An organization is selecting a geographic location for a new cloud data center. To reduce the electricity required for ongoing cooling, which site characteristic would BEST support this goal?
A tropical region at high elevation with average temperatures above 30 °C.
A hot desert climate that depends on evaporative cooling towers.
A region that experiences consistently low ambient temperatures and allows extended periods of free cooling.
A humid coastal area where chilled-water systems run year-round.
Locating the facility in an area with consistently low ambient temperatures enables long periods of free cooling-bringing outside air directly into the data hall or running dry coolers instead of energy-intensive chillers. Colder climates therefore lower power usage effectiveness (PUE) and overall operating costs. Warm, humid, or arid regions typically require chilled-water or evaporative systems that increase both energy and water consumption, making them less efficient for cooling.
