Coated polymer stack promises to keep your roof cool in summer

By - June 1, 2015 2 Pictures

Of all the scenarios you'd want to find yourself in a heatwave, being barefoot on a hot tin roof would be toward the bottom of the list. These exposed surfaces soak up sunlight to slowly but surely transform into corrugated hotplates, compounding the sweltering ambient temperatures and warming the living space below. But a team of Sydney-based scientists has developed a new material that's claimed capable of keeping a rooftop cooler than the air that surrounds it, saving energy and sweating residents in the process.

Disused helipad transformed into Foro Ciel rooftop garden and office

By - April 26, 2013 12 Pictures
When Coca-Cola found itself with an unused helipad on top of its building in Mexico City, the simplest thing to do would have been to strip everything down, leaving a bare rooftop. But that would have been a waste of usable real estate, not to mention just plain dull. Instead, the company enlisted the help of design teams at Rojkind Arquitectos and AGENT to convert the area into a sustainable rooftop garden and customizable office space. Read More

Solar-powered skylight opens and closes by remote control

Skylights are a nice way of letting daylight into your house, and if they can be opened, they’re also effective at letting out the hot, stuffy air that rises to the ceiling. Depending on their location, however, they can be difficult to open without running electrical wiring up to them. That’s why Velux has introduced its no-wiring-required Solar Powered Fresh Air Skylight. Read More

Dow Solar rolls out Solar Shingles in California and Texas

By - April 25, 2012 5 Pictures
Installing photovoltaic panels is certainly the most common method of generating solar power on a rooftop, and in fact many people might think it’s the only method. There is, however, an alternative – photovoltaic shingles. It makes sense, when you think about it ... why install weatherproof shingles and solar panels separately, if you could get one thing that combined both? Although there aren’t many manufacturers offering such products just yet, this month Dow Solar made its POWERHOUSE Solar Shingles available to consumers in northern California and central Texas.

Computer modeling indicates white roofs may be a cool idea

By - January 28, 2010 1 Picture
Previous studies have indicated that painting the roofs of buildings white could be a low tech way to reduce global warming by reflecting the sun’s rays back into space. Now the first computer modeling study to simulate the impacts of white roofs on urban areas worldwide has added more weight to such a proposal indicating that painting every roof in a city entirely white could cool the world’s cities by an average of about 0.7 degrees Fahrenheit or 0.4 degrees Celsius.

Thermeleon roof tiles make saving energy as clear as black and white

By - November 29, 2009 3 Pictures
Prototype roof tiles that turn white to reflect heat when they get hot seem like a pretty cool idea, as do tiles that turn black to absorb heat when it’s cold. That’s why a team of Massachusetts Institute of Technology (MIT) graduates has won the third annual MIT MADMEC (Making and Designing Materials Engineering Contest) by demonstrating their thermally-activated, color-changing, roofing material called “Thermeleon” (as in chameleon).
