Lightshelf effect on daylight analysis result

Grasshopper Plugin

Hi all,

Working on daylight analysis and evaluating the light-shelf’s effect on daylight availability, I get two different results for the same condition.

I imported the PO model to GH and added the lightshelf to run the analysis as shown below:

And here is the result of two simulations without any change for inputs:

Any idea how to figure out why this happens?

Thanks

Hi @mahagh, we will need a sample filler to be able to help you with this question. It’s hard to tell without having access to the model and the input files.

Hi @mostapha,

I just shared the model with you.

Thanks
