The opening is to the east and a touch north. Most of our wind and snow comes from the southwest and northwest. I have notices that the snow builds up only from the back and side of the structure. They will still have the sunshine from the roof (when i brush the snow off) and still get fresh air from the open side. I put bales of straw on the south side along the lattice to stop any snow from coming in too.
I have solid sheets of the roofing stuff, so I am thinking in the summer i can put that on and remove the straw for a shaded cooler area.
what's next? built in air conditioner???????
NOT!!!!!!!!!!!!!!
Although DH friend tried to give us a window one last year and DH put his foot down on that one.
