Previous studies suggest potential for energy savings through cool and green roofs, but do not always consider the many factors that affect potential savings or the relative advantages of different technologies. To further investigate these factors, a tool has been developed to allow architects the ability to quickly assess the energy-saving potential of different roof systems. A first principles heat transfer model has been developed for each of the roof technologies, with particular care for green roof heat and mass transfer. Experimental data from Japan and Florida validate the models by predicting roof surface temperature. This model is incorporated into the existing MIT Design Advisor to allow users the ability to include roofing systems in their energy analysis of a building.
