Nigel, the earthen walls would sweat the water vapor out in the daytime cooling the house. And collect it in the evening from inside again cooling the house. This has been measured to be about a 12 degree F difference in the Summer, between the inside and the outside without any fan or other air-conditioning. nigella1 wrote: > > Steve wrote:On the other hand, Texas, Oklahoma or whatever hot and humid > places are > different.

A green roof, even of a few inches would be perform better( and be fire resistent compared to shingles). Still put insulation in between. The transpiration of the plants would help in the summer. > cross ventilation, porches, high ceilings. > Shade. All that. > Dome shaped ceilings I've read don't get as hot as flatter roofs and radiate heat out faster in the evening. Anybody have an easy way to build domes, vaults, or arches? Darel
