Brick is good at slowing heat down. Used well, a brick house stays cool on a hot afternoon and warm on a cold night.
Thermal mass
Thick masonry walls absorb heat during the day and release it at night. Inside, that evens out the temperature.
But shade first
Mass only helps if the sun is kept off the walls and windows in summer. Deep roof overhangs and covered verandas do most of the work.
Let the night air in
Windows on opposite sides of a room let cool evening air flush out the heat stored during the day.
