Best orientation for the bedroom of the east, so the sun shines the space just after the rise. It makes the wake more comfortable and easier, and it's good to know that the sun's rays have an antibacterial effect if they penetrate deep into space. I'm setting up dorms east, summer time, the dormitory space arrives by evening to cool off and provides a more comfortable dream. More orientation are acceptable to be further south and southeast, while the western and clear northern orientation is to be avoided. The west side for the heat, and the north for insulating insulation.
