That looks a whole lot more relevant to the topicg.

Anything around the sides is going to make it a lot easier for the air
exhausting the top to get pulled back into the sides unless there is
some sort of additional barricade between the top and the sides, like
a big flat plate with a hole in the middle for the exhaust air, and
extending horizontally to the tops of the side panels.and the building.

I don't see that being the case to any large degree. I think the upward
flow sucks air horizontally.

It's not rocket science.
Put a thermometer on top in the exit path.
Obscure the sides to various degrees. *Cardboard works.
If the temperature goes up, it costs you money.
Just decide how much more you want to spend and obscure it that much.- Hide quoted text -
