Home Cooling

Although your first thought for cooling may be air conditioning, there are many alternatives that provide cooling with less energy use. You might also consider fans, evaporative coolers, or heat pumps as your primary means of cooling. In addition, a combination of proper insulation, energy-efficient windows and doors, daylighting, shading, and ventilation will usually keep homes cool with a low amount of energy use in all but the hottest climates. Although ventilation is not an effective cooling strategy in hot, humid climates, the other approaches can significantly reduce the need to use air conditioning.
