Things to aid cooling / avoid heat gain

[Daox]

We have a pretty good list of things in our 60+ home energy saving tips. Is there anything else you guys can think of that we can add to the list?

Cooling

Turn the A/C thermostat temperature up as high as is comfortable, sometimes using the A/C just to dehumidify the house may be enough to be comfortable.

Use blinds (good) or awnings (better) to block direct sunlight.

Use reflective window film to block direct sunlight but still let light in the house.

If possible, open the house up at night and use box fans in windows or a whole house fan to cool the house down instead of relying on the A/C.

Install radiant barrier insulation in your attic.

Place window A/C units on the north side of the house or any place where the sun does not shine on them.

Use fans to allow you to increase the A/C temperature and still stay comfortable.

Use solar screens to block more sun from entering through the window. This still provides light but reduces direct sun light and the heat it brings.
