A little more mundane than B-movie-set data center deco.

_Abstract:_
Data centers greatly impact California=92s natural environment and=
economy. These buildings host computer equipment that provide=
the
massive computational power, data storage, and global networking=
that is
integral to modern information technology. The concentration of=
densely
packed computer equipment in data centers leads to power demands=
that
are much higher than those of a typical residence or commercial=
office
building. Data centers typically consume 15 times more energy=
per
square foot than a typical office building and, in some cases,=
may be
100 times more energy intensive (Greenberg et al. 2003). =
Nationally,
data centers consumed 61 Terawatt hours in 2006; equivalent to=
the
practical power generation of more than 10, 1 Gigawatt nuclear=
power
plants (Brown et al., 2007). This is approximately equal to=
annual
electricity consumption for the entire state of New Jersey (EIA,=
2006).
California has the largest data center market in the U.S.,=
indicating
that a significant portion of this energy is consumed within the=
State
(Mitchell-Jackson, 2001).
This research project focused on identifying how data centers are=
currently designed and exploring potential energy saving=
associated with
alternative building design options. The energy savings were=
quantified
to understand when design changes resulted in significant=
benefits and
when the benefits from alternative designs were minimal. The=
potential
energy savings benefits were juxtaposed against changes to the
environmental conditions in data centers and evaluated within the=
context of computer reliability concerns. The objective of this=
research is to provide data center designers and other decision=
makers
with a better understanding of the benefits and concerns=
associated with
data center energy efficiency, thereby reducing the unknown=
consequences
that may hinder attempts to shift away from conventional design=
practices.
