Spending 5% of the government budget for ten years on measures that reduce energy consumption by 20-30% for a third of the housing stock forever is a bargain. The 20-30k figure was based on my experience with German houses, I have no idea how much it would cost for the typical old finish house to come up to standard. Based on the very few rural finish houses I've seen I would guess it is less, because they would probably tend to be smaller, but that is pure speculation. Also, of course it is worth investing 20k over 10 years into a 80k house in many circumstances. Why wouldn't it be? Yes, some people won't be able to afford this out of pocket (though I maintain that this group is smaller than you'd think). But again, the government could (and should) support this group, making it financially feasible.
