The goal of this project is to determine where it is economically feasible to have a green roof and where it will become cost effective. We will compare the energy savings in four cities of varying climates to discover where a green roof will become economically feasible and how long it will take to pay for itself compared to a conventional roof. The four cities that we have chosen are Los Angeles, Houston, Miami, and New York City. Los Angeles was chosen for its dry hot climate, Miami for its hot humid climate, Houston is a slight combination of Los Angeles and Miami, and New York for a northern temperate climate. We have also chosen a standard building size of 55’x55’ to be hypothetically placed in each city. After researching the climates in each city, the cost of heating the buildings and the cost of a green roof, we took those numbers and calculated how long the payback period was for each city. We found that the payback period for the cities ranged from 300‐400 years and that in southern warmer climates is best for a green roof.
