This Incredible Tool (preventing insolation) That Our Ancestors Used To Keep Cool In The Summer.
Yeah, they cost money. So does installing air-conditioning. But they use no energy ( that’d would be bad for fossil energy-producers).

The video mentions exterior roller blinds as well, wasn’t too in-depth but his main down points for them would be they still radiate heat close to the glass and they block all sunlight as well as airflow.
As a southern European, roller blinds or shutters are necessary for survival. What most people used to AC don’t realize, is that ANY light brings in heat. Roller blinds have holes in them that get closed only when you roll them down completely: if your house is somewhat cool, leaving them down with the holes open gives enough airflow while keeping most of the heat out. If you have AC, it’s even better, you don’t need much light to see inside.
