Track: Modeling Throughout the Building Life Cycle
Sponsor: 9.9 Mission Critical Facilities, Data Centers, Technology Spaces and Electronic Equipment
Chair: Nick Gangemi, Life Member, Northern Air Systems, Rochester, NY

The only metric in common use for measuring data center performance is PUE. Yet, PUE is criticized because other than power delivery, PUE does not measure data center performance. This seminar describes a first step by The Green Grid to measure, predict and display cooling performance using the Performance Indicator so that business and technical stakeholders can understand cooling performance. A case study uses modeling to help save energy and dollars even environment to protect the IT is the top priority. The seminar concludes using case study data to look at what is needed to measure and model successfully.

1. The Performance Indicator: A Data Center Cooling Performance View
Mark Seymour, CEng, Member, Future Facilities Ltd, London, United Kingdom
Following the development of PUE by The Green Grid (TGG) more than 10 years ago, it has been adopted as a common standard of performance measurement of data center energy efficiency. Although in common use it is criticized because of the possibility of 'gaming' the calculation, but importantly because it is an incomplete metric. As a step towards a more complete view, TGG business stakeholders alike. This seminar presents the basis of PI and why you should use it.

2. Using Modeling and Metrics to Improve the Citigroup Flextech Upgrade
Christian Pastrana, P.E., Associate Member, Citigroup, New York, NY
When Citigroup wanted to improve their NYC data center's efficiency without compromising its performance, they built a detailed CFD model of their data center, and used the simulation results to pinpoint thermal issues. Citigroup then used the model to design and simulate solutions to these issues, resulting in the potential for over $400,000 of annual energy cost savings and a 4-month ROI after implementation. This presentation explains the use of modeling and metrics in the context of a case study and culminates showing that the performance metrics have been improved satisfying the business targets.

3. Quantifying Data Center Cooling Performance
Kourosh Nemati, Ph.D., Future Facilities Incorporated, New York, NY
The only metric in common use measuring data center performance is PUE. Yet, PUE only indicates power delivery effectiveness and doesn't represent data center cooling performance. The latter has considerable impact on PUE. There is a need for more complete metrics. This presentation looks at The Green Grid's Performance Indicator (PI) and, with a view to a possible LBNL future project to establish a more complete data set and guidance, it considers what data is readily available, Performance Indicator view for data centers already assessed and how your target PI score might depend on your data center type.
