Comments Off on New Study Shows White Roofs are Three Times More Efficient than Green Roofs

Although having a garden on the roof of your house might look great, a lot of evidence suggests that roofs painted white are much better for the environment. A recent study published in the Energy and Building Journal compared three types of roofs-green, black and white-and came to the conclusion not only that white roofs have great economic benefits, but are also three times more effective than the other two at fighting climate change.

La Petite Ceinture traveling market takes abandoned Parisian train lines and converts them into low-impact infrastructures for easily transportable markets. The project envisions a less polluting alternative to traditional markets and one that rehabilitates decommissioned or underused urban networks. It was designed by by Amílcar Ferreira and Marcelo Fernandes as an entry for the 2013 M.ART Opengap Competition , which focuses on redefining the concept of the “market” as a commercial space.

White roofs in winter in Winnepeg After posting about the benefits of white roofs, (as Mike did here on TreeHugger ), Andrew Sullivan published a couple of letters from readers questioning their benefits. I had a look at this issue two years ago, and wrote that Arguments Against White Roofs in Northern Cit… Read the full story on TreeHugger

White Roofs Could Save a Year’s Worth of Global CO2 Emissions

Comments Off on White Roofs Could Save a Year’s Worth of Global CO2 Emissions

An infographic created by the White Roof Project , an initiative that wants to help cover the world’s black roofs with white paint , illustrates some impressive statistics about the power of white roofs , including the fact that the transition from black to white roofs could prevent the emission of 24 billion metric tons of CO2, the same amount of CO2 emitted globally in 2010. The project says that if we covered just 5 percent of roofs with white paint per year, we’d be done by 2030. White roofs can reflect 85 percent of sunlight compare to 20 percent for black roofs and buildings with white roofs stay up to 35 degrees cooler, which means less electricity required for cooling the buildings.  In large cities, white roofs also curb the heat island effect, cooling the city as a whole. In addition to the emissions savings, white roofs could save 14 power plants’ worth of energy in 11 large cities, save $5 billion in energy costs in the U.S., reduce smog, blackout risk and heart-related deaths and Bill Clinton has said it’s the quickest, cheapest thing we can do.  So, what are we waiting for? If you live in NYC, you can volunteer for the White Roof Project or adopt a building.  The project plans to cover the roofs of an entire East Village block in white paint this August.  You can view the entire infographic here . via GOOD
