This building was not using a blower door. However, the room must be depressurized because the air is coming in at the top of the room.

Thanks for the comments.
Unfortunately, I can not get access to the attic to verify the reason for the infiltration.
I believe the right side of the roof is down wind and showing the effect of wind coming in through the ridge vent.
The ceiling is showing cold where the fiberglass is not sealed at the top plate. I don't believe there is a poly moisture barrier on the inside wall.
