6. Click on "Sun path on" to set the right time and date, then proceed to "Display shadows"

7. Take some pictures with the virtual "Camera" from different points of view in different hours of the day

ANALYSIS

My study area is located in Via Manlio Torquato, a side street of Via Tuscolana, in the Appio Latino district in the eastern part of Rome. 

The neighborhood  is characterized by similar complex of buildings with an inner court of about 8/10 floors.

I live at the last of an 8th floors building who has the main facade exposed to N-W and the back facade exposed to S-E (img. 1), so the building is directly enlightened in the back side from dawn to dusk; while the main facade receives only scattered light. 

For the analysis I've studied the main facade and the inner court in three different hours of the day: 10:00 a.m, 02:00 p.m. and 05:00 p.m. (img. 2-7-10).

In the morning at 10:00 the inner court and the back side of the building is completely enlightened (img. 3-4) while the main facade is entirely shaded (img. 5-6).In the afternoon at 02:00 the main facade is shaded too (img. 8-9) while at 05:00 p.m. starts receiving a little direct light (img. 11-12).

Every apartament runs the entire length of the building so receives light from both sides. My apartment is composed with two bedrooms exposed to N-W and a bedroom, the kitchen and the bathroom exposed to S-E. Thanks to this analysis I've realized that these rooms are warmer than the others because receives direct light all the time, and so in winter the two bedrooms exposed to N-W are really cold. Instead in summer the apartment is really hot because receives a lot of light from both sides and it doesn't have any sort of shielding.
