    Mark, I am curious about the wall framing. Did you consider 2 x 6 framed at 24"o.c?

    Typical of what is essentially a "Government" program. With ANSI Std: ICC-700-2008 available through the NAHB reseidential program, why even pursue a LEED-H rating? NAHB program encourages ...

    Tobias, When faced with a limited depth as you are, I generally prefer to fill the bay with dense-pack cellulose. A properly vented roof is desireable, but when it means the difference between ...

    Very nice David. I have to admit that even the "windmill" looks good.
  • Martin Holladay | Mar 23,2009 10:08 AM EDT
    Stephen, Many researchers have built combination solar collectors over the years — that is, units integrating PV with solar thermal collection. While these have some advantages — obviously, the ...

    I take that partially back. the Dawn System is like a radiant system but it installs above the roof deck between sleepers like a radiant floor and then you can install metal roofing or solar PV ...

    Dan, Try this....start a pencil line at the top of the 3/4" furring strip/drainage channel...draw a continuous line down along the drainage channel until it finds its way to the outside.(if you can)

    Mark, I have one other question. What was the construction cost or what would be the selling price of the home not including the land? How does it compare to a similarly sized conventional house?
  • Kevin Korn | Mar 21,2009 11:12 PM EDT
    Mark, Did you consider other types of wall systems like a Larsen Truss and if you did, why did you select the method you used? I like the concept of the complete envelope formed by the exterior ...
