Two Indianapolis businesses are partners in an effort to create a more beautiful, environmentally friendly scene at a Far-Northside home for seniors.

The roof gives residents a green space to look at from the sitting room and provides environmental benefits, said Tina Gaines, Firestone spokeswoman.

The home is at 2345 W. 86th St., near St. Vincent Hospital.

Benefits of the roof include catching rainfall, which will lessen the burden on the sewer system, lower heating and cooling costs, and protect roofing materials from weather, Gaines said. It also provides a habitat for birds and other wildlife.

Workers prepared a modular tray on the roof in the morning and then installed plants in the afternoon.




"Green" roofs help reduce global warming
"They reduce heating and air conditioning costs..."

WASHINGTON - "Green" roofs, those increasingly popular urban rooftops covered with plants, could help fight global warming, scientists in Michigan are reporting. The scientists found that replacing traditional roofing materials in an urban area the size of Detroit, with a population of about one-million, with green would be equivalent to eliminating a year's worth of carbon dioxide emitted by 10,000 mid-sized SUVs and trucks.

Their study, the first of its kind to examine the ability of green roofs to sequester carbon which may impact climate change, is scheduled for the Oct. 1 issue of ACS' Environmental Science & Technology, a semi-monthly journal. Kristin Getter and colleagues point out in the new study that green roofs are multi-functional. They reduce heating and air conditioning costs, for instance, and retain and detain stormwater.

Researchers knew that green roofs also absorb carbon dioxide, a major greenhouse gas that contributes to global warming, but nobody had 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. They found that green roofing an urban area of about one million people would capture more than 55,000 tons of carbon, the scientists say. That's an amount "similar to removing more than 10,000 mid-sized SUV or trucks off the road a year," the article notes.
