Hello,
I am working on a design for my house 
I am planning a solar heated floor, I am getting contradictory informations on the best orientation of the panels so I wondered if I could use radiance to model them and make a simultaion of the infrared absorbtion of a panel. had any one already done such thing ?
regarding IR absorbtion by the panel I have read that the IR rays once passed through the glass are partly absorbed, partly reflected but that the reflection is not completly reemited through the glass but refracted to the black side of the panel. would a glass material take this in count or do I have to use a a dielectric and an interface or a BDRTF ?
