Our current home we focused on the solar aspect. The back of our home is north, the windows are protected by eaves and the large alfresco. The west side is the bathroom, toilet, scullery, laundry & Miss S's room. We have tinted Miss S's room windows and used 2 long narrow windows. With the south being the front of our house the 2 bedrooms stay cool as well as the garage.
