Cooling Practices Adapt to Water Efficiency Goals

In the early 2000s, energy efficiency stood as the dominant force shaping equipment selection and facility design. During this era, open cooling towers were widely adopted as the primary method for heat rejection, valued for their effectiveness and relative simplicity. In the data center space, power usage effectiveness (PUE) quickly became the industry’s foundational metric, guiding decisions aimed at reducing the amount of energy consumed by supporting systems relative to computing workloads. This metric-driven approach led organizations to invest heavily in technologies minimizing electrical consumption while ensuring high-performance operation.
