I get that a lot of houses in Europe don't have built-in air conditioning.

What I don't get is the argument that houses built to hold in heat in winter are inherently hard to cool. Insulation works both ways? In Texas, we want as much insulation as possible!

I get it's an infrastructure problem but it's one that has been staring Europe in the face for decades.

@gwynnion I wonder how easy it is to swap out air at night. I'm in a super eco house, but we're kinda set up with this in mind.

But I think it's just that Europeans aren't thinking that way yet.

@humanadverb It's purely a question of how hard you want to run the unit. I've always been told the optimal temperature is 30F under the outside temperature. Otherwise the system will be strained. The more insulation, the better in that case.

Europe is the fastest warming continent on Earth but there seems to be a gap between the way they think and the reality of the situation -- and a lot of negligence on the part of their governments who've done nothing to mitigate it.
