What type of bricks? I have lived in brick - and brick veneer/faced 
homes. And in a home built of glazed terra-cotta tiles with openings 
similar to standard cinder block in them.

The terra-cotta built home was much cooler than the brick or brick faced 
homes overall. Probably due to the internal openworks allowing the 
thermal loading to escape upwards in the thermal convection circulating 
the air in the walls.

The solid bricks, however, did soak up the solar thermal load and 
transmit that load into the interior of the home long after the sun had 
dropped below the western horizon. If your homes in Adelaide are built 
from clay bricks - whether fired or adobe style - I think you are full 
of prunes on the main heat input coming through the windows and roof. 

I'll give you roof - as it will be nearly the same whether a tin roof or 
a more (USA) conventional asphalt shingled roof. A tiled roof would have 
much the same effect as a brick sidewall - becoming a heat sink for 
solar energy.

However, the solar energy loading from the windows can be defeated by 
white/light coloured draperies or blinds which reflect the heat rather 
than absorb it to be released into the interior at a later time.

Back in my hippie/counter culture/Mother Earth/alternative energy days - 
at least in the more active/intense period - I made quite the study of 
alternative heating methods ... which, quite naturally, led me to study 
the thermal effects of various construction materials. And before anyone 
makes any smart@$$ comments, I am still "in my hippie/counter 
culture/Mother Earth/alternative energy days". Just a bit more sedentary 
than when I was younger.

If I were building an energy efficient home damned near anywhere below 
the Arctic Circle I would build an earth-sheltered (cave) home. It has 
long been said that we live in upholstered caves. I see the problem with 
that being that we have removed the units from their sheltered (cave) 
environment and made them stand out in the weather on their own.
