'Green' roofs help reduce global warming

Hello everyone here Ji, This morning I got following mail in my mail-box from my DIL, which I wish to share and contribute, whatever we can do to our planet as a whole. Please do come with some more suggestions and experiences.

They found that green roofing an urban area of one million people would capture more than 55,000 tons of carbon. That's an amount "similar to removing more than 10,000 mid-sized SUVs or trucks off the road a year," their research stated. Green roofs reduce heating and air conditioning costs, retain and detain storm water. Green roofs also absorb carbon dioxide, a major greenhouse gas that contributes to global warming, but nobody has measured the impact until now. The scientists measured carbon levels in plant and soil samples collected from 13 green roofs in Michigan and Maryland over a two-year period. Their study is slated for publication in the October issue of Environmental Science & Technology. Here are some facts and tips on green roof:Green roofs last longer than conventional roofs, reduce energy costs with natural insulation. They absorb storm water, potentially lessening the need for complex and expensive drainage systems. Green roofs improve air quality and help reduce the urban heat island effect. About 15% of heat in a building can come through roof, which can be eliminated by having a green roof. Green roof technology extends roof life and is effective for sound insulation in the building. Many green buildings in India are also adopting such roof-tops dens. GBC building in Hyderabad is among them."May God bless yOu and have a great time.
