ENERGY STAR® certified products

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

Recent Activities

IBM actively participated in the development of the ENERGY STAR specifications for server and storage products, providing technical assistance and equipment operating data to assist in the development of criteria and to inform the EPA on IT equipment capabilities. IBM continues to work with the EPA, the Information Technology Industry Council, and The Green Grid to collect Standard Performance Evaluation Corporation (SPEC) Server Efficiency Rating Tool (SERT) and Storage Networking Industry Association (SNIA) EmeraldTM Power Efficiency Measurement test data for server and storage products, respectively, to assess how component choices affect the metric scores, and evaluate options to use the metrics to set performance/power based energy efficiency thresholds for the products.
