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.

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).

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.
