Warming Helsinki with Data Centers

::: nBlog :::

Our favorite IT provider Academica is now constructing the world’s first Data Center with a full heat recovery system, in close cooperation with Helsinki Energy. In other words, warmth from the servers and other equipment is not exhausted away but transferred to Helsinki Energy’s district heating network. According to our initial calculations, once fully equipped the data center is able to heat some 120 households in wintertime. During summer with low heating needs, sea water is used as an auxiliary cooling source.

Energy consumption of each rack in the data center is measured with sub-minute intervals. Customers will only pay for the energy they consume, and may also decide which type of energy they’d like to support – Wind, Nuclear, Fossil etc, just like households are nowadays able to do.

As far as we know, this is also the first Data Center in which it instantly pays off for customers to utilize servers with low power consumption. Customers with existing servers may also radically lower their overall consumption by adjusting the servers’ power usage according to natural usage patterns – most retail systems are idling during nighttime, for instance.

The data center will be operational still during this year. I’m sure to be posting measurements as they’re implemented. This will also be the world’s most measured data center, not least because we’ll locate one of our Nordic BaseN Platform node groups there.
