Ground reflection using Ladybug

Hi,

I am trying to calculate how much solar radiation falls on my model and would also like to include the reflected radiations from the ground. Is there anyway I can do it. I guess not, having had a look at another post which asks the user to instead go with honeybee to achieve that.

Perhaps there is another component which can achieve that?

But I do not want to do daylight analysis at the moment, but would just wan an overall picture to understand what portions of different radiations fall on my model.

Best regards,

Anurag

Hey Anurag,
As I remember, you can't include the reflected radition in the ladybug component.
But why wont you do it in honeybee? The setup is not much different and if you set a low number of bounces for the raytracing the calcultion will be pretty fast.
Anyways the reflected radition is properly a minior component in the total radiation on the surfaces.

Hi, sorry, I was in the previous conversation with Anurag.

I don't agree about the context reflections being always a minor component , as I had to work with cases that a mirrored building raised the temperatures of the north façade from the building I was working with to meet the southern ones.

However I completely agree with the advice of honey bee and the ray tracing.

Anyway, do you know how to get the solar radiation in terms of Wh/m2 from honeybee without going to the idf?
