[Radiance-general] RE: ECOTECT

[alexis Loubeyre]

Dear All,

@ saskia:

if the results are different, which version should i trust? 

@ Kalwall:

I've got my 3d model in Ecotect, I export my model to radiance (the grid in fact) , run the calculation and display results in Ecotect.

My model is a large floor for an office, one part of this office can't receive any external lights, my room is 30 m depth with only one side (SE) with windows.
With Ecotect v5, in the back of the room i've 0.2 where with Ecotect 2011 i've 3.2 for the DF.

Regards,

Alexis

Dear Alexis I would like to add to this topic with our findings that large differences in daylight factor calculations exist between the different versions of Ecotect. Best regards Saskia Gabriël

Subject: [Radiance-general] ECOTECT Dear Alexis,  I will say that the internal analysis methods (split flux) is not entirely accurate. I am wondering about your radiance export please explain how they are different.
