It's super easy. Cool to 20C during the day and close your windows. In the morning you should be well under 22C. I can do the inverse: warm my house to 22C

It's super easy. Cool to 20C during the day and close your windows. In the morning you should be well under 22C. I can do the inverse: warm my house to 22C and turn off the furnace overnight when it's -30C. The house won't drop below 20C. And that's a 50C differential. A 14C differential is trivial in comparison.

So you have thousands of dollars worth of insulation because you live in an arctic climate. Congratulations I suppose. Now instead of just spending hundreds of billions on building a new grid Australians will also have to spend hundreds of billions on insulating their houses.

  To be completely honest, they probably should, and people don't talk enough about proper insulation regardless of the region. E.g. in colder climates many modern buildings are just hermetically sealed boxes with issues around CO2 levels etc.

  For a 14C differential you don't need insulation, you just need to seal leaks.

      If your house had problems with condensation forming on the outside then I hope it never rains where you are.

        Water in liquid form (e.g., rain) will (mostly!) go down with gravity, and so overhangs will help a lot, as will proper grade sloping away from your foundations. Water in vapour form will be more diffuse and be everywhere the air is. Further, your cladding / water control layer (which deals with rain (and UV)) generally needs to be open to air so that it can dry properly: * https://en.wikipedia.org/wiki/Rainscreen https://en.wikipedia.org/wiki/Rainscreen so that can lead to moist air getting places that water may not, and if you don't have insulation between the warm-moist outside and the cool-dry inside: * https://buildingscience.com/documents/insights/bsi-001-the-perfect-wall https://buildingscience.com/documents/insights/bsi-001-the-p... problems can start.
