The studied area is located in Viale di Villa Pamphili, in Monteverde Vecchio district (Rm). The analysis of the shadows refers to the building in Viale di Villa Pamphili 61. This building is an irregular volume and it is composed by six floor and has a garden on the ground floor, at the street level. The shadow analysis deals with the study of the west front in different moments of the day. The pictures were taken in the day March 15, 2014 at strategic times : at 8.30 a.m. , 1.00 p.m., and then at 6.00 p.m. In the morning, at 8.30 a.m., we can see that the analyzed front is completely shaded because the sun shines on the opposite side of the building. At 1.00 p.m. the sun is high in the sky, so the west side of the building is hit by the sun, but the body of the building that sticks out reflects his shadow on the body behind. So the left part of the front appears more shaded than the right one, that is mostly lighted. At 18.00 the building at the other side of the street reflects his shadow on the west front that appears lighted only in his upper part. Moreover In the garden at the street level there is a tall pine tree which reflects his profile on the building, but his shadow gets confused by the others. The tall pine create a shadow on the building when it is hit by the sun, after 13.00 p.m. I have noticed that many shadows are caused by the irregoular shape of the building which project on his face the shadows, moreover during the afternoon, when the sun is going down. My flat is located at the sixth floor of the building. All the most important room of the house (bedrooms and livingroom) are directed to sud-east so receive a good daylight in winter, but during the morning summer the beedroms collects too many light and also become too warm. The service areas (kitchen, bathrooms) doesn’t need a particular light so they are directed to nord-west.
