The next time you paint your home please consider the use of energy efficient paints. These new space age materials are cost-effective and will present a reduced thermal footprint that keeps radiant heat from the sun out of your dwelling. These paints also function in the same manner when applied to the inside walls of a house; your home will remain cooler during summer and warmer during winter.
I invite you to learn more about these paints, and to see how the University of Colorado used them as part of their winning Solar Decathlon entry. For more information: energy efficient heat shielding paints
