Abstract
This research project focuses on testing different types of roofs, all made with different materials, and recording what type of roof works best to mitigate the urban heat island effect. The specific goal of this research project is to run tests which demonstrates that buildings with cool roofs result in cooler interior temperatures, therefore reducing the amount of energy needed to cool the building and reducing the amount of resulting carbon emissions.Tests were run using a small model house with corresponding removable model roofs. Two trials were conducted using four different roofs; Trial 1 focused on comparing the energy usage of a steep sloped black shingled roof with a steep sloped gray shingled roof, Trial 2 set focused on comparing the energy usage of a control black shingled roof with a green roof. The second phase of research focused on comparing the amount of water runoff between the green and control black roof. Results from Trial 1 showed that on average, the gray shingle roof consumed .22 kWh, and the black .27 kWh, resulting in an 18.51% reduction of energy usage. Results from Trial 2 showed that on average, the green roof consumed .20 kWh, and the control .23 kWh, resulting in a 13.04% reduction in energy usage. When pouring 20.00 L of water on each roof, the green roof had an average runoff of 8.76 L, and the control 19.05 L, resulting in a 51.45% reduction of water runoff and suggesting green roofs have a lower amount of water runoff than traditional roofs.
