<p>Another thing to consider…if the roommate really keeps his room at freezing temps, the cold will actually affect the amount of energy it takes to heat adjacent rooms. Is he willing to pick up the difference? In other words, if roommates room is 45 degrees, it’s going to take more to hear adjacent areas to 65. And every time roommate opens his door, a blast of cold air will permeate the rest of the apartment. </p>
<p>Also, I’m guessing roommate expects that the bathrooms will be a tad warmer!</p>
