The material costs for adobe are almost certainly close to zero if you live in an area that can benefit from using it. The labor costs for adobe have become very high, mostly it seems because the descendants of the families that started the amazing adobe brick "factories" no longer want to be dirt farmers. > can probably beat thermal mass construction. You have to define what "beat" means. My hundred year old adobe did not rise above 81F as an interior temperature this summer, despite outside highs around 100F. That would be possible (or even lower!) with the technologies you mentioned, but my adobe house did that with no energy utilization at all.
