Yes - anything and everything you need to know about greening your roof can be found at GreenRoofs.com!
Check out all the awesome information they have on their site, including this incredibly comprehensive article by Chris Wark, entitled, "Cooler than Cool Roofs: How Heat Doesn't Move Through a Green Roof."
"Cooler than Cool Roofs: How Heat Doesn't Move Through a Green Roof" is a 7-part series explaining the key aspects of green roof heat transfer issues and the best ways to take advantage of a green roof's energy benefits.
The third in the series in entitled, "Keeping Drought-Resistant Plants Cool":
When I first started to research the thermal properties of plants, I was immediately drawn to the ones that thrive on extremely limited water availability -- desert plants -- particularly those in the southwestern U.S. states where daytime outdoor temperatures can be dangerously hot in the shade and stupid hot out in the sun. It is in the lower deserts of this region that we find plants that have been photosynthesizing quite happily in the driest, sunniest, 120 degree heat since before the advent of sprinkler systems. In the desert, nature simply doesn't provide enough water year-round for plants to rely on evapotranspiration for cooling. So what kind of plants can thrive under these conditions and how do they cope with too much heat and not enough water?
