In order to better analyze the solar radiation on my building have added more detail to the 3D model.
Once this is done we are going to click on solar radiation.
A window will open (see photo) and we will set the date in the menu display:
type - cumulative
unit - kWh / m ^ 2 (of course, we choose the unit of measurement of our country)
style - remains unchanged
Now we click on sun study in order to set the sun setting.
Then since we want to calculate the solar radiation throughout the summer and then click on through the winter and then choose multi-day summer solar studies (solar and winter study). Finally click on ok and analyze.

South-Est summer view
Then redo the procedure for the winter analysis

EDIT: analysis of the degradation
It is noted that the main front in both winter and summer is always blue. This tells us that the sun hits just the facade. It is degraded significantly (mold and vegetation).
