This is my first time with the program "project vasari", in the image we can see the house complex where i live (i'm in the center one), with the vasari program we can see the sun when touch the building and when there is shadow projected from other buildings.

Project Vasari is a program made to analyze the performances of a building; but it is necessary to test the reliability of the simulation by verifying some data we can compare to a real situation. This is why our first step consist in comparing the virtual and the real shadows of the building before going on with the analysis.
