LOCATION DESCRIPTION
Located in the southern side of the urban area of Rome, the site in Divino Amore confronts with such a green and open scenery that finding a proper shading situation resulted problematic. Difficulties were enhanced by great distances between buildings and their inappropiate mutual positioning. Residences are informal and in some cases unlawful.
VASARI: STEP BY STEP PROCEDURE
1. Download and install Autodesk Vasari on your computer. It may cause some problems perhaps due to internet connection or missing files in the downloading phase. We suggest you to overcome this by trying multiple times until no error messages appear.
This is the opening loading image. If you see it you will be sure that the installation has been successfull.
2. Run the program. This is the main page.
3. Click on New metric in order to work with metric units.
4. Home page will open. On the left you will find the properties box just like other Autodesk application, as for instance Autocad.
5. Click on the Manage button on the upper section of the screen.
6. Click on Project Units and set the wanted metric formact and the right rounding as shown in the following pictures.
7. On the Analyze section select the Location button in order to set the right location for the project. Boston, Massachusetts in set as default. Switch to any location you need by writing in the search bar your project address. You will be automatically tranfered to the chosen place wich is pointed by the red pin. The orange one indicates the nearest weather station. Make sure to pick it not necessarily by distance but by reliability. For example we chose Ciampino's weather station as suggested during the course lesson. Also make sure to set off the Use Daylight Savings Time option.
8. Once you zoom in the map will turn into satellite mode. Move the red pin around to position it most precisely.
9. Click on Import Site Image, then set the level you want to place it in and click Import.
10. Start setting the project by clicking on the Set button on the upper left edge of the screen.
11. Select Create Mass and draw the shape you need using the drawing tools in the bar that will automatically appear. Once you are satisfied with the resulting shape select Create Form and extrude it to make a volume. Once you have finished click on Finish Mass to confirm or Cancel Mass to delete.
12. Set the view mode (ortographic or perspective) in the Views section of the Manage bar.
13. Click on Sun Settings, then in the Settings section set the right date and time.
14. Set the shadows on or off by clicking the Shadow button. You can do the same with the Sun Path. You may decide to make your model realistic (like we did) by the option Ray Trace located in the square box icon on the left of the Sun Path.
15. Click the Camera button in order to place the camera on the wanted spot and turn it to make it face the right side.
16. Grab a screenshot according to your computer keyboard.
RESULTS SITE DIVINO AMORE
9.07 A.M.
4.36 P.M.
CONSIDERATIONS
It is evident that the East facade of the building is much more shaded than the west side. This is due to the particular configuration of the site and the positioning of the two buildings. As for the afternoon analysis we needed confirm for the delay of the shadow wich appears particoularly slender. Further studies will specificate the shape of the shadow caused by loggias and balconies.
In order to cross the data we got from Vasari and confront them with those from other programs, we decided to verify the results on Sketchup.
What we got was unsatisfying and disappointing. The application's lacks in precision and details gave us uncorrect images, as shown.
SECOND LOCATION DESCRIPTION
The second location we chose, Parrocchietta, is located on the south west side of the city, within the G.R.A.. It is a medium density residential neighborhood whit a green percentage slightly lower than the first one and has a peculiar ground conformation: all houses stand on a high slope hill wich deeply infuences the shading system.
We considered a single block with two rows of buildings, one on street level, the other standing on a high podium.
RESULTS SITE PARROCCHIETTA
8.02 A.M.
3.14 P.M.
CONSIDERATIONS
By confronting the analysis of the buildigs it is clear that although both sites have the same orentation the second one appears much darker: it is very likely due to the narrow form of the in-between street and the height of the two buildings and the podium.
We noticed that especially in the early afternoon the East facade starts to be in shade, while the podium starts recieving light.
SOLAR ESPOSITION IN THE URBAN CONTEXT
In order to get a better analysis of the solar exposition in the urban context, we decided to proceed with the second study. It basically consists of a little and narrow courtyard between higher and lower buildings. Such courtyard actually belongs to the latter.
It is very cosy space and is mostly used as a passage through the buildings, but often children who live there take advantange of it as a pkayground. Therefore the situation is not confortable at all: in winter it receives no sunlight because of the big relatively high-rise building situated at the East, and the three buildings at the West.
Summer gives no better feedback since sunlight comes in this space only in the hottest hours of the day. It is so narrow, humid and dark that vegetation cannot survive.
We dare to say that the architects designed this court like a shaded corridor without thinking about the possible other uses of this outdoor space.

Dom, 22/03/2015 - 15:19Open Vasari software and select NEW METRIC to start the project
Select MANAGE ---> PROJECT UNICTS: clicking here, we can change the units of measure from millimeters to meters.
Now clicking on ANALIZE ---> LOCATION we can state the geographic location of the project: Vasari uses in fact an Internet mapping service to visualize the project location by its address or the longitude and latitude. This setting is helpful to develop shadows for solar studies and rendered images.
