I use ecotect/radiance to run Daylight factors studies.
I have a problem to set light reflectance of internal materials (floor / walls / ceiling):
- what value should I enter ? LRV value or L* Value ?
- Where should I enter that value: in the materials properties solar absorption (see picture 1) or in the color editor (see picture 2)
It changes really much the results.
I don´t know what is LVR, is not similar abbreviation word in my country. But if you want to do a interior lighting analisys the main parameters are:
- Color reflected interior
- Specularity interior
if you have doubt try to explore the parameters value of the material library. It is ever a good began.
I hope help you
