[Radiance-general] how to 1) simulate reflected solar radiation and 2) longwave radiation from heated surface

[Greg Ward]

Hi David,

I can't think of anything off-hand that would suit your needs, but perhaps there are others on the list who will have suggestions.

Best of luck,
-Greg

It is also tricky to separate components, such as distinguishing what came from building surfaces from the sky component.  Again, there are ways to accomplish it, but it's an advanced task and there would definitely be some debugging involved.

>> May I ask if Radiance can simulate the following:
>> 
>> 1. the amount of solar radiation (both direct and diffuse) receivable for a given point that is reflected from a given nearby surface, e.g the amount of solar radiation at the centre of a 10x10 courtyard and 2m above ground that is reflected from the building surfaces facing the courtyard. 
>> 
>> 2. the amount of longwave radiation received on a given point contributed as a result of a nearby surface that are heated by the sun,

>> Thanks!
