‘Efficiency’ may be the wrong word for it, but Paul’s formula accurately describes what you might call the ‘infiltration tax’ for a energy-conserving/entropy-ignoring model: when you pump out heat proportional to (exhaust—indoor), heat proportional to (outdoor—indoor) infiltrates back in.

That’s an important argument, thank you.
