[Radiance-general] Glare Calculation

[alexis Loubeyre]

Hi Jack and Thomas,
 
Thank you for your help, I tried evalglare yesterday and he worked well.
But regarding my results have got couple of questions:
 
- i'm doing a glare study for an office (10m depth). I think glare will not be a problem for a person located at 9m away from the window, isn't it?
- when my calculation is completed, i've 2 warnings messages:
        low brightness scene
        vertical illumiance < 380 lux.
Do they impact the calcul?
So should i proceed a glare study only for the first 5m from the window?
 
How can i fix the warnings?
 
 
Regards,
 
Alex

Hi Alexis,

How did you set up your view for RCP_c3.pic? Findglare expects a fisheye (180h x 180v) view. If it does not get it then it reports an error/warning message.

Note also there is the new program evalglare for glare analysis:

 Hi everyone,
 
 
I'm doing a glare study with radiance and Ecotect.
 
Fristly i've created my 3d model in Ecotect, then i've exported it in radiance to calculte the lumiance in cd/m².
No problem for this part.
 
Secondly I'm using the function findglare and then glarendx, to compute a glare index. 
When i'm writing my function findglare in my command window like this: findglare -p RCP_c3.pic > glaresult.glr
I've got en error message: "findglare: picture read error"
 
or if i'm using the method glare, i've got the same problem: "must have view or picture"
 
How can i fix it?
 
Thanks for your help,
 
Regards,
 
Alexis Loubeyre.
