Conclusion
This approach's value lies in creating improved
consistency across multiple aspects of data center
design, construction, operation and evaluation. It
would assist manufacturers to educate stakeholders
with a standardized formula for true comparisons and
would simplify analyzing subcomponents in strict 1:1
comparisons.
Consultants regularly use these concepts when analyzing
systems for owners, operators and industry partners.
However, the typical approach when evaluating one
system or another is to look at every basis of design component
as it would be installed in the field regardless of
its impact to the decision at hand, e.g., when evaluating
various mechanical infrastructure concepts, consultants
typically don't look at them in isolation even if it is the
only aspect open for consideration. This gives a good
picture of expected overall facility efficiency, but doesn't
factor in the necessary task of comparing mechanical
systems.
Such a prescriptive measure would streamline comparison
exercises. Reducing time to make decisions
in the conceptual phase of a facility design can be
crucial in meeting aggressive design schedules. This
method would also make it easier to approximate
pPUE when examining an existing mixed-use facility.
Regardless of how PUE is leveraged, it is beneficial
to the industry. It encourages competition and pushes
the industry to strive for better, more efficient facilities.
It gives operators a metric to target when observing
the day-to-day functions of the infrastructure they
oversee. PUE's effect pushes the data center industry
to be more energy conscious. The tools and methods
proposed here will permit industry and non-industry
professionals to easily compare systems and components
within the data centers. Use and development of
the tools and methods would serve to better equip the
industry to communicate within and outside the data
center community.
