Help with Green Addition and hyrdonic heat demo

I am in the process of designing a pretty substantial addition onto my home in central Missouri. I understand that our relatively low electricity costs will not be around in the next 5-10 years in the US and am planning for this.

Proper wall to attach rigid foam to the inside of the wall?

Question: what is the best way to attach rigid foam (foil faced polyiso) board to the inside of a finished wall? Can I just use longer drywall screws to go through the 1" foam and existing drywall? What if I'm going with more than that (say 2 or 3 inches of polyiso)? I'm worried that this method would have a greater tendency to pop the drywall screws out under small impacts like hanging a picture. I'm also worried that the walls will sound hollow or be bouncy when knocking on them. What are the best practices for each thickness of foam?

Detail for stone veneer

I am looking for a wall framing detail that includes a stone veneer face over 1" ridged insulation. It seems to me that after a rain screen detail over the rigid, the next surface would be OSB or plywood that metal lath would be adhered for applying the stone veneer? So the assembly would be 2x6 stud wall, OSB, WRB, 1" ridged insulation, rain screen (lath, Coravent, etc), 1/2" plywood, metal lath, stone veneer.

Does radiant heat recycle water

With regular radiant heating systems that use warm/hot water to run through tubes in the floor to heat the home, what happens to this water - does it get recycled through the system, heated up again, or does it go down a drain?

Polyiso on interior

Martin/Dana

Living in the Bellingham area north of Seattle it can get cold. The house was heated by propane, it was a cost that was hard to get hold of especially with some of the design of the house. (high ceiling)

I set out to improve the insulation of the home taking bits and pieces off the internet as to the techniques available these days.

I am a bit "OCD" now that the living room is for the most part done "I have some hidden inward worries". I wonder if I am trapping moisture inside my walls having used the foilfaced polyiso just behind the sheetrock.

Mid Roof Edge Vents / Ice Dams

I'm located in Michigan and in the process of putting on a new roof and want to address some issues relative to poor ventilation and ice dams. Overall, the attic is well insulated, but because of the roof design the hip roof in the center has almost no air intake. My plan was to address this using mid roof edge vents.

Designing a passive solar / net zero house in NC Mountains

My wife and I are designing a new mountain home in Banner Elk, NC. We are in the initial design stages with our architect and are confused by the numerous options to consider. Our house will be built in the Eagles Nest community which has a pacific northwest lodge feel. Our home site is at a 5,000 foot elevation on the mountain ridge with a northern view.

Choosing Insulation for a Cathedral Ceiling

This is my situation: I am located in colorado, where is is generally dry, gets hot in the summer and cold in the winter. I am in process of building my own house and want to make choices that wont come back to bite me down the road. With that in mind I want to avoid any moisture issues inside my ceiling cavities. What I have so far is a stick framed cathedral ceiling using 2x12 dimensional lumber. On top of the rafters I installed 1/2" CDX sheathing and covered that with grace tri-flex (I wish I had used felt paper).

Plumbing vents exiting ridge cap

Can't seem to find anything in the code, easily missed though. I have a customer who wants a metal roof installed however they have had bad experiences with pipe flashings through the roof and don't like the look of them. While I don't care for the pipe boots, (for metal roofing), appearance they seem to work well.

Anyway, to the question... Is there anything code or common sense wise that says vents couldn't go through the ridge cap? I know it wouldn't look as good but, would limit water flowing over them.
