How to ventatlate a bed room? No Holes in the wall!

  1. I'm going to be using a small room for my area, maybe a bedroom or a bathroom or something like that. I won't be able to rip anything apart or anything like that for ventatlation... what can I do? Is it possible to somehow use windows even though they would have to be covered to block light? Any ideas?

    Do you have access to a crawl space?
  3. take a piece of styrofoam insulation nd paint it black, then cut it to the size of the window, then make the hole and cover the hole with a VERY thin sheet of black fabric, and whala!
