NC-2009 IEQc8.1:Daylight and Views—Daylight

Daylight calculations with Design Builder v3

Dear All, I am using Daylighting module of Design Builder V3 for IEQc8.1 daylight calculations and it gives very different results (less light) than the calculations conducted with Ecotect+Radiance. Does anybody have had any experience with Daylighting with DB v3?. I am also wondering where can you modify de surface reflectances, Does anybody knows how to do it? Many Thanks Felipe

I am not familiar with DB but as I heard it uses the radiance engine as well. The different between two tools may occur because the translation process from the input to the radiance file. If you can take a look the radiance file generated by two software, you can compare both and see whether they are same.
