permaculture

[<scott@permaculture.org>]

The energy efficiency comes from the "flywheel effect" of bermed or buried 
structures from their interface with the surrounding earth.  Toxicity is an 
ongoing controversy with this technique and the justification used that a 
thick layer of plaster will protect the occupant is bogus.  Plaster breathes 
just as all good wall materials do other wise you wind up with walls that 
"sweat" with the interior moisture.  Plaster is porous and does nothing to 
mitigate out-gassing.
