This resource provides a general overview of the most commonly used energy efficiency strategies in data centers. There is a brief description of each strategy, followed by practical implementation considerations such as:
- How the strategy is implemented;
- How much its costs;
- How much it can save;
- Risks involved with implementation;
- Where to find additional information.
This resource was developed to help IT professionals, facility managers, energy managers, and sustainability coordinators identify and understand opportunities in existing data centers. For new facilities, the US Department of Energy (DOE) offers a Best Practices Guide for Energy-Efficient Data Center Design (887KB). DOE also offers a number of data center analysis tools and case studies, along with a Data Center Energy Practitioner training program, which qualifies professionals to identify and evaluate energy efficiency opportunities in data centers. The Green Grid recently completed a comprehensive analysis 
of return on investment and power usage effectiveness at a data center for installing variable speed fans, adding baffles and blanking panels, repositioning temperature/humidity sensors, and adjusting temperature setpoints.
EBay recently completed a case study (579KB) with EPA ENERGY STAR that showed paybacks of one-half year for ultrasonic humidification and less than two years for variable speed drives retrofits at their Phoenix data center.
EPA ENERGY STAR recognized technical teams from BNY Mellon, RagingWire, and Target as "Low Carbon IT Champions" for the energy efficiency upgrades undertaken that led to ENERGY STAR building certification for their data center. View the case studies that highlight many of the measures in the Top 12 and public service announcements recognizing their achievements.
