I think you need to think about the entire design. One should not end up with an oven when building passively. There are many books out there that will help in deciding how much glazing you can get along with. Myself, we are building in NM with adobe. Using the walls and concrete flooring for the heatsinks, solar supported radiant floor heating as backup. Still in the planning stages, but this is the direction.

Hi bill.
Thanks for the input. do you have any 'good' books to recommend? There are so many, its hard to choose.
On this design, in theory anyway, it will be isolated heat wise from the rest of the structure.
Only when heat is desired will it have any influence on the inside temperature.
My goal is to create a heat sink large enough to basically heat the home by solar alone. (Not withstanding long periods of overcast weather of course). We have been lucky weather-wise here in New England over the last few years, but generally its pretty cold around here. Windy too!
It is the back wall that i need to insulate, while retaining its thermal mass.
Upon building a scale model, ( 1" = 1' ) i have tried a few changes, one of which would involve moving the collector out about 4'.
That too opens up other challenges. :-)
