Via the Christian Science Monitor, a article on how – as cities confront global warming by reflecting sunlight or planting gardens – they could add to winter heating costs or even decrease rainfall in some regions: “Cool” roofs and roofs covered with vegetation can be effective tools for keeping people who live in America‘s broad, […]
Read more »Via Renew Economy, an interesting report on the potential of white roofs: Painting building roofs white could cool some major cities baking in the intensifying heat of a changing climate. How much benefits white roofs could bring depend on the region of the country they’re installed in and the season, new research shows. Keeping cities cool in […]
Read more »Via Architizer, an article on white versus green roofs: Over the last decade, green roofs—that is, rooftops planted with living vegetation—have been touted for their environmentally friendly benefits. But while they certainly help prevent rainwater runoff and provide extra insulation, a new study shows that the sustainable rooftop garden might not be the best solution […]
Read more »Via Energy Daily, a comparison of the economic benefits of different colored roofs: Looking strictly at the economic costs and benefits of three different roof types-black, white and “green” (or vegetated)-Lawrence Berkeley National Laboratory (Berkeley Lab) researchers have found in a new study that white roofs are the most cost-effective over a 50-year time span. […]
Read more »Via Ensia, an interesting look at the cool roofs movement and how reflective roof coatings and materials bring multiple benefits: Millions of dollars and massive amounts of fossil fuels are spent cooling homes and buildings covered by conventional roofs that absorb sunlight, get as hot as 185 degrees and radiate that heat inside. Add to […]

By 2016, new installations are expected to occur every 90 seconds. Two thirds of the solar capacity in the U.S. has been installed in the past 2.5 years and in the next 2.5 […]
