Here is a great example of a green roof being used in Indianapolis, IN at the pharmaceutical company Eli Lilly. The green roof spans 20,600 sq. ft. and is not only aesthetically pleasing to their employees, but saves the company money in terms of heating and cooling as well as saving the Indianapolis area money by diverting 446,000 gallons of water per year.
