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 2014 the IBM Power SystemsTM S822, S822L, and S824 were certified to the ENERGY STAR server requirements (Version 2). The IBM FlashSystemTM 840, IBM XIV® storage system, and V3700 storage products had some or all of their available configurations ENERGY STAR certified against Version 1 of the storage requirements.

As of May 2015, IBM had certified seven IBM Power® servers and three storage machine types to the ENERGY STAR requirements. The IBM 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 the Storage Network Industry Association (SNIA) Emerald Power Efficiency Measurement Specification.

Regulatory Development Activities

IBM actively assists in the development of external product energy efficiency standards. As in 1992 when we helped to develop and were a charter member of the EPA's ENERGY STAR computer program, IBM staff 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 SNIA Emerald Power Efficiency Measurement Specification, working both inside IBM and in conjunction with industry groups to evaluate the SERT and Emerald results. We are also assisting the EPA and various regulatory bodies outside the United States in developing server energy efficiency criteria based on the SERT metric. Our activities have expanded to include providing extensive comments and technical data to the European Union Energy-related Products (ErP) Lot 9 Study on Server and Storage products and to the China National Institute of Standardization's server energy efficiency requirements effort.

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.
