-I've managed to upload the image of the geographic location
-I've represented two of Val Melaina's court disposed buildings
-I've represented Porta di Roma’s school on via Giuseppe de Santis 3
-I've setted on sunlight (at 5/04/2012, h14:00)and setted shadows on
-I've uploaded in the scene a model of my project showing how I've studied a building's disposition that let most part of south facades illuminated by direct sunlight in order to exploit solar radiation for heating, even on December 21th, when sun path is the lower of the year (it's the situation showed in the image). Software application shows that study based on distances and heights of buildings works.
