Roofs

The new roof, re-named 'Foro Ciel,' is now home to some species of cacti and a few small o...

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

The Velux Solar Powered Fresh Air Skylight

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

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.

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.  Read More

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.  Read More

The 'Thermeleon' roof tile changes from white to black depending on its temperature

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).  Read More

'Green roofs' like these rooftop gardens atop the Rockefeller Center may go a long way to ...

‘Green roofs’- urban rooftops covered with plants - are gaining in popularity to help buildings reduce their reliance on air conditioning, and now scientists in Michigan are reporting they could also help fight global warming by eliminating carbon dioxide in cities, more effectively than was first thought.  Read More
