White Fright Off-white roofs are cool! (Code Green)
Want a Reflective Roof? Pick any color! The host for this episode is Howard Wiig. The guest for this episode is Ronnen Levinson, Ph.D.
Dr. Levinson, the author of many papers on reflective surfaces, describes the performance benefits of roof and wall colors that reflect the sun’s heat more cost-effectively than insulation. Levinson is one of the world’s leading experts on reflectivity and will enumerate the considerable potential of cities that reflect the sun’s heat to make a considerable contribution to cooling the planet. He demonstrates that roof and walls need not be white—that there are hidden substrates in paints that allow medium-colored surfaces to reflect much of the heat striking the surface.
