It's a pretty common sight around college campuses in cold-weather states: Snow is falling. Icicles are forming. Students are shivering as they shuffle to class in layers of clothing. And the dormitory windows are wide open.
That's right. Despite the chilly temperatures and biting winds, many students open their dorm windows to let in cool air. Why? Because, in many dormitories, it's the only option once a room overheats. For a university, it's also a pretty expensive option.
