Vision for Energy Efficiency in Data Centers1. Establish metrics for overall data center energy

intensity

• IT and infrastructure

• Energy cost ($), source energy (Btu),and carbon emissions (M tons)

• Specified Best-in-Class targets forvarious types of data centers

2. Create tools and guidelines to drivecontinuous improvement

3. Support third-party certification process to validateenergy intensity improvement and Best-in-Class

4. Provide recognition for data centers that achievea certain level of energy savings
