It’s been a pretty hot summer at times. Have you been tempted to crank the air conditioning to as low as it can possibly go?

Energy Star, a joint federal program run by the Department of Energy and the Environmental Protection Agency, have set recommendations for where your thermostat should be for ideal energy efficiency:

  • 78° F when you’re home
  • 85° F when you’re at work or away
  • 82° F when you’re sleeping

Does this seem a little extreme? Especially for those who like a cold room while they’re asleep! But according to Energy Star, you’ll save 3 percent on your utility bill for every degree you raise the thermostat.

They suggest if you’re not that heat tolerant just yet, experiment by raising the temperature up by one degree over a couple weeks until you’re used to a warmer home.
