Ah, weather – one of life’s multi-purpose tools. Conversation filler (“Quite the weather we’re having.”), alleged indicator of world’s end and source of inspiration for comic book writers to empower heroes and villains alike.
Weather can also be a Data Center’s best friend. Solar energy can be harvested to help generate power, for instance, such as is happening at Cisco’s Data Center in Allen, Texas. (Look for the 100 kW solar array on the right side of the Data Center’s roof.) Wind energy as well. Rainwater can even be collected for cooling system usage or to irrigate landscaping.
Perhaps most significantly, climate conditions rank among the top Data Center site selection criteria because you can build the same Data Center in different locations and each facility will consume different amounts of energy thanks to the weather. Cooler outside temperatures and economizer technology can significantly reduce a Data Center’s power consumption and therefore its operational costs.
How significantly? We’re estimating $600,000 in annual savings at our Allen Data Center thanks to an airside economizer and an agreeable climate.
Watch the video below for a quick discussion of airside economizer basics and a referral to online calculators for estimating the potential energy savings an economizer can provide depending upon a Data Center’s location.
