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.

Seeking an air-to-water heat pump

I'm looking for an air-to-water heat pump and feedback from those who've used them. We have a LEED for Homes project in Victoria, BC, perfect climate for heat pump, affordability of project prohibits groundsource for 36Kbtu heat loss of 1800 ft2 home and for optimal comfort, low temp/efficiency, to avoid ducting we're selected hydronic in-slab for heating distribution thus standard air-to-air heat pump is a no-go.

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.

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?

Can rigid foam insulation have an air space between it and rim joist?

I am insulating my rim joists with 2" rigid foam board. Most of the rim joist is bare, and the foam fits along it nicely. Some sill boxes have some small irregularities (vent pipes, plumbing, etc) that I have worked around easily enough.

Round window flashing and water management

I have a situation with a remodel on a 1970's house with one round window that was replaced. The new window is installed, and the company had me replace siding and trim around the window. The window is an aluminum clad round (well, round with a flat section at the bottom, roughly 4" above where the siding stops).

We started out by installing sheathing on the wall- it had been built with no sheathing- it's a complicated wall with two round windows, and there are custom steel brackets holding everything in place (sort of).

Any Good thoughts on Drolet wood stoves?

A relative is asking about efficient wood burning stoves. Any thoughts. I would never burn wood outside an occasional campfire using up leftover 2x4 cut offs. I told him any Canadian company can't be all that bad and it the 2000 is EPA rated whatever that means...

Any recommendations would be greatly appreciated.

Thanks,
PK

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.

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.

Home energy monitoring programs

I am building a net zero energy home to Passive House standards in the Seattle area. In addition to having it be as efficient as possible, my goals were to use renewable materials (no foam), eliminate thermal bridging. have a protected air-barrier and to keep the OSB warm. I'm using dense packed cellulose in the R-50 walls and R-85 roof (cathedral ceiling with parallel chord trusses). The wall assembly is a double stud system with an inner 2x6 load bearing wall and an outer 2x4 wall.
