To analyze the building I have considered the summer period (from 21/06/2014 to 22/09/2014 between 04:37 and 19:46).
And the winter period (from 21/12/2014 to 19/03 / 2015 between 06:18 and 18:18).
Looking at the analysis we can see that in the South and in particular in the South East side of the building, the solar radiation it is not very important.
