I think they mean designing homes to be more efficient in the heat to stay cool.
And yes, it can help on 35c / 95f days.
In Australia, even in a non aircon place I'm pretty much fine at 35c. Provided: I have a small fan, and I keep the place air tight. Having proper insulation would help a lot.
It's kind of a little known trick, on really hot days (95+) you want to open the windows but you really need to keep them closed to keep the cool air in and hot air out.

So, passive solar water heaters can use black painted copper piping to heat water directly with sunlight, no electricity required. Wind is caused by solar energy and can have a cooling effect without first being converted to electricity. Etc. When done right, it is vastly more efficient and has far fewer side effects in terms of things like waste heat.
