This is true. It appears some people are not familiar with the idea of passive heating and cooling or zero energy homes.

Let's not assume all or even majority of homes are zero energy. At least in Europe the vast majority are energy performance class F/G.

You can't rent or sell anything F or lower in my country, so I guess that'll change soon.

By 2030 everything should be at least E, by 2033 at least D and by 2050 all A.
