Ground source heat pump
A ground source heat pump (GSHP) is a geothermal option for heating and cooling.
Basic principle: Use the temperature of the ground a few hundred meters deep. This is a very stable 16'C
Environmental & labor footprint of construction
This section needs research:
- How easy is it to retrofit existing buildings?
- Single-detatched homes
- Townhouses, mid-rise and high-rise buildings
- Warehouses and other
- How does this viability compare with new construction?
- Life cycle analysis: How long does the thing last?
Energy usage
It still takes some electricity to run a GSHP. Also, in the winter, you'll still need some additional heating
Geography
Unlike other geothermal energy (which is only viable in a few parts of the world), ground source heat pumps work in almost any part of the world.
