When wind blows along the side of building(outside), a very low pressure zone is created just outside the building. So air inside the room is at much higher pressure compared to air just outside the building. And air tries to move from the high pressure zone(inside) to low pressure zone(outside). Hence when the air tries to move from inside to outside, the broken panes and curtains move outward along the wind.
