as standard office spaces. With such large power consumption, they are prime targets for energy efficient design measures that can save money and reduce electricity use. However, the critical nature of data center loads means that efficiency must compete with many other design criteria -- chiefly reliability and high power density capacity. The most efficient and effective data center designs use relatively new design fundamentals to create the required high energy density, high reliability environment. Emerging best practices capture many of the new 'standard' approaches used as a starting point by successful and efficient data centers.

of many hi-tech industries but a consequence of their
rapid increase in capacity is greater consumption of energy and
resources, and increased greenhouse gas emissions.

or it may be old and
inefficient. Either way, the electricity used in the building
will likely be produced with inherent inefficiencies. The
efficiency of fossil fuel based electricity production averages 34%
(although new combined cycle plants can exceed 50% efficiency). The
ultimate efficiency of any building pulling electricity from the
grid is limited by that number.
