Window Heights

Doing lots of reading tonight on eaves and windows.

Feel on top of the eaves depth and that 30% of the height to the underside of the eaves if permanently shaded and so is better not glazed.

So am I right in thinking with eaves in Adelaide a north facing sliding door should be 1680mm high
( ie wall 2400 high - minus 30% is 1680)???

So we are thinking to go 2100 high (the lowest we would go with no banging heads) on a 2400 high wall.

But the confusion is normal room windows is there an appropriate distance off the floor for the lower sill and is there a tipping point for the effectiveness of the glazing. We don't want sliding doors in bedrooms.

Clear as mud?????? What is the ideal dimensions ie height of a north facing window in a 2400 high wall with 900 eaves or 600 eaves - ie sill height and total height.

Some thoughts about North facing windows cill height.

No need for glass below the point that the window is shaded by a fence or neighbour (see http://www.anewhouse.com.au/2012/01/winter-sun/ to check)

Do you want any furniture on that side of room? In that case cill height to be at height of furniture.

I actually don't mind patio doors in the bed room as it meant that I could still see the garden when I was in bed.

Copy this to scale then slide out your eaves or raise/ lower your window sill/head to suit.
