Analysis on sun light for each surface

Hi, I want to analyse all the surfaces for some buildings, but how can I use grasshopper as well as ladybug to achieve? I have already got all surfaces towards north, south etc. in grasshopper.

Thanks a lot!

This question is pretty vague but, if you want to compute the number of hours of direct sun hitting some geometry, use the LB Direct Sun Hours component. Here’s a sample Grasshopper file.

Thanks for the tips. But I want to analyse not the building as a whole, but each surface (north, south, east, west, the roof) and I’m not sure how am I suppose to do with grasshopper.

Just organize each orientation as its own branch of a Grasshopper Data Tree. Then you will get out separate results for each orientation.
