White roofs beat 'green' roofs on climate change, says Berkeley Lab study http://apocadocs.com/s.pl?1390437869
Though so-called "green" roofs with gardens growing on them are popular today and have some environmental advantages, plain white roofs reflect sunlight and reduce global warming.
According to a study from Lawrence Berkeley National Laboratory, a simple white roof reflects three times as much sunshine as a green rooftop garden. "By absorbing less sunlight than either green or black roofs, white roofs offset a portion of the warming effect from greenhouse gas emissions," the lab said.
