The building’s desert location was carefully selected to take advantage of cool, dry nights which allow for mostly passive cooling – no ducts, no refrigerated air, no internal plumbing. In the summer humidity and evaporative cooling are added by misters and fans which pull the chilled air through a series of washable mesh filters. Engineering firm Alfatech led the innovative building design which was matched by an equally inventive power distribution system, dreamt up by lead engineer Jay Park, which eliminated a huge amount of energy waste through a single transformer. Typically in data centers there is an 11-17% energy loss between the power grid and the conversion to uninterrupted current. The Prineville data center limits energy transmission loss to 2%.
