Geo solar homes utilize energy from both the sun and earth for heating and cooling purposes. In these homes, solid wood walls substitute siding, framing, insulation, and paneling. Owing to this design, air flows around the building, creating a miniature biosphere. This air envelope is heated by the sun’s energy.
As the heated air circulates, geothermal energy is absorbed from beneath the house. The wood walls absorb and store energy, which creates a thermal inertia causing the house to maintain a comfortable temperature.
Geo solar homes are energy efficient due to the following aspects:
Solid wood construction
Using natural sources to generate energy
Turning the house into a heat pump
The role of the air envelope
The "floating" factor:
Geo solar homes work due to the ability of their walls to gain, hold, and release heat. This allows the home to double up as an energy storage facility. The walls experience thermal lag, which leads to “floating” where daytime energy stored offsets the energy used at night. Floating can go on for days at a time, keeping the house warm during days when the sun does not shine. Geo solar homes are known to float through extremes of heat and cold that would endanger occupants of other buildings.
