Lab_6 Es_2 Solar Radiation Analysis_ via di monteverde_ Martina Pieri

Compared to the previous excercise, some elements has been added and they're balconies and recessed parts. Their addition defines a change of the solar radiation previously done; in fact also the shape of the shadows seems new. The colours that we can see in the pictures defines the the degree of exposure of the sun rays. My building is surronded by other tall buildings so it's difficult to receive a lot of solar radiation. The periods that I analyzed are the 21st of June and the 21st of December.

A. SUMMER SOLAR RADIATION

     I choose the 21st of june and we can see that only the side that is towards South-East receive enough solar radiation( The yellow, red and orange areas).      The people that lives in the lower  floors have the little advantage that their apartment is cool (purple and blue areas) so they don't need a cooler          instead of the one who live on the top of the building.

B. WINTER SOLAR RADIATION

      In winter we had the opposite situation. The favourite person are the one who lives on the top because they receive the few solar rays. As I sayd in the previous exercise I live in the basement and I had a garden. My place is totally covered in winter so we have a very cold apartment and only thanks to the radiators we can heat up the apartment. As we can see the garden is totally blue and it explain the low exposure and the presence of a high moisture expecially on the conjuction of the wall with the garden's surface.

CONCLUSIONS

What seems clear is that areas like mine, that have high population density and therefore have a type of building, such as "palazzina", hardly have a good exposure to the sun. This because the buildings are close together and the short distance is not enough to illuminate the entire building. From this comes the high moisture that causes numerous effects such as detachment of plaster, black spots and moss formation.
