View ArticleNew 'cool roof time machine' will accelerate cool roof deployment
Cool roofs can help keep buildings cool, thus lowering the building's energy use, while also mitigating the urban heat island effect by reflecting sunlight away from buildings and cities. But as cool...
View ArticleScience looks to poplar trees for 'cool roof' technology
(PhysOrg.com) -- For as long as humans have been able to reason, they have mimicked nature in attempts to derive benefits for themselves; and just because weve become ultra-high tech in many ways, it...
View ArticleSolar panels keep buildings cool
Those solar panels on top of your roof aren't just providing clean power; they are cooling your house, or your workplace, too, according to a team of researchers led by Jan Kleissl, a professor of...
View ArticleCCNY's solar roof pod showcases innovative technology
A unique structure in the urban landscape has arisen on a plaza of The City College of New York campus over the past few months. Designed and built by CCNY students, faculty and team sponsors, it is...
View Article'Cool pavement' technologies studied to address hot urban surfaces
(Phys.org)—On those sweltering summer days—when it's too hot to play at the playground, when it seems like you could fry an egg on the pavement, when your car feels like an oven after a couple hours...
View ArticlePlant cladding keeps the temperature cool indoors despite the heat outside
Aitor Erkoreka, a UPV/EHU lecturer and researcher, has shown that green roofs are ideal for places where it is very hot in summer. So, by means of these claddings less air conditioning is needed than...
View ArticleA super cool roof solution to being hot in the city
Sydney materials scientists are claiming a breakthrough in cool roof technology with a surface they've developed that will stay cooler than the ambient air temperature, even under the mid-summer...
View ArticleCool roofs in China offer enhanced benefits during heat waves
It is well established that white roofs can help mitigate the urban heat island effect, reflecting the sun's energy back into space and reducing a city's temperature under normal weather conditions. In...
View ArticleResearcher shows cool roofs cut energy consumption year-round
As the summer heats up, so do cities. That's true not just for hot places like Los Angeles and Phoenix, but also for cooler capitals like Ottawa and Reykjavik.
View ArticleCooling down Chicago
More than 50 percent of today's population lives in cities. According to the United Nations Development Programme, that number is predicted to rise to 70 percent by 2050. Growing urbanization increases...
View ArticleHarvard reaches goal of cutting gas emissions by 30 percent
Harvard University says it has achieved a 2008 goal to reduce campus greenhouse gas emissions by 30 percent.
View ArticleHow do you cool a city in a warming world?
Globally, 2016 was the warmest year on record. In Los Angeles, temperature records were shattered last summer during scorching heat waves that saw highs of 100 degrees for five days straight.
View ArticleThe 'time machine' that replicates three years of weather in three days
Climate change is wreaking havoc on the environment. While the main culprit is carbon emissions, urban heat islands—exacerbated by dark roofs and pavements—make the effect of global warming even worse...
View ArticleStudy finds that choice of cool roofing materials can potentially impact...
In a groundbreaking study released today, scientists at the South Coast Air Quality Management District and the University of Southern California have found that widespread installation of certain...
View ArticleCool roofs have water saving benefits too
The energy and climate benefits of cool roofs have been well established: By reflecting rather than absorbing the sun's energy, light-colored roofs keep buildings, cities, and even the entire planet...
