In this model, the 3D urban environment engine transformed the building footprints and topography
into 3D Raster files respectively, and then used the “Plus” tool in ArcGIS 10.2 to generate a combined
Raster file to represent the 3D urban environment. The “Area Solar Radiation Tool” in ArcGIS 10.2 used
the combined Raster file as its input and simulated the solar energy potentials on building rooftops and
grounds on hourly, monthly, or annual bases (Fig 2b), depending on the analysis purpose.
