Issue with facade pattern related to total incident radiation [geco]

Hi guys,

Since my discovery of algorithmic modelling I've always thought at the multiple advantages of relating it to architecture and energy simulations.

The other day I've tried to create a parametric facade with a pattern related to the value of total incident radiation calculated with Ecotect through Geco plug-in.

Everything went alright except for a problem that it's related to the way I have patterned the facade of the parametric surface.

I am sure it's something about the way I've retrieved the values for the facade pattern but I don't actually know how to solve it.

I'll attach some screenshot and the .gh file to make everything clearer.

Thanks in advance