This is an example: the arrow indicates the point where you need to enter your address
After importing the image on level 1, select MODEL ---> CREATE MASS
and then click on MODIFY | PLACES LINES to create the outline of the chosen area
and finally on FINISH MASS
Now to extrude the volume, click on MODIFY | FORM ---> SOLID FORM and set the height of the building.
At this point we've analyzed the buildings orientation in order to understand how much direct sunlight they receive.
Clicking on the icon of the sun at the bottom of the page, SUN SETTINGS, we've selected SUN PATH ON and we've activated a sun model which can be moved around the path of the sun. Selecting SHADOW SETTINGS, next to the first one, and then SHADOWS ON, it's possible to start up the shadows based on the orientation of the sun during the day.
Besides, in SUN SETTINGS, we've selected Multiday Solar Study during winter, spring, summer and fall.
We've focused our particular attention on my building's facade facing East and on the other one belonging to the near building facing North.
9 AM
12 AM
3 PM
17 PM
Selecting VISUAL STYLES: REALISTIC WITH EDGES icon, at the bottom of the page, we've chosen RAY TRACE view and we did the screenshot of different views of the chosen building.
Our study is focused on two buildings (which follow the type of row houses) located in Via Bonaventura Cerretti, 55 and composed of five floors. From the analysis of sunshine we've noticed that North facade is shaded for almost all day until 5 pm, when the left part of the second building receives sunlight. The facades facing South, instead, are affected by direct sunlight for all day, from 9 am to 5 pm. Also during the four analyzed seasons, we've observed that North facades are always and totally shaded except the right facade of the first building, which is affected by direct sunlight on summer. For this reason, we've noticed disadvantages and advantages: in fact during winter the apartments are very cold (especially kitchen and living room, talking about my flat) while during summer they're fresh enough.
Talking about photos selected for our exercise, the picture taken at 12 pm isn't perfectly correspondent to Vasari's model, unfortunately; also because the street in which they're taken, being very narrow, hasn't allowed to show all analyzed facades, whose view is strayed. However, we've tried to keep us as faithfully as possible close to the model of the software.

In questa prima esercitazione studieremo il soleggiamento e l'ombreggiamento di un edificio situato a Borgo Podgora, frazione del comune di Latina.
Dopo aver aperto il programma Vasari, selezionare New Metric per aprire un nuovo foglio.
Per definire la posizione geografica del progetto, aprire Location tra le opzioni di Analyze e inserire l’esatto indirizzo del sito. Una volta scelta la stazione metereologica più adatta, e spuntata l’opzione Use Daylight Savings time, importare l’immagine del luogo sul livello 0 di lavoro cliccando su Import Site Image.
Successivamente scegliere l’unità di misura andando su Manage – Project Units.
Per iniziare la creazione di piante e volumi, andare su Model e da lì selezionare Create Mass.
Selezionando le superfici si possono modificare le dimensioni grazie alle frecce che indicano il verso di spostamento, oppure inserendo le quote manualmente. Per creare un solido, dopo aver selezionato ogni pianta, usare il comando Create Form – Solid Form, (oppure Void Form qualora si volessero realizzare delle bucature/vuoti) inserendo le quote altimetriche dei vari edifici.
Con il comando Finish Mass salvare le modifiche dei solidi.
Per inserire le ombre selezionare dalla barra in fondo il comando Shadows On, e per impostare l’orario e il giorno cliccare su Sun Path – Sun Settings.
Infine, per ottenere le varie immagini, andare su Manage > Camera.
Studio dell'edificio
L'edificio preso in cosiderazione si trova a Borgo Podgora, in provicia di Latina. Questo Borgo è il primo nucleo abitativo edificato durante la Bonifica Integrale, concepito come iniziale villaggio operaio, che è costituito da un centro urbanizzato e una vasta area agricola appoderata. Attualmente il Borgo è in grande espansione urbana grazie alla costruzione di molte case in linea e case a schiera.
L'edificio è situato in una zona che si sta densificando velocemente ed è circondato da altre costruzioni di diversa altezza.
Si tratta di un blocco di case a schiera, le cui singole unità abitative si sviluppano su due piani. Il fronte principale è orientato a sud e presenta piccoli giardini privati e gli accessi alle abitazioni.
Attraverso l'analisi del percorso solare si può notare che solo le abitazioni alle estremità dell’edificio sono ombreggiate: la casa a destra ha esposizione sud-est perciò il prospetto ad est è totalmente ombreggiato durante il giorno mentre la facciata sud passa gradualmente da una situazione di ombra parziale a una condizione di soleggiamento fino a sera; la casa a sinistra ha orientamento sud-ovest, quindi il suo prospetto sud è sempre soleggiato mentre il prospetto ad ovest passa da una situazione di ombra fino a metà pomeriggio per poi essere di nuovo in ombra durante il tramonto, momento in cui l’edificio adiacente lo scherma dai raggi diretti del sole.

