Cool Roofs Lithia Springs GA

Solar panels are a great way to save energy and help the environment.

The Cool Roof Rating Council tells us that a cool roof reflects and emits the sun's heat back to the sky instead of transferring it to the building below. "Coolness" is measured by two properties: solar reflectance and thermal emittance. Both properties are measured from 0 to 1 and the higher the value, the "cooler" the roof.

Benefits of cool roofs include:

• Energy savings
• Global warming mitigation
• Reduction in urban heat island effect and smog
• Improved occupant comfort
• Compliance with codes and green building programs

The topic of cool roofs was featured recently in an article by Todd Woody , who says, "Green Wombat often highlights high tech when it comes to tackling global warming and energy independence. But a new study from the University of California's Lawrence Berkeley National Laboratory shows that simply installing white roofs on homes and commercial buildings - to reflect the sun's rays rather than absorb them - can reduce air-conditioning costs by 20% and could save $1 billion a year in energy outlays in the United States."

In the study, the scientists calculated that a global white roofs and roads effort would offset 44 billion metric tons of greenhouse gas emissions, or more than a year's worth of carbon, and help stabilize future C02 emission increases. Another intriguing highlight of the article is the note that "Installing cool roofs and cool pavements in ci...
