This one's for the creative folks. I'm in a condo on the top floor and I have a side neighbor. Both our furnaces exhaust out the back, a four-foot roof section overhang (sticks out about a foot with a gutter). They're really close to each other (2-3 ft away) and our bedroom windows (3 ft down and maybe 3 ft. to the side). Here's my issue: The wind almost constantly blows a west to east direction there, creating a wind tunnel and always blowing the other and my exhaust past my windows – I’d say 90% of the time they are gusting past my condo.

Is there a way to create a wind break, possibly by placing some barrier, plexi or something, vertically under that eave and down between the exhausts to lessen the down draft of these furnaces? Thanks in advance. (Mine is on your left.)

I am open to other ideas too, besides a windbreak. Thanks.
