This reads like an add. Keep in mind you would have to cut down all trees in a huge radius. Not live on a mountain side. And the house doesn't have a furnace but it does have a heat pump. Like almost all new construction. This really just seems like a modern construction home with a few improvements tacked on to make it slightly more efficient. However I wonder if the gains from doing this offset the utility costs at all. It cant be cheap to build 15" thick walls.

Even the article states this is best for appartment buildings and condos.
