I would think you'd want to alao take into consideration the fact that cold air falls and hot air rises. Given this, the cold air inflow into the yurt should come in up high so that you get maximum cooling. And since hot air rises, likewise the exhaust should be up high as well since that is where the hot air ends up. Of course, locating them on the walls would be the best to prevent rain problems/leaks etc. Though I could see a well sealed input being placed on the roof (but not the exhaust).
