Hello,
We are finishing off a build on the Fleurieu peninsula in SA, the usual story, had to move in before it's quite finished.
Now I know we are having a heatwave and all but the house is really not performing as I'd like, it's getting really hot,so that even when the house cools down the furniture is hot!!!
There are a couple of things that I know are making it hot, and this is because the build isn't complete, there's no shading on the north facing front and there is a lot of glass there so I know this is acting like a radiator plus there is no western shading on those two windows yet ( i know everyone is now shaking their heads sadly at our folly ).
I know that these fixed shades should be there but there's a long story behind this all....
The thing is that although the back part of the house is cooler, ( house is about 7m deep) and the air circulation is good, even in the back of the house all the internal wall linings are hot at the middle of a hot day. There's a section where the internal lining is off and I've checked the external wall construction/ insulation and I want to know if the architect has f***** up almightily as the wall is this, colourbond outside, then foam/foil insulation with foil facing inwards, then batts in the wall cavity .
So my questions are:
Would the lack of shading make the house that hot so that internal linings (walls) heat up to that extent?
How deep should our north and west fixed shading be, the plan says 900mmm? Is is different for west shading ? Windows are double glazed
And has the architect stuffed up with wall insualtion with the result that the back walls,in the cooler part of the house are heating up or is that the sole result of the radiant heat via the unshaded windows ???
Any advice appreciated
