Digital Edge explains WUE and data center cooling tradeoffs

Digital Edge has published an explanatory article on WUE, PUE, and cooling design for data centers.

• The piece explains how water usage effectiveness (WUE) is calculated, how it differs from PUE, and how cooling technologies such as air-cooled chillers, hybrid towers, open cooling towers, and liquid cooling affect water and energy use.
• It cites Digital Edge facility figures including SEL5 in Ansan with an annualized PUE below 1.25, NARRA1 in Manila with designed PUE 1.24 and WUE 1.082, EDGE2 in Jakarta with designed PUE 1.25 and WUE 1.082, CGK Campus in Indonesia with annualized PUE 1.25, BKK Campus in Thailand using hybrid closed-loop cooling towers, and Navi Mumbai with 10 million liters per day of recycled greywater and a WUE below 1.75.
