My understanding is that clay straw mix, even heavy on the straw, is more of a conductor than an insulator. The purpose of this wall is to be super insulative, so pure straw it is. The whole thing will be covered in cob, which will seal out any air leaks, and the door is going to be something like 7 inches thick and packed with wool.

Is anybody living here for the winter?
Anybody keeping track of the temps etc?

Using my modeling skills, I have built a concept model to illustrate the simplicity of the concept.
I made these diagrams to help others visualize the concept.
This concept is scalable from small to large. Trombe walls are way more complicated than straw-bale, too. But they might have some advantages in digger designs with bigger budgets.

evan l pierce wrote:While integrating solar orientation into a wofati makes good sense, the wofati concept doesn't directly rely on it. Instead of necessarily aligning with the sun, a wofati is aligned with the hill. Drainage being of primary concern, wofatis have an uphill patio with drainage ditches that redirect water coming down the hill away and around the structure.

Having said that water flowing of a roof into a tank is an easy way to get drinking water and one that is used here in Oz a lot (our water never goes solid). As we face yet another drought it would be a major design consideration for me.
