Lab_6 2_Es Via Eugenio Barsanti, Roma

In this second exercise, I have studied my building and, in particular, my room's facade to calculate the solar radiation.  For this reason, I have added some elements that I think will be decisive for the study of the solar radiation: the ledge, the balconies and a part of the front jutting out from the rest.

I have analyzed the solar radiation in winter and in summer to understand how the building works during the coldest and hottest periods of the year.

I have considered the period of June-September and also the last days of July, maybe the hottest days of the year. In summer, the front seems to be warm and comfortable. In fact, it is totally blue, except for some parts of the floor of the balconies. Actually, in summer staying at home is intolerable because it is very hot. Maybe, part of the heat is caused by the asphalt all around the buildings. As we see in the image below, the asphalt goes from red to yellow and it means that it absorbs a lot of heat, especially in summer

.

I have studied also the period between December and March and in particular the coldest days of the year, at the end of January. In winter, the inferior part of the facade is cold, while the last floors are hotter. It is interesting to observe how the buildings work with and without the presence of some elements (like, for example, the balconies). In fact, these elements influence a lot the shading and, in consequence, the effect of the solar radiation. Without balconies, the superior part of the building will be very hot.

It is also interesting to notice the flat roof: it is completely sunny both in summer and in winter. For the people that live in the apartment on the last floor it is a problem.

The study of the solar radiation allows us to understand if our building is proofed in the correct way or not. We can see some problems: for example we can notice some missing parts of plaster under the balconies, caused by the humidity, and the changing of the plaster's colour under the balconies for the shading.
