Green Grid - DOE Energy Savings Goal; 10.7 billion kWh/yr by 2011 DOE-Green Grid Goal for Energy Savings Goal is 10% overall US data center energy savings by 2011 10.7 billion kWh Equivalent to electricity consumed by 1 million typical U.S. households Reduces greenhouse gas emissions by 6.5 million metrics tons of CO2 per year Green Grid - DOE Energy Savings Goal; 10.7 billion kWh/yr by 2011 Source: “Report to Congress on Server and Data Center Energy Efficiency Public Law 109-431” US EPA, August 2, 2007

Vision for Energy Efficiency in Data Centers 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 for various types of data centers Create tools and guidelines to drive continuous improvement Support third-party certification process to validate energy intensity improvement and Best-in-Class Provide recognition for data centers that achieve a certain level of energy savings

Save Energy Now: Products & Services Tools Information Process Heating Steam Systems Plant Energy Profiler Motors & Pumps Fans Website Information Center Tip Sheets Case studies Webcasts Assessments Training Basic Advanced Qualified Specialist Energy Savings Assessments Industrial Assessment Centers

450 Save Energy Now Assessments Were Completed Across United States in 2006 and 2007 ITP chose to focus on the largest manufacturing plants for the 2006 Energy Savings Assessments. In the US, industrial energy use is highly concentrated, with the largest energy users consuming 58% of all industrial energy. We reached 75 of the largest energy users in 2006. 7

DOE Save Energy Now Data Center Program Major Program Elements 1. Develop Software Tool Suite 2. Create consensus metrics 3. Create and publicize Save Energy Now case studies through performing pilot energy assessments 4. Create best practice information and a training curriculum 5. Develop Qualified Specialists program for Data Centers 6. Create guidelines for “Best-in-Class” data center in various classes of data centers, including strategies for incorporating distributed generation technologies

Industrial Technologies Program Tool suite & metrics Energy baselining Training Qualified specialists Case studies Certification of continual improvement Recognition of high energy savers Best practice information Best-in-Class guidelines Federal Energy Management Program Best practices showcased at Federal data centers Pilot adoption of Best-in-Class guidelines at Federal data centers Adoption of to-be-developed industry standard for Best-in-Class at newly constructed Federal data centers Industry Tools Metrics Training Best practice information Best-in-Class guidelines IT work productivity standard EPA Metrics Server performance rating & ENERGY STAR label Data center performance benchmarking

Tools and Metrics Help to Find Energy Efficiency Opportunities Better air management Move to liquid cooling Optimized chilled-water plants Use of free cooling Load management Server innovation Power Conversion & Distribution Server Load/ Computing Operations Cooling Equipment On-site generation CHP applications Waste heat for cooling Use of renewable energy Fuel cells High voltage distribution Use of DC power Highly efficient UPS systems Efficient redundancy strategies Alternative Power Generation

Develop Software Tool Suite Tools to define baseline energy use of data center and identify key energy-saving opportunities Determine general performance of the data center Benchmark subsystems Assess energy savings potential Track energy intensity improvement Provide quantification of key metrics including cost ($), primary energy (Btu), and carbon

Develop Software Tool Suite Complete 10 pilot assessments to test the Tool Suite, Release beta version Hold industry tool and metrics workshop Complete beta testing and release Version 1.0 Q4 2007 Q1 2008 Q2 2008 Q3 2008 12/18/2007 04/01/2008 08/01/2008 Projected Timeline
