The house is in Galileo Ferraris street. I took the first picture on Thursday the 13 th and Friday the 14 th. Through the 3dD created with Vasari I studied the progression of the sunlight on the house in different hours during the day. I took the first picture at 12:00 and is visible that the north-west wall is quite illuminated and the sud wall too so at this time of the day the sud wall should be covered. I took the second picture at 15:00 and is visible that the north-west wall is in shade, even becouse of the near biulding that covers all the west part of the house, but in the west this isn’t a problem becouse there aren’t windows on this wall. The sud is enough illuminated. At 17:30 the north wall is illuminated, but there is some shade made by the trees situated along the street and the Lungotevre. The sud is alway quite illuminated and the north is quite in shade so this is the only part that can give some problems.