Ho analizzato un edificio posto sull’intersezione tra Via Giulio Aristide Sartorio e Via Raffaele Sorbi nel quartiere di Tor Marancia, Roma. La facciata principale del mio edificio è esposta a Nord-Ovest. Abitando al terzo piano la casa risulta: in estate ombreggiata fino alle 16:00/17:00, quindi al riparo dall’irraggiamento nelle ore più calde, mentre in inverno la facciata è quasi sempre in ombra rendendo la casa piuttosto fredda.
Per la consegna ho preso in cosiderazione 2 orari:le 11:30 e le 17:30

Dom, 22/03/2015 - 13:57Lab 6: TESTING SHADOWS
Step 1: Start a new project and localize it
Open Vasari and select NEW METRIC to start the project.
Select MANAGE > PROJECT UNICTS: here it’s possible to change the units of measure from millimeters to meters.
Click on ANALIZE > LOCATION to specify the geographic location of the project. Vasari uses in fact an Internet mapping service to visualize the project location by searching on its street address, or the longitude and latitude of the project. This setting is useful to generate shadows for solar studies and rendered images. Also, don't forget to select the nearest weather station, with the altimetric features more similar to those of the project's site.
Finally, IMPORT SITE IMAGE on the level one.
Step 2: Drawing the buildings
After importing the image of the project’s site, click on MODEL > CREATE MASS
and select MODEL LINE > DRAW ON WORK PLANE to draw lines on the actual work plane.
Now it’s possible to draw precisely the plan of the building directly from the site. To extrude the volume, click on MODIFY | PLACE LINES > CREATE FORM > SOLID FORM, and then set the height of the building.
Step 3: Sun path study
It’s possible to access the sun and shadows settings in the lower panel of Vasari: by clicking on SUN PATH ON you will activate a sun model which can be moved around the path of the sun based on your geolocation. Clicking on SHADOWS ON it’s also possible to activate shadows and see when the model is shaded or shades the sunroundings.
Step 4: Our exercise
We have focused our attention on the buildings at the intersection of Via Andrea Mantegna and Via dei Georgofili, in order to understand how much direct sunlight they receive.
In SUN SETTINGS, first we have setted the most significant moments of the year.
WINTER SOLSTICE
09:00 12:00
15:00
The sun path is lower, so we can observe that during the North-West facades of all the buildings never receive direct sunlight. Also, the building that we called a is always shadowed, because of his position, in fact the building b and c cast their shadow over it for almost all the day: this looks like a problem during the coldest months of the year.
SUMMER SOLSTICE
09:00 12:00
15:00 17:00
The sun path is higher, so the South-West facades receive direct sunlight basically during the central hours of the day, which are also the hottest one.
AUTUMN EQUINOX
09:00 12:00
15:00 17:00
Here the sun path is mostly the same of the day we analyzed (20 March), comparable to the Spring Equinox, so the situations are very similar.
We’ve also made a consideration about the part of Via dei Georgofili that our buildings overlook: it is a cross street of Via Andrea Mantegna, so it’s not very large and the buildings often cast their shadows on it during the equinoxes and winter solstice. Anyway, we have observed that, during the summer solstice, the street receives direct sunlight in the central hours of the day, which are also the hottest: this might be a problem, because the high temperature of the asphalt can seriously influence the temperature at the street level.
20 MARCH 2015
we’ve picked the date (20 March) and the different times of the analysis (09:00, 12:00, 15:00, 17:00) in order to compare the shadows in different moments of the day.
09:00 12:00
15:00 17:00
Then we compared the render perspective views - obtained setting a proper view with the FULL NAVIGATION WHEEL tool - with the photographic surveys taken on the selected date, in order to verify the actual correspondence.
12:00
15:0017:00
So, our study is basically focused on the three buildings on Via dei Georgofili, the two ones on the left, one of five and one of six floors, and the third one, on the right, with a bigger facade and definitely taller, with eight floors.
What we noticed is that the two buildings on the left side present some parts of the facades that, during our day of study (easily assimilable to the spring equinox), never receive direct sunlight: more precisely, the whole facades on Via Andrea Mantegna and the recessed parts of the facades of Via dei Georgofili, because of their position, in fact they are exposed to North-West.
On the other side, the South-West facades receives obviously more direct sunlight, in the speific during the central hours of the day, approximately beetween 11:00 and 16:00, until the frontal building, which is taller, casts its shadow over them. Also, the North-East facade of the taller building on the right receives direct sun only during the first few hours of the morning, so probably the apartaments that overlook here don’t have the same exposition of those one located on the South and West front. This could be an advantage during summer but also a disadvantage during the coldest period of the year.
