Sustainable data centres help mitigate climate change
At Tieto, energy effectiveness has always played a central role to help mitigate climate change. We started to explore recycling of excess heat from data centre servers already in the 1970’s. Our new-generation data centre in Espoo has been connected to the local district heating network since 2011. In 2015, it was feeding back excess heat from data centre servers corresponding to 57% of the total energy use in the data centre.
“Minimizing environmental impact is one of Tieto’s sustainability objectives. In 2015, our energy recycling solutions helped reduce Tieto’s reported CO2 emissions by 2 373 tons,” says Christoph Lindemann, Head of Infrastructure Foundation Services, Technology Solutions & Modernization. “Based on our data centre strategy we are continuously replacing old data centres with more energy efficient alternatives, increasing server virtualization rates and utilizing smarter cooling solutions. In two of our data centres we are recycling excess heat from data centre servers to warm up nearby buildings. We believe this is the best way to enhance the energy efficiency of our data centres.”
