The Pawsey Centre case study

The Pawsey Centre uses an innovative geothermal solution to being used to cool the most advanced supercomputers in the Southern Hemisphere in place of cooling towers that rely on water.

Why we acted


Supercomputers consume large amounts of electrical power, almost all of which is turned into heat.

The CSIRO wanted to develop a solution that would be more sustainable than cooling towers which normally use millions of litres of water per year. An efficient and sustainable cooling system was fundamental to the facility's design.

Geothermal cooling was preferred due to the low environmental impact and because it is not affected by weather extremes or seasonal changes.
