The -S system typically represents an efficiency opportunity in most data centers. &nthis data center, the -S was on an a#erage loaded to appro"imately of its ratedcapacity. Since -S efficiency is higher at higher load factors, loading to 2: total for6 system or 0: for each module is good from an efficiency point of #iew. Theefficiency at this load factor was obser#ed to be appro"imately . This means thatthe -S efficiency is about a#erage for all systems benchmar!ed at this load factor.

&n addition to these recommendations, the following strategies are recommended>

+. &t is recommended that the company management in#estigate and adopt atotal cost of ownership approach to their data centers. )nergy costs arealready eclipsing the cost of the &T e%uipment o#er its life and this willonly get worse as energy prices rise. &f actions re%uiring capital were notta!en in the past without regard to the ongoing energy sa#ings, thispractice should be re#iewed.

6. An energy manager should be established with responsibility formonitoring energy performance and trac!ing impro#ements o#er time.Specific goals GtargetsH for energy reduction should be implemented alongwith the commitment for capital e"penditures where return on in#estmentwarrants.

9. &f the company operates multiple centers, a mechanism to share bestpractices should be established.
