I don't think this is getting the coverage it needs. Scottish government to require passivhaus standard for all new build homes. This is big. Really big. Growing out of lessons from the 70's oil crisis. Passivhaus buildings use very little energy to heat, or to cool. We've known how to do this for decades. It's gross negligence from all western governments that the same is not true of all new builds in the developed world.

@quixoticgeek in theory it’s good news, but will they be built properly? Some supposedly A rated homes, have cold rooms, draughts etc in the winter as they weren’t finished correctly (but someone still certified them as air tight!)
