Geco Analyzes all zones in the file not only selected building

Hi,

I am trying to optimize shadings depth on a surface of a building in Mumbai. To do so I need a solar analysis on the façade surface using geco and ecotect.

The problem is that when I run the analysis, all zones including faced, shading, outside building and... are being analized . This significantly decrease the speed of the analysis. 

The grasshopper file is attached. I would be thankful if you let me know if there is any solution for this problem
