If you cool your building with air conditioning, you don't understand architecture.
Most people think AC is the solution to hot cities.
It's not.
It's the reason they keep getting hotter.
Here's the loop we're stuck in:
An air conditioner doesn't remove heat.
It moves it.
It pulls heat out of one room and dumps it into the street.
Multiply that by every building in a city, and the streets get hotter.
The hotter the streets get, the more we run the AC.
The more we run it, the hotter the streets get.
We've been spinning in this loop for decades.
But there's a way to cool a building that doesn't heat the city.
A green wall.
The plants release water through their leaves, and that evaporation cools the air around them — the same way sweat cools your skin.
The leaves shade the wall, so it never soaks up the heat in the first place.
A living wall can drop the surface temperature by up to 30°C.
No heat dumped into the street.
Just a building that cools itself and the city around it.
A hot city isn't fate.
It's a design problem.
And design choices can be made differently.
If you cool your building with air conditioning, you don't understand architecture.
