ENERGY STAR Computers Version 8.0 Final Draft

Wed, 10/23/2019 - 15:54 -- MrGreen

The Final Draft Specification and Test Method for ENERGY STAR™ Computers Version 8.0 were released on September 10 by the U.S. Environmental Protection Agency (EPA). Considering stakeholder feedback while maintaining balance among criteria, the Version 8.0 specification anticipates an effective date of July 15, 2020.

In the final draft, the EPA has made some adjustments to functional adder allowances. The 3.5” hard disk drive (HDD) adder for desktops and integrated desktops is reduced from 21 kWh/year to 16.5 kWh/year, whereas the 3.5” HDD adder for notebook storage is no longer applicable, and a single adder of 2.6 kWh/year is retained for all other notebook storage types. For higher throughput ports used by higher end content creation products, new adders depend on Ethernet port throughput ratings, i.e. 4.0 kWh/year for 2.5-5 Gb/s or 18.0 kWh/year for 10 Gb/s. The EPA has also adjusted base allowances slightly to account for changes to the adder values.

Furthermore, by re-structuring allowances, the EPA is providing more access to incentives for integrated desktops. To qualify for the full capability mode weighting and applicable incentives, notebook or integrated desktop products shall be capable of sleep mode or an alternative low power mode which maintains constant network connectivity while consuming less than or equal to 2.5 W. Similarly, the requirement applies to desktop computers but with energy consumption less than or equal to 3.0 W. The EPA believes that the revised incentive structure will push products to use less overall energy than currently achieved by traditional sleep and long idle modes, while enabling more functionality for end users.

Finally, the test method reference has been updated to reflect the latest draft test method.
