WELL IF YOU HAVE A TRADITIONAL YURT YOU JUST OPEN THE SMOKE HOLE AND RAISE THE CANVUS A LITTLE ON THE WALL AND IT WILL COOL IT SELF SOME WHAT.BUT IF YOU ARE TALKING COOL COOL THE YOU NEED THE AC.

Hi Delia. We live in a yurt in New Mexico. Get sa bit warm but our fix for cooling was to cut floor vents (4) to draw cool from under our yurt. We also experimented with the insulation. Rather than put the insulation above the rafters we at first stapled the material to the inside of the rafters. What this did was created a open air space allowing for better air flow. This has worked great for eliminating the condensation as well.

A few weeks ago we cut our insulation into sections that fit between the rafters and hung fabric creating a bellow that holds the fabric and insulation in place. We left a gap of 6" top and bottom to allow the air to move. It worked better than we thought. In fact it moves enough air to blow a match out at the bottom near the walls. We're hoping that this will work the same this summer. Plus leaving the top open a bit should create a natural air flow venting the hot air to the top. I'll try to post a pict. Good Yurting:-)

ps... the vents also work good in the winter to allow additional air flow fo the wood stove. Google Search in video. "Yurt how to" 5 parts. Cheers again......
