Evaluation of Sustainable Roof from Various Aspects and Benefits of Agriculture Roofing in Urban Core

The purpose of this paper is to discuss the environmental load of three types of roofing systems, and to clearly identify the advantages and disadvantages of each by measuring various environmental factors. The three roofing systems each contain sustainable advantages to being “green.” First, roofing can be designed to collect rainwater and reduce potable water usage. Second, adapting a green roof can not only effectually decrease the amount of stormwater runoff, but also mitigate the heat island effect, extend roof life, and improve thermal and sound insulation performance. Third, agriculture roofing includes some of the benefits of green roof, and, as a by-product, food can be grown in an urban core, reducing the carbon footprint. This paper compares and evaluates these three systems to validate the benefits to society and environment.
