Federal auditors have said the Internal Revenue Service could save more than US$3 million over four years by improving air cooling circulation at two data centres. However, IRS officials said that savings estimate may be inflated because it does not take into account the cost of implementing the improvements at the centres in Memphis and Martinsburg.
Data centres can be more than 40 times as energy intensive as conventional office buildings because of the high power requirements for the computers and the equipment used to cool them. Although the IRS has some environmental management policies in place for its 11 data centres, it has not dealt with energy efficiency, according to the report released today from the Treasury Inspector General for Tax Administration (TIGTA).
