How do I open a window from the outside?

How much energy do you lose having a window open 3 inches when there's a 20 degrees difference outside?

  • my roomate is an idiot and doesn't think leaving his window open wastes electricity. apparently he never was taught the 2nd law of thermodynamics. I'm trying to figure out how much energy he wastes leaving his window open 3-4 inches when it's 20, 30, or 40 degrees colder outside.
