There are a couple other ideas for solar heating.  Check out the soap bubble
insulated green house in operation in Canada.
http://www.tdc.ca/bubblegreenhouse.htm
Heat gained is stored in insulated water tanks under beds in greenhouse and
insulated at night by soap bubbles between inflated greenhouse poly at
night.  It has been incredibly successful.

Frank Lloyd Wright utilized rubble trench foundations and a grade beam.  The
rubble trench drains soils below the grade beam to prevent freezing and
frost heaving.  I believe he got the idea from the Hopi Indians.  I have
used this concept on a couple buildings and found that it worked very well
and continues to do so here in Alaska after over 20 years.
This may not be as efficient as PAHS but with insulated footers, slabs, and
perimeter Apron, it is very efficient and relatively inexpensive.

I'm not suggesting this is what is needed, but these principles may be
helpful and or combined with other techniques.

Building a large greenhouse over the building site with residence enclosed
and built under protection has great potential in cold climates offering a
myriad of advantages.
