Step 3 _ Select the units from the "project units" window (our case is lenght meters).
Step 3 _ Selezionate l'unità di misura dalla finestra "project units" (nel nostro caso "lenght -> meters").Screenshot 2015-03-19 17.14.04.png

Step 4 _ To conduct a proper study on shading and lighting you must take into account the position of the building analyzed, then click "location" icon on the "analyze" bar.
Step 4 _ Per realizzare uno studio corretto sull'ombreggiamento/irraggiamento bisogna tenere in considerazione la posizione dell'edificio analizzato. quindi cliccate il comando "location" nella barra "analyze".

The house that we studied is located in Fidene - Rome - in Via Ortignano; this presents a lot of buildings of different heights, from 3 to 6 floors. In our case it's a building of 5 floors around 23 meters tall, next to it there are both a taller building (left side) and shorter (right side). With our analysis we've studied the response of the building to different hours of the day and different seasons.

L'abitazione che abbiamo studiato è situata nel quartiere Fidene - Roma - in Via Ortignano; questa presenta edifici di varie altezze tra i 3 ed i 6 piani. Nel nostro caso si tratta di una palazzina di 5 piani alta circa 23 mtetri e ad essa si affiancano un edificio piu alto (sul lato sinitro) ed uno più basso (sul lato destro). Con l'analisi svolta abbiamo studiato il comportamento dell'edificio in più ore della giornata e durante stagioni diverse.

The result of our study is:

WINTER _ The facades Northwest and Southwest, because of the unfavorable position and proximity to the other buildings, remain in the shade for most of the day. The front Northeast is irradiated only in the early morning light, unlike the Southeast who enjoys sunlight throughout the day.

SUMMER _ A Northwest the building can enjoy the sunshine from early afternoon until sunset, hours when the facades North-East and South-East are shaded. The proximity to the building on the left side creates shadows on the facade Southwest throughout the day.

In conclusion we can say that the more advantaged facade is the Southeast as it receives sunlight during the cold winter days and resulting instead cooler (because shaded) in summer. The lack of buildings on the southern front is in favor of such a result. As for the north solar radiation is unfavorable as it occurs only during times warmer summer (from 12 to 16). The lack of sunlight in the facade Southwest is for the winter a disadvantage, but the summer is rather advantageous.
 

Dallo studio effettuato è risultato che:

INVERNO _ Le facciate Nord- Ovest e Sud-Ovest, proprio per la posizione sfavorevole e per la vicinanza agli altri edifici, rimangono in ombra per gran parte della giornata. Il fronte Nord-Est è irraggiato solo nelle prime luci del mattino, a differenza del prospetto Sud-Est che gode di luce solare per tutto l'arco della giornata. 

ESTATE _ A Nord-Ovest le abitazioni possono godere della luce solare dal primo pomeriggio fino al tramonto, ore in cui le facciate Nord-Est e Sud-Est risultano ombreggiate. La vicinanza all'edificio sul lato sinistro genera ombre sulla facciata Sud-Ovest durante tutta la giornata.

A conclusione possiamo affermare che il fronte più avvantaggiato è quello Sud-Est in quanto riceve la luce solare durante le fredde giornate invernali, risultando invece più fresca (perchè ombreggiata) nel periodo estivo. La mancanza di edifici sul fronte Sud è a favore di tale risultato. 
Per quanto riguarda la parte Nord l'irraggiamento solare è sfavorevole in quanto si presenta solamente durante gli orari estivi più caldi (dalle 12 alle 16). La mancanza di luce solare nella facciata Sud-Ovest è per il periodo invernale una condizione sfavorevole, ma per quello estivo risulta invece vantaggiosa.

Shading Analysis

Location: Via Enrico Cernuschi 9, ROME, IT.

Once started Vasari and opened a new file, you can change misure’s unite(“Project unite” command) under the Manage menu and set the location by clicking on “Location” in the Analyze tools.

Then you have to choice the area you want to study by typing the city name and, once found the exact location, clicking on “Import site image”

2ph.jpg

After you have imported the area, you can start modelling using the “Creat Mass” command and start drawing the perimeters of the building and extruding them. Once you finished to create and modified the volumes needed, you can click on the “Finish Mass” command.

Now, in order to study the shadings, we’ve to show the Sun path, activating it by clicking on the sun icon. Once the sun is switched on, we can activate the shading by clicking on the respective icon. We can now set the hour and the day of the sun so we can see the differents shadings generated by the daily light in different times.

Setting views

In order to get the needed views you have to click on the floor plan 2D site view in the Project browser menu; then by clicking on the Camera command you can place it as you wish, orienting the sight and choosing the deepness as requested.

After having placed the camera you can set the eye and target elevation by clicking on corresponding command in properties menu of the corrent view.

OBSERVATIONS

The lighting proposed by Vasari reflected quite accurately the real shadows projected on the N/E (A Facade) and N/W (B Facade) facades by the sorrounding buildings. We can see that this two facades don’t get sunlight untill 3 pm, when the N/W is almost totally illuminated(excluding the projections from the balconies). At 6 pm the facade is hit mostly on his upper portion. As we could expect for a facade standing northwards, the A facade don’t get light directly all day long, but it gets it only undirectly by the opposite building’s front in morning hours ( 09-12 h).

Via Pier Luigi Nervi, Latina

1. Open Vasari and click on New Metric

Punto 1.jpg

2. Click on 3D View: 3D that is in the right window Project Browser. Click on Analyze> Location to load the image of Google Maps. It will open a window where you have to write the exact address taken in analysis. Check the box Use Daylight Savings time at the bottom left of the window and click on Import. It will open an additional window in which we will indicate the level (Level 1), then click again on Import.

Punto 2 OK.JPG

3. Click on Manage> Project Unites to change the units in which the software works. In the window that opens, click on the bar of millimeters and change it in meters.

Punto 3.JPG

4. Click on Model> Create Mass to begin to draw on the contours of the building considered and use the Line tool.

Punto 4.jpg

5. After you draw the outline of the building, making sure it is closed, select it with the pointer and click on Create Form. At this point the surface created will take the form of a volume which will bring the measures of height, length and depth, then click on Finish Mass.

Punto 5.JPG

6. Repeat this process until you have designed the entire building.

Punto 6.JPG

7. Click on the buttons Sunpath On (the symbol of the sun) to recreate the diagram solar and Shadows On to activate the shadows.

Punto 7.JPG

Exercise:

The building is located in Viale Pierluigi Nervi in Latina (LT). It 'a L-shaped building, with the south-east front that includes entrances. The analysis made by Vasari says that in the morning, at 9:00 a.m., the building is fully illuminated at the southeast, and instead in shadow at the northwest, something easily seen from the photos.

Mattina1.JPGFoto mattina 1.JPGMattina2.JPGfoto mattina 2.JPG

The afternoon, at 5:00 pm, instead the east facade is in shadow and projects its shadow on the south facade, and on the court.
