Thinking about a semi-permanent Yurt... In Texas

Is there anyone out there who has lived in a Yurt during a hot and humid Texas summer?  How do-able is this?  If we install a window unit A/C system, what kind of temperature can we expect to be able to maintain inside the Yurt during the heat of the day?  

Is the Yurt big enough to turn the floor into a hole a little deeper than a human height?
Maybe a thin cover layer on the hole?

Then the the cold air would be trapped in the hole …

I see this is a three year old thread - but wondering if you all ever did your yurt in Texas? I've got one and keeping it cool is a challenge! The young couple who built it had one "room" insulated with a small window unit but all it did was keep it dry/not humid and about 85F.  I've since moved the room away from the window and made it the bathroom.

I'm trying to figure out how to erect some sort of a shade structure that can be raised and lowered like a sail/flag to shade the house during the hot months, not cover the solar panels, and not blow over or take off up to OK.

Shade cloth perhaps is my best bet, but the poles would need to be so tall, they'd need to be dug super deep and cemented in I would think.

so just wondering if you all ever did this and how you managed to shade it if you didn't have the luck of old oak trees nearby.
