LAB6_MONTEVERDE_SOLAR ANALYSIS

Here we are back in Monteverde with our building, we are going to test it using the Formit Solar analysis.

First of all we need to create a group in order to apply every setting to the whole unit. To do this we select all the sufaces of the building and we right click on the mouse to show a menu which contains the "Create group" command.

Once we created a group, the program shows a sort of cage that recognizes the selected volume: now every edit will have effect to the whole building.

We set the solar analysis in equinoxs of spring (in Mars), autumn (in September) and solstices of summer (in June) and winter (in December).

Four views for each period are going to show the whole status.

The test shown up is related to the equinox of spring, in Mars. The result shows a constant double side, with a medium impact of the sunrays on the South-East side and a minimum level of sunrays on the West side. The cavaedium is so deep to let the ligh to penetrate, so it will receive for almost 90% of it's surfaces indirect light.

The second test shown up is related to the solstice of summer, in June. We realize a huge level of solar energy on the roof and generally on all the horizontal surfaces. The cavaedium and the West side are once again affected by a low level of solar energy, they are going to receive indirect light almost all the day. By the way it's evident a slightly better situation for the violet/blue surfaces shown in the first test: now we are going through a hotter color temperature.

The third test shown up is related to the equinox of autumn, in September. We obtain a similar result as the first test ( equinox of spring): it's evident the huge difference between what's under the direct sunrays and what's not. The West side as the cavaedium itself, appear as the most dangerous sides of the building; even the lower part of each balconis (especially where the mechanical momentum is at its peak) need to be under control, for regular maintenance.

The fourth test shown up is related to the solstice of winter, in December. Levels of  solar energy are low on all the building, and extremely low on the sufaces on the West side, already known as the ones on the wrost possible position of the volume.
The violet result is close to the deep blue which certifies a dangerous cold surface. We are going to have a reasoning below to resume all the tests shown up.

After all the analysis we can confirm that the problem of blue/violet surfaces (cavaedium included) have to be controled every year to prevent a over limit level of humidity. This issue is probably bigger than the test shows because the building had been built in 1960 and in that times there were no attenction toward the common problems of today, as the "thermic bridge" and other issues due to the insulation.

All the structural nodes have to be protected more than the builders established when they built their project. We mean to consider especially the edges around the windows, the lower part of the balconis, the areas of connection between floors and walls.

LAB6_ROMANINA_SOLAR ANALYSIS OF THREE PROJECTS

Here we are in Romanina, on a empty area in wich to build our projects.

The selected buildings are the project we want to test. The test shown below analyses 4 peak months (in order: January, April, July, October) for three project ideas.

Project # 1: Salgado's proposal (reasoning below)

Front

Back

Salgado's project of courtyards is characterized by a 6 - 8 floors building in which we recognize a medium/high impact of the sunrays, especially on the front side. The courts are pretty always covered because of the relevant height of the buildings, that reflects a very difficult job for the sun to let the private green be illuminated. Even the two orthogonal roads which pass through the buildings are damaged by their height.

 

Project # 2: The big Cs (reasoning below)

Front

Back

The alternative proposal called " The big Cs" has a new view of the courtyard space, it is wider and more free than the first attempt., it is now formed by two big Cs that are watching themselves. The new big space let the private green area be totally sun dipped for almost all the year, letting then the space be useful for the highest number of days per year. Although it seems to have the same perimeter of the Salgado's project, it has changed the height of every part to favourite the East side, then the solar path. Values of the test shows a generally higher percentage of solar impact on the surfaces than the previous project, that due to a most free central space where to live toghether and a minor attitude to close a space into a sub unit which forms a more complicated system. Here the road left is a way less "damaged" by the buildings form than before and the whole area shows itself after the test as a more uniform  field where to work on.

 

Project # 3: East broken corners (reasoning below)

Front

Back

The third project is a more pushed idea of common courtyard usage, that reduces the internal space as a big and large square in which to develop the everyday activities. Here the test shows an even more uniform result of the solar impact, due to the absence of some parts that would have modified  the geometry, and that's the point: our intent to create a most open space than  before couldn't face the presence any other part of the buildings.  This configuration wants totally to break the first's project idea: a small courtyard  with a limited green area in the middle of it would appear as a stand alone part of a unit, which doesn't communicate with the rest of the space.

Now even the last road is no more, the actions are free, as the action of the sunrays.

LAB6_VIA BALESTRA (MONTEVERDE)

Here we are in Via Balestra (in Roma Monteverde) with the selected model among the nearby buildings.

 

 

The digital render has been tested in three different times of the day, starting from early morning (7.19 AM, cloudy sky), through midday (13.36 PM) to afternoon (16.31 PM) and showed pretty similar shadows in every condition.

Here's the chronological order of the analyzed scenes, then the final considertions.

As shown, we studied the three scenes in top view and in 3D model view, we realize that the indirect light is ready to work on the two facades even if we are under a cloudy sky. The sun starts rising and produces very long shadows that cover the  North - South oriented main street (Via Balestra), while the two orthogonal ones are already illuminated (Via Revoltella close to the North front and Via Vidaschi close to the South front). It's a huge shame that the East front doesn't receive the direct morning light, because of the pretty close building in front of it; the following scenes confirm the constant issue during the whole day.

When we approach to midday we see from both views that almost all the area is illuminated and shadows don't go upon the close buildings. We also see the exception of Via Revoltella, that is still covered by the shadows of the buildings it drives along. That is due to the form of the path, a long  and strict climb that will never see the sun over it.

The choosen building looks like it is dazzled by the sun on the South - West front and that no artificial lights have to be turned on until we pass the afternoon.

Spring time helps us to be right about our reasoning: even if shadows begin to get longer, the building still holds the privilege to be fully hitted by the sunrays, while the North and the East fronts have no way to reach direct light (certainly known for the North side, but at the same time not so good to think about for the East side).
