Dunno - you'll have to work it out for yourself!
Can't say I've ever suffered from unwanted heat gain in Britain. I'd
open the windows and generate a bit of through draught.
The french have the answer to summer heat - high ceilings, large
windows opening inwards with slatted shutters closed on the outside -
bliss, who needs air conditioning?

So why don't you live in france ?
