Hi to all,
I am currently working on a radiation analysis. For this case i am using HB Annual irradiance tool, and i am trying to calculate the irradiance in W/m2 on the interior side of the glass, so to understand how much of the radiation is actually entering the room.
However the radiance modifier does not have any distinction between the visible and the whole spectrum unlike energy plus.
Is radiance considering the same transmission for the visible and whole spectrum (radiation) since there is no SHGC and VT distinction and only transmittance? If i want to consider the angle dependency of the radiation through a glass, does E+ consider this effect? what about radiance? It is quite confusing how each calculation engine (Radiance vs E+) is addressing this. I would be grateful if someone could clarify.
Thanks
