No, that is 'space utilization'. Nothing to do with energy efficiency, which includes external energy absorption, as well as dissipation.
(And if energy were being solely generated inside, wouldn't a sphere have the best surface area / volume ratio, and thus the lowest radiating area versus internal volume?)
But my point is this: suggesting that for road cars 'drag is directly related to fineness-ratio' (the original Aerohead statement) is unbelievably* simplistic.
We can try to apply such a concept (ie just a dimensional ratio) to houses as well - except of course, in the real world, we can't.
* Yes, unbelievably. In more than 20 years of following web discussion groups, Aerohead is so far my Number One pick for a pseudo-expert disseminating (largely) rubbish. And boy, have I ever seen some doozies.
