I know this is not exactly the same, but ...
I live in Ohio and my shop building is insulated and sheetrocked but no heating system.
It's a 30X60 building, partially built into a hill so the back wall has about 7' of dirt behind it.
Coldest I've seen in the shop is 36 degrees so far. The floor and back wall put a surprising
amount of "heat" in the building. At least, enough to offset the heat loss. I will admit that
our winter has been both mild and stupid. We've only had a few days below 20 degrees and
we've had lots of days in the upper 20's and a even a few in the mid 30's. It may help that
the two overhead doors face South so on sunny days I actually get a little heat through
the doors; even though they are insulated I think they are only like R6 or something.
