ENERGY STAR® certified products

IBM has a long history with the U.S. Environmental Protection Agency's (EPA) ENERGY STAR program. ENERGY STAR is a voluntary program which sets energy efficiency and labeling requirements for different product types to identify and promote energy-efficient products.

One of IBM's product energy efficiency goals is to qualify its new server and storage products to the ENERGY STAR program criteria where practical, and where criteria have been developed for the specific server or storage product type. Version 2 of the ENERGY STAR program requirements for computer servers became effective December 16, 2013. Version 1 of the ENERGY STAR program requirements for storage products became effective on December 6, 2013.

In 2015, the IBM Power SystemsTM S812LC, S822L, S822LC and E850 were certified to the ENERGY STAR server requirements (Version 2). The IBM FlashSystemTM 900, IBM XIV® Gen3 storage system, and IBM Storwize® V3700 storage products had some of their available configurations certified against Version 1 of the ENERGY STAR data center storage requirements.

As of May 2016, IBM had six Power® server and three storage machine types certified to the ENERGY STAR requirements. The Power servers meet the EPA's requirements for power-supply efficiency, idle power limits or power management capability, and Standard Performance Evaluation Corporation (SPEC) Server Efficiency Rating Tool (SERT) metric data reporting. The storage products meet requirements for power-supply efficiency and reporting of Storage Network Industry Association (SNIA) Emerald Power Efficiency Measurement Specification results.

Regulatory Development Activities

IBM actively assists in the development of external product energy efficiency standards. In 1992, IBM became a charter member of the EPA's ENERGY STAR computer program and helped to develop the first ENERGY STAR criteria for personal computers. Since then, we have continued our support for the ENERGY STAR program, assisting in the development of new criteria and certifying products that comply with the criteria. Today, IBM engineers are actively participating in the development of updates to the ENERGY STAR requirements for server and storage products.

We are providing technical assistance regarding the assessment of the Standard Performance Evaluation Committee (SPEC) Server Efficiency Rating Tool (SERT) and the Storage Network Industry Association (SNIA) Emerald Power Efficiency Measurement Specification. In addition, we are:


Past Achievements

IBM became a charter member of the U.S. EPA's ENERGY STAR Computer Program in 1992 and helped the EPA define criteria for computers and monitors.

In March 2001, IBM became the first company to win an ENERGY STAR Excellence in Corporate Commitment Award recognizing IBM's overall commitment and contributions to energy conservation and efficiency across the company's operations and in the design of its products. IBM also received the ENERGY STAR Computer Partner of the Year award in the Office Equipment category for two consecutive years, 1998 and 1999, for leadership in developing environmentally responsible computer products.
