Difference between Infrared/Thermal radiation material properties
Hello, My doubt is very straightforward :
For materials, it is need to specify :
Semi-transparent : Solar/Visible/Infrared Transmitance/Reflectance and Hemispherical Emissivity and for
Opaque : Thermal/Solar/Visible Absorptance
From the point of view of the OpenStudio calculation engine, Are there any difference between Thermal and Infrared ?
I am confused, because some literature considers the Sun spectra with Visible and Infrared wavelenghts, and with Direct and Diffuse components.
Any thoughts about are very welcome thanks.
Other doubt : Way is not need to specify the emissivity for opaque surfaces?
@amscosta what simulation tool are you using? Please mention it in the title or body of your post, as well as add a tag so that others can provide better help.
