Free cooling in the UK

Exploiting free cooling in the UK through application of research and development


To evaluate the feasibility of retrofitting free cooling to a high resilience legacy design.


Evaluating meteorological data, a model was created to review different design options. Once the most favourable option was decided upon, OI continued their involvement through the installation and handover phases.

Result – £1 million/year saving

Significant operating cost savings, around £1 million per year, an exceptional result for a legacy data centre.
