2 Data Center Benchmarking Initiative

3 A benchmark is a point of reference for measurement THE RANGE OF USES INCLUDES:! Comparing with typical examples where do we fit?! Comparing with best practice are we doing well?! Setting a challenge better? can we do! Setting targets achieve we plan to! Avoiding exaggeration are our targets realistic?! Follow-through reality checks is the design drifting off?! Providing feedback did we meet our goals?! Providing insights if not, why not, what can we learn? IT IS NOT an end in itself, e.g. meeting the benchmark BUT a means of developing understanding Source: Bill Bordass and motivating improvement.

4 What does Benchmarking do? Benchmarking! Serves as an excellent baseline "report card! Identifies specific problem areas and eliminates guesswork! Helps to prioritize improvement opportunities! Makes it easier to increase performance expectations and "raise the bar"! Creates a sense of competitiveness and shifts the market towards better-performing levels.

5 Benefits of Benchmarking! Designers, Owners and Users Designers /ESCOs Building performance targets for new and existing data centers Owners/Users Measure the performance of their data centers Building portfolio managers can compare the performance of individual facilities to others! Data Center Developers and Operators Helps to assess the potential savings Use of appropriate products and technologies! Policy Makers Reward/Incentivize exemplary building performance and penalize/discourage poor building performance
