Selecting a back-up heat source for a wood stove

We're planning on building a super-insulated, tight house (hopefully starting construction this fall). There will be about 2000 square feet of living space, all heated by a small wood stove. Between the passive solar we have designed and the available wood on our land, we expect this to be a very low-cost way of keeping warm. But, of course, the bank requires a thermostatically controlled source of heat. We expect this secondary heat to be used very rarely-- it's really just there to satisfy the bank-- so we'd like it to be as inexpensive and unobtrusive as possible.

Cool Shingles

I need a new roof and my home is located in Pittsburgh, PA. I was browsing the Owens-Corning website looking for a light, EnergyStar color when I stumbled upon their solar reflective "Cool Shingles". I have asked 6 roofers for an estimate and none of them have heard of them, nor are they interested in giving me an estimate on them. Two of the roofers tried to completely talk me out of them even though they admitted to not knowing much about them.

Diagonal Furring Strips.

Hi. I have been searching and searching for information regarding diagonal furring strips. I want to install siding vertically, and am avoiding horizontal installation of the furring strips. I've read that the diagonal strips should be 12 inches on center. Why is this and not the traditional 16 inches when installed vertically?

How do I estimate diagonal lumber sheathing amounts?

After drawing some sketches, it appears that I should add 15% to the square footage of my walls to allow for waste created by diagonal end cuts, and unusable short pieces.
Does this sound ok?

I'm sure there's some rule of thumb published in an old carpentry book out there...but I can't find anything.
