We decided to analyze the shading in both of ours home buildings, because we have noticed that they are very different in their conformation and the area where they are located.
The one situated in Marconi, Via Eugenio Barsanti, it's a building of 8 floors surrounded by similar edifice; the second located in Monteverde, Via Fabiola, it's a building of 4 floors surrounded by a big empty space and a tall bell tower.
The analysis is made by the help of the program Autodesk Vasari.
After we downloaded Vasari the first step was opened it and select the option 'New Metric'.
After click this option you will see the next screen where you can set up (left on top) the option 'Location' that it is necessary to locate the two different buildings. In the consecutive images you can see our cases.
The next step, after 'Import' the image (we can see the option in the lower right), is to 'Create Mass' that creates and rapresents the measures of the both buindings. We can find the set up 'Create Mass' in the toolbar.
After the creation of the mass, we can use the program Vasari as a shadow simulator by clicking, in the low toolbar the two symbols that rapresents one the sun movement, and the other the shadow that the surrounding buildings, and that the edifice itself creates in relation with the settings of date and time.
With this command the screen that opens is the route of the sun automatically set to 12 and a random date. We can modify those two options by clicking on it and selecting the date and time we are intrested to. We have done this operation in the second image, setting the time at 10.30am and the 23 of March.
The result of the shadow simulation can be observed in the first two images for Marconi location at 4.00pm and in the last two images the Monteverde location at 10.30pm.
Conclusions:
In the Marconi area, the demographic background and then the size and the approximation of the buildings, allows just a few hours of direct sunlight on buildings, due mostly by the continuous projection of the shadow of the surrounding buildings.
In the Monteverde area, the almost empty background shows how the building enjoys a continuous sunshine link only to the route of the sun during the day. Neither the close tower bell (30 metres tall) makes its shadow over the building.
The shading is an important architectural character that should be considered during the project phase in order to consider the wellness of the inabitans and the concequences on the buildin itself.

Andremo a spiegare il processo effettutato per riprodurre un modello 3d con annesso studio del sole nel corso di solstizi e degli equinozi.Tre foto,scattate in tre orari differenti,sono associate a tre modelli dello stesso edificio avendo cercato di ricreare le stesse condizioni ambientali. Si è preso in considerazione uno stabile in Via Vito Sinisi a Roma in zona Cassia. L'edificio fa parte di un conprensorio di due palazzine una accanto all'altra.La palazzina che andiamo ad analizzare è la palazzina A. Davanti alla palazzina è presente un ampio spazio libero dall'ingombro di edifici.La palazzina B si accosta alla palazzina A sovrastandola di almeno 4 metri a causa di un dislivello nel terreno, Entrambe sono di 5 piani più super attico.
Si procederà per punti:
1 Per prima cosa apriamo vasari e clicchiamo su NEW.
2 Modificichiamo le unità di misura attraverso il comando project units.
3 Abbiamo impostato l'area di lavoro con il comando location inserendo l'indirizzo dell'immobile preso in esame.
4 Importo l'immagine su Vasari dell'area di lavoro ( l'edificio preso in esame è indicato con un pallino rosso)
5 Siamo passati poi alla realizzazione dei corpi di fabbrica presenti nell'area attraverso l'uso dei comandi: Modify,Create Mass, Line, Finish Mass.
6 Attraverso il comando shadows on abbiamo inserito le ombre sugli edifici e con il comando sun settings abbiamo impostato dversi orari nei giorni dei solstizi e degli equinozi in modo da studiare il comportamento del sole nell'arco dell'anno.
SOLSTIZIO D'INVERNO
SOLSTIZIO D'ESTATE
EQUINOZIO D'AUTUNNO
EQUINOZIO DI PRIMAVERA
7 Confrontiamo quanto risulta dal modello con delle foto scattate nelle medesime ore in cui è stato impostato il modello.
23 marzo alle 9:00:
vista aerea
vista frontale e fotografia
23 marzo alle 11:30:

vista frontale e fotografia
si nota che la facciata principale dell'edificio, orientata a sud-ovest, in ogni periodo dell'anno si trova completamente in ombra nelle prime ore della mattina. Dalle 10:30/11:00 comincia ad essere illuminata dal sole. Dalle ore 12:00 in poi si trova illuminata e riscaldata dal sole in ogni periodo dell'anno. L'edificio posto attaccato al fianco destro della palazzina considerata, al contrario di quanto sembrerebbe, non incide particolarmente nell'ombreggiamento di quest'ultima se non nelle prime ore della mattina. Questo grazie al suo orientamento e alla sua posizione che non ostacola l'arrivo dei raggi solari nelle ore più calde della giornata.

Lab 6 : First exercise
Team Benoit_Bostyn
TUTORIAL
Step 1 : Configure the file
To start a new project, open Vasari and in "Projects" select "New Metric".
First of all, go in "Manage" (1), then select "Project Units"(2). There you can put the measure system in meters (3).
When you've done that, click on "Analize" (4) and "Location" (5) in order to find the place of your building. Here you will select the nearest weather station and then go on "Import Site Image..." (6) so as to have the shape and the orientation of your buildings.
Step 2 : Build !
The first step is to select "Model" and then to click on "Create mass". It will open a new tab where you will click on "Model Line". Don't forget to select "Draw on Work Plane" before you start to draw.
Then, when you have the profil of your building, click on "Create Form" and select "Solid Form" to start to extrude the volume (the other choice, "Void Form" could help you doing your volume by doing holes in it).
When you got your volume, you just have to drag the arrows to change the measures. You will also see digits on the edges, by clicking on it you can enter precise heights (here 30m).
Step 3 : Analyze your project
When you've done your volume, you just have to click on "Sun Path On" and Shadow On" to create the light environment of your building.
Simply by clicking on "Sun Settings..." you will find a window where you can configure the date and the hour for your sunlight and shadow.
Then well done, because you've successfully manage to do your first solar analyse with Vasari !
OUR PROJECT
As an example, we've choose our block of flat, via Francesco Grimaldi. We live there at the 5th floor and we have a good sight on the inner courtyard. We were curious to see how it works in here :
So first, we "build" our home with the method seen before and put the light and shadow at 9:00am and 1:00pm the 23/03/2015.
Then we have taken two photos of the courtyard at these differents hours to check everything :
AT 9:00 AM
AT 1:00 PM
And so it works well, and as you see, we are quite lucky : our balcony is facing south and have the sunlight at the best hours of the day !
Thanks for the reading.
