Reflectance and Transmittance issue

Post by Paul Lam »

Hi All,

I am a IESVE beginner and doing a homework for comparing the result between FlucsPro and Dialux.

When I was generating the lighting analysis calculation, the result between FlucsPro and Dialux are much different.

I found that the result always shown that "Reflectance = 0" and "Transmittance = 100". However, the "Analysis calculation summary" shown the elements such as wall, ceiling, etc. which have reflectance.

I try to use the "assign surface type" to change the "Reflectance" and "Transmittance" but it's not work.

I am not sure am I missing some setting before to change the "Reflectance" and "Transmittance"? or is it the issue of I am using student licence so the above setting is limited?
