, and Gold level systems must also meet the additional power supply unit (PSU) energy efficiency requirements outlined below.

Climate Savers Computing requirements for systems with multi output power supply units. (These systems typically include desktop PCs, thin clients, and workstations):
  1. Climate Savers Computing Bronze: Current effective ENERGY STAR specification PLUS an 85% minimum efficiency rating for the PSU at 50% of rated output (and 82% minimum efficiency at 20% and 100% of rated output) and a power factor of at least 0.9 at 50% of rated output.
  2. Climate Savers Computing Silver:  Current effective ENERGY STAR specification PLUS an 88% minimum efficiency rating for the PSU at 50% of rated output (and 85% minimum efficiency at 20% and 100% of rated output) and a power factor of at least 0.9 at 50% of rated output.
  3. Climate Savers Computing Gold: Current effective ENERGY STAR specification PLUS a 90% minimum efficiency rating for the PSU at 50% of rated output (and 87% minimum efficiency at 20% and 100% of rated output) and a power factor of at least 0.9 at 50% of rated output.
Climate Savers Computing requirements for systems with single output power supply units. (These systems typically are volume servers, including single, dual and 4 socket-servers in pedestal and rack form factors and blade servers capable of having up to four processors):
  1. Climate Savers Computing Silver: Volume servers must meet current effective ENERGY STAR server specification PLUS installed PSU that meets CSCI silver PSU requirements. See below under equipment manufacturer specifications.
  2. Climate Savers Computing Gold: Volume servers must meet current effective ENERGY STAR server specification PLUS installed PSU that meets CSCI gold PSU requirements. See below under equipment manufacturer specifications.
  3. Climate Savers Computing Platinum: Volume servers must meet current effective ENERGY STAR server specification PLUS installed PSU that meets CSCI platinum PSU requirements. See below under equipment manufacturer specifications.

PSU Equipment Manufacturers

System manufacturers participating in the Climate Savers Computing Initiative have committed to working to develop products that meet or exceed the Initiative’s Program Criteria. The following system types are currently included in the Climate Savers Computing specifications:

  • Clients (typically featuring multi-output PSUs)
  • Workstations (typically featuring multi-output PSUs)
  • Single, dual and 4 socket-servers in pedestal and rack form factors (single and multi output PSUs)
  • Blade servers capable of having up to four processors
  • Note that Climate Savers Computing has not defined a separate client specification for laptop computers. Laptops are covered by the ENERGY STAR external PSU requirements.

The tables below outline the required efficiency levels for power supply units (both multi-output and single-output) at various loading conditions and power factor levels. In order for systems to comply with Climate Savers Computing specifications, systems must feature power supplies at the efficiency levels outlined in the charts below.
