A bit of information, but first a recap. In the
last 25 years, (2004) there has been an increase in temperature conditioning by
connecting the structure to ground heat.
1) Geoexchange heat pumps are well known. For more,
try http://www.geoexchange.org
2) The first passive annual heat storage house is
25 years old. Built in Montana, it varies from 66 to 74 degrees Fahrenheit with
no purchased power. For more, try http://earthshelters.com
3) Underground heat exchange system has been
conditioning greenhouses for 22 years. For more, try http://www.sunnyjohn.com
4) Annualized Geo Solar is an active version of the
PAHS system, with several improvements. For more, try http://mysite.verizon.net/res086ck/selfheatinhouses/
or search for ("self heating" AND houses).
At the last site, there is mention made of a finite
element analysis program for AGS design. Presumably it could also be helpful for
the other three techniques also. Someone working in this field might want to
contact the author, and ask him to give BLDG-SIM a short summary.
PS There are three other known techniques for
conditioning a building without petroleum.
