All Dark -- I'm materials agnostic. Pros and cons abound. I like paper/hempcrete but it's not fireproof. For that you want basalt fiber canvas. You could put that on metal standoffs on a wood inner shell and circulate air between the two.

A single layer, ventilated shell can maintain a 10 degree difference, add windpower and it gets better.

Passive solar heating has been okay,but our North Texas latent heat is really hard to bear without refrigerated air.Some nights the low temp. is 90-F,with a heat index of over 100.Ten years without AC probably took 20 off my lifespan.
I'm able to cool the house with 5,500 Btu/hour heat rejection.The electricity is rhetorically 'carbon-free'.
Presently,the local wind speed is very low,but it's blowing 20-mph in Amarillo wind farm,Texas.

The collaboration with Kaspersky Labs is interesting; they're the only antivirus company I trust. Colonizing the Artic is ontopic for the coming Ice Age.
