Re: [papercreters] Re: underground papercrete house? How do I waterproof it?

Actually the earth is not an insulator, but is a great thermal mass.
Without insulation between you and the earth your inside temperature
will tend to be at the same temperature as the earth, which should be
stable at approximately the annual average temperature for your area. In
my area that would be 68 degrees and that is why I am building
underground. If there is a large difference between that annual average
and the temperature you want inside, you will have to invest a lot of
energy into heating and cooling. Thermal mass is equivalent to heat sink
in this case.
