"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."
