Green on Green Crime: Energy Efficient Windows Melt Toyota Prius

National Association of Home Builders has promised an investigation into heat-glare from window treatments
Heather Patron of Studio City (Los Angeles, Calif.)
her neighbors of a dastardly crime -- melting her Toyota Motor Comp. (
. No, really. This was no Hawaiian Baby Woodrose-induced optical illusion, her neighbors’ energy-efficient window treatment had melted the plastic molding of her Prius' mirror housings.
Los Angeles is a seasonable southern city on the west coast. Its average monthly maximum temperatures are historically confined to the 64-77 ºF range year round [
]. Unsurprisingly, the big concern for residents in terms of energy efficiency is the cost of air conditioning. One of the major sources of heat entering the house is through window light. So southern Californians, like residents of other longitudinally southern U.S. states, have taken to applying reflective windows treatments, both as a cost-saving measure and as a "green" energy saver.
But in this case the approach backfired, as the neighbors' energy efficient reflective gloss created a brilliant beam during daytime hours that directed itself directly at the car port.
"The side view mirrors were melting. Anything that was plastic on the car was melting," the Prius-owner recalls.

And Ms. Patron says her Prius wasn't the only ones damaged -- a neighboring vehicle saw similar melting. She comments, "I'm positive that this window is what is causing the damage to my car. I just don't feel like it’s fair. I feel like it needs to be known that this is happening. And a lot of people probably have damage out there, that they aren't aware that it’s the windows that are causing this."
She claims to have measured the temperature in the car port when it's exposed to the beam and found it to be 120 ºF.
The damage occurred in Studio City, a suburb of southern California's biggest city, Los Angeles. [Image Source: Google Maps]
Similar claims of reflective windows burning people or plastics were
leveled in Sept. 2010 by a lawyer staying at the Vdara hotel
in Las Vegas, Nevada. Reportedly in that case the situation was even more severe as the reflective windows were acting as a hyperbolic solar dish, focusing sunlight into a "death ray", which swept across the pool deck.
Reportedly other homeowners have also complained about plastic-melting reflective beams coming off windows with certain energy-efficient treatments. The
National Association of Home Builders
has promised a thorough investigation into this problem.
What makes Ms. Patron's story more curious is that automotive mirror housings are usually primarily composed of ABS (acrylonitrile butadiene styrene) [
] -- the same type of plastic found in LEGO blocks and plastic pipes. Pure ABS has a melting point of 221 ºF [
], so it's unclear how the beam was able to melt the plastic, even if the air temperature was 120 ºF.
One possibility was that the black mirror plastic absorbed the light, and heated up to a temperature far hotter than the surrounding air (think of an Easy-Bake oven).

The Prius is the best-selling hybrid electric vehicle in the world. As of March 2011,
3 million Prius vehicles had been sold
worldwide, with 1 million sold in the U.S. alone by April 2011.

Mick, since when is 64-77 rather hot? Thats rather comfortable to me.

Wikipedia fail by the article's author. Who uses year average temperatures (correct as stated) highs in January are 59 to 73 while in August highs are from 79 to 90? Articles with facts so irrelevant as to border on wrong would be nice ;)

Temps climb rapidly once you leave the metro LA area which is right on the coast. I have seen temps inland there climb to 100+ on Summer days.
Granted, I really don't know if this is the case for where she is located, but in some areas it could easily be 110+ in the garage with the reflections shining on something black and hollow like the mirror. Imagine what the temp has to be inside the mirror assembly to do that.

My town's yearly average temperature is 40. Yay me......
