"Energy Efficiency Guide: Data Center Temperature"
 March 10th, 2011

  "Most data centers operate in a temperature range between 68 and
   72 degrees Fahrenheit, and some are as cold as 55 degrees. Raising
   the baseline temperature inside the data center - known as a set
   point - can save money by reducing the amount of energy used for
   air conditioning. It’s been estimated that data center managers
   can save 4 percent in energy costs for every degree of upward
   change in the set point. The list of companies singing the praises
   of savings through higher baseline temperature settings in the data
   center includes Google, Intel, Sun and HP."

  "But nudging the thermostat higher may also allow less time to recover
   from a cooling failure, and is only appropriate for companies with
   a strong understanding of the cooling conditions in their facility."
