The green roof calculator “Green to earn green”

Ever won­dered how much money and energy you could save if you decided to have a green roof where you live? A cal­cu­la­tor by the Amer­i­can Rivers orga­ni­za­tion called “Green to earn Green” will answer this ques­tion eas­ily. You just have to locate or type your address when asked and then select the area in which you want to apply the green roof. For exam­ple, accord­ing to them, a green roof installed at Madi­son Square Gar­den could save $ 190,524 (sav­ings on heating/cooling costs and roof repair annu­ally) while also sav­ing 3.4 mil­lion gal­lons of water (storm water runoff kept from pol­lut­ing rivers).

Have fun try­ing it for your own address and see­ing the poten­tial energy ben­e­fits a green roof could bring.
