Granted, I live 'up north' but it still gets hot in my new house. I mounted some exhaust fans in the ceiling to pull the hot air from where it naturally rises too. Combined with the forced air furnace fan to circulate cool air (pulled from floor level). Finds the inside of my house 9C cooler on the hottest days of the year.

This is especially important as the brick gets heat soaked and releases its heat well into the night.
