At this stage I am not going to weigh in as an expert. In my previous blog I commented on my children’s science experiments that clearly demonstrated that the brick colour can have a huge impact on the heat absorbed by the bricks.
I grew up in Wagga Wagga in a brick veneer house. In summer it got hot. And in the evening it got worse. While the outside temperature slowly dropped, the brick just radiated heat.
The bricks were dark red. Of course it would be a furnace.
But what about the modern “green building”. I recently spoke to an expert Scinergy (http://www.scinergy.com.au/) who had some fantastic recommendations on what is required in the modern home. One of the points they made is that the aim is to have proper insulation in place.
But what about all the places where insulation isn’t in place? So the covered decking out the back? Or the shed.
And if you do have an existing old house, what then? In my old Wagga home a couple well placed deciduous trees would probably be awesome (shade in summer, and heat absorption in winter).
I also saw results from heat reflecting paint that cut the temperature under the factory roof from over 80°C to 45° and the corresponding drop in air-conditioning power consumption was huge.
So I would like to ask people, should we be giving really strong consideration to the colour of our building materials?
