It seems like the commonalities of open air design is to have open space on the front side mainly—i guess to maximize ventilation and minimize drafts.
Main gist is you want to try and aim any solid wall(s) towards predominant wind direction(s) - the idea is having the walls blunt the winds.
Even in my shed-coop I kept this in mind, as I have 5 windows on 3 sides of the coop without a big roof overhang or awnings and in 99% of weather conditions I can leave them all open with worry.
