How much warmer would a house be in winter if it was surrounded by

Once it is cheaper to superinsulate than buy oil, it will be done. That's the
wonder of markets.

The problem with the straw bales is that tehy have windows in them. And
venitilation.

I cant remember the EXAT calcs, but it was something like the fact that
to get the required ventilation reduced the effective insulation of my
house to a limiting U factor of about 0.15. Unless I somehow used the
outgoing warm air to heat the incoming colder...
