> I think this overall makes a good point that any type of directly heating people is much more efficient than heating an entire building.

It is, but if a building cools down below the dew point (and it will, unless you're somewhere near the equator), any humidity e.g. from the air you breathe out or from plants will just crash out and condense on the walls, resulting in mold.

Because of the effect you’re talking about, the outdoor dew point is never above the outdoor temperature- so the air even indoors gets really dry when it’s cold outside, and you only need to keep the inside slightly warmer to keep this from happening.

I am into sailing and often sail in cold climates without cabin heat- and find that my body heat alone is enough to prevent this from happening in a small sailboat cabin.
