Kerry L. Hazelrigg, The Walt Disney Company

This webcast provides an exclusive, detailed review of the "ROI of Cooling System Energy Efficiency Upgrades" case study. The study reviewed the effects on Power Usage Effectiveness (PUE) and ROI of five types of energy efficiency initiatives in the data center – installing VSDs, upgrading CRAH units, implementing rack airflow management, moving the CRAH control from the return air temperature to the rack inlet, and increasing the temperature set points of the CRAH and chiller units. The results of this study allow The Green Grid to provide operators with a set improvement metrics and ROI models intended to assist data center operators with building credible business cases for performing energy efficiency improvements.
