Default Planning new house

Closing July 29, 2016 on sale of current house.

Planning next build:
8,800' altitude, zone 5b (dry) Teller County 10 miles West of Pikes Peak.

IMO at high Colorado altitude there is no need for A/C, in Summer open windows at night is all that's needed.

Will design slab radiant floor heating system for 0*F
Slab will have 4" of type 2 EPS under & vapor barrier, drainage & Radon venting.

New house will be a simple to build rectangle with a steep 12/12 pitch metal roof.

Main level will be a walk-out basement to the East, 8" concrete walls.
Great room kitchen in front 1/2 & master bedroom & mechanical room in rear 1/2

The upstairs framing will use attic truss, I have used these twice before & think that they a very cost effective way to get upstairs rooms. There will be a bedroom in each end and a bathroom & stairs in the middle.

The upstairs front (East) will have a large balcony that also serves as shelter for parking under by front door.

For the main level the concrete exterior walls will be stucco. Inside next will be 3" polyiso foam (R-16.8 this is the latest aged value) that I bought cheap on Craigslist. Then 2x4 stud walls with R-15 Roxul Rock wool, then sheet rock, no vapor barrier.

Upstairs the only exterior walls are the gable ends. The outside will be James Hardie lap cement siding on vertical 1x4 Cedar nailers over 30# felt over OSB with taped seams. The insulation will be the same as the main level.

As there are big pine trees close on neighbors lot, fire risk must be considered.

So I am looking for input on a couple of things:

How to keep forest fire embers out of soffit & ridge vents?

I plan to mount the main level Windows on the inner 4" of the 8" concrete wall, water control is my question? Flashing out past window would look bad.
