Design Thinking: White Roofs Are Cool

White roofs are set to rise in popularity in the coming years, and the reasons aren’t purely cosmetic. Current white roofers MINI, Toyota FJ Cruiser, and Ford Flex (above) have carved out a unique design for themselves based on this treatment, but the reality is that there are energy-saving benefits, too. Think of desert wardrobes or Greek buildings: white reflects the sun’s rays better than any other color.

Design thinker Diego Rodriguez, from design firm IDEO and Stanford’s d.school, recently wrote lovingly about the benefits of white roofs on his Metacool blog, one of our favorite bookmarked sites. His thinking: white roofs improved the design of some early vehicles, no doubt hiding a few flaws, but their real benefit is heating and cooling. Less power is required to keep a car cool if it has a white roof.

Rodriguez’s suggestion is that the image-savvy engineers at Toyota should take this to heart and make all Prius roofs standard in white.

Better yet, paint the roof of every Prius white. The better to bounce sun rays back and reduce the air conditioning load. Plus, white roofs are in. Critically, tell owners why the roof on their car is white (even if they paid $2,000 extra for black paint), so that they can educate their friends about the concept of albedo.

Whether or not you care about albedo doesn’t matter. We like Rodriguez’s insight because the white roof story isn’t something that’s being sold in the marketplace, despite its benefits. Will Toyota and others adopt more white roofs in the future? Or create an even-more-reflective surface that helps in cooling? One can’t imagine why they wouldn’t.

I think white roofs look nice on white cars.

If I remember correctly white roofs are not new. Citroens had them in the 50’s & 60’s. when driven in Africa.

Certain Land Rovers have sported the look in the past as well. Cosmetically, it appears more appropriate on an SUV, reminiscent of white canopies covering safari-bound trucks; however, if it catches on as a cost-effective “green” solution, I’m sure we’ll continue to see a rise in white-roof popularity in the car segment.

Eh, white roofs are nice to look at I suppose. But as far as the “green” benefits go I’d rather see us throw more money at development of cost-effective photovoltaic cells so that they can be incorporated into a car’s roof structure.

Funny, Minis first sported contrasting roof colors when racing. John Cooper painted the roofs of his team cars to better differentiate them from others in the race. Not just white was used, also employed were silver and black. Nice to see that a simple nod to the past can have a positive impact in the efficiency of a car today.

I nearly purchased a white car in 2003 (as a poor grad student) after having spent two summers driving a maroon 92 camry with broken a/c and both driver’s side windows not working. I remember walking around the car lot placing my hand on the top of each car to see how much solar radiation each color paint was converting into heat. White paint is appreciably cooler. A white roof is the perfect compromise for cooling, plus I think it looks nifty…

On a related note, black window tinting slays me… it’s like the anti-white roof. Solar energy comes in through the glass, gets converted to heat on the film and heats the interior of the car. I wonder if there’s anyone driving around out there with a prius with dark black window tinting wondering where all there gas mileage is… heh…

[…] Once upon a time and not so long ago, it seemed that every other car in Japan was painted white. For a whole number of reasons, the Japanese like white, big time. Perhaps it has something to do with the inherent goodness of its properties. […]

[…] During our time at the New York Auto Show, the folks at Ford took us for a spin in 2009 Flex. While we weren’t given the opportunity to get behind the wheel, we probably wouldn’t have gleaned a whole lot of valuable driving experience in the miasma that is the Big Apple’s bumper-to-bumper shuffle, but we did take the opportunity to get learn more about the vehicle’s interior and many features.
