Abstract.

We explore the relation between urban street networks’ characteristics particularly circuitry, street orientation entropy, road network length, mean and standard deviation of the streets’ orientations, on the one hand, and the buildings’ orientation entropy along with the mean and standard deviation of their orientations, on the other hand, in order to quantify their effect on the city’s solar potential. The latter is shown to be controlled by the constrains of land form on the streets and buildings’ orientations. These statistical measures of the road network reveal the interplay between the built environment’s design and its sustainability
