Another cooling type of architecture is a form of wind channel. Maybe what Mark calls a solar chimney, but part of the centre of the construction, not a metal add-on.
I wonder whether either of them can also be used as water collector by adding a fine wire mesh where moisture can condensate and drops into a basin for household use.
Such wire mesh water collectors have test installations on Portugals islands and somewhere in Tunesia or Morocco, places where fog or at least moisture in the air is a typical landscape feature.
It's very low-tech if the installation stands higher than where the water will be piped to.
Cooking and sweating also creates fog 
precious water.
But let's also remember: we in the rich countries don't have a budget left at all for built infrastructure. For fighting poverty, only poorer countries can still add built infrastructure.
By rights, we actually need to dismantle our office towers (full of workers in bullshit jobs, according to David Graeber) , univs, roads and hospitals, and send the material to G-South in order to give their populations a chance to come level with our wealth.
