No yeast that I know of will work under about 57 degrees, and even that's pushing it. Unless you use a lager yeast, and ferment it at 50 degrees. The problem is that you don't want wide swings of temperature variations. You'd be better off at 62 and keep it there, or even 75 and keep it there but not those temperature swings from outdoors. Stick it in a closet and it'll keep the odor down.
