The natural airflow and the hollow micro-silicate insulation paint (providing an effective r20 insulation value) will make this much more comfortable in warmer and wetter climates. Where I'm building this one in FL, I will be adding a split AC unit and a BTC space heater that I expect to be all the additional climate I will need.
For colder climates, the steel provides a curtain wall that can be filled in with whatever you have available, hempcrete, cordwood, cob, or super adobe will all perform better than drywall and siding. The dome is essentially just 5 large pentagons, that can be prefabricated with aircrete. I've found foam-crete (w/re-pelletized styrofoam as aggregate) to be easier to work with. I can easily use the latex cement canvas on both sides, making the framing as thick as I choose, to prefab custom pentagonal structural insulation panels, or square/rectangular, as needed.
