The document discusses how small gains in energy efficiency for data center equipment like UPS systems can result in millions of dollars saved over the lifespan of the equipment when considering total cost of ownership (TCO). It provides an example where a 1% improvement in UPS efficiency from 93% to 94% saves $1.4 million over 10 years of operation. Newer UPS technologies can achieve as high as 96.5% efficiency, saving almost $3.4 million compared to 93% efficient systems. Looking at TCO factors like capital expenditures and operational expenditures is important for understanding the long-term costs of data center design and equipment selection.

5. 96.5%
a tco evaluation of the OpEx costs of operating
a ups over 10 years creates an operational
savings of $1.4 million when energy eYciency
improves a single percent − from 93 to 94
percent eYciency. With newer ups technologies
that oVer up to 96.5 percent eYciency, that
savings jumps to almost $3.4 million.
Therefore, a one percent gain in energy
eYciency matters.

OpEx CapEx
Total cost of ownership (tco), the sum of capital expenditures
(CapEx) and operational expenditures (OpEx), is a critical
metric to understanding true and long-term costs when
designing a new facility or selecting equipment. Yet with the
explosion of data center expansion, identifying tco variables
when specifying, building and operating a data center may be
more elusive, costing companies millions of dollars every year.
