Prima esercitazione_Via Soragna (Acilia)_ Silvia Mezzetti

With the program Vasari I chose to analyze the solar radiation on the North-East and South-West facades in different times of the day (15th March 2014).

Actions

After setting up the assonometric view and the unit of measure with the metric system (MENAGE->PROJECT UNITS), I have imported on the base the planimetry of my area using the command below 3D cube. After setting up the plan view (MENAGE->USER INTERFACE->PROJECT BROWSER->FLOOR PLAN:2D SITE), I have started to trace, through the drawing tools, the bases of my building (MODEL-> CREATE MASS) and i have extruded through the command MODIFY. After completing all the buildings, I have finished the operation with the command FINISH MASS. Coming back to assonometric view and using the commands SUN PATH and SHADOW I have analized the effects of solar radiation on my edifice. Lastly, through the command CAMERA, I chose the prospective and, with the command SUN SETTING, I have changed the position of the sun according to the time. 

Analysis

Firstly, I have analized the North-East front. The edifice receive the solar radiation starting from the early hours of the morning and the front building does not shade my facade. From 11.30 a.m. the South-East facade does non receive the solar radiation anymore. With the going down of the sun the shadow reaches the front building (from 3.30 p.m.). It’s possible observe that widht of the road and gardens front of buidings allow an optimal distance: the edifice under analisys has a good illumination during the entire period of the morning and for this, inwardly, there is the living area with kitchen and lliving room with the balconies.  For this facade it’s possible to realize a photographic control (without visual obstructions as boundary walls) and so it’s possible a direct comparison between software and reality. I chose three hours (9.00a.m.; 1.15p.m.; 4.30p.m.) in which it was possible recognize the shadows of the buildings so defined.

The South-West front is exposed to sunlight in its entirety only for few hours daily (from 11.30a.m. to 3.00p.m.); in fact, the palace on the back begins to shade the building under analysis until obscure it in its entirety at 5.30. The orientation and the proximity between the two lots (there isn’t the road which increases the distance) has led to the realization, on this side, of the bedrooms which do not require solar radiation during the course of the day.
