GECO question

Hello everybody,

I want to do some analyses with geco / ecotect. I understand the gist of it but I don't seem to figure out how to do an analysis on specific objects in the model.

For example: i have a 3d model of an area and I want to do a solar access analysis for the roof of just one building that interests me. Then I want to output those color values and depending on hot or cold spots cluster program around them.

HOW ?
