Hot and cold: new approaches to heat management
Facebook is the latest technology company to announce plans for an Arctic datacenter. Specifically, Facebook will build a datacenter in Lulea (Sweden), which is just south of the Arctic Circle where the average low in January is 3 degrees Fahrenheit. This will be Facebook’s first non-USA datacenter and it’s scheduled to open by 2012.
Iceland, which is conveniently located between North America and Europe, is hoping that electricity from renewable resources can power the data servers that make the Internet work.
In addition, ZDNet’s Back Office blog has recently profiled Iceland, where a cool temperate climate means that it’s not so cold that a huge amount of humidification is needed for a datacenter but where its also cool enough so that fresh-air cooling can be used throughout the year. In other words, IT may have Silicon Valley but Iceland is the “silicon geyser” for datacenters.
Silicon.com also has a photo gallery of Verne Global’s datacenter campus in Keflavik (Iceland) – just outside the Arctic Circle. Iceland’s cold climate helps to keep the datacenter cool while the country’s geothermal and hydroelectric energy provides a clean and renewable power supply.
Disneyland Paris is partnering with French energy provider Dalkia to turn waste heat from its datacenters into heating and hot water at a business park. Eventually, the district-wide heating network will supply green energy to buildings with a surface area of 600,000 square metres.
Defense and aerospace company Raytheon has found that raising datacenter temperatures can cut energy usage by as much as 30%. Moreover, Raytheon has been building up its cloud computing capabilities, which has also led to a reduction in hardware requirements and energy needs, plus the company has replaced older equipment with newer and more energy-efficient models.
