I recall some of the US contributors here mentioning a way to help
keep the house cool by actively ventilating the roof space.
With my room temp here upstairs at the sunny front of the house
currently @ 26.3C and outside air temp @ 25.4C (touched 30 yesterday)
I'd like to do something along these lines to minimise using (with the
associated electricity use) the a/c I have now.
Can you point me in the direction of the stuff that's sold over your
way to do this please ? I can't find anything in the UK but it would
help if I knew what I was looking for !

There are electric ventilation fans with a built-in thermostat that
turns them on above a certain temperature. Don't know the brands
offhand.

Lots of houses here use wind-driven turbine ventilators. They seem to
survive the harsh weather quite well:

They are called "whirlybirds" in Australia and almost every Aussie
home has a couple.
Contrary to popular belief they are not "wind driven", they have very
smooth bearings and the rising heat is enough to turn them, no need
for any wind.
