Recycling of surplus heat from data centres

We use free cooling in our data centres in Scandinavia. We have chosen to locate our data centres in Scandinavia partly for security reasons, but also because our climate automatically provides cooling that can be used in the data centres. Our newest and largest data centre located in Oslo is a good example of smart green IT. For most of the year, this data centre is cooled by nature. Excess heat can also be recycled for heating when necessary. Another good example is from one of our data centres in Stockholm, where we use energy for cooling from an energy company. The surplus heat in the data centre is then recycled in the form of hot water, which the energy company uses in its production of district heating.
