Lower Data Center power consumption through use of the climate characteristics of cold regions and inter-regional energy integration

In the achievement of sustainable society, the lower power consumption becomes a worldwide concern. Power consumption at the Data Center is a big share in the entire IT, and is still rapidly increasing. This research focuses on the air-conditioning that occupies the biggest electric power consumption at the Data Center, and proposes to develop the technique to lower the power consumption. We verify those effects by the experiment. Furthermore, we also examined which extent the energy reduction is possible when the Data Center is located and used in Hokkaido remotely from Tokyo region where many IT users in Japan exist.
