I'm in Australia, where we have 39C and 40C and 41C and 42C days in summer,

and I have multiple complex health issues that mean that, even with aircon chewing through electricity,

I get so debilated by the heat that I can barely get out of bed to get a drink of water or go to the toilet.

I'm 100% in favour of more street trees, more garden trees, more insulation, and better house design to limit how much aircon most people need,

but even with the best design in the world, some of us are still going to need truly ridiculous amounts of airconditioning because our bodies can't thermo-regulate :(
