**Shades or blinds are the most effective means of preventing unwanted heat and sunlight from entering a house.**
This lowers cooling costs. And, by employing a combination of strategies such as this one, it's possible to eliminate air-conditioning altogether in drier climates.
Shades or blinds mounted to the outside of the building are best. Available with manual or automatic controls, their sometimes complex, weatherproof hardware can add to the cost. Manual shades require an operator for changing weather conditions, or the benefits are lost.
