[Greenbuilding] Heat pump vs radiant

I would be tempted to model a hybrid to see which combinations would work
best for the space. You need an air system in any event so something that
has the potential of conditioning that air makes sense. Radiant can require
less power and is easily integrated into the materials and structure of an
earthship. 

 

I work in a rural context and am not a huge fan of geothermal installations
as they have become somewhat fashionable and often are done poorly or
invasively at considerable expense. It depends on what other aspects of the
land are being developed (roadways, wells, etc.).  Considering the earthwork
required for an earthship integrating geothermal is definitely something to
consider. Rurally its about how heavy the footprint is (always keep Thoreau
handy as a harpy on your shoulder).

This is a typical tire packed earthship. I am looking to implement Passive
House methods and see where we end up. I'd like to use as much salvaged
materials as well of course. 

I guess my question is not so related to an Earthship though. It is more one
of using solar thermal radiant or Minisplit PV. 

Matt you raise an excellent point about humidity. For that reason alone it
may be worth going with Minisplits.

The larger question is what is a better use of money for an East Coast
building with land, solar thermal, PV or geothermal....?

GBC--are you talking about a Taos style, a la Michael Reynolds, adobe packed
tire structure Earthship?  or is there some east coast variant...or is this
your own concoction?

Hello,

I am building an Earthship for a client in NY and he wants it bigger than is
ideal for an earthship, thus it will need supplemental heating and cooling.

 

My question is whether I should heat the space with radiant heating or with
a minisplit. Either system will be fueled by panels (thermal and PV).
