How Simulate Daylight Honeybee

Hi Everyone !

I'd like to know if it's necessary select on grasshopper just one floor to simulate daylight on honeybee. I want to simulate just one floor but I don't know how could I choose this to simulate. Someone could help me ?

I attach an exemple of my tower and a louver. And the Hydra Simulation Daylight, I don't know how to say to honeybee that I want simulate some floor of my tower. 

Someone knows?

Thanks for attention, will help me a lot!
