Once upon the time... *All* windows opened. Even those which had no
glass in them just the shutters... Those were the good times for humans
(and bad times for mould, I suspect)

I've only encountered air conditioning in modern shops and ofices.
Everywhere else relies on opening doors and windows and portable fans.
Portable air conditioning units are available in the big DIY stores, but
they're not something we seem to have latched on to.
During the recent very hot and humid weather, we opened all windows, but
kept doors locked as usual (Tamara's other email on paranoia). We also
closed curtains/blinds on the windows when the sun was shining directly into
the room, opened those and closed the ones in the next room as the sun moved
round. Unfortunately as there was no breeze, the open windows didn't create
a cross draught, but we were less hot than we would have been with them
closed.
Don't know what the current building regulations are, but it used to be that
there had to be a minimum amount of opening area per certain area of glass.
This was partly for ventilation and partly as a means of escape in case of
fire, especially now that most people have double glazed windows which are
very difficult to break because of the vacuum between the two panes. They
need to be hit with something pointed and hard near a corner - hitting in
the middle will just bounce.
Because we have a gas fire in our living room, we have a permanently open
vent in one of our windows. It's checked annually when the fire is serviced
and is a regulation to guard against carbon monoxide poisoning.
