The US Environment Protection Agency (EPA) has officially launched the new Energy Star label for datacentres this week.
The opening follows years of development and will form an extension to the company's existing energy efficiency certification scheme by allowing cover for server farms as well as individual servers.
The scheme will require firms to measure the energy efficiency of their datacentres using a Power Usage Effectiveness metric. This gauge is designed to measure how much of the energy consumed by the datacentre is put towards useful work rather than wastage.
A licensed professional must then independently verify that the energy performance statistics to check that the claims are accurate.
Datacentres in the top 25 per cent of their peer group will earn the Energy Star label.
The EPA said the new scheme will encourage businesses to enhance the energy efficiency of datacentres. The company also cites recent government data which shows that improving data centre efficiency by10 per cent could cut energy bills by more than £31m a year.
Finally, EPA stated that datacentres remain one of the largest consumers of energy in the US, accounting for 1.5 per cent of total US electricity consumption.
