Did you ever find a solution for your whole house fan on a flat roof?
I
am looking for that now for N. AZ house we're building.

Usually called a swamp cooler in the USA. They have separate
controls for the water spray over the pads and for the fan so
can be used with just the fan for what you want to do.

A swamp cooler isn't a whole house fan, ****wit.

Yes it is when it dumps the air into the whole of the house, ****wit.
