David Ho @davidho.bsky.social · 28d Instead of air conditioning, this is how Parisian schools are adapting to extreme heat. This is the same thing people in the UK were doing 50 years ago during the 1976 heatwave.

It was 104 in Paris when I was there in 2015. We opened the windows at night to generate a breeze. No air conditioning.
You only cut off air circulation and it will still heat up…. Because there are people inside. You will need some form of ventilation and cooling eventually. Doesn‘t have to be an AC though.
This is effective. It's called albedo replacement therapy.
Common in Japan to see people put them on their parked cars.
I use car reflectors, interlocked on curtain rods hung on cup hooks. Across the verandahs. Cut's 10 degrees off the heat/cold. Really helps when it's 45C with overnight lows of 39C
I don't have anything shiny but papering the sunny kitchen windows also helps (low key solution)
It's better than nothing but it does not solve the issue linked to the heating of the walls themselves: they become almost as hot as the outside at the end of the day and start to heat the flats. Since temperatures decrease slowly at night, the inside continues to become warmer by the days. :(
