White Roofs Could Reduce Urban Heating

To help combat global warming and urban heating, we might just need to paint the town white.

A new modeling study simulated the effects of painting roofs white to reflect incoming solar rays and found that it could help cool cities and reduce the effects of global warming.

The feasibility of such an initiative for cities remains to be seen, researchers caution, but the idea has been backed by U.S. Energy Secretary Steven Chu and other policymakers. And now there's some science behind the political support.

"Our research demonstrates that white roofs, at least in theory, can be an effective method for reducing urban heat," said Keith Oleson, the lead author of the study and a researcher at the National Center for Atmospheric Research (NCAR) in Boulder, Colo. "It remains to be seen if it's actually feasible for cities to paint their roofs white, but the idea certainly warrants further investigation."

Cities are particularly vulnerable to climate change because of a phenomenon known as the urban heat island effect. The asphalt roads, tar roofs and other artificial surfaces that permeate cities absorb heat from the sun, making temperatures in urban areas on average 2 to 5 degrees Fahrenheit (1 to 3 degrees Celsius) higher than in rural areas.

"It's critical to understand how climate change will affect vulnerable urban areas, which are home to most of the world's population," said NCAR scientist Gordon Bonan, a co-author of the study, which will be detailed in an upcoming issue of the journal Geophysical Research Letters.

Reflecting light

White roofs could reflect some of that heat back to space and cool temperatures, because white surfaces reflect most of the light that hits them, while black surfaces absorb most of that light. (The amount of light that a surface reflects is known as its albedo.)

Oleson and his team used a newly developed computer model to simulate the amount of solar radiation absorbed or reflected by urban surfaces. The model simulations, which are idealized representations of cities, suggest that, if every roof were entirely painted white, the urban heat island effect could be reduced by about a third.

Such a reduction would cool the world's cities by an average of about 0.7 degrees F (0.4 degrees C), with the cooling influence more noticeable during the day, especially in the summer.

Real world

White roofs could also cool temperatures inside buildings, which could change the amount of energy used for space heating and air conditioning. This in turn could affect the consumption of fossil fuels, which generate many of the greenhouse gases responsible for Earth's warming. Depending on whether air conditioning or heating is affected more (as you might have to turn up the thermostat due to cooling temperatures), this effect could either magnify or partially offset the impact of the roofs.

"It's not as simple as just painting roofs white and cooling off a city," Oleson said.

The location of the city, the density of roofs and the construction of a building could also affect how much cooling would occur with white roofs.

The researchers also note that their results are a hypothetical look at cities and that the actual cooling effect in the real world could be slightly less, because dust and weathering would cause white paint to darken over time and parts of roofs would remain unpainted due to openings such as heating and cooling vents

2010-A Foam Odyssey

Where is your business going this year? Is success achievable in this economy? Has the competition reduced the pricing in your market to the point where you fear your own business mortality?

There are cheap prices and cheap products, don't buy OR sell based entirely on a cheap price folks. There are products out there that will provide you with the ability to compete in a manner that your competition is oblivious too. Reward your customer with knowledge of your product, quality of your service, and superiority of the chosen brand and you'll reap a continued reward of success in the year 2010.

The Junction Crew provides the service of closing the sale by offering the applicator flexibility from concept to completion. Every job is different thus not every foam performs equal to the task needed.

Give us a try today-it'll cost you NOTHING to make the call & I guarantee I'll open your eyes. Happy New Year & Good luck!

Used spray foam equipment

There are plenty of equipment hunters out there and if you are one of them-be aware. Technical support, training, certification, and continued support is utterly critical for entry into the spray foam industry. Quite frankly, I/we don't want people entering the industry without it. There is entirely too much at stake to gamble on someone being technically savy enough to survive.

On the other hand, if you are trying to sell used equipment, I get calls on a daily basis looking for quality used equipment and I'd be willing to facilitate the sale of your equipment insuring that the buyer receive the support, training, certification, and follow up support needed to have a chance at success and be the good steward that we all want.

I HAVE CUSTOMERS RIGHT NOW WANTING THE FOLLOWING:
1) E20 Shore powered unit-QUALITY ONLY, NO JUNK
2) E30 Shore powered/generator powered unit-ditto above
3) E20 Generator powered unit-

Price based on location, quality of equipment, and inspection by an authorized Graco technician. Again, here to help if the need arises.

A Happy and......

Safe Thanksgiving to you all.
