[Cob] thermal mass, insulation and "Ianto says"

[Buckaroo Bonzai]

The only exception to Shannon's statement is a home
which uses thermal mass which has been designed to
provide a six month lag time.  The techniques are
commonly referred to as passive annual heating system
or  annual geothermal systems.

Additionally though not cob, the ancient near artic
tribes used dug out rooms with bermed over roofs,
during the winter.  I presume they had a fire going
inside, but , maybe a family huddled close together
under layers of furs kept them warm when no fire was
available.

Cheers
