That&#x27;s...a lot of wood. This is all hardwood, seasonsed for a year? How large a piece of property would you need to sustainably re-grow that much wood indefinitely (wood growth rates in the Yukon are slower than in more temperate regions)?<p>What is the R-value and ACH [1] airtightness at 50 PA of such a house? I&#x27;ve been researching using two feet thickness of Pittsburgh Corning FOAMGLAS with an airtight building envelope that conforms to PassivHaus airtightness standards, and comparing the capital outlay of that with the anticipated opex cost savings. But I live in a far more mild climate than the Yukon, so my payoff period is measured in many decades.<p>[1] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Air_changes_per_hour" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Air_changes_per_hour</a>
