Green I.T. Awards Finalist


We invest significant time and money in green initiatives to reduce our carbon footprint. So we were delighted to be named winner of the Green Datacentre Project of the Year category in the 2012 Datacentre Solutions Awards.

Our win was for our installation of one of the UK's first evaporative cooling systems - cutting our Surrey data centre's cooling load by 88.9% and saving an estimated 440,605Kg of CO2 a year.

We managed to reduce our actual Power Usage Effectiveness (PUE) to an incredible 1.14. Only a few other facilities are able to operate at 1.1-1.4, making 4D Surrey one of the greenest data centres in the UK.

(PUE is calculated by dividing the total amount of power a data centre consumes by the amount used by its IT equipment. A PUE score of around 2 for a data centre is average, while 1.5 is considered efficient. Anything below this is very difficult to achieve - which is why many data centres don't even try.)
