This is mistaken logic.
You may get more space per btu, but if you don't need the space, why bother
wasting the energy to condition it?
The ultimate goal is to reduce absolute energy usage. To do so, you want the
smallest, most efficient structure (fridge, house, etc). If a 15 cubic ft.
fridge serves your needs, use it instead of the 25 cu. ft. model unless the
total energy used by the 25 is less than that used by the 15, you're better
off with the 15.
Basement is the same. If it's not a living space, let it float to ambient
ground temperature and insulate it off from the rest of the house.
