On the solar energy side, plenty of studies have focused on improving the accuracy of solar assessment
on building rooftops by developing software and algorithms [10, 11] and using detailed 3D building
models made in Rhinoceros [12] or based on LIDAR (Laser Imaging, Detection and Ranging) data [13,
14]. However, similar to the building energy modeling, when they are applied to the urban scale, the
mutual shading influence and resulted suitable roof areas for solar production is rarely considered [10, 15]
and enthusiasms solely on accuracy pays a price of more computational time, especially at the urban scale.
The urban scale coupling modeling for solar buildings shares the same challenges of the two modeling
aspects, and the data management is even more complex. The exploration in the coupling modeling just
started with measure data or simple correlations, with more emphasis on solar potentials [10, 16].
