Some of the dome houses I've been in are almost self sustaining as far as heating/cooling goes. His walls are very thick, I noticed so I'd say minimal amounts to sustain it. But I don't know in Texas where he lives.ndog:
I've been wondering about the dome house ever since you first mentioned it.
1. What are the triangular pieces made of?
2. How can a space that size be heated on a cold day, or cooled on a hot day?
3. How long have you been working on it, and how close is it to completion?
4. Are you living in it now?
Are you going to create smaller, rectangular living spaces inside the dome? Like a bedroom? That would be one way of dealing with the heating/cooling issue.
