Light Reflectance

444 Views, 3 Replies

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.

OK. THank you.

 

But I have the LRV value of a material.

Where do I enter it ?

In solar absorption (1- LRV ?) or in colour (reflect.) ???

 

Thanks

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
