Open doors and windows are considered to be completely absorptive (a=1) because all the sound waves continue traveling out the space instead of being reflective back into the room.
It should be noted that for the case of doors or windows opening into a space where another wall may reflect the sound (hallway, closet, etc.) then the absorption will be less than ideal, but still fairly significant.
