Computer and Monitors Purchasing & Procurement Language
What ENERGY STAR Purchasing & Procurement resources does EPA offer?
ENERGY STAR Purchasing & Procurement resources include lists of qualifying products, key product criteria, drop-in procurement language and savings calculators. Organizations can use these resources to facilitate the procurement of energy-efficient ENERGY STAR products and prevent greenhouse gas emissions.
Sample Procurement Language (Download Office Product Procurement Language)
The following is an example of language you may wish to require in your upcoming contract:
The Vendor Must:
Provide new and repaired computers, monitors, and integrated computer-monitor systems that earn the ENERGY STAR and are configured properly for automatic energy-saving features, as per current ENERGY STAR specifications. The vendor shall provide customer support with respect to power management features, such that these features remain properly enabled and repaired if a malfunction occurs. The vendor is encouraged to visit www.energystar.gov for complete product specifications and an updated list of qualifying products.
Key Product Criteria for ENERGY STAR Qualified Computers
| Tier 1 Energy Efficiency Requirements: Effective July 20, 2007 | |
|---|---|
| Product Type | Tier 1 Requirements |
| Desktops, Integrated Computers, Desktop-Derived Servers and Gaming Consoles | Standby (Off Mode): <= 2.0 W Sleep Mode: <= 4.0 W Idle State*:
|
| Notebooks and Tablets | Standby (Off Mode): <= 1.0 W Sleep Mode: <= 1.7 W Idle State*:
|
| Workstations | TEC Power (PTEC): <= 0.35 * [PMAX + (#HDDs * 5)] W Note: Where Pmax is the maximum power drawn by the system as tested per the test procedure in Section 4 of Appendix A, and #HDD is the number of installed hard drives in the system. |
| Tier 1 Power Supply and Power Management Requirements: Effective July 20, 2007 | |
|---|---|
| Efficient power supply requirements | Internal power supplies: 80% minimum efficiency at 20%, 50%, and 100% of rated output and minimum Power Factor 0.9 OR External power supplies: either ENERGY STAR qualified or meet the no-load and active mode efficiency levels provided in the ENERGY STAR External Power Supply (EPS) specification |
| Power Management | Monitor Sleep Mode: within 15 minutes of user inactivity System Sleep Mode: within 30 minutes of user inactivity |
Key Product Criteria for ENERGY STAR Qualified Monitors
(effective January 1, 2005)
| On Mode | Sleep Mode | Off Mode | |
|---|---|---|---|
| Tier 1 Maximum Allowable Power Consumption: Effective January 1, 2005 | Y = 38X + 30. Y is expressed in watts and rounded up to the nearest whole number and X is the number of megapixels in decimal form |
<= 4 watts | <= 2 watts |
| Tier 2 Maximum Allowable Power Consumption: Effective January 1, 2006 | If X < 1 megapixel, then Y = 23; if X > 1 megapixel, then Y = 28X. Y is expressed in watts and rounded up to the nearest whole number and X is the number of megapixels in decimal form |
<= 2 watts | <= 1 watts |
*Note: The time that a monitor takes to enter into the first low power “sleep mode” and the second low-power "deep sleep" mode shall not exceed 60 minutes.
Additional considerations for the procurement official:
- You, or other individuals in your organization, may adjust the power management setting to conform to unique work patterns. If you have questions about activating or changing the sleep feature, refer to the owners’ manual, call the manufacturer’s help line, or visit www.energystar.gov/powermanagement.
- If your business operates on a local area network (LAN), be sure to specify that the power management feature on your computer is compatible with the existing network system.
