Recently，NRCan (Natural Resources Canada) release of the final Version 4.0 ENERGY STAR Computer Server Specification. The version 4.0 requirements will take effect on January 12, 2024.

The Version 4.0 specification will recognize the top performing computer server products on the market. ENERGY STAR certified computer servers with power management enabled will use, on average, approximately 38% less energy than standard computer.

In response to the final draft specification, limited comments were received that focused on improving clarity within the specification, which have been addressed in the final document. Clarifications of the definitions for Storage Heavy Servers, Auxiliary Processing Accelerator (APA) and High and Low End Performance Configurations have been incorporated. New definitions for Field Programmable Gate Array and Data Processing Units were included to support the changes to the APA definition. In addition, the footnote related to power supplies was amended to clarify that the power supply values used for servers should be at 230V/60Hz rather than 115V/60Hz. Finally, small changes were made to the scope, to exclude products that would never be sold without an APA.

Version 4.0 Transition Timeline and Next Steps:

The following timeline aims to facilitate a smooth transition from one ENERGY STAR specification to the next, meet consumer expectations, and ensure that ENERGY STAR labeled products fully meet the new requirements upon their effective date.

• Effective immediately, manufacturers may elect to have their Certification Body (CB) certify eligible products to the Version 4.0 requirements.

• CBs must upload required SERT files specified in Section 4.1.2.v of the specification to the Environmental Protection Agency (EPA) in a location to be determined which will be shared with CBs upon the release of the final QPX form.

• After August 30, 2023, CBs will be instructed to stop certifying new product submittals to Version 3.0. Note, however, that existing certifications to V3.0 will remain valid for the purposes of ENERGY STAR certification until January 12, 2024.

• Any computer server manufactured as of January 12, 2024, must meet the Version 4.0 requirements to bear the ENERGY STAR mark. All certifications of products to the Version 3.0 specification will be invalid for purposes of ENERGY STAR and CBs will only submit product models certified to Version 4.0 to EPA.
