NatHERS really likes concrete floors. If you don’t have a concrete slab, you will have a hard time getting your star rating. But this depends on at least two questionable assumptions.

Or to put it another way, NatHERS lets big houses off the hook. In two ways. Because small houses naturally have more surface area; and energy use limits are per square metre, not per house.
