Use of Underground Spaces for Resource-Efficient Data Centres: A Case Study of Helsinki, Finland

Increasing use of the internet, cloud services, and online storage of vast amounts of data and information have amplified the need for data centres across the world. These centres are energy-intensive and require cooling around the clock. With the case example of Helsinki, Finland, the paper highlights the value of embedding principles of circularity and resource efficiency in the design, construction, operation, and maintenance of underground data centres to reduce emissions, consumption of resources, and costs of energy.
