A local Buddhist community (Iron Knot Ranch) here has used "rastra blocks" sold by a factory in Arizona to build their community. They are made with concrete and recycled industrial styrofoam and are sold as 8 ft long square logs. They have channels for pipes, wiring, as well as rebar and concrete to tie walls together. High R value and relatively inexpensive.
