Data Center ASHRAE Prescriptive Cooling System Energy Efficiency

Google and its industry peers react to ASHRAE cooling standard for data centers. …

… “Unfortunately, the proposed ASHRAE standard is far too prescriptive. Instead of setting a required level of efficiency for the cooling system as a whole, the standard dictates which types of cooling methods must be used. For example, the standard requires data centers to use economizers — systems that use ambient air for cooling. In many cases, economizers are a great way to cool a data center (in fact, many of our companies’ data centers use them extensively), but simply requiring their use doesn’t guarantee an efficient system, and they may not be the best choice. Future cooling methods may achieve the same or better results without the use of economizers altogether. An efficiency standard should not prohibit such innovation. ” …

Efficient data center is recognized with rebate
Sacramento Municipal Utility District recognizes RagingWire’s efficiency efforts with a incentive rebate of $150,000. …

… “Some of the efforts include installing waterside economizers, oversized cooling towers, variable speed pumps, and highly efficient chillers. The result of this past year’s efforts alone have created additional energy savings of over 2,000,000 kWh of electricity per year, which equates to reducing 1.6 million pounds of CO2 emissions, or the equivalent of driving a small family car around the Earth over 100 times. These savings are incremental to RagingWire’s already environmentally friendly design. ” …
