One of the LEED v4 Quality View Requirements


I have a question regarding “Multiple lines of sight to vision glazing in different directions at least 90 apart” which is one of the LEED v4 Quality View requirements.

I don’t quite understand why the results are different when I change my building orientations. I think that orientation does not matter in this situation.

I used the same python script from Hydra (given by @chris), so I assume that my post-processing part is not quite there yet. Can anyone help this? Also, does anyone have an idea to get the same result using native grasshopper components instead of a python script? Quality View (406.0 KB)

Much appreciate it.


Hi @seung,

Could you test this? I have tried to replicate test you need using VPL, but I leave to you to study it.
Basically this component generate N vectors for each test point:

Maybe it is this what you need:

Hi @AntonelloDiNunzio,

It makes sense now.

Thank you for your help, much appreciated.


Hi @seung and @AntonelloDiNunzio

Your script helped a lot. I wanted to ask you if you managed also to have separated results in case of the analysis is performed on more than one room.

I tried to modify the flatten/graft option but didn’t end well so far.

Thanks if you can help me.
