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.
Also how well do these cooling methods work with humid air.
According to this, the way to go in humid environments may be to make "green" roofs. I am not a scientist or scholar so I don't know if that piece is credible or not and I only did a cursory scan of it. Maybe someone that knows more is willing to enlighten us.
