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.
