Agreed, not sure what jb1991 refers to as colder climates. Countries with colder climates normally have decent indoor temperatures during winter. In Norway for example, you would be considered crazy to have anything less than 21-22C indoors.

Where's your source? I bet there's people who keep it at 22 others at 25 and yet others at 16 in Norway.

Not Norway, but if you’re renting in Sweden, your landlord is required to provide an indoor temperature of 20 C.
