After the first stage of analysis that took in view the projected shadows by buildings in Vasari and in reality, the second step was been the SOLAR ANALISYS.
In the ANALYSE menu I had clikked to ECOTECH SOLAR RADIATION, appeared the window of setting and here I had choosen the mass faces to analyse, the solar study and the type of radiation.
I started with a single day study in CUMULATIVE
analyse the radiation at 8/04/2012
Then I had analysed the radiation during the spring
there are two points where the solar radiation is almost nothing, and I had compared them with the actual state in the biuldings
the combination of a strong and rising humidity with the low solar radiation it's the cause of the plaster' s detachment
