I live across the border in SA. I don't think insulation is the whole story. If it is cold I just put more clothes on. We spend nothing on heating the house. I don't know that I would want to pay more for houses to get them better insulated in a country where housing affordability is getting beyond most people and the weather is mild most of the year.
We do spend a bit on air conditioning (we sometimes get several days in a row over 40C) but the difference between winter and summer bills is not that great. Our bills are still very high. We have just replaced our fridge and water heater and I am hoping newer, more efficient appliances will help.
