A good overview of architectural and planning deficiencies in combatting extreme heat. The report isn’t anti aircon but the wasteful inefficient technology available on the mass market. I have a spray bottle that cost me a pound and if things get really hot I might turn on a fan while I spray cold water on myself.

Inevitably, an area with the potential for emissions to rise fast will get a lot of attention. But A/C shouldn't be a long term problem, because it's purely a matter of electricity supply, unlike some highly polluting industrial processes (where carbon capture will probably be necessary). And it should be fairly straightforward to balance A/C use with high solar energy production. So I don't quite the concern with A/C.

A friend of mine points out that AC is just air source heat pump running backwards. I'm not sure how you would get one unit to do both, mind.

Indeed it is, and I can't believe it's beyond the wit of man to come up with an essentially bi-directional unit?
