Yeah by 7 star I mean the real shit that makes a difference like sealing the envelope, window size and orientation, insulation, double glazing. I totally agree it's not the right system in current form to achieve energy efficiency because of the stupid shit like outdoor clotheslines and water tanks, and the fact you can still have a glazed western wall.Saving the planet with big brain thinking.
That all depends where you live. Queensland, shade and ventilation give you the most bang for buck, Canberra sealing the envelope does. Insulation is second, double glazing is third on the priority list for Canberra. Roof insulation in Qld. We are the worst on the planet as far as building climate functional homes.You'd have to go a lot higher, or simply mandate better R values as minimum standards for the insulation. The insulation change would be the most cost effective way to do it too.
Once again it costs more money up front to do it properly (kinda like electric cars) so we'll just wear the ongoing fuel costs because we want marble benchtops.
