The plant-covered surfaces reduce heating and air conditioning costs by ten per cent or more. The also reduce rainwater runoff, carbon emissions and have been proven to counteract higher city temperatures.
The â€œurban heat island effectâ€ is a new discovery attributes heat-absorbing city surfaces for raising air temperatures by up to 8 degrees in comparison to surrounding areas.
The U.S. is seeing its green roofs grow by 125 per cent each year. An astounding 2.5 million square feet of Chicago's downtown roofs are covered in plants.
