I love the sentiment, but there’s no data included. I have trouble concentrating above 75F inside a room, how much lower than ambient are these structures cooling? 88 would be way cooler than 105, but it’s still fucking hot- maybe it’s dry heat.
People have been building passively-cooled buildings for centuries. Cant see any data for how much they cool buildings by, but this article mentions buildings in Dubai reducing their energy use 23% to keep an equivalent building cooled when designed to use passive cooling: https://www.sciencedirect.com/science/article/pii/S209526351400003X
I’m not saying passive cooling doesn’t work, I’m aware of convection cooling systems, I’m just saying the article talks all about highs and doesn’t give any other data- is it capable of cooling the air below ambient? Is it simply allowing air to not creep above ambient? Does it generate measurable breeze?
I suspect it’s a combination of bricks being a heat sink and vents allowing convection currents, but I know what 100+ feels like in my garage with all the doors open and it’s still brutal.
That’s what I was thinking too. They mention cooling but attribute it to the roof and doesn’t mention anything else. That metal roof alone won’t be enough to keep the place cool.

Thanks!

And metal roofs radiate in both directions
