Comment on Overheated homes: why UK housing is dangerously unprepared for impact of climate crisis
9point6@lemmy.world 16 hours agoCorrect me if I’m wrong, but surely both are necessary parts of the solution given the trajectory we’re on?
No house insulation is 100% perfect, so heat transfer will still occur even with curtains closed during the day. After some number of days at say the 35-40 degrees we’re already seeing across Europe (and let’s face it, we’re probably on track for the 50 degrees we’re seeing in Japan within a decade), the temperature will equalise internally to that.
In order to counter that we need an efficient way of moving heat from inside back out again without letting any more in, which is not something many houses in the UK can do today.

Absolutely, but critically these don’t address heat. More importantly, swapping a gas boiler for a heat pump in a poorly insulated home will just result in wasted energy and cold/damp people.
While I can’t speak for the whole of warm countries, my wife’s family is Greek and we visit often, where air conditioning is surprisingly limited given the temperatures they endure. Instead you see shutters on windows, tile floors (with rugs they pull out for the winter), and tree cover that shields the home from the outside. That’s not to say that AC isn’t common, it is, and rolling out solar everywhere is a great way to deal with that. My only objection is to the common refrain of “more heat pumps” without acknowledging that most homes in this country are so poorly insulated that any temperature regulation is lost unless it’s constant.
