Isn’t it annoying when you’re trying to do your part to go green and then things catch on fire? In what some are calling a case of “green on green crime,” a low-e glass window has been accused of melting the side-view mirror of a nearby Toyota Prius in Southern California. The Prius owner noticed a concentrated beam of sunlight reflecting off her neighbor’s windows, which had been treated with a highly reflective energy efficient coating, after being told by her Toyota dealership that nothing was wrong with her car. It wouldn’t be the first time good windows turned bad: Las Vegas’ Vdara hotel made headlines when its “death ray” reflected super-hot beams of light onto its pool deck, allegedly burning some sunbathers. Following reports of melted vinyl siding, pool covers, and car parts across the country, the National Association of Home Builders has launched a study about the amount of concentrated sunlight reflected from energy efficient windows.
