[esp-r] Questions regarding optical properties of interior surfaces in ESP-r

[Sébastien Brideau]

Hi all,

 

I am wondering how ESP-r treats solar radiation on surfaces by default.  Is
the normal absorptivity used at all incident angle, or is there a default
directional curve that is used to reduce the absorptivity at higher angles
of incidence? Is there a way to input directional properties for solar
absorptivity on an interior surface? 

 

Also, how are solar radiation reflections treated?  It is my understanding
that only one reflection is considered.  Is that correct?  Is the reflection
considered diffuse, or specular?  Is there a way to change that default
setting?

 

Thanks for any help.
