For the last five years, data center owners and operators across the globe have been very focused on improving the energy efficiency of our data center power and cooling systems and reducing PUE. As a result of that focus, just about every realistic power and cooling efficiency solution has become commonplace in the design of our newer facilities. Aisle containment, elevated supply air temperatures, outside air economizers, VFDs, and energy-efficient transformers and UPS systems are nearly always specified in our designs. PUEs of 1.3 and below are now consistently achieved, even for highly redundant facilities in the most hot and humid regions of the country, and a 1.15 is often our target in cooler and dryer climates.
